From 12 Volt Vehicle Battery; From Lp Bottled Gas - Domestic Chescold F400 Manual

5.2. Operating from 12 Volt
vehicle battery
Make sure the voltage shown on the data plate of the
appliance matches the voltage of the vehicle battery
(12V).
In 12V operation, the appliance runs continuously
without temperature control.
The appliance is supplied with a matching pair of
12 Volt MALE + FEMALE plugs (see 9,2
connection to vehicle power source).
For 12V operation, make sure, if the engine is not
running, that the switch is turned off. Otherwise, the
appliance will discharge the vehicle battery when in
operation.
5.3. Operating from LP 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 (Figure 4) turn thermostat to
maximum position, press down the gas safety valve
and at the same time, press the piezo-ignition button
(marked with a star) 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.)
Ignition of the flame can be verified through the flame-
view opening (Figure 5). After you have the flame
alight keep the safety gas valve pressed down for a
further 10 seconds.
