Abstract
A furnace flue gas draft inducer outlet box assembly is provided for connecting an inducer housing to a vent pipe, and comprises a plurality of differently directed openings to allow the vent pipe to be connected thereto in one of a plurality of different orientations, thereby facilitating ease of installation of the furnace. When incorporated with a condensing furnace, the inducer outlet assembly further comprises a condensate collecting system for collecting a return flow of condensate formed in a vent pipe and for delivering the condensate out of the inducer housing to prevent contact with the inducer motor, wheel and the like.
Claims5
In a furnace for raising the temperature of circulating air, comprising:
- a heat exchanger assembly defining a flow path for a heating fluid and having an inlet and an outlet,
- a heating means in proximity to said heat exchanger assembly inlet for supplying the heating fluid,
- an inducer draft means having an inducer outlet for drawing the heating fluid through said flow path, said heat exchanger assembly outlet, and said inducer outlet, and
- a vent for exhausting the heating fluid,
- an inducer outlet box assembly, comprising:
- a fluid transfer chamber being directly interconnected in fluid communication between said inducer outlet and said vent, said fluid transfer chamber including a plurality of differently directed openings being individually connectable to said vent, one of said openings being selectively connected to said vent, and
- blocking means for selectively closing off the other ones of said chamber openings, whereby said vent can be selectively connected to said chamber in one of a plurality of different directions.
