Ward Heater Company M0021

I have a floor heater, that is pretty old, maybe 50 years or so. I can't read the Model Number. The pilot stay lit, but when I adjust the thermostat for heat, nothing happens. The burner doesn't click on. It did work the last time it was cold, about six months ago. The gas company says it may be the blower. Most of the unit is under the house, it is a pretty deep unit.

Thanks for your help.

These old units have a simple gas valve and a separate regulator. Your best bet may be to replace the gas valve to something more modern. Trouble shooting this most likely be a waste of time, as parts probably aren't available, other than the thermostat. by-pass it, (connect the 2 wires together) and see if it comes on. The blower shouldn't stop the burner to come on. Sounds like the gas company doesn't want to crawl under there to light it.

Hello i have a williams wall Furnace model#25-35-50. I need to know if its a base board heat and also if you could tell me which wires are which. 1 red and 1 white

What you have is a Direct Vent, Gas WALL Heater. It is normally mounted about 6" off the floor on an exterior wall (since it has to be direct vented out). Not sure what the red and white wires are for, but suspect it's for the optional thermostatically controlled blower connection.

In any event, to help you install this heater properly, I have included a link to the Owner/Installation Manual, which should provide all the information you need to complete the installation correctly.

You can download and print the manual for future reference.

Have a wall heater thats wont stay lit think i need to change the thermal coupler. what do you think

Check and make sure the pilot flame is hitting the thermocoupler.Flame must touch thermocoupler, if the flame is not touching it, you may have to remove and clean pilot orfice to make flame stronger. check this before replacing thermocoupler, good luck.

GWN10T pilot blows itself out

You must clean the pilot regularly to ensure it burns properly. Use a small can of air for cleaning computers and blow air through the pilot to remove dust and small particles that accumulate in the pilot barrel. Use several burst being that it is 2 years old and has not been blown out. THe manual references cleaning the pilot in the maintenance section.

Torpedo heater wont stay lit.

Do you have the serial number or the manufacture date? There are some design changes and I would need to know the year of manufacture to assist accurately. Usually it is a relay or the thermocouple connection that will affect the unit staying lit.

Floor furnace

That is the control for the main gas valve. These old ones have a gas valve separate from the pilot. Also the regulator is separate unit. You have to turn these controls with a long rod, right?
