Moss, R G

A prebuilt fireplace construction for installation in a living space includes a housing, a firebox within the housing with an open forward side adapted to be sealed by glass doors, an outlet for combustion gases, an inlet for combustion air and has a base structure supporting the housing through which an inlet duct for combustion air extends. One end of the combustion air duct is connected to the combustion air inlet. The other end of the duct may connect to an optionally used air intake conduit so that exterior air may be delivered to the combustion air inlet, or receive air from a room interior which is drawn into the firebox through the base structure. A damper within the duct permits adjustment of external air flow into the firebox from either source and can be positioned to close the combustion air duct to prevent drafts when the fireplace is not in use.
