BASIC HEATER OPERATION
The personnel heater produces heat by burning fuel. You need three things to make the heater work.
o Fuel for burning
o Away to light the fuel
o A supply of air to mix with the fuel
To see how these three things are brought together in the heater, see the flow diagram below.
o The fuel system controls fuel flow into the combustion chamber.
o The ignition system lights the fuel.
o The airflow system sends air into the combustion chamber for burning.
After combustion, the heater works like this:
o The hot air from the combustion chamber goes through the heat exchanger.
o The heat exchanger transfers the heat to fresh air supplied by the airflow system.
o The heated fresh air is sent through the vehicle ductwork.
o The exhaust gases are sent outside the vehicle.
