Question
I’m trying to locate the current manufacturers of Williamson furnaces
(who went bankrupt in the late 80s). The reorganized company is now in
Massachusetts ( I think). Does anybody know their new name and phone
number?

Thanks.

Answers

Williamson is owned by Metzger Machine, Milwaukee WI

Phone is 1-800-736-BEST

They have some parts for older units but most ended up at a liquidator in
Lebanon IN (800-428-4339). Metzger still makes the Williamson Gasaver CTL
and TempoMatic oil burner units but most of the stuff is Goodman with a W
on it!

Associated Williamson Furnace Question:my williamson oil furnace is only blowing out cool air whats my problem?

• Answer:The burner is probably locked out for some reason. Should be a reset button on the burner. If it runs after resetting but locks out again there is some problem, do not keep resetting because fuel may accumulate in the chamber if there is an ignition problem. Call a tech for service. Its blowing cold air because your blower is probably operated by a timed control that starts when the heating cycle is suppose to start.

Associated Williamson Furnace Question:How do you light a pilot on a Williamson 5 in1 model C110-03 furnace?

Associated Williamson Furnace Question:1979 Williamson 5 in 1 furnace;honeywell T8082A thermostat?
The blower doesn’t seem to have strength even after belt was changed and curious if thermostat needs replaced or whole system.

• Answer:The furnace is 30 years old it probably should be replaced. At the very least have a technician check the heat exchanger to be sure its not cracked or leaking ( odds are it is ) as this could cause carbon monoxide to be forced into the house. If the heat exchanger is ok then he can check the blower motor and blower fan as well. None of these problems has anything to do with the thermostat.

Associated Williamson Furnace Question:fan keeps blowing on house furnace?
have a williamson temp-o-matic oil burning furnace. recently ran it out of fuel oil and had to bleed the line, got the furnace going but now the fan runs constantly and shortly after the heating cycle stops it blows cold air into the house since it is in the basement. shut the power off to furnace in hopes of it resetting itself, didnt work my other option is to shut fan off completely.

• Answer:It sounds like the thermostat fan switch is set to ON instead of AUTO. If not then hopefully you have a wiring diagram and can trace the point that is supposed to be open to kill the fan and then can determine the failure.

Associated Williamson Furnace Question:Whats wrong with our gas furnace?
Its a OLD furnace. Its been there ever since my mom has lived in the house which is about 32 years ago. And it seems that it will go off and wont turn back on again. So then I have to push the reset button and it will go on. Sometimes it will work normal, and then other times I will notice it gets cold, and then I will adjust the knob on the furnace and it doesnt turn on, so then I go hit reset and it turns on. Its probably a furnace from the 1960’s. Its a Williamson Gas furnace. And its green. We just replaced the filter yesterday. BTW im only 16. Im not 32 LOL

• Answer:What is this reset button you are pushing, where is it located. Need sonme more info to be able to help you out. You can contact me via the email

Question
I have recently acquired a small furnace that I plan to use for heat
treating….
I would like to better control the heat in this furnace to allow
settings between the current settings.   Not being an electrical type,
I do not know the best way to cheaply control the temperature.   My
two thoughts are a resistor device of some kind, or a Variac.   Short
of a professional (expensive) temperature controller, what should I
look into?

Answers
A Variac, some type of suitable thermometer and exquisite patience
should work. The <$20 Condar model 3-19 woodstove flue thermometer
reads up to 1700F with 20F resolution. You could use a kitchen timer
to time the full-power warm-up and then set the Variac to some lower
holding setting while the part catches up. Make some trial runs using
a magnet to detect the metal’s Curie point and record the Variac and
thermometer settings to calibrate them.

After you have fussed with manual temperature control you’ll see why
people recommend the PID controllers. If you aren’t an “electrical
type”, stay away from homebrew high-power resistor circuits.

Associated Top Furnace Question: How to clean A/C A-coil on top of furnace?
Do I have to disconnect freon lines? Do I have to cut access in plenum? Use water,cleaner, vacuum?

• Answer:You don’t have to disconnect anything. You will have to cut out a panel for access but I’d strongly recommend using a self rinsing coil cleaner (about 5 bucks at home depot) as oppossed to a brush. Don’t risk tearing the fins up. Keep them nice and straight. The self rinsing cleaner will just run off removing the dirt build-up and run out the condensation drain.

Associated Top Furnace Question: Should I replace gas furnace with Monterey top vent gas wall furnace?
Wondering how efficient from basement to ground floor they would be. Would one be needed on each level? Is there duct work needed?

• Answer:The top vent furnaces are just glorified room heaters. They are not really made for duct work, to heat an additional room you would need to use fans and it wouldn’t work very well. Yes you would need one for each level.

Associated Top Furnace Question: Pellet Stove vented near top of Gas Furnace exhaust, can I do this?
I need to set up my wood pellet stove. The garage with my Natural Gas Central Heating unit is just on the other side of the wall. What I want to do is run the pellet stove to other side of the wall, then up and close to the ceiling put it in with the Natural Gas Central heating unit exhaust pipe very close to the ceiling. If it joins close to the roof is there a problem? These pellet stove emit very little smoke at all.

Associated Top Furnace Question: Why is there excess steam coming out of the top of my gas furnace chimney? It’s so thick it looks like smoke?
This is causing a lot of condensation and has for a long time. I recently had the chimney relined and there is still condensation coming through walls in the house where the chimney passes through. How could the flue gases be venting up the chimney outside of the new liner inside the chimney?

• Answer:when a chimney is relined,usually with a flexible metal pipe,the “flue gases” should no longer come in contact with the masonry walls of the chimney…call the company back that did the work,something is wrong……as far as the “steam” being thick like smoke,might be normal if very cold outside… i assume your furnace is 80% eff or less and vents with a metal pipe ……if the furnace is 90%+eff,it should vent with a plastic pipe,and NOT to a chimney……dan

Associated Top Furnace Question: Should I be concerned about ice forming at the top of my chimney for my furnace?
Michigan here with temps falling to ZERO. On the downwind side of the chimney cap ice is forming and slowly making a huge icicle.

• Answer:Number one: You didn’t say what you were burning with: Gas: Oil: what fuel? This is simply condensation from the heat, your getting extra condensation from the fuel your using. If it were wood, I’d say the wood is to “green” you need dryer wood. This has been an exceptional winter, with the wind, the below zero wind tolerances. Special care has been needed to care for the heating of a house. Check with your fuel supplier and see what they have to say. This could be corroding the inside liner of your chimney and making it easier for the cement grout or the liner to crack, allowing the fumes, smoke and even the fire if there were a chimney fire, to enter the house, mine burned down this way.

Associated Top Furnace Question: Older Rheem furnace stops working and I have to keep pushing the restart button under the top panal so my heat?
I changed the thermostate but it keeps doing it and now some times it smells like its over heating.

