ABSTRACT:
Forced hot air circulation is provided for a fireplace by a unit that can be "pushed" into place including a bank of lower tubes that are positioned in the firebox and provide a grate and including an outer housing lapping the margins of the firebox opening and having a lower manifold that feeds the forward ends of the lower tubes and having an upper register that connects to the forward ends of a bank of upper tubes. The lower tubes bend upwardly and are connected by a manifold to the upper tubes. The upper tubes are smaller and more numerous than the lower tubes and are arranged so that gas rising past the upper tubes must follow tortuous paths. Blowers are connected to the lower manifold.
