ABSTRACT:
A furnace includes at least one heat exchanger with first and second plate members secured together to define passageways that form serpentine flow paths between an inlet passageway and an outlet passageway. The inlet passageway receives hot products of combustion from a burner which extends into it. A blower induces the flow of the combustion products through the heat exchanger. A second blower induces the flow of air over the surfaces of the exchanger.
