Abstract: A furnace blower assembly includes a blower housing a blower and a motor. The blower is positioned within the housing and is adapted to rotate relative to the housing. The motor is coupled to the blower. The housing defines an outlet having an external periphery and an internal periphery. The external periphery or the internal periphery of the outlet is adapted to be fitted to a portion of the external periphery or the internal periphery of the duct. The outlet defines a longitudinal axis. The outlet has a peripheral edge and a protrusion extending outwardly from the external periphery or the internal periphery of the outlet. The protrusion is spaced from the peripheral edge of the outlet and is adapted to abut the peripheral edge of the duct.