• Answer:If its a really old furnace (10 plus years), it could be a roll out switch. This happens when your furnace gets too hot. The roll out switch keeps anything from catching fire. You could check your filter but it probably means one of two things. Either your heat exchanger is bad, or your A-coil is dirty and needs cleaning. Both have to be done by a professional. An A-coil cleaning is a simple service call, where the heat exchanger replacement is a major thing and it may be just as much money to replace the furnace. A good way to tell if it is your exchanger is to remove the panel and watch the burners light. The flame should go straight into the hole and not “roll out” on any of the sides. If the flame doesnt go straight in, it is the heat exchanger. The A-coil being dirty restricts air flow so your furnace retains alot of the heat instead of passing it out into the room, consequently makeing the furnace too hot and tripping the roll out or thermal switch as well. Hope I helped….

Question
My old oil furnace died this week and I obtained several estimates for
a new high-efficiency gas furnace.  However, I have heard conflicting
stories about the “ranking” of the brands.  Several competing salemen
have told me their brand was top of the line.  What are the
net.opinions on these brands:

Answers
I just replaced my furnace and central AC last year. What I heard from
every single rep, except one, was that everybody else’s furnace had problems.
Some of the problems were major some minor. The only thing all of them said
that was the same was that Janitrol was not any good at all. I dont know if
this is true or not, but it was by far the least expensive unit , sometimes
less than half the price. I tried to compare apples to apples. My base for
comparison was; a 10 SEER AC and a 70% efficient furnace. Of course nearly
all of them tried to push the more efficient, more expensive units.

Lennox: old name in the business, lots of local reps in my area. Their sale
pitch revolved around payback time. Funny thing is the guy had a
“computer” that figured this out for you. It figured in the
efficiency of the old unit and the new unit and the savings from
using the new unit and how long it would take to pay for itself.
Well after using this computer, it turns out that no matter what
efficiency unit you buy it takes 5yrs to pay for itself. They must
have planned it thay way when the computer was programmed or the
prices were set by the company. Naturally they pushed the most
expensive model. They offered an average warranty at an average
price. They were my second choice.

Heil:   Also known as Whirlpool, Sears, and TempStar. The one rep who didnt
badmouth the others sold TempStar products. He was a one man outfit
and was the least expensive (except for the Janitrol). The main
reason I bought from him was he was the only guy I talked to that
seemed to honest. Also the equipment looked to be of decent quality
and since it was the same product that Sears sells, I figured that
Sears would service it if need be and Sears will allways be around
if I need them. His price was a thousand dollars less than Sears.
I would could consider this equipment to be of average quality also.

Carrier: These guys had the worst reps in town. I tried four different
Carrier dealers and only one actually came out to estimate the job.
The guy who did come out was the sleaziest of all the guys that
I talked to. This guy also sold janitrol. His said that Janitrol
was of a lesser quality than the big names, but he still sold it to
poeple who couldnt afford Carrier products. Is that the way to sell
or what ? This guy didnt have a brochure on the product or any
other written info either. I have no idea how good the equipment
is, the warranty was average and so was the price.

Trane:   Really expensive, Really really expensive. Offer a great ten year
all inclusive warranty, if you pay for the second five years. No
kidding , the really smooth sales rep pushed how great this ten
year manufacturers warranty was. It sounded great and I thought
“now there is a company that stands behind its’ product”. When I
looked into the guys price guide, there were two columns. One for
the 5 year warranty and one for the 10 year warranty, some deal.
It’s possible the sales rep mislead all on his own, and this
definetely turned me off to the product this guy was selling.
Trane has fabulous brochures, great cutaways of the equipment
and high quality printing. I’m sure that’s part of why the Trane
stuff was double the price of of the others. Also the Trane guy
“a special lineset for the a/c unit” that had to be used that wasnt
part of the original bid for an extra $200. When my Tempstar was
installed this cost 50 dollars and wasnt a surprise add on after
bid was given to me. Impressive looking equipment, expensive
and a good 5yr warranty standard.

Well, as you can tell I went for the product with most honest seeming sales
rep. It’s been about 5 months and I’m very happy with the equipment.  One
other thing, all of the dealers said that were not used to some one shopping
around. Nearly all of their customers were in desperate situations, such as
no heat in December or no AC in August. They did not like the fact that I
was getting bids from other dealers. All except the Tempstar guy , I guess
he knew he would beat their prices and still make money. And he did.

Associated Top Furnace Brands Question:Buying new Goodman central heating and air-conditioning units?
I have a 2700 square-foot house in Southern California, and I am replacing the builder supplied AC and furnace units. The top brands Lennox and Trane are beyond my budget, so the contractor is recommending Goodman, which is one of the largest manufacturers of this equipment. Consumer Digest rates them a best buy for the “budget minded” consumer. Could someone knowledgeable on this subject comment on the quality of Goodman.

• Answer:Hi, I just installed a 3.5 ton AC and heat…..Been using the air and works great….could see the savings right away… The furnace will be next…. how the ac worked I have no worries.. So far Goodman has been great! Get the Goodman warranty with it to… Very cheap and covers everything. Good luck I hope this helped! Mike

Associated Top Furnace Brands Question:What does it mean if my furnace is making a choking sound?
I just moved to a brand new home, and whenever my furnace runs, it often makes what can only be best described as a “choking sound”. It stutters, over and over, yet does work. Is this a problem, and if so, how do i resolve it? Further, my heat is real lousy in the top floor; it comes out nice, but not hot! Is this related?

• Answer:Could be running out of fuel, have plugged jets or plugged fuel filter or the firebox is coming apart…a good weekend project or time to call the furnace man.

Associated Top Furnace Brands Question:My condo always feels colder than thermostat says it is. Time to change the thermostat?
I live on the top floor of a 3-story condo and my (programmable) thermostat on average has been reading in the high 60’s, low 70’s, yet the rooms always feel cooler than the temperature readout. My furnace is brand new but I kept the thermostat that came with the place. The furnace will kick on if I raise the thermostat, but if I keep to a reasonable schedule programmed into the panel, the furnace will never cycle on.

• Answer:No. Buy a room thermometer and see how the results compare to the thermostat.

Associated Top Furnace Brands Question:New part, or brand new furnace?
Our heat stopped working a few days ago. The furnace is probably close to ten years old and is not a very top-quality one. Our home is approx 1500 sq ft. The repairman came out and checked everything, and said it needs a new valve. He said he wasn’t sure of the price of the valve, but said it could run a couple hundred. Our other choice is to get a brand new furnace (and of course he recommended the highly $$$ Trane furnaces). I’m getting a quote on this new part, and I think a couple hundred for a very small part is outrageous, but if it is in fact expensive, is it better to just install a brand new furnace? We will be in this home for close to a year or so but after that will move. Any tips will be helpful!!

