Abstract
A blower housing comprises first and second blower housing pieces for surrounding a blower fan. The first blower housing piece comprises a blower discharge section comprising an inner tubular portion, an outer tubular portion, and a drain hole. The inner tubular portion defines a blower discharge passage. The inner and outer tubular portions define an exhaust pipe cavity adapted to receive an end margin of an exhaust pipe. The tubular portions are adapted to enable condensate water that forms on the inner surface of the exhaust pipe to flow into the exhaust pipe cavity. The drain hole extends through the outer tubular portion. The drain hole is configured to enable condensate water flowing into the exhaust pipe cavity to drain from the blower housing. The first blower housing piece is a molded one-piece member.
