ABSTRACT:
A prebuilt fireplace construction for installation in a building structure. The construction includes a firebox having an open forward side and an outlet for combustion gases and a housing at least partially surrounding the firebox with the combustion gas outlet extending through the top of the housing. A rotatable damper is disposed within the housing and is controlled externally by a rotatable shaft extending forwardly through the housing which is engaged by an external actuator operable from the front of the fireplace. An inlet conduit for combustion air is built into the housing for the fireplace beneath the level of the firebox for supply of combustion air to the firebox in the event doors are later added to close off the firebox.