• Answer:Repair it, replacing it will drag in more and more complications until you end up spending a lot of money replacing half the system. The answer might be different if you were there long term, but under the circumstances you really just want a repair. Gas valves are $100 to $120 for the most part plus labor to install (and it really isn’t a do it yourself job). So, $200 seems about right.

Associated Top Furnace Brands Question:If we’re not happy with our new $12,000 Trane oil furnace, what can we do about it?
A little under 3 months ago we had a brand new Trane oil furnace/AC combo installed by Total Heating and Comfort and we’ve had nothing but problems from day one. We were promised a 2 day install tops and yet it took 3 and a half weeks. We were told that we wouldn’t be able to hear the furnace or the blower/fan kick on and run even though the furnace is installed in our hallway (we don’t have a basement). The damn thing sounds like a diesel pickup truck running in the middle of our house and that’s even before the blower/fan kicks on. A part was broken on the BRAND NEW furnace unit the day it was delivered so that alone added 4 days to the install time. On top of that, our oil tank is outside so it would get so cold the pump inside couldn’t suck the fuel into the furnace. Various techs from Total Comfort came out about 7 or 8 times and scratched their heads saying they didn’t know how to fix it so they finally called the master Trane tech in Richmond, VA. He sent another tech out who installed a device called a tiger loop that heats the fuel an extra 35 degrees before it hits the pump so it will be the right viscosity. Well, that was 3 weeks ago and now our furnace is dead again. I went out and checked the fuel gauge and it showed that we’re just under the half mark so I know we’re not too low on fuel. My question is, can we just tell Total Comfort to take this piece of crap out of here and give us an electric furnace? I’d be much happier paying $300-$400 a month for our electric bill if it meant we actually had some damn heat. In the 3 months we’ve had this unit, we’ve had heat for maybe 6-7 weeks. Any advice on what to do would be appreciated.

• Answer:Yes I would do exactly that. In addition to telling them to take it out and put in an electric one, list in detail, just as you have done here, all of the problems past an present and after calling them to tell them this I would put your compliant in writing and send it certified mail so that you have a signature to the installing company. Tell them exactly what you want and that you don’t want to pay for anything to do with this equipment or disruption to your lives. Then I would also call or write TRANE customer service with the exact same complaints. Many times the manufacturer will get things taken care of because they want to keep their good name. Also if you do not get satisfaction from the company doing this install, take your complaint to every organization you can, such as the BBB.org, Angieslist.com etc.

Associated Top Furnace Brands Question:Will my furnace not work properly if the batteries in my thermostat are almost dead?
We woke up this morning and it was 60 degrees in our house. We had the thermostat set on 75 the whole night. We have a brand new furnace (installed a few weeks ago) and I’m bummed it’s not working properly. I live near Chicago and it has been in the sub zero’s, but it shouldn’t be THAT cold in here. I noticed this morning the thermostat, although on, said at the top “replace batteries”. I did that.. should I expect it to get warmer in here? Can the furnace not work properly because the thermostat has bad batteries?

• Answer:I don’t know your exact situation but usually the batteries are there simply to maintain the memory of a programmable thermostat during short power outages–the thermostat is running on low-voltage power from the house system, not the batteries, so low batteries wouldn’t be the problem. Maybe an HVAC pro could confirm this with a post. So I’d suspect two other possibilities. The weather is so cold that your furnace simply can’t keep up with the weather, in which case it might have been undersized or maybe your house is not well weatherstripped and insulated. Or maybe the furnace isn’t quite working properly yet, in which case you should have the installer come back to tweak it.

Associated Top Furnace Brands Question:Top 5 heat pumps? Anyone know?
My heat pump which is used to both heat and cool my home is 15 years old and will soon need replacement. I would like to know the most reliable and reputable heat pumps brands that are available. I am told that since my system uses freon, that both the outside heat pump, as well as the inside furnace unit which partially uses the heat pump for heating in winter, will need to be completely replaced because it uses freon which already is, or will soon will be, banned for environmental reasons. The inside furnace unit runs on an electric coil strip to add the extra heat which the heat pump cannot supply when it gets too cold outside in the winter. Will the entire set up need to be replaced? And what would be the approximate cost of this total replacement? Thanks…

• Answer:Cost in a given series is based on BTU, the cooling or heating capacity. (Sometimes they use “ton” but I think that’s not used now) Good brands are Carrier, Trane, ..I forgot the rest. You need to find several local reputable dealers and ask for estimates. You probably need duct work re-done or at least the leaks and insulation repaired. The size of your house, the leakiness of your doors and windows and the insulation in your house all have to be considered before the proper size (no. of BTUs) can be selected.

Associated Top Furnace Brands Question:95% Goodman GMV furnace won’t stay lit, code 3?
:brand new goodman gmv furnace 2 stage 80k and 115k was running ok after craigslist install, don’t have much money. now though less then a week later it lights up then the flame goes out after 1 to 20 seconds randomly. In trying to figure out what changed I can only say… 1) it rained 2) I closed a vent 3) I messed with thermostat (so stupid!!!) 4) its gotten colder in general 1) I mention rain because I noticed the vent going outside has some water in it looking down it from the outside. it runs through the wall not quite level but with the open end a bit higher so I cannot see how it could avoid recieving some rain water. the installer had the purple glue stuff on the end of it outside like he was going to add a peice to the end maybe to protect it from the rain but I don’t know. I did notice when the furnace was running (no flame) water coming out of the chimney thing outside. I should mention there is only one hole in concrete block, they said they were going to try some ‘new’ venting method thing where they only had to run one pipe. So 2 white pipes come out of the furnace and run to a ‘Y’ like thing to one pipe going through the wall. I looked down the tube outside and only see one pipe so I’m pretty mystafied about that one. 2) I closed a vent to an unused room. the guy who installed it used 6 inch flex for the vent runs and the furnace was very powerful maybe not enough vents? There are 10 vents all with 6 inch flex duct but 5 are nearly completely closed to force air to the other side of the house. ran ok before though so I don’t see how that could be it. 3) I read the white rogers thermostat manual and changed some settings. I think I changed them all back after pulling out the batteries and cutting power to the house but not sure about all settings. I read that some anticipation setting is automatic with digital thermostats so that should be working? The thermo has only 2 wires as wires were not changed during upgrade. ran fine for a week… 4) Its gotten a bit colder out and the duct work the guy did is not too good. the house has a finished and insulated top floor and I’m still using the old, very large, return air duct work. However he put in new, not air tight duct for the hot air. the bottom floor has no rooms or walls or insulation, it is concrete block and thusly cold air from downstairs (where the furnace is) is being sucked into the return air drop he did and especially the filter area which is too big. His duct work also shoots some hot air meant for upstairs out downstairs. when it was around 60 degrees downstairs it ran ok but now that it’s colder it’s not staying lit. however at the warmest time of day now the temp is the same as when it ran ok and it still will not stay lit so I don’t think ductwork or temperature is the prob. So thats all thats changed since it was working right. I know for sure it was running ok before I messed with the thermostat changing settings but not sure thats when it stopped working. As to what I see the furnace starts up, flame lights and then after just a few seconds it goes out. If the doors are screwed on, when the flame goes out there is a very signifigant air pressure change inside the furnace as I can see and hear the door bend and a gush of air. with the door off this is not noticable. Also the red LED flashed 3 times after the flame goes out. It then all restarts light the flame again only to kill it and flash the LED 3 times. Perhaps most telling (I don’t know, guessing here) is the flame itself seems maybe not to be shooting hard enough. It’s not all in the duct work area but has come back enough that there is a solid line of flame closest to the front of the viewer. I’m guessing the gas is weak and the flame is being detected where it’s not sopposed to be and some heat sensor is shutting it down. I tried adjusting 2 screws and 2 hex things that were all next to each other attached to the gas line but they were all already turned all the way up. So thats the situation. I kn ow the drain is not clogged, not sure whats going on with the intake but the flame still goes out with the panels off so maybe that answers that. code mentions pressure switch problem but I don’t know how to diagnose or fix. everything is brand spanking new though. If anyone can offer some advise you’ll be warming a cold family so thanks a ton in advance… nothing about flame sensor in the error codes, talks about pressure switch but not sure which one or how to fix. will work on your suggestions first thing in the AM and thanks so much for them – still accepting suggestions…

