Abstract

A coupling box for a condensing furnace having primary and secondary heat exchangers places the discharge ports of the primary heat exchanger in fluid communication with the inlet ports of the condensing heat exchanger. A baffle in the coupling box directs the flow of flue gas evenly therein to maintain temperature equilibrium so that water vapor does not condense in the coupling box.
