ABSTRACT:
The specification discloses a mobile home heater taking combustion air from the outside and operable selectively as a stove and a fireplace and being double walled in its back sides and bottom. In operation as a stove, combustion air flows into a bottom passage covering the bottom of the fire chamber, up a back passage covering the back of the fire chamber and down a preheating passage in the back passage and into the lower portion of the fire chamber, secondary air also flowing from the back passage into the upper portion of the fire chamber. For fireplace operation, a door is opened to the fire chamber and also opens ports from the bottom passage to supply air through the door opening, a thermostat controlled damper to the preheating passage closing. An injection tube leads from the back passage into a stack to minimize condensation in low combustion operation, and a second air injection tube in the upper portion of the stack has a thermostat controlled inlet valve closed when the stack is hot.
