ABSTRACT:
An assembly using horizontally oriented heat exchange pipes (10, 10a) and a blower unit (11) for providing heated air adjacent to a furnace (100) and hot water heater (102) is described. The blower unit includes heat exchanger pipes with a downwardly inclined section (10d) and an upwardly inclined section (10e) from horizontal to and from a low point (10c) with a drain (12) for condensed liquids from the flue products exhaust pipe (10a) at the low point. The drain removes condensed liquids which are highly corrosive from the exhaust products pipe without allowing flue gases to pass through the drain.
