1. A blower housing comprising a first blower housing piece and a second blower housing piece, the first and second blower housing pieces being adapted and configured to be connected to one another in a manner to collectively surround a blower fan, at least one of the first and second blower housing pieces defining a wall of the blower housing extending around a radial periphery of the blower fan, at least one of the first and second blower housing pieces comprising a blower discharge section, the blower discharge section being adapted to be coupled to an exhaust pipe, the blower discharge section comprising:
an inner tubular portion and an outer tubular portion, the inner tubular portion having an inner surface and an outer surface, the inner surface of the inner tubular portion defining a blower discharge passage, the outer tubular portion surrounding the inner tubular portion, the outer tubular portion having an inner surface and an outer surface, the inner surface of the outer tubular portion and the outer surface of the inner tubular portion being spaced sufficiently apart to define an exhaust pipe cavity, the exhaust pipe cavity being adapted to receive an end margin of the exhaust pipe to enable the end margin of the exhaust pipe to be positioned between the inner tubular portion and the outer tubular portion, the inner tubular portion and the outer tubular portion being adapted and configured to enable condensate water that forms on the inner surface of the exhaust pipe to flow into the exhaust pipe cavity;
at least one drain hole in fluid communication with the exhaust pipe cavity, the at least one drain hole being adapted and configured to enable condensate water flowing into the exhaust pipe cavity to drain from the blower housing via the at least one drain hole;
the first blower housing piece being a one-piece member; and
the inner tubular portion extending longitudinally from an upstream end to a downstream end, the inner tubular portion upstream end being in a plane that intersects the wall of the blower housing.
