OPERATING PRINCIPLE
The fuel supply system: The fuel pump uses pressure to lead the fuel into the
nozzle, which subsequently injects the fuel in minuscule particles into the combustion
chamber, see illustration.
Immediate ignition process: As soon as the transformer is powered (230V), it
converts this into high voltage, which the spark plug discharges. The spark ignites
the fuel particles in the combustion chamber.
Cooling and ventilation process: The fan in back of the heater (2
nd
fan) supplies
the heater with oxygen for burning and blasting the hot air. The fan underneath (1
st
fan) cools the surface of the heater.
Overheating protection: This heater is manufactured with a temperature-limit
control that switches off the heater whenever the internal temperature increases to
an unsafe level. When the temperature decreases to below the set limit, you can
restart the heater. If this occurs, your heater may need maintenance. Do not ignore
this signal!
Protecting the electric circuit: A fuse protects the components of the electric circuit
against damage. If you suspect that the fuse has been burnt, send the device for
repair.
Flame sensor: The heater uses a photocell to ‘see’ the flame in the combustion
chamber. If the flame is distinguished, the sensor will stop the heater and it will
switch off.
