4. Stop button
5. Ventilation selector button
6. Temperature selector
Important tips about operation:
Do safety check before initial starting of the heater. Check all components for secure t (tighten screws
where necessary). Carry out a visual check whether fuel system, combustion air system, exhaust system is
unobstructed.
Normal operation of heater at altitudes up to 1500 m.
Heater can be used for short periods at altitude 1500 - 3000m. Over 3000m, the heater must be customized.
During the initial start-up of the heater, odours can be produced for a short time. This is fully normal during the
rst few minutes of operation and does not indicate a malfunction in the heater.
During the initial start-up of the heater, there may be an alarm caused by ignition failure. This is because fuel is
needed to ll in fuel pipe. Restarting heater nominally should rectify this.
Operating instructions
Pressing ventilation button on switch will activate the fan only. This will operate without combustion to
ventilate the area.
Pressing the heating selector button will start the combustion process and begin heating mode. Combustion
and ventilation lamps light up simultaneously.
As a fault occurs during operation of the heater, combustion indicator light ashes to indicate cause of the
malfunction.
Pressing the stop button. The heater stops working (combustion or ventilation). After delayed stop, the light
goes out.
Temperature regulating knob is used for setting temperature for the heater’s automatic temperature control.
Adjustment range is 10-30 ° C.
Switch between ventilation and combustion state is possible.
When switching off from heating mode, allow the unit to run on ventilation mode until the unit cools. This will
prevent fumes.
Switching on
Press heating mode button on control switch, combustion and ventilation indicating light lights up. Then,
heater starts running with glow plug working and fan running at low speed.
If there is still too much residual heat in the heat exchanger from when the heater was last used, rstly only the
fan starts up (cold blowing). Once the residual heat has been cleared, the heater starts.
Heating process
After approx. 60 seconds the fuel supply starts and the fuel / air mixture in the combustion chamber ignites.
After the ame sensor has detected the ame, the glow plug is switched off after approx. 90 sec. The heater
has reached the “POWER” stage gradually (maximum fuel quantity, maximum fan speed).
