en
First start-up
After installation or maintenance, if the fuel line is empty, the heater may not start
at the the first attempt. Start-up phase with empty fuel line is longer than normally
and might take about 15 minutes. If the heater doens’t ignite the red combustion
indicator light will start to blink after start-up.
Turn off the heater. The device cannot be restarted until the cooling phase is com-
pleted.
When the cooling phase is finished, switch the heater on again.
If the device does not start after two attempts, it cannot be started again: the heater
will lock itself (lights blink to indicate this). Find out the reason why the unit didn’t
start.
If the heater iginites during two attemps the red combustion indicator (1) will go on.
After locating the fault, release the locking (instructions in the maintenance section)
and start-up the unit.
Depending on the length of the fuel hose, the heater may have to be started up
several times during priming. Keep an eye on how the fuel travels in the fuel hose
while starting up the heater.
Adjusting the heat
Adjustment of temperature can be done by using thermostat (recommended use)
or manually.
The desired mode is choosen by turning the regulation knob (2) min - max - min –
max, by doing this the unit is switched to either to thermostat- or to manual mode.
When thermostat mode is chosen the thermostat light (5) is on. In manual mode
the thermostat light (5) is off. Note ! the heater will remember it’s last mode ie. if it
is shut down in thermostat mode next time when ignited it it will start in the same
mode ie. thermostat mode.
Thermostat mode
Temperature is controlled by the thermostat (recommended use)
The device starts when the heating switch (3) is pressed in continuously for at least
2 seconds, after which the yellow power indicator light (9) lights to indicate that the
power is on.
The red combustion indicator light (1) will be lit, when the burner flame has been
ignited and combustion has stabilised, about 2.5 - 4 min after starting the heating
cycle. The starting phase will complete after about 11 minutes. After this phase, the
heater will run according to set power, adjustable by turning the knob.
After the heater has passed the ignition phase, you can adjust the thermostat set-
ting using the temperature control knob (2). Turn the knob to set the temperature to
your desired setting.
