ThEORY OF OPERATION
The Fuel System:
The hose / regulator assembly attaches to the propane gas supply. The propane gas moves
through the solenoid valve and out the nozzle.
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 direct spark ignitor (DSI) sends voltage to the ignitor. The 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.
