THEORY OF OPERATION
The Fuel System: The hose/regulator assem-
bly attaches to the propane gas supply. The
propane gas moves through the automatic
control valve, burn rate adjustment valve and
out the injector.
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 high voltage ignitor
sends voltage to the spark ignitor. The spark
ignitor ignites the fuel and air mixture.
The Safety Control System: This system
causes the heater to shut down if the flame
goes out. The motor will continue to run, but
no heat is produced.
