Gas Fireplace Shuts Off On Its Own

Under the fireplace there is a mains gas valve a pilot and an on off button.

Gas fireplace shuts off on its own.

Its around 18 years old. There is an electrical switch on the wall. I have a gas fireplace natural gas that shuts itself off the pilot too after it operates for about an hour. It is about the size of an aa battery and is wired to the switch and gas valve.

So if the fireplace was on already and you disconnect the main power i would expect the fire to stay on. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. It stayed up for 30 minutes and then died on its own. To ensure complete satisfaction of your heat glo fireplace we ve put together an extensive list of common questions to provide you with the information you need to guarantee proper and safe product operation at all times.

The butane lighter is located near the center of the gas logs. 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. 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. Ask your own hvac question.

Wasn t sure what to make of it so i shut it off. To start the flame you need to press the trigger that is on the lighter. I found a faded set of instructions and was able to light the fireplace. This in turn makes the gas valve shut off.

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. Gas fireplace shuts off and pilot goes out after that you need to insert the butane lighter into the gas tube. When i remove the logs it operates longer for about two hours before it shuts down. Often a gas fireplace has a millivolt generator which is in the path of the pilot flame.

Get a can of spray air or duster and spray in the back. Take the logs out make sure you have the manual to put them back correctly. However starting by itself is not a good thing. The fireplace gets full of cobwebs.

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.