• Answer:Sometimes on the Goodmans, when the flame goes out after just a few seconds, it could be the flame rod. Heres what you do. Pull off the top door, underneathe the burners there is a wire (i think its blue) that goes to a little rod that sticks up into the burners. Take a 1/4 nut driver and remove the screw holding that rod up there. Take some sand paper, steel wool or maybe even some emery cloth and rub it on the rod, you are basically cleaning it. Make sure you wipe off the rod to ensure there are no particals left on it. Put the rod back in, tighten the screw, and try to start it and see what happens. Another thing you might want to check, is make sure there is nothing blocking the exhaust pipe. Also check the little hoses that go to the pressure switch, pull them off and blow into them, and make sure they are clear of any moisture or debris that may have gotten in there. Good Luck

up about 2″ around each side to about 45 degrees and braze the
corners. into your emergency tray goes the driest of driest sands to
about an inch or so depth. in the sand you make swirl marks with your
fingers.

when you have the realisation that a crucible is letting go you place
it in the sand tray, or you pour it out in the sand tray.
that tray is the only dry safe place that you can dump the molten
metal.
if you drop it onto the ground any moisture that is present will flash
to steam instantly and explode the molten metal into a hand grenade.

I use a salamander crucible usually. In australia they also make a
fireclay crucible that is a single use item in the gold assay
industry. they are just a couple of dollars – cheap as chips. I have
used one for 18 months on a regular basis doing aluminium castings.
when one of these guys gets damaged and starts to come apart Terry’s
sand trays are worth gold.

hydrogen embrittlement was a big bogey man in home castings but it is
easily understood and conquered.
just as salts dissociate in water to become their component ions water
itself seems to do the same sort of thing in aluminium. the hydrogen
can be absorbed by the molten aluminium in amazing quantities, the
oxygen becoming oxide dross on the surface of the mix.
cooled solid aluminium has no ability to hold hydrogen and it comes
out of solution in bubbles through the metal.

the ways to conquer this: make sure all the metal you melt is bone
dry. cast on low humidity days.  if you notice lots of dross coming to
the surface you should purge the mix with an aluminium chloride tablet
plunged to the base of the crucible in a stainless steel wire cage.
this also dissociates in the molten metal and the aluminuim joins the
pour. the chlorine bubbles up combining with the hydrogen to vent off
as hydrogen chloride gas. if you get a wiff of this it is unbelievably
pungent and combines with moisture in your nose etc to become
hydrochloric acid. it does however do an incredibly good job of
purging the hydrogen gas from the mix.

ok two points done.

this one is a freebie. if you find that you need to make a metal mould
to get the fine fin detail, a cheap as chips mould release is as close
as a wax candle. light the candle and play the flame over the inside
of the metal mould and coat it all in soot. I’ve only used small metal
molds for model engines but I’ve never had the aluminium ever get
through the soot release to bond with the mold.
I’m sure veedubber will appreciate the sheer economy of that tip.

Question
Anybody got a date for the ruck this winter at Pine Grove Furnace

Answers
I found it   -  For all, it’s the last weekend in Jan. 2002  Fri – Sunday

Question
I would like to hear from anyone who is successfully melting small
pours of cast iron – say up to 5 or 10 pounds – in a gas fired
furnace.  At least one supplier of small melting furnaces advertises
capability to melt cast iron, but I have yet to see one in action.
Dave

Answers
I routinely pour castings up to 25 lbs in cast iron using a propane
fired Reil burner.  Works very well.  Takes about 55 minutes from a
cold start to brilliant orange pour with ambient air at 78 deg f.  I
have been using the same home built crucible furnace for two years,
haven’t rebuilt it yet.   I use a #10 silicon carbide crucible (yields
about 25 lbs cast iron).  A crucible is good for about 40 sessions.

A common misconception is that carbon content is the sole cause of
hardness in pouring cast iron.  Although a certain carbon content is
required to produce hardness, the rate of chill is also important.  If
one lets the casting cool slowly (anneal), one can routinely produce
high carbon castings that are a joy to machine.

Before you build anything,  a few comments:

Although I own most of C.W. Ammens’ books I would not recommend
them to a beginner.  Especially  the Complete Handbook of Sand Casting
(ISBN 0-8306-1043-X).  The information content is low, anecdotal and
confusing.  Having said that, I enjoy the stories he tells of a bygone
era , well worth having for the historical content alone.  For the
complete novice, Lindsays Secrets of Green Sand Casting (ISBN
0-971914-08-2)  will give the reader an excellent overview of the
_process_, especially if augmented by Lindsays other book, Wood
Pattern Making (ISBN 1-55918-205-9).  Then read the U.S. Navy Foundry
Manual (ISBN 1-55918-007-2)  to tie things together.  Now, after
reading the forgoing books you will have the foundation to use the
information contained in  CASTINGS by John Campbell (ISBN
0-7506-1696-2).  Hands down the best text I’ve read about making sound
castings.

Two other books in Campbells’ class are Principles of Metal Casting
by the American Foundrymans Society (get an older edition, geared
toward a small foundry) and Elementary Metallurgy and Metallography
by Shrager (yes it was written in 1961 but unless you can read
tunneling electron micrographs, xray crystallography and enjoy lots of
calculus, the newer texts are not going to help).

