ABSTRACT:
An improved fireplace unit adapted to fit flush within the wall of a dwelling is disclosed. The fireplace unit comprises duct means for ducting cooling air entirely around the inner wall of the unit and especially around the front lateral edges and top, whereby flammable building materials can be brought into close juxtaposition with the unit without substantial danger of fire. Plural ducts are provided for cooling the rear wall of the unit, having inlets at the bottom rear of the fireplace unit, extending upwardly along the rear wall of the unit, and forwardly around the chimney, further cooling this area. The top wall of the unit comprises an integral support member and thermal break which allows the unit to support a conventional chimney without further support structure and provides a substantial thermal break between the chimney and the front wall of the unit. In a preferred embodiment, the fireplace unit according to the invention accepts an inner fireplace member which can be readily removed for cleaning and maintenance as needed.
