Abstract
A blower housing may be used with a climate control furnace or with a water heater and provides cooling of the motor that rotates the blower fan and also provides dilution and cooling of exhaust gases drawn from the furnace or water heater. The housing has an interior dilution compartment that communicates with an elongate conduit. The dilution compartment receives dilution air through the conduit, thereby reducing blower operation noise at the blower housing.
