Abstract

A fireplace form comprising a firebox having an open front, a back wall, and a pair of side walls extending from the back toward the open front. The back and side walls which at least partially converge in upward direction form a main flue outlet generally at the top of the firebox for communication with a chimney flue. The firebox has at least one aperture therein in its back wall intermediate the bottom of the firebox and the main flue outlet. The fireplace form has ducts on the back side of the firebox in communication with these apertures and the chimney flue, these apertures and ducts constituting auxiliary flues for at least partially ducting away smoke and other products of combustion from the firebox. An outer housing surrounds the firebox and defines a chamber between the firebox and the housing for circulating fresh air over the back side of the firebox and over the ducts so as to be heated for discharge of heated air into a room.
