4.5 Gas operation (Liquid gas)
The refrigerator must be operated using
liquid gas (propane, butane) (no natural gas
or town gas).
When using LPG gas, please consider that
the burner needs cleaning at shorter inter-
vals due to the gas combustion method (2
- 3 times per year recommended.
The national regulations of the respective
country must be observed.
For physical reasons, gas ignition faults
could occur starting from an altitude above
sea level of approx. 3280 ft. / 1000 m (No
malfunction!)
On the initial refrigerator start-up or after a
cylinder change, air may be trapped in the
gas line. To purge the air from the lines,
switch on the refrigerator and any other gas
appliances (e.g. stove) for a short time. The
gas ignites without delay.
Each refrigerator with manual ignition is
equipped with an automatic flame safety
valve which interrupts the gas supply auto-
matically after approx. 30 seconds when
the flame has extinguished.
WARNING!
As a basic rule, gas operation is prohibi-
ted in petrol stations!
Prior to starting the refrigerator in gas
mode :
Open the gas cylinder valve.
Open the shut-off valve for gas supply to
the refrigerator.
