Gas Fireplace Shuts Off On Its Own

I found a faded set of instructions and was able to light the fireplace.

Gas fireplace shuts off on its own.

Wasn t sure what to make of it so i shut it off. Ask your own hvac question. If the millivolt generator is old and weak or if the pilot flame is weak and wavering the main burner will go on and off. When i remove the logs it operates longer for about two hours before it shuts down.

To start the flame you need to press the trigger that is on the lighter. So if the fireplace was on already and you disconnect the main power i would expect the fire to stay on. It is about the size of an aa battery and is wired to the switch and gas valve. Take the logs out make sure you have the manual to put them back correctly.

The butane lighter is located near the center of the gas logs. Some gas fireplaces with electric start have a thermopile that generates enough electricity to keep the valve open even if you disconnect the mains electricity. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. The fire produced by the pilot should be sky blue in the middle and dark blue in the outer flame rather than a flame tinged with yellow.

Gas fireplace shuts off and pilot goes out after that you need to insert the butane lighter into the gas tube. Answered in 46 minutes by. The cowebs and dust burn off during the winter when you run it all the time and clog up the works during the spring and summer. Get a can of spray air or duster and spray in the back.

However starting by itself is not a good thing. Its around 18 years old. This in turn makes the gas valve shut off. Often a gas fireplace has a millivolt generator which is in the path of the pilot flame.

The thermocouple is a small device that generates electricity from heat they are used in gas furnaces and such to shut off the gas in case the pilot goes out so gas doesn t continue to flow and fill the room. It stayed up for 30 minutes and then died on its own. I have a gas fireplace natural gas that shuts itself off the pilot too after it operates for about an hour. There is an electrical switch on the wall.
