AIR FLOW SYSTEM
BLOWER MOTOR-Turns impeller, combustion fan assembly, and fuel atomizer.
IMPELLER-Forces air through heater, around heat exchanger, and out to vehicle ductwork.
BURNER FAN ASSEMBLY-Draws air from outside vehicle and forces it through fuel atomizer.
FUEL ATOMIZER-Combines fuel and combustion air and creates a fine mist.
HEAT EXCHANGER-Place where fuel mist is burned and heat is transferred from hot gases inside to fresh air
outside. Hot gases outside are forced out exhaust port and piped out of vehicle.
SOLENOID VALVE-Regulates amount of air drawn in by combustion fan assembly to control fuel/air mix ratio.
