Abstract: A fireplace is situated in the wall of a room of a mobile home. It includes a firebox open to the interior of the room and connected to a stack outside of, and spaced from the room. Casing means surrounds the firebox and provides an outer passageway around the outside of the firebox and an inner passageway between the outer passageway and the firebox. Heat from combustion in the firebox induces air flow from outside the room through the inner passageway, around the firebox and into the room to heat the room and to supply air for further combustion. Such combustion heat also induces air flow from outside the room, through the outer passageway to outside of the structure, thereby tending to cool the exterior of fireplace.
