SOURCE: I have a Dayton gas heater Model 3E225

Does the main blower fan kick on? Also, if the heater is vented outside via a flue pipe, there may be a small (about 3 or 4 inches in diameter) vent fan that kicks on to ensure the exhaust fumes are evacuated through the flue pipe. If there's a problem with that fan, the burner won't light either.

Check with Ebay seller s.a.w.inc for available thermocouples. If that doesn't solve the problem the valve unit will likely need replaced.

SOURCE: pilot light goes out when turning on the thermostat

Check your thermocoupling to make sure that it is sensing flame. You can tell if it is good or bad by the white on the tip of the flame sensor. The other problem would be a blocked or closed flue pipe. Make sure that the cap is not smashed down on the pipe on your roof

SOURCE: Dayton Furnace - Pilot Light Goes Out but Fan keeps running?

Pilot lighted furnaces have a thermocouple made from disasimilar metals that when heated create electricity to actuate a relay that alows the gas to flow to the furnace.

When the thermocouple gets coated with carbon from the pilot lights constant burning it acts as an insulator and keeps the thermocouple from getting enough heat to generate electricity, a very good safety factor.

What you have to do is locate the thermocouple it should be located over the pilot light, you will see a gray substance around the thermocouple it will be hard like cement, take a knife and scrape away as much of the gray material as possible then sand the themocouple with a medium sandpaper until it shines, use one of you wifes emery boards, this should solve your problem.

SOURCE: pilot light not working in gas heater

That probe that sits in the pilot flame is at fault. Remove and replace. Inexpensive fix. Make sure probe is in the tip of the pilot flame. If it does not stay hot enough, it will shut off the gas.

How to light pilot on Dayton furnace and then start furnace


If this is a standing pilot system, turn the gas valve to pilot position. push in the knob & hold while lighting pilot...keeping holding knob down for a minute... this will pick & hold the gas valve. Let go of the knob & see if the pilot stays lit, if it does, then turn the knob to on position & the furnace should start if there is a call for heat from the thermostat

Have a dayton 3F405D propane greenhouse heater don't know where to light the pilot light.


Find where the gas line connects to the gas valve on the back of the heater, from the gas valve, follow a small aluminum tube going into the back of the heater. There may be a removable door to access the pilot assembly. If there is no aluminum tube, the unit has electronic ignition and no pilot lite. Turn the gas knob to off, then to pilot. Hold the gas valve in and with a long match or gas grill lighter, light the pilot. Continue to hold the knob in for about 30 seconds. After that, release the knob and check to make sure the pilot stays lit. If so, rotate the knob to ON. The thermostat will kick the burners on.

Dayton 3e239e looking for operation manual


Normally you turn the gas valve to the pilot position, light the pilot, hold down the gas valve knob for 30-40 seconds and release. If the pilot will not stay lit replace the thermocouple. These are available ay Home Depot.
