Abstract

An induced draft type of furnace or heating system (10) is operated with a fan (31) that draws cooling air through the motor (24) that operates the fan or blower. The cooling air is drawn through passage means (23, 27, 29, 35) in the motor and then into the vent stack (11) of the furnace where the cooling air is mixed with the flue products and the mixture is forced out of the vent stack of the furnace.
