ABSTRACT:
A fireplace system comprising a hollow base pan and a shroud supported on the base pan and defining a combustion air chamber of inverted U-shaped configuration having open lower ends communicating with the interior of said hollow base pan. The shroud includes holes which open from the combustion air chamber into a central, front fireplace opening. An air plenum chamber is supported on the base pan adjacent the shroud and includes a firewall which defines a firebox, and a spaced wall which defines with the firewall and with the stack extending upwardly from the firebox, an air plenum space. A damper is located at an elevated location in the stack and includes an operator projecting downwardly to an accessible location at the top and forward side of the firebox. An insulation zone surrounds the air plenum chamber. A pair of firebox doors are movably mounted on the base pan, and a pair of door receiving channels are mounted on opposite sides of the air plenum chamber outside the insulation zone for receiving the doors in a storage status when they are not in use.
