Theory of Operation
Fuel System: This heater is equipped with a high-pres-
sure pump. The pump draws fuel up from the fuel tank to
the nozzle in the burner head. It is sprayed into the
combustion chamber in a fine mist where it is mixed with
air for combustion.
Quick-Fire Ignition: A transformer sends high voltage to a
two-pronged spark plug. The spark ignites the fuel/air
mixture as it is sprayed into the combustion chamber.
Air System: A blower motor assembly forces air around
the combustion chamber, where it is super-heated and
forced out the front of the chamber. A cooling fan blows air
up and around the chamber during operation and also
runs during the cool-down period.
Electrical System Protection: The heater’s electrical
system is protected by a circuit breaker that protects the
system components from damage. If the heater fails,
check the fuse first, and replace if necessary (see page
10).
Flame Sensor: The heater uses a photocell to see the
flame in the combustion chamber. Should the flame extin-
guish, the sensor will stop electrical current and the heater
will shut off.
Tipover Sensor: The heater uses a tipover sensor.
