Inducer collector box seal for induction condenser furnace

In an induction type furnace in which an inlet of an inducer fan housing is coupled to an outlet of a heat exchanger element and wherein said inducer fan housing has a substantially planar back wall in which said inlet is centrally disposed and said heat exchanger element has a front wall disposed parallel to said inducer housing back wall and spaced a predetermined short distance therefrom with said heat exchanger element outlet being disposed in said front wall, the improvement, wherein said heat exchanger element outlet and said inducer fan housing inlet is positionally offset from one another and comprising a sealing arrangement surrounding said inlet and said outlet for fluidly and sealably coupling the heat exchanger element to the inducer fan housing and permitting passage of vent gases from said heat exchanger element into said inducer fan housing inlet;

• the sealing arrangement including first and second congruent continuous skirts each projecting from a respective one of said heat exchanger element front wall and said inducer fan housing back wall and surrounding the associated one of said outlet and said inlet, each said skirt having a tip edge;
• said first and second skirts mating at associated tip edges thereof, and including means on the respective tip edges to form a gasketless seal therebetween.
