ABSTRACT:
A forced air circulation heating unit is formed of a U-shaped conduit placed on the floor of the fireplace and a fan forcing air through the conduit to be heated in the fireplace and projected into the room. Jets are provided on the conduit to direct streams of air from legs of the conduit toward a base joining the legs in order to completely burn fuel thereby reducing carbon monoxide, to facilitate starting of a fire and to reduce smoking. The base of the conduit has an increased cross-sectional flow of air and the jet streams cooperate with the base to assure that the hottest part of the fire is produced by coals on and adjacent the base thereby increasing heat obtained from the unit and saving fuel.
