Perform a visual inspection for flames. If the pilot light is out, follow the instructions in the owner's manual to relight it. If the pilot light goes out again after relighting it, check the vent cap to ensure it is secured properly. A heavy draft can blow out the pilot light.

Clean the gas fireplace interior as well as the flue, according to the owner's manual.
