Working principle
Fuel system:
The heater is fitted with an electric air pump that pushes air through
the air pipes along the fuel inlet and forces the fuel from the tank into the fuel nozzle.
This mixture of fuel and air is then sprayed into the combustion chamber as a fine
mist.
Ignition mechanism:
The electronic ignition creates a charge on a specially
developed electrode/sparkplug. This uses a spark to ignite the mixture of fuel and air,
as described above.
Air system:
The heavy motor drives a ventilator that sends air into and around the
combustion chamber. The air is then heated up and driven out of the front of the
heater.
Safety devices:
Temperature limiter:
This heater is fitted with a temperature limiter that switches the
heater off if the internal temperature rises to an unsafe level. If this safety device is
triggered, it may mean that your heater needs to be serviced.
If the temperature has dropped to under the reset-temperature, the heater can be
used again.
Electrical system safeguard:
The heater’s electrical system is protected by a safety
fuse that is attached to the PCB system. The fuse safeguards the PCB system and
other electrical components against damage. If the heater does not work, first check
the fuse and replace it with a similar fuse if necessary.
Flame control:
The heater uses a photoelectric cell to keep an eye on the
combustion chamber when the heater is operating. It will switch the heater off if the
flame goes out and will send an error message to the display.
Fuel
OK-heaters work with paraffin or diesel; paraffin gives the cleanest combustion. Be
aware that the more dust and dirt that is contained in the fuel, the more ventilation
will be required! Use the cleanest fuel possible.
Note:
paraffin may only be stored in blue containers; red containers are associated
with petrol!
NEVER use other fuels such as petrol, alcohol, oil compounds or similar in this
heater; this could lead to fire or explosion!
NEVER store paraffin in direct sunlight of near a source of heat.
Do not store paraffin in living/work areas but in a well-ventilated area such as a
shed, storage area or similar.
NEVER use paraffin from the previous season. Paraffin deteriorates in quality and
will not burn properly as a result.
