How to Make a Gas Fireplace More Efficient

Updated February 21, 2017

The ability to return home on a cold day and make a warm fire just by flipping a switch makes gas fireplaces desirable. There is no need to haul wood or remove piles of ashes. Some gas fireplaces have heat exchangers that provide a warm fire even if your electricity goes out. With regular maintenance, your fireplace will be more efficient and last longer.

Arrange for your gas fireplace to be professionally cleaned and inspected every year. An accumulation of dirt, insects, and debris will affect the performance and appearance of your fireplace.

Clean the glass on your gas fireplace after the first 4 to 6 hours of use to prevent deposits from baking onto the glass. After the initial cleaning, clean the glass at least once each year with an ammonia-free cleaner. Ammonia can leave a haze that can be baked onto glass. Mix a solution of half white vinegar and half water to clean class. Buff the glass dry using a clean cloth.

Keep the fireplace logs positioned correctly. The logs and gas burner operate together as a unit.

Clean your gas logs by carefully removing them, placing them in a box, then taking the logs outside to vacuum clean. You can also clean the logs with a soft brush.

Make certain you have a blue pilot flame in your gas fireplace. Keep the gas pilot light clean by turning the gas shutoff valve to the "Off" position, then removing the metal shield from the pilot light. You can use a sewing needle to remove the build-up of debris from the opening of the pilot. Blow away all loose debris, then turn the gas shutoff valve to the "On" position.


Never burn wood or any other materials in your gas fireplace--this creates a fire hazard. Keep children away from the glass doors of your gas fireplace to avoid burns. The glass can reach high temperatures. Have your fireplace serviced if you see a yellow pilot flame. A yellow flame means too much air may be entering the burner instead of the proper mixture of gas and air.
