THEORY OF OPERATION | ||
The Fuel System: The hose/regulator assembly | ||
attaches to the propane gas supply. The propane | ||
gas moves through the automatic control 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 spark transformer | ||
and ignitor lights the main burner. |
| |
The Safety Control System: This system causes the | ||
heater to shut down if the flame goes out. | ||
