Question about Empire DV-35 Heater

Open Question

I have a Empire DV-35-2SG Pilot lights but burner does not come on. I replaced the thermopile still does not light. What voltage should I measure at the gas valve where thermopile is connected? How can I tell if the thermostat may have failed?

Check your gas pressure, You could have a gas valve problem or you could have a restriction in the air intake.

SOURCE: empire wall heater with wall vent pilot light

It sounds like the gas valve is dropping out. Make sure the system is venting the exhaust(no restrictions). Then make sure all your wiring connections in the unit are tight. In a millivolt system if all wiring connections aren't tight and clean your circuit will drop in millivolts and the gas valve will drop out. The gas valve requires a certain millivolt to stay open. I hope I was of some assistance!! Good luck!!

Hi,
The pilot ofifice probably has a bit of dirt in it...to get it out you will need to take the pilot apart and clean it out...this can be fairly difficult on those heaters and getting it back together can be a pain...pay attention as you take it apart...blow our the tip with canned air like you would use to clean your keyboard...
Then reassemble...
Sometimes the "hood" or the cover over the flame will bend up over time and you will also have to bend it down a bit to get the pilot flame onto the thermocouple...make sure the thermocouple is also pushed all the way up in the holder...

Empire dv-25. Pilot lights fine, good blue flame. Burner rail won't light or stay lit - sometimes it starts to catch. Orifice was removed and was clean - no debris. Not sure where to look next? T.Y.


Do you have an electrical meter that measures millivolts?This sounds like a millivolt system. The pilot orfice and pilot burner need to be clean so they are producing a hot flame, hitting the pilot generator to create enough millivoltage to open the main valve coil. If you know how to jumper the thermostat circuit try it, Millivolt systems will give you problems if there are loose connections or to much resistance through a switch. Again, there could be some type of safety switch that is wired into the thermostat circuit to prevent the heater from coming on if it isn't safe. Call a pro if its not obvious

Napolean fireplace burner wont light


If your pilot is running fine, but your burner will not light:
  • You may have a bad thermopile.
  • There may be blockage in the burner orifice.
You can test the voltage of the thermopile per your owner's manual (replace if necessary).
You can clean out the burner orifice with some compressed air.

Hello i have a J5 lincat fryer and the pilot stays alight but the burners won't connect (light) have replaced the thermostat and the thermo couple but still no joy any ideas on this not sure what to do...


Check if there is 500 to 750 millivolts across the thermopile wires; thermopile generates 500 to 750 millivolts if properly heated to energize pilot and main valve solenoids of the gas valve for pilot and main burner operation. If the voltage across the thermopile is good and all wiring connections are ok, I think you have to replace the gas valve.
Regards.

Poilt is very week and will not open gas valve


The reason the control valve is opening slowly is the the Thermopile needs to be replaced. The Thermopile generates millivolts of electricity from the heat of the pilot flame, which then opens the gas valve when heat is called for. Also, check the pilot flame to make sure it's engulfing the thermopile. If it's not the pilot needs to be cleaned.

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 www.empirecomfort.com

Soupydf1@netzero.com My Empire DV-210-6sg, the pilot lights and I can turn on the unit, but it will not sense the themostat to heat the room. themostat tested fine. what is wrong


There is another sensor called a thermopile or pile generator that most likely needs replacing. Look for two wires connected to the gas valve that has a metal strip wound around the outside of the wire. This will go to the pilot assembly and controls the main burner.

Pilot will light, burner will not light.


check all limit switches to see if they can be reset if so reset it ,if problem reoccurs wich limit is going out ? make sure all wires are connected well to your gas valve , use a low voltage tester to make sure your firing circuit is operating properly , if you have a thermocouple it may not have enough juice left to open your gas valve
