Claim Text:
1. A gas fireplace assembly comprising: a sealed combustion chamber having a door; a first burner disposed within said combustion chamber; an air inlet; a first air conduit in fluid communication with said air inlet and in sufficient proximity to said sealed combustion chamber that air within said first air conduit can be warmed by said sealed combustion chamber; a combustion air conduit in fluid communication with said sealed combustion chamber and configured to route combustion air to said sealed combustion chamber; a combustion air exhaust having an opening in fluid communication with said sealed combustion chamber and configured to remove exhaust air from said sealed combustion chamber; a cover configured to removably cover said opening of said combustion air exhaust, said cover operably connected to said door, such that opening said door causes the cover to move to a closed position covering said opening and closing said door causes said cover to move to an open position uncovering said opening; wherein said cover and said door are configured to convert said gas fireplace assembly from a first configuration to a second configuration; and wherein said first configuration vents combustion exhaust exclusively through said combustion air exhaust to an exterior of a structure and said second configuration vents combustion exhaust exclusively to an interior of a structure.
