THEORY OF | The Fuel System: The motor turns the fuel pump. The fuel pump pulls fuel from | |||||
the fuel tank. The fuel pump pushes fuel through a filter and a solenoid valve and out | ||||||
OPERATION | ||||||
the burner head nozzle. 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 electronic ignitor sends voltage to the spark plug. The | |||||
| spark plug ignites the fuel and air mixture. |
|
|
| ||
| The Burner Control System: This system causes the heater to shut down if the | |||||
| flame goes out. It also allows the fan to continue running after normal shutdown of | |||||
| heater. This cools the combustion chamber. |
