Cold Air Under Gas Fireplace

I have a gas fireplace that is blowing cold air into the room.

Cold air under gas fireplace.

You will stop the cold drafty air in the winter and keep warm humid air from coming in during the summer months. A damper is a metal flap in your chimney that blocks cold air from coming in and warm air from escaping. Even the heat fan that kicks in is located above the insert not below and there is no cold draft coming from the fan. The second person told me it was a normal part of the gas venting air flow.

We recently bought a 1996 house which has a majestic gas fireplace. The airflow in the control area under the insert doesn t seem to be part of the gas system. There is no trouble shooting suggestion for this problem. It seems that the gas insert s enclosure bottom must sit off of the bottom of the fireplace opening by about an inch.

Use our flue cover to stop the outside air from coming in through the flue. From the outside there is a fresh air intake on the chimney and there is a metal chimney exiting the top of the old stucco chimney. I am the original owner of the house and looked through the manual. After inspecting i realize that the reason this room is always colder than the rest of the house is because there is a ton of cold air coming in underneath the gas fireplace insert.

In the winter alberta we get huge drafts coming in the grills of our gas fireplace insert. If you have the damper closed but cold air still sweeps across the room it s very likely that your damper is worn cracked warped or generally degraded. When you close the flue you re essentially plugging the chimney with a metal flap.
