5.2. Operating from vehicle battery
Make sure the voltage shown on the data plate of the
appliance matches the voltage of the vehicle battery
(12V or 24V).
12V DC voltage appliances are equipped with
connectors that can be plugged into cigarette lighters
(Figure 3.). For some types of vehicles, you may need
to remove the red plastic ring located on the end of
the connector. To do so, turn the plastic ring anti-
clockwise and pull it off. The appliance can then be
connected to the cigarette lighter. In 12V operation,
the appliance runs uninterrupted without temperature
control.
24V DC voltage appliances are shipped with bare wire
ends. The wire ends must be connected to a terminal
block, which is connected to the vehicle battery via a
5A fuse and 5A switch.
Whenever the engine is not running, the
appliance connector must be removed from the
cigarette lighter (12V appliance) or the switch turned
off (24V appliance). Otherwise, the appliance will
discharge the vehicle battery rapidly.

5.3. Operating from cartridge gas

Connection to the gas cartridge is described in
sections 10.3.
After connecting the gas cartridge to the appliance
and checking for gas leaks turn thermostat to
maximum position (Figure 4.B), press down the gas
safety valve hold it down for about 10 seconds and
then, press the piezo-ignition button several times in
quick succession (Figure 4.C). If the flame does not
ignite, repeat the process. (Air in the appliance gas
line prior to connection to the gas cylinder must be
purged. Only then can the gas be lit.).
The control knob has 4 positions:
: high flame (MAX) = gas supply maximum
(high ambient temperature ~ 32 °C);
: medium flame (MID)= gas supply medium
(normal ambient temperature ~ 25°C);
: low flame (MIN) = gas supply minimum (low
ambient temperature ~ 16°C);
: off-position = gas supply to burner is shut off.
Ignition of the flame can be verified through the flameview
opening (Figure 5). After you have the flame alight keep the
safety gas valve pressed down for a further 20 seconds.
To stop the gas operation the safety valve is to close and
disconnect the gas cartridge
