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 burner control 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.

1. The amount of propane gas in tank(s)
2. The temperature of tank(s)
The chart below shows the number of 45 kg (100 pound) tanks needed to run this
