Gas log will not stay lit for more than 5 minutes

Gas log lights correctly then shortly will shut down, pilot and all. You can relight immediately, and will run for a few more minutes then shut off again.

After you relight have you tried to leave the gas valve on pilot for 10 to 15 minutes so the themolpile warms up enough to send mil-volt signal. you also have a thermocouple that senses flam so if the flame is not hitting that just wright it will shut off. Is this fire place ran off a thermostat or a on off switch. If you are running off a thermostat then i would try to find on/off switch and try that. You might have to change pilot assembly out.If you do this and don't have manual i would take a picture of the log set up so you put it back together. Make sure all connections are tight when you go back together

Sounds like the gas regulator has failed.

There will be sufficient gas flow to light the pilot and get a flame prove, then the main burner lights, you will probably see the pilot flame reduce somewhat, and no longer fully surround the flame prove sensor.

When the unit is relighted, the complete sequence starts all over again.

Have the gas regulator checked and adjusted (if adjustable) or replaced by a qualified technician.

Lights but turns off in about a minute


It might have a built in thermostat that will light the heater when room temp falls below a certain temp. It should then relight and warm things back up. As long as the pilot stays lit it should work just fine.

Under the gas valve is a removable panel. On models of that era there should also be a second panel behind the first. remove both.

the pilot light should be clearly visible.

If no pilot, turn the gas valve to OFF. wait 60 seconds. locate the tubes from the gas valve to the pilot location. turn the valve to pilot, and with a long match or grill lighter lit, place flame at the pilot location and press down on the pilot button beside the main valve.

pilot should light. If not shut off the gas and call a technician. If yes, hold the pilot button for 60 seconds, then slowly release. Pilot should stay lit. If not, shut off gas and replace thermocouple, start relight sequence over. If pilot stays lit, replace inner cover and adjust temp to 120 deg. If heater fires up, replace outer cover. Done.

If heater does not light, replace gas valve or entire unit. Water heaters have a limited life expectancy, and if my recollection is correct your unit is 10yrs past warranty.

Pilot light wont stay lit on gas logs


If the pilot lite comes on, but will not stay on after it has had enough time to heat the thermocouple, you got a bad or the wrong thermocouple. It does take some time to heat that thermocouple.

Pilot won't stay on


Burners don't have anything to do with the problem of pilot not lighting. Is the problem that flame will not 'stay' lit? Or you can't even get a flame to ignite? If former: possible bad pilot generator or bad gas valve. If latter, possible bad gas valve or no fuel to ignite.

Pilot light keeps going out


pilot light keeps going out! more then likely its the thermal coupling doing this. if bad it shut all gas to heater for a safety measure. just shut power off, then turn gas off and replace it. then you should be ready to go. to relight heater hold down on gas vavle knob in the pilot position, hold down and light it at the coupling where gas comes out. when it is lit, continue to hold down for 60 seconds. release knob very slow. then if its lit, turn to the run position. if flme goes out, wait at least 5 minutes to expel the gas fumes and turn to pilot and try again. good-day !

The gas had been turned off. how do I relight the pilot?


Shut gas valve off and let it air out. You can see the pilot with the little rod on it. Turn valve to pilot position and light a lighter to light the pilot. Hold the valve for a minute. If it stays lit, then turn valve fully to the ON position.

Pilot light won't light on ventless fireplace


Ventless Gas logs, Vanguard, VS30PR. Propane gas
Pilot light stays lit various times, sometimes for several days then other times for a few minutes. Lights best when temp outside is below freezing. Pilot flame appears to receive too much air. How do you adjust the pilot flame? Is this done using two screws marked A & E? Do you have suggestions?
Thanks,
Ed

Imperial fryer IFS-40


I had a very simular problem. My fryer would do exactly as you described, but sometimes the pilot light would stay on until the burners tried to re-ignite and then it would go out.
I finally had to call the gas company. They took the pilot light apart and cleaned it. The fryer works perfect now.
Hope this helps!
