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 bottled gas
Connection to the gas cylinder is described in
sections 9.3. and 9.4.
After opening the valve of the gas cylinder 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 (marked with a star Figure 4. C)
several times in quick succession. 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 valve of the gas cylinder (or
the pressure regulator) is to close.
