THEORY OF OPERATION
The Fuel System:
The air pump forces air through the air line. The
air is then pushed through the nozzle. This air causes fuel to be lifted
from the tank. A fine mist of fuel is sprayed into the combustion
chamber.
The Air System:
The motor turns the fan. The fan pushes air into
and around the combustion chamber. This air is heated and provides
a stream of clean, hot air.
The Ignition System:
The ignition control assembly provides
power to the ignitor. This ignites the fuel/air mixture in the combus-
tion chamber.
The Flame-Out Control System:
This system causes the heater to
shut down if the flame goes out.
