ABSTRACT:
The present invention involves a gas furnace having a condensate trap formed in the transition box between the secondary heat exchanger and the exhaust blower. The gas furnace includes gas burners which burn fuel within the passageways of the heat exchanger are induced through its internal passageways by an exhaust blower. The transition box connects the heat exchangers with the exhaust blower and provides a location for condensate to collect for discharge through the integral condensate trap assembly. Also, the exhaust blower housing has drainage ports to convey condensate from the blower and vent back to the condensate trap.
