Abstract
A solid fuel furnace is disclosed as including a firebox disposed inside of a heating chamber through which air to be heated is passed. A pair of baffles guides the air through the heating chamber to progressively heat the air. In addition, an auxiliary air system is provided to inject air into the fire when there is a heating demand to increase combustion and provide more heat when it is most needed. A modified solid fuel furnace is also disclosed which includes a combustion chamber having a door designed to prevent flash-back when the door is opened, a valve for preventing a flow of combustion air to the combustion chamber when the temperature in the combustion chamber rises above a present level, and a manual override for the valve. In addition, a plurality of thermostats and switches are inter-connected with a circulating air blower and a combustion air fan for combined regulation of the temperature in the combustion chamber, the temperature of the circulating air and the temperature in the room to be heated.
