AIR FLOW SYSTEM
Stewart-Warner 10560M, 10560M24B1
BLOWER MOTOR-Turns the blower wheels to provide air to the heater. During the start cycle, it runs at a
reduced speed. This results in a richer fuel/air mixture that lights easier (same as 1056C24).
VENTILATION BLOWER WHEEL-Forces air through the heater, around the heat exchanger, and out to the
vehicle ductwork (same as 10560C24).
COMBUSTION BLOWER WHEEL-Draws air from outside vehicle and forces it through duct and into combus-
tion chamber.
COMBUSTION CHAMBER-Place where fuel, airflow, and ignition systems come together, and burning oc-
curs. Hot gases are forced into heat exchanger.
HEAT EXCHANGER-Provides a large surface area for heat transfer to take place between combustion gases
and ventilation air. The hot gases are forced out exhaust port and piped out of vehicle
