    Abstract: A draft inducer blower assembly for use with a water heater has a housing, a motor, and a fan. The housing has an exhaust volute surrounding the fan and a base adapted to be mounted atop a water heater. The housing has an inlet port adapted to receive exhaust gas from the water heater. The fan is connected to the motor for rotation about a rotation axis. The exhaust volute has a cut-off at a cut-off angle relative to the rotation axis. The exhaust volute has an exhaust outlet passageway that extends to an exhaust port. The exhaust port is lower than the top of the exhaust volute.

    Abstract: A water heater system comprises a water tank, a burner plenum, a flue, a blower, a combustion air passageway, a dilution air passageway, an upstream manifold, and a downstream manifold. The upstream manifold divides air from the blower so that some air flows through the combustion air passageway to the burner plenum and some air flows through the dilution air passageway to the downstream manifold. The downstream manifold combines the air from the dilution air passageway with combustion products from the flue.

    Abstract: A blower assembly includes a centrifugal fan and a motor assembly. The centrifugal fan has a plurality of axially extending impeller blades, a first axial end, and an air inlet. The air inlet is at the first axial end of the centrifugal fan. The motor assembly comprises a stator, a rotor, and an air directing surface. The air directing surface is shaped and configured to direct air drawn into the air inlet radially outwardly toward the impeller blades. The air directing surface extends generally along the rotor axis from its first end to its second end. At least a surface region of the air directing surface generally circumscribes the rotor axis and diverges radially outwardly as such surface region of the air directing surface extends away from the first end toward the second end.

    Abstract: A water heater system comprises a water tank, a burner plenum, a flue, and a dilution air blower system. The dilution air blower system comprises a blower, a dilution air passageway, and a venturi system. Air from the blower is forced through the dilution air passageway and discharged toward the venturi system. When the dilution air blower system is attached to the water heater system, air discharged from the dilution air discharge passage via the blower passes through a converging region, throat region, diverging region and exit passage of the venturi system and draws combustion products through the flue and out the venturi system.