Paraphrased from Shrager chapters 9, 10

As far as influencing the carbon content of cast iron ,  before the
basic Bessemer process replaced the open hearth furnace,  foundries
would often have a large cupola furnace feed directly into
an open hearth furnace where limestone and iron ore (basic process)
would be added to make silicon, manganese, phosphorous and to a lesser
extent, carbon migrate into the slag as oxides.  The bulk of
migrating carbon goes up the stack as carbon monoxide.

The beginning caster may replicate this by tossing in limestone, raw
ore and a little ferrosilicon to influence the cast iron  melt.  I
built a  10 inch bore cupola furnace for cast iron that produces 20-35
lbs every 6-7 minutes.  Most goes to castings but some gets tossed
into the crucible furnace for _refining_ as described by Shrager.
Some really odd iron has been produced this way (g).

Chapter 1 of Campbell goes into exquisite detail about contamination
of  liquid metal by gases.  Especially the soluablitiy of hydrogen in
aluminum for aerospace alloys.  Hydrogen is less of a problem for
iron alloys and is usually dealt with by vacuum degassing for critical
applications.

Problems with the hobby caster getting temps to melt cast iron are
simple but often difficult to overcome.  I have made just about every
mistake (search back about 2 years).  In general, you need lots of
BTUs to melt iron.  This means lots of air, lots of gas and good
insulation, not just refractory.  Small furnaces lose proportionally
higher percentages of btus than larger furnaces,  Did I mention that
you need lots of BTUs to melt iron?  My first attempts to melt cast
iron were pathetic.  Look for the Monster burner modification the reil
burner and scale it to your furnace.  Next, make sure that you have
enough thermal mass in your furnace to retain some of those expensive
btus going out the stack.  Wear appropriate safety gear, eye/face
protection, boots, aluminized/leather  apron/leggings/sleeves and
gloves.  There is no such thing as a minor foundry accident.

Finally, consider lurking at : hobbic…@yahoogroups.com  .
Really good people with a high number of honest to goodness
foundrymen,  not just amatuers like me.

Associated Open Hearth Furnace Question: What is the difference between the Bessemer converter and the open hearth furnace?
The subject is Mechanical Technology.And also list the disadvantages and advantages of the bessemer converter and open hearth furnace, PLEASE and THANK YOU. (im just being polite)

• Answer:The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. The process is carried on in a large ovoid steel container lined with clay or dolomite called the Bessemer converter. The capacity of a converter was from 8 to 30 tons of molten iron with a usual charge being around 15 tons. At the top of the converter is an opening, usually tilted to the side relative to the body of the vessel, through which the iron is introduced and the finished product removed. The bottom is perforated with a number of channels called tuyères through which air is forced into the converter. The converter is pivoted on trunnions so that it can be rotated to receive the charge, turned upright during conversion, and then rotated again for pouring out the molten steel at the end. A blast furnace is a type of metallurgical furnace used for smelting to produce metals, generally iron. In a blast furnace, fuel and ore are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the bottom of the chamber, so that the chemical reactions take place throughout the furnace as the material moves downward. The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace. Blast furnaces are to be contrasted with air furnaces (such as reverberatory furnaces), which were naturally aspirated, usually by the convection of hot gases in a chimney flue. According to this broad definition, bloomeries for iron, blowing houses for tin, and smelt mills for lead, would be classified as blast furnaces. However, the term has usually been limited to those used for smelting iron ore to produce pig iron, an intermediate material used in the production of commercial iron and steel.

Associated Open Hearth Furnace Question:What are the advantages and disadvantages of the Bessemer converter and the open hearth furnace?
The subject is Mechanical Technology.

• Answer:The Bessmer converter was for converting cast iron to steel by oxidizing the excess carbon. It produced the steel quickly and ready to pour, but fine control of the alloy composition was absent. The open hearth furnace allowed alloying elements to be mixed into the batch. It lost a lot of heat, and required low carbon feedstock.

Associated Open Hearth Furnace Question:Reason for which open hearth furnace for steel melting have almost died in foundry?

• Answer:Development of the oxygen converter and the electrical furnace. More economical, more flexible, result in extremely high productivity, and wide range of process applications. .

Associated Open Hearth Furnace Question:What is the process of iron being converted 2 steel by using a bessemer converter?
:And by using the open hearth furnace. They are two separate questions. Please help. I can’t find the answers on the internet anywhere.

• Answer:The Bessemer is basically a more thermodynamically efficient closed in version of the same process used by the open hearth, which lets heat escape on the theory that impurities somehow escape better along with it, which is nonsense. Oxides of iron are mixed with industrial coke, which is coal with all volatiles driven off by heat/evaporation usually under the furnace and burned as initial heating, leaving nearly pure carbon and ceramic substances, and the whole works is fed air under pressure, insufficient to combust the carbon, which forms superheated carbon monoxide. Oxygen is pulled out of the iron oxides in a classic Reduction/Oxidation Reaction as the carbon is further oxidized into CO2, leaving mostly elemental iron mixed with a small percentage of carbon. This is called steel. The ceramic chemicals float on top as slag. There is more to it than this abbreviated explanation, but this will do for starters. Regards, Larry.

Question
My lp furnace has started to make a strange noise when the
burners first come on.  It sounds like a loud hummm coming
from the burners.  It seems to go away when the blower starts,
or the sound of the blower covers it. It also seems to happen
only when outside temperature is below about 15F. I can make the
noise stop by throttling the flame down with the off/pilot/on
dial control on the gas valve.  Furnace seems to be working fine
other wise.  Regulator maybe going bad?  TIA

Answers
If the problem is only occurring when it is below 15f, it most likely is
low gas pressure in the tank. This will cause a wide open condition on
the regulator and gas valves, which I have heard anything from a hum to
a squeal. If you have an above ground tank there is really no good
answer other than to keep it full as possible. An in-ground tank should
not have as severe a problem, but if full and the problem persists, I
would have the high pressure regulator on the tank checked.

Associated Lp Furnace Question: I have a old travel trailer with a lp furnace. the pilot light gos out when the main burner try to start?

• Answer:Most travel trailer furnaces as well as mobile home furnaces have sealed combustion chambers. This means the burner draws it’s oxygen from the outside atmosphere, drawing none from inside the trailer. If the exhaust or the air intake is restricted or stopped up, you get what I call “candle in a jar effect”. Candle in a jar, put the lid on, when the oxygen is gone, the flame goes out. If the air intake is stopped up, it gets no oxygen, if the exhaust is stopped up, it fills up with CO2 and displaces the oxygen. Check both of these first. Another possibility could be gas supply. Make sure that there is no restriction of the gas flow. If a small amount is coming thru, it will allow the pilot to lite, but when the main burner ignites it may not be enough flow to keep it going. With the gas off, disco the line to the gas valve. Connect a union and a gas hose or another piece of tubing to it and run to the outside. Have some one turn the gas on and see if you get a steady flow. you should hear it. Notice if it starts and then greatly reduces. If it does, you have a restriction somewhere. Good luck.

