Abstract
A non-dilution air water heater blower for use in expelling exhaust gases from a water heater. The water heater blower includes a one piece blower housing defined by an outer wall having an upper section and a lower section. An inlet plate is positioned between the upper section and the lower section of the blower housing to define an upper chamber and a lower chamber. The lower chamber of the blower housing surrounds the exhaust flue from the water heater. A blower motor is attached to the outside surface of the blower housing. A rotating impeller coupled to the blower motor and positioned in the upper chamber draws exhaust gases from the water heater into the lower chamber through an inlet aperture formed in the inlet plate and out of an exhaust outlet formed in the upper chamber.
