Abstract
Abstract The fireplace includes a hearth section having a screen-covered opening in its front wall, and a hollow canopy section fastened over the hearth section and extending beyond the sides and front thereof so that spaces are formed between the sections at the front and sides of the fireplace. An andiron and imitation logs may be placed in the hearth section. A fan and electrical heating elements are mounted in a chamber within the canopy. This chamber has an inlet opening on the interior of the canopy, and an outlet opening at the front of the fireplace. When the fan operates, air is drawn into the chamber through the screened opening in the hearth section and the lateral spaces between the sections, and is heated by the electrical elements to be discharged through the outlet and send heat into the room.
