Fireplace construction

Patent ·
OSTI ID:5680370
A prebuilt fireplace construction for installation in a building structure, such as a mobile home, is presented. The construction includes a firebox having an open side and a combustion gas outlet adapted to be placed in fluid communication with a flue. A transparent door is provided for substantially sealing the open side and a housing at least partially surrounds the firebox in close proximity thereto to define an air space therebetween. The air space has a relatively low inlet and a relatively high outlet. A conduit isolated from the air space is provided and is adapted to be placed in fluid communication with a source of outside air. The conduit opens into the firebox to provide combustion air. A baffle is interposed between the opening of the conduit into the firebox and the combustion area thereof.
