Cold air coming from gas fireplace.

You will stop the cold drafty air in the winter and keep warm humid air from coming in during the summer months. Chances are before you had gas logs installed your fireplace was a wood burning fireplace. 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. We recently bought a 1996 house which has a majestic gas fireplace.

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. Then there is a constant flow of cold air coming out of the vents above and below mostly below the glass. 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. If the fireplace has a rear vent make sure it is sealed off when not in use.

We have been keeping a blanket shoved up in front of the bottom vent. Use our flue coverto stop the outside air from coming in through the flue. The previous owner had a contractor put in a gas insert. 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.

However with vented gas logs cold drafts are quite common. Install an energy efficient damper like a top mounting damper to seal off the flue completely when not in use note. When you close the flue you re essentially plugging the chimney with a metal flap. Use our magnetic fireplace vent coverto stop the inner cold air circulation from the vents.

These are not recommended on gas log sets. The air comes in through the large unsealed hole that is left from the pipe going through.
