Cold air leaks with zero-clearance fireplaces
Do zero-clearance fireplaces, with or without outside air kits, generally leak cold air into the room when not in use?
We had a CFM Sequoia installed last October 2004 with an outside air kit and the room was frigid when not in use. While disconnecting the outside air duct improved the cold air problem, it did not solve it. I believe there is an airleak from the chimney stack that is cooling down the unit behind the wall, but I am having a hard time convincing the installers or CFM to investigate this. Because I am struggling with other issues with the Sequoia (the glass completely smokes up during each burn), I am tempted to insist on a refund and then replace it with another brand. However, based on reading through this forum, it doesn't look like there is a clear winner in this category of wood-burning, EPA, zero clearance fireplaces...or is there?
