ABSTRACT:
A direct vent gas fireplace has a combustion air duct extending down the back wall, between the housing back wall and the fireplace back wall. It 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. The top of the unit is oriented at an angle less than 45.degree., preferably 23.2.degree. to horizontal so that the exhaust and vent pipes can be arranged in a top vent or a back vent arrangement without the pipes projecting beyond the back of the fireplace unit in the top vent arrangement.
