Cold Air Coming From Gas Fireplace

We recently bought a 1996 house which has a majestic gas fireplace.

Cold air coming from gas fireplace.

When you close the flue you re essentially plugging the chimney with a metal flap. Install an energy efficient damper like a top mounting damper to seal off the flue completely when not in use note. The previous owner had a contractor put in a gas insert. You will stop the cold drafty air in the winter and keep warm humid air from coming in during the summer months.

Then there is a constant flow of cold air coming out of the vents above and below mostly below the glass. If the fireplace has a rear vent make sure it is sealed off when not in use. Pilot light is lit. The air comes in through the large unsealed hole that is left from the pipe going through.

A damper is a metal flap in your chimney that blocks cold air from coming in and warm air from escaping. Use our flue coverto stop the outside air from coming in through the flue. Putting a bag or plastic over the box outside does nothing. We have been keeping a blanket shoved up in front of the bottom vent.

Chances are before you had gas logs installed your fireplace was a wood burning fireplace. The only reason why your vented gas fireplace is drafty is because of the gas logs being installed. This air is direct to the surrounding area behind the fireplace and comes out through any vent usually the lower grill making the floor icey cold. Cold air coming in from bottom underneath of gas fireplace insert we bought a house earlier this year that has a family room addition with a brick fireplace.

The only place the cold air is coming in from is from the vent on the back that opens up directly to the outside of the house. Use our magnetic fireplace vent coverto stop the inner cold air circulation from the vents.
