Pilot won't light - natural gas or propane. check for a spider web in the burner tube. check no dust in burner tube. check surface igniter is lit. if pilot lights check flame detector - may be a millivolt generator - it is a small capillary with a copper tip in flame path. no fire will keep the pilot valve closed. replace the generator.

My empire wall furnace does not ignite. It has gas flowing because the pilot is light, i have changed the thermostat and wired it two different ways in case I reversed them. What is next? Could it be the...

It could be several things: Is the Control Knob turned from Pilot to ON? If that is the case, wait a few minutes after turning it to ON. That will allow the Thermopile to heat up sufficiently. Be sure the flame is touching the Thermopile. If everything looks correct turn up your Thermostat to higher than the ambient room temperature and see if the burners light. Remember to turn your Wall Thermostat down to the lowest temperature setting before turning the knob from Pilot to ON.

FYI - That Wall Furnace does not have a Thermocouple. It uses a Thermopile instead to generate millivolts of electricity to open the gas valve and maintain the pilot flame.

If it is the Thermopile, you can order it directly from Empire Comfort Systems, as well as download your Owners Manual at
