7 Gas Fittings
Chapter Overview
This chapter contains instructions regarding the gas fittings of the caravan.
The instructions address the following topics:
safety
changing the gas bottles
gas isolator taps
external gas connection
The operation of the gas operation appliances of the caravan is described in chapter 9.
7.1 General
Before commencing the journey, close all gas isolator taps and the regulator tap.
Have the gas fittings checked by an authorised specialist workshop according to the
national regulations before commissioning. This also applies for not registered vehi-
cles. For modifications to the gas fittings have the gas fittings immediately checked
by an authorised specialist workshop.
Have the gas fittings repaired or altered by an authorised workshop only.
In case of a defect of the gas fittings (gas odour, high gas consumption) there is an
explosion hazard! Immediately close regulator tap on the gas bottle. Open windows
and doors. Do not smoke; do not ignite any open flames, and do not operate electric
switches (light switches a.s.o.). Have the defect repaired by an authorised workshop.
Open the lifting roof before taking open sources of combustion (gas cooker) into serv-
ice.
Do not use the gas cooker for heating purposes.
If the caravan or gas equipment are not used, close the regulator tap on the gas bot-
tle.
If there are several gas devices, each gas device must have its own gas isolator tap.
If individual gas devices are not in use, close the respective gas isolator tap.
Thermocouple must close within 1 minute after the gas flame has extinguished. A
clicking sound is audible. Check function from time to time.
When refuelling the towing vehicle, no source of combustion (gas cooker, gas heater,
boiler, etc.) is to be in operation.
The installed devices are meant for use with propane or butane gas or a mixture of
both. The gas pressure regulator as well as all installed gas devices are set for a gas
pressure of 30 mbar.
Propane gas is capable of gasification up to -42 °C, whereas butane gas gasifies at
0 °C. Below these temperatures no gas pressure is available. Butane gas is unsuita-
ble for use in winter.
Inspect the gas tube fitted to the gas bottle connection for tightness. The gas tube
should have no tears and should not be porous. It is recommended that the gas tube
be replaced every 12 months, or earlier if necessary.
