ABSTRACT:
A solid fuel burning heater has an inner combustion chamber housing enclosed within an outer housing with a fuel feed door in the inner combustion chamber housing being aligned with an outer housing door; an air inlet in the bottom of the combustion chamber housing has a thermostatically controlled air inflow closure valving member connected to a wire bail having an upper end encircling a cam rod connected to the outer housing door. Opening movement of the outer housing door moves the cam rod so that the air inflow closure valving member is opened to provide combustion air into the combustion chamber and prevent blowback upon the subsequent opening of the fuel feed door.
