ABSTRACT:
A blower is attached to the forward end of a tubular base of dihedral form, which extends first along a lower side portion of a fireplace firebox and then along the lower rear portion of the firebox and terminates in a closed end. A short transfer duct extends upwardly from an intermdiate part of the rear portion of the base to an intermediate part of an elevated air-heating box. The air-heating box is elongated in the horizontal direction and leans forwardly. An outlet tube extends forwardly and upwardly from each of its ends to a discharge position at an upper forward corner portion of the fireplace firebox. The side portion of the tubular base includes a flange at its rear end, by which it is bolted to a similar flange at the end of the rear portion of the tubular base. A similar flange is provided at the opposite end of the rear portion of the tubular base and the side portion of the tubular base is invertible so that it can be attached to the opposite end of the rear portion of the tubular base. Lower portions of the flanges serve as support legs for the tubular base. A third point of support is provided at the forward end of the side portion of the tubular base.