Associated Lp Furnace Question: Does anybody know exactly how a LP gas furnace is supposed to work in a class C motor home?
I am trying to get my furnace to stop blowing cold air there is no pilot light or is there any place to light the furnace, i put in a new thermostat and someone said that the heat anticipator is out of adjustment the furnace never blows warm air it is just cold

• Answer:I seriously doubt that it is the heat anticipator needs adjustment. Most of those units made after the early 80’s are sealed combustion with direct spark or intermittent pilot ignition. Most of them have an ignition sequence that starts the blower motor and the draft induction motor at the same time. This means that the blower motor is running before your main burner is running (blowing cold air). I’m not sure from your question if it starts blowing warm air later, or if it is not blowing warm air at all. Do you get warm air eventually, or does it just blow cold? Edit: Ok, if it never blows warm, you’re going to need some serious trouble shooting. On the intermittent pilot models the most common problem is pilot orifice getting plugged. On these units a small electronic spark igniter lights a pilot light that only runs when there is a call for heat. The pilot orifice gets plugged and the flame sensor will not allow the main burner valve to open. On the direct ignition models, the most common problem is the flame sensor itself. Keep in mind, I said in most common problem; it could in fact be a number of other things. Problem with these units is that they are built so compact that they are a pain in the butt to work on, and for this reason most HVAC techs don’t want to touch them. Parts are very specific as well, so your best bet is to call around to Camper dealerships that have a good tech on the staff (very hard to find). As I said before these are sealed combustion units and you should really not tear into this unless you really know what you are doing. If you need help finding someone, feel free to email me with your location. I know a few good techs around the country that might be near your location.

Associated Lp Furnace Question: what could couse a lp gas furnace to go on and off to much?
right now it’s runs for about 1-2 minutes then shut off and the it will start back up in about 2-3 minutes. The flame is ok it just keeps stopping and going. When it shuts of sometimes it sounds like it’s creating a back draft. Please does anyone know why it’s doing this. I checked the Thermacouple and it seems to be ok. HELP Thanks

• Answer:Check your thermostat. It may need to be replaced or it could simply be off level. If it’s not level, the mercury switch attached to the coil will not work correctly. You can level it with a small torpedo level and a screw driver. It’s easier to try the simple stuff first. Also check your line from the tank to the house, it might have a slight kink in it. If that’s the case call the repair man to replace it.

Question
We’re moving our utilities (furnace, water heater, etc.) from the
utility room into the garage.
I did a “say what ?” when my wife mentioned that a heating
contractor
asked her if we thought of placing the forced air furnace in the
attic.
He said that the ducting would be easier to layout and therefore
cheaper.
He also said that the heat would be transferred to the attic space
when
the unit ran during the cold months thereby helping the house to
stay warm.
[BTW, we are eventually going to put in air-conditioning so we're
keeping it in mind when putting in the furnace.]
Now I haven’t called the guy and talked to him yet but I’m against
the idea because:
I’m not sure if its legit — I need to call the local building
dept.
We’re doing everything with permits.
The risk of a fire due to a defect or malfunction is probably
the same for the garage or the attic location but the consequences
are
greater for a unit in the attic than one behind the “1 hour”
firewall
in the garage. Even if it is legit, I’m afraid about the re-sale value of the
house.
If its is OK to put one in the attic, potential buyers may feel
otherwise.
Am I being unreasonable ?
Does anyone actually have a furnace located in the attic ? If yes,
then
what is your experience with owning it and selling the house ?

Answers
i have worked on plenty of furnaces that are located in the attic. i
am against it simply because it is a pain in the butt to work on.
generally, i recommend putting them in the attic only if there is no
other place put it. they make horizontal furnaces that can fit in
tight spaces like an attic or a crawlspace. again, they are harder to
work on.

if you are going to install an air conditioner, and you go with the
horizontal furnace, make sure that they place the furnace in a pan, so
that if the condensate an get backed up, it doesnt go onto the
ceiling, thus causing additional headaches.

my recommendation is to put it in the garage. (my opinion–you may
find many who are perfectly content with their horizontal furnace.)

Associated Horizontal Furnace Question: Anyone ever have a horizontal attic furnace?
Does it raise your heating bill? Does it cause structural damage from heat or moisture from snow thaw? Anything else I should know? Thanks.

• Answer:In direct answer to your questions: It does not raise your heating bill any more than a vertical furnace. It’s all the same engineering. One is just horizontal and the other vertical. It should not cause any structural damage to your home. These systems are normally hung from the roof trusses with steel straps so they don’t vibrate and transmit noise into the home. Really, it shouldn’t raise the temperature in your attic much, if any. The most important thing about any heating system is to be sure it’s plumbed properly and the electric service is run properly. Next, there should be no leaks in either the plenums (distribution boxes attached to the furnace) or the ductwork. Leaks will cause the system to run inefficiently and draw dust and untreated air into the home. If you’re considering a new home, you’ll get a guarantee on the system as well as the home. If you’re buying a resale, have the mechanical systems inspected by a licensed Home Inspector and read the report he/she provides. I’ve had multiple horizontal furnaces in homes I have owned. My present home has two system, both horizontal and both in the attic.

Associated Horizontal Furnace Question: How much should I be paying to buy and install a horizontal 90% efficiency, 80-100K BTU furnace in my attic?

Associated Horizontal Furnace Question: Need advice about home furnace?
About how much would it cost to have my broken furnace replaced. It is the horizontal type that sits in my attic. My house is 1400 sq ft… I’m just looking for a ballpark estimate, and if you know the cost breakdown for labor that would be great. It is a gas furnace. The quote I’ve received is in the $2500 to $3000 range, which appears on the high side. (I live in So. Calif.)

• Answer:When replacing a furnace the most important thing you need to remember is to get at least 3 estimates, and always compare Apples to Apples. Always request an estimate that contains a complete breakdown of parts, material and labor. With that being said you will need to have a basic understanding of what you are looking for when requesting an estimate from a HVAC contractor. It’s very hard to give a ballpark figure without knowing exactly what you would like to replace your current unit with. The cost of the furnaces can vary greatly based on the type of furnace it is. For example, an ultra high efficiency furnaces made by any particular manufacturer can cost hundreds of dollars more than a standard efficiency unit of the same BTU rating made by the same manufacturer. You should call a heating contractor explain your heating needs and request information on your replacement options. Take your time, do your research and you won’t get ripped off. Nor will you end up owning something you don’t need. With the unstable nature of energy supply and price the installation of high-efficiency furnaces should be a major consideration of anyone replacing a furnace. Studies have shown that homes where a standard efficacy furnace has been replaced with a 90+% efficient unit, can experience an average cost savings of 22% on their annual heating bill. HVAC contractors labor rates vary by area as well, but on average you can figure somewhere in the neighborhood of $50 to $80 an hour. All HVAC contractors should have the mechanical credentials that are required by your state and local municipality. Do not hesitate to inquire about contractors credentials, and should you receive a bid with suspiciously low labor rates definitely request a copy of the contractor’s credentials. I really have to question some of the prices being quoted here in some of the other answers $400 for a furnace really makes me wonder what you would be getting.

