4 - Functions of the components
There are four basic systems that make up the heater: the fuel system, the ventilation system, the ignition
system and the flame control system.
 Fuel system: The pump takes fuel from the tank and pressurises it. It pushes it through the filter and
the pump to make it exit as a very fine mist from the nozzle in the combustion head.
 Ventilation system: The motor turns the fan. It pushes air into the combustion chamber. The air
entering the combustion chamber mixes with the fuel mist for combustion. The flame that is created
lightly touches the internal wall of the combustion chamber. This chamber reaches a temperature
that is so high that the front baffle becomes incandescent, heating anything in front of it by radiation.
 Ignition system: The transformer sends voltage to the electrodes that ignite the mixture of air and
fuel.
 Flame control system: This system causes the machine to turn off if the flame is interrupted. Upon
subsequent ignition, the equipment must be reset manually.
 Electrical system: This system allows heater operation, in all of its parts, as soon as it is connected
to suitable mains voltage that conforms to that shown on the heater's identification plate.

Fuel system

As shown in the fuel system diagram below, the fuel is taken in by the pump in the burner. The fuel passes
from a rigid pipe and continues up to the line filter. Here the fuel is filtered by a cartridge, pressurised and
sent at suitable pressure to the nozzle. At the nozzle, the fuel is filtered a third time before being suitably
vaporised.
