A direct vent gas fireplace has a combustion air supply duct extending down the back wall, on the outside of the housing back wall. It is connected to the firebox by a duct assembly with a flange that connects to the housing and two ducts that connect to the firebox. The supply duct is located laterally between two cooling air ducts that lead from the cool air zones at the bottom outer corners of the housing to a cooling air plenum inside the top of the housing. Inside the cooling air plenum and the cooling air ducts are a room air plenum and room air circulating space for the circulation of room air to be heated. This provides a compact construction with adequate wall cooling without the need for additional thermal insulation.
