Abstract
A blower unit is disclosed which seals atop a conventional water heater. The unit utilizes a one-piece housing divided into two chambers which are in fluid communication; the first chamber houses the impeller, while the second chamber houses the exhaust flue of the water heater. An inlet plate having an inlet opening is disposed between the two chambers. The blower motor is separated from the blower housing to prevent heated exhaust gases from heating the motor. During operation, dilution air and exhaust gases are drawn into the blower housing and mixed together to reduce the temperature of the exhaust gases. The gas mixture is then expelled from the unit via an exhaust outlet in the blower housing.
