Abstract
A secondary condensing heat exchanger for use in a multi-poised furnace that includes multiple single pass heat transfer stages. Each stage includes a housing having an entrance at one end and a pair of outlets at the other end. The walls of the housing are arranged to conduct condensate formed in the housing through one or both outlets, depending on the orientation of the furnace. Lateral flow restrictors are mounted in the housing to direct flue gas products entering the housing back and forth across the housing.