Associated Horizontal Furnace Question: Who makes the best geothermal furnace and why?
I am in the process of getting quotes for a horizontal, closed loop system and need to know which brands of systems are the most reliable and time tested. Each contractor seems to push different manufacturers. I will be using the system for hot water also. I will have no gas or oil backup.

• Answer:It depends on type of installation. Horizontal Ground Closed Loops, Vertical Ground Closed Loops, Pond Closed Loops The length of the loop depends upon a number of factors, including the type of loop configuration used; your home’s heating and air conditioning load; local soil conditions and landscaping; and the severity of your climate. Larger homes requiring more heating or air conditioning generally need larger loops than smaller homes. Homes in climates where temperatures are extreme also generally require larger loops. ~ The name Lennox is synonymous with heating and cooling equipment.

Associated Horizontal Furnace Question: How do I winterize my high efficiency furnace?
The brand is a Bryant horizontal.

• Answer:Shut off power,remove panel to access heat exchanger,vacuum out any & all debris,also look for any holes in the heat exchanger (if any are found don’t proceed,leave power off and don’t operate furnace & call for service)check wiring for any signs of loose or burned connections & correct.Put panels back,restore power,ensure thermostat is level,set to heat & raise temp above room temp.Measure the temp rise of the furnace(the difference of the air coming out of your vents(diffusers)and the air going into your filter)This should normally be between 40f & 70f. For instance if you have 70f air going into your furnace,you should have around 130f coming of of the heat exchanger.(60f temp rise) Lower the setting on thermostat and let the unit cycle off.(before it heats your home too much) Good luck

As I hnow,  There is a paper in MPT 1991 14(2) 36 about Fastmet.
In China, Two rotary hearth furnaces are used to produce DRI. One’s
diameter is 8m, the other is under construction.

Associated Hearth Furnace Question: What is the difference between the Bessemer converter and the open hearth furnace?
The subject is Mechanical Technology.And also list the disadvantages and advantages of the bessemer converter and open hearth furnace, PLEASE and THANK YOU. (im just being polite)

• Answer:The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. The process is carried on in a large ovoid steel container lined with clay or dolomite called the Bessemer converter. The capacity of a converter was from 8 to 30 tons of molten iron with a usual charge being around 15 tons. At the top of the converter is an opening, usually tilted to the side relative to the body of the vessel, through which the iron is introduced and the finished product removed. The bottom is perforated with a number of channels called tuyères through which air is forced into the converter. The converter is pivoted on trunnions so that it can be rotated to receive the charge, turned upright during conversion, and then rotated again for pouring out the molten steel at the end. A blast furnace is a type of metallurgical furnace used for smelting to produce metals, generally iron. In a blast furnace, fuel and ore are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the bottom of the chamber, so that the chemical reactions take place throughout the furnace as the material moves downward. The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace. Blast furnaces are to be contrasted with air furnaces (such as reverberatory furnaces), which were naturally aspirated, usually by the convection of hot gases in a chimney flue. According to this broad definition, bloomeries for iron, blowing houses for tin, and smelt mills for lead, would be classified as blast furnaces. However, the term has usually been limited to those used for smelting iron ore to produce pig iron, an intermediate material used in the production of commercial iron and steel.

Associated Hearth Furnace Question: What are the advantages and disadvantages of the Bessemer converter and the open hearth furnace?
The subject is Mechanical Technology.

• Answer:The Bessmer converter was for converting cast iron to steel by oxidizing the excess carbon. It produced the steel quickly and ready to pour, but fine control of the alloy composition was absent. The open hearth furnace allowed alloying elements to be mixed into the batch. It lost a lot of heat, and required low carbon feedstock.

Associated Hearth Furnace Question: Reason for which open hearth furnace for steel melting have almost died in foundry?

• Answer:Development of the oxygen converter and the electrical furnace. More economical, more flexible, result in extremely high productivity, and wide range of process applications. .

Associated Hearth Furnace Question: What is the process of iron being converted 2 steel by using a bessemer converter?
And by using the open hearth furnace. They are two separate questions. Please help. I can’t find the answers on the internet anywhere.

• Answer:The Bessemer is basically a more thermodynamically efficient closed in version of the same process used by the open hearth, which lets heat escape on the theory that impurities somehow escape better along with it, which is nonsense. Oxides of iron are mixed with industrial coke, which is coal with all volatiles driven off by heat/evaporation usually under the furnace and burned as initial heating, leaving nearly pure carbon and ceramic substances, and the whole works is fed air under pressure, insufficient to combust the carbon, which forms superheated carbon monoxide. Oxygen is pulled out of the iron oxides in a classic Reduction/Oxidation Reaction as the carbon is further oxidized into CO2, leaving mostly elemental iron mixed with a small percentage of carbon. This is called steel. The ceramic chemicals float on top as slag. There is more to it than this abbreviated explanation, but this will do for starters. Regards, Larry.

Associated Hearth Furnace Question: The Modern Blast Furnace – need information?
Need help on the modern blast furnace I have spent ages lookin for information on this on the internet and no luck so far. I would like to know: the material used to build furnace raw materials used in the furnace size of furnace hearth power source for the blasts of air main use for the iron produced thank you, any help will be much appreciated

• Answer:I assume you are looking more at a furnace for melting scrap iron as most large blast furnaces produce steel. The outer skin is normal steel (low to medium carbon) the inside is lined with ceramic, either a special cement like mixture or brick with a special mortar. The raw materials are either ore, scrap iron and limestone and other additivess. Steel alloys require exact amount of chrome, etc, depending on the properties required. Size of heath depends on size of furnace and power source. Air is from large volume air punps, usually electric. Iron is mainly used for applications where low loadings are expected eg garden furniture, decorative castings.

Associated Hearth Furnace Question: The type of melting furnace…?
The type of melting furnace that produces the largest portion of the steel used for casting is the: 1. open-hearth furnace 2. bessemer converter 3. pot furnace 4. electric arc furnace

Associated Hearth Furnace Question: what’s the difference between iron and steel?
i know that steel is an alloy of iron but i really dont get it…… i know that in open-hearth furnace, steel is made from iron ore and scrap iron..but open-hearth furnace is used to remove the impurities of the ore.. so does removing impurities from the iron ore make steel?????????????? help plz.. i am confused..

