Abstract
A single burner, heat exchanger combination for particular use in a hot air furnace, includes a plurality of spaced heat exchangers, each heat exchanger having an inlet port for receipt therein of combustion gases. A unitary burner for producing combustion gases includes a burner face defined by a plurality of spaced fins for passing therethrough a combustible gas. The inlet ports of each of the heat exchangers are disposed adjacent to and in fluid communication with the passages defined by the burner face fins. A hot air furnace comprising the single burner, heat exchanger combination also includes a blower adapted to blow air over the heat exchangers and an induction blower in fluid communication with the outlets of the heat exchanger adapted to draw the combustion gases through the heat exchangers and to discharge such combustion gases outwardly from the furnace. An igniter is disposed on a support frame around the burner face for igniting the combustible gas flowing through the burner face fins for flow of combustion gases through the heat exchangers.
