ABSTRACT:
A fireplace, comprising an inner jacket and an outer jacket defining an air circulation path therebetween, is provided with a smoke chamber convection wall and a baffle convection wall oriented so as to efficiently transfer heat from the fire box to the air circulation path. A damper plate and a back draft blocking wall are positioned in the fireplace so as to effectively block back drafts in both the open and closed damper positions. The fireplace also includes exterior controls whereby the damper plate and an outside air vent can be controlled in a safe manner. A clean out shaft and a draft control are also provided to facilitate safe operation of the fireplace.
