  • Patent number: 4074854
    Abstract: A heating apparatus has a firebox, ash pit and flue enclosed in a casing wherein the fire is maintained toward the rear of the firebox and the ash pit is positioned at the front and below the firebox. The flue connects to a rear portion of the firebox and extends toward the front of the casing and then rearwardly where the fumes are exhausted to the atmosphere. Electrical controls adjustably open a vent located in the front of the ash pit to control the size of the fire by controlling the available oxygen. A fan mechanism circulates fresh air around the firebox and the flue inside the casing to provide a source of heated air for convection heating. The fan is controlled by a temperature controller to maintain the heated air within specified temperature limits.
