The rotating wheel includes a brake; put this on when using this heater! If the
heater is placed on a slight incline, put a stone or something similar in front of the
wheels. Do not use the heater on a severe incline!
Working principle
Fuel system:
The heater is equipped with a motor-driven, rotating fuel pump that
pushes fuel through the fuel pipes and onto the nozzle at a pressure of 7-12 kg/cm².
The nozzle then sprays the atomised fuel into the combustion chamber. The air fan
ensures that sufficient air is added.
Ignition mechanism:
A transformer converts the mains network voltage into a high
voltage (16.5 kV) to create a spark in the sparkplug. This ignites the fuel in the
combustion chamber. The sparks stop after 20 seconds; combustion continues as
long as fuel is being added.
Air supply and cooling system:
The heater requires a great deal of air (oxygen) for
the combustion process; the air fan regulates effective combustion. Too much air will
lead to a blue flame, too little will give a yellow one. Ineffective combustion can lead
to problems with ignition and soot and may create air that makes you feel nauseous.
If the combustion chamber gets too hot, the cooling and air fans will start to work in
order to prevent overheating.
Electrical system safeguard:
This heater is fused in order to protect it against high
voltage. A spike in power or similar will burn the fuse. If the heater does not work,
always check the fuse in the PCB first.
Flame control:
The heater is equipped with a photoelectric tube that seeks out the
flame and checks it for balanced combustion. If the flame goes out or burns unsafely,
the flame safeguard will stop combustion and an error message will then be sent to
the display.
Overheating safeguard
This heater is equipped with an overheating safeguard that
checks for overheating during combustion. If the temperature in the heater (outside
the combustion chamber) rises above 80 to 100°C, an error message is sent to the
display.
Thermostat function:
This heater has a built-in thermostat button which can be
used to set the target temperature. The heater will work until the set temperature is
reached (checked by the temperature sensor and shown on display). If the set
temperature is lower than the current temperature, the heater will not work.
Fuel
The fuel for this heater is paraffin or diesel; paraffin is preferable. In general, diesel
does provide heat but paraffin is cleaner and so the nozzle clogs up less quickly and
