AIR FLOW SYSTEMStewart-Warner and 10560C24, 10560GBLOWER MOTOR-Turns the blower wheels to provide air to the heater. During the start cycle it runs at areduced speed. This results in a richer fuel/air mixture that lights easier.VENTILATION BLOWER WHEEL-Forces air through the heater, around the heat exchanger, and out to thevehicle ductwork.COMBUSTION BLOWER WHEEL-Takes a portion of the air forced into the heater by the ventilation blowerwheel and forces it into the combustion chamber.COMBUSTION CHAMBER-Area where fuel, air flow, and ignition systems come together and burning oc-curs. Hot gases are forced into the heat exchanger.HEAT EXCHANGER-Provides a large surface area for heat transfer to take place between combustion gasesand ventilation air. The hot gases are forced out the exhaust port and piped out of the vehi-cle.1-15TM 9-2540-205-24&P