• Answer:You’re already correct. The iron that contains less than 2% of carbon is called steel whereas which contain more than 2% of carbon is known as pig iron. The following article may be of some help: http://www.differencebetween.net/object/difference-between-iron-and-steel/

Fact is that people still buy lots of lower-efficiency stuff. They *should*
buy high-efficiency furnaces and efficient cars, but there is still a big
market for SUVs and lower-efficiency furnaces. If the furnace is relatively
new and in good condition, it could be a good deal.
Associated Gas Furnace Carrier Question:Help please. Why Carrier gas furnace 9200 does not ignite after inducer starts?
My Carrier gas furnace 9200 shuts down after 20-30 seconds after its inducer starts, ie, the burners do not lite. But if I take off the burner cover (about 4″x10″ with a glass whole, inside the main cover), the burners lite and the furnace seems to work fine. Any idea why? Thank you very much.

• Answer:If you are handy with an VOM meter and electronics, you can fix it your self. Everything is clearly marked lead by lead and connection by connection. This is a simple circuit not a TV set, so its not rocket science one bit. If not qualified call a tech. On the backside of the blower door is a schematic of the entire circuit. There are about 7 safety switches that need to be checked for “Open” or “closed” as shown on the schematic. Check those out entirely. You cannot check a flame sensor with a meter, unless you have a special HVAC tool to do that with, and even then, you cannot be real sure. On your Carrier furnace, your flame sensor is on the far left at burner level, so ignition should indeed take place if that is even defective and then an immediate shut down, Its about a 2 second delay in there. So that problem with this sensor is pretty much ruled out based on what you are saying in your statement that there is no gas flow. . So left also is High Limit, That isnt it, because the Carrier will run the blower in Default constantly if the high limit safety is tripped. The most problematic and sounds like in your case, it is the pressure switch located near the exhauster blower. Its a bellows type of switch on there and sometimes those stick a bit. Take an ohm meter on the VOM and see if that is it. Read the schematic. If it is, take and manual trip it a couple times to free it. If that doesnt work Replace it. The entire replacement of all safety switches is about $100 on a Carrier. The main control is about $85. One can buy parts on line overnight shipment, www.furnaceparts. com. On there is a complete list of your Carrier model’s parts so no need to go hunting around for the part #.

Associated Gas Furnace Carrier Question:One of the two burner orifices is not lit up for my Carrier gas furnace. The unit is about 10 years old. Any i?
One of the two burner orifices is not lit up for my Carrier gas furnace. The unit is about 10 years old. The pilot has flame on it though.

• Answer:Gas is usually a little dirty and can clog a burner orifice. Try poking something into the orifice the clear it out. Not a tooth pick because it can break off inside then really plug it up. but try using a very small drill bit by hand and poke it in there to clear the orifice. A small paper clip may also be thin enough to fit into the orifice hole. Welders use wire pipe cleaner type tools that are almost like little round files that have little burrs on them to clear out debris from a torch tip. But a small enough drill bit works just as well. Just remember to do it by hand.

Associated Gas Furnace Carrier Question:Where to find Carrier gas furnace manual Model # VR800A1020?
a website to a pdf would suffice! Sure would save on a service call just to light the pilot light correctly without blowing anything or anyone up.

• Answer:This is an unusual number for a Carrier furnace. The thing is Honeywell makes a gas valve with that number. Are you sure you’re getting the number directly off the furnace? The model number for the furnace would be on a sticker off to the side or down underneath the gas valve.

Associated Gas Furnace Carrier Question:Can anyone help with Carrier gas furnace 58MVP problem?

After motor was replaced, furnace worked but after a half hour, furnace would not light and code 42 flashed again. After shut off for 2 hours, furnace worked for a half hour again then would not work. Any suggestions ?

• Answer:Check the intake also. Flush the trap(that’s the white PVC fitting located in the shelf that separates the blower compartment). Then flush your drain hose. Be sure to also check the PVC intake and exhaust terminations outside.

Associated Gas Furnace Carrier Question:carrier gas furnace?
i have a carrier gas furnace model number 58bd-125-2a. I can not find any info on it and it will not turn on. The fan will turn on if i put it in the on posistion but i can not get the burners to ignite. The pilot light is lit up just fine. I would appreciate any help given. Thanks

• Answer:Well it actually sounds like the problem is it the thermostat. Put the stat in heat and the fan in auto go to your furnace and remover the front cover. You should have 24 V from the common lead Blk to the white lead. White is the heat, yell is cooling and green is fan. Black and red are positive and common voltage. If your stat is bad it is an easy fix. Home depot sells tham. All you need is a volt meter to check this.

Associated Gas Furnace Carrier Question:I have a Carrier furnace. The gas valve works intermittently?
A 5 year old Carrier furnace, with HSI: The gas valve has worked intermittently for the last year. I would come out to the garage, cycle power to the furnace, and the unit would then work (sometimes) I’ve done the following: 1. I tested the connection from the PCB to the valve, both green two wire connection and the blue. No change. 2. The large solenoid clicks when the relay turns the valve on, but the small relay doesn’t seem to be working. 3. It tries three or four times, then locks out for three hours. 4. I’ve checked the PCB and no obvious heat or burn marks on the board. 5. I’ve made sure I have a good ground (I ran a jumper to a nearby water line to make sure) 6. The fuse on the PCB is fine. 7. The cycle is normal, (power-up, wait a few secs, the main blower blows for 2 min, the purge motor comes on for 10-15 sec, I hear the hsi relay , the hsi glows, the gas valve relay and the large solenoid clicks. Any option but to replace the gas valve?

• Answer:tighten all wire connections, check for any oxidizing on wires or terminals(boards). on valves put a screwdriver on top to make sure valve is working, try to pull screwdriver up off top it should have magnetism feel to it. if these are ok you will need to replace valve.

Associated Gas Furnace Carrier Question:Home furnace recommendation, Carrier or Trane?
We had 2 heating companies come out. These models were possibilities they mentioned, at various prices. Which is best furnace for the money and quality? TRANE XL80, Carrier Infinity 96 Gas Furnace, Carrier Infinity 80 Gas Furnace, or the Carrier Comfort 80 Gas Furnace? We will choose one of these and need insight. Thanks!

• Answer:The most important factor is one you have not mentioned. The unit is only going to be a good as the company and installer you choose. The most important day of your new furnace’s life is the day it’s installed. Most major companies have similar warranty and service provisions and many offer extended warranties and service contracts at additional cost. The cost of all is negotiable. Bargain well. Check the reputation of the companies you are considering with the Better Business Bureau (www.cityname.bbb.org) and ask for references you can contact directly. As for a specific brand, I’d balance the cost versus the reputation of the dealer, etc.
