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 a n inlet port for receipt therein of combustion gases. A unitary burner for producing combusti on 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 t he 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 th e heat exchangers.
