Abstract
An improved wall shield and chimney support (WSCS) unit adapted to fit flush within the wall of a dwelling is disclosed. The WSCS unit includes ducts for ducting cooling air entirely around the inner wall of the unit and especially around the front lateral corners and top. The airflows are separated into outer and inner flows with the inner flow insulating the outer flow from combustion heat. The outer flow is then directed to the front of the unit top whereby a hot combustion unit can be brought into close juxtaposition with the WSCS 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 cooling of the chimney area is also increased by focusing the cooling air with baffles as it passes by the chimney. The baffles and vertical wall of a transverse duct at the top front of the unit allow the unit to support a conventional chimney without further support structure.
