7 Gas system
100
B-MC - 12/18-2 - EHG-0016-01EN
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 re-
spective gas isolator tap.
Ignition safety valves must close within 1 minute after the gas flame
has extinguished. A clicking sound is audible. Check function from
time to time.
The built-in gas devices are exclusively meant for use with propane or
butane gas or a mixture of both. The gas pressure regulator as well as
all built-in gas devices are designed 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 unsuitable for use in winter.
Due to its function and construction, the gas bottle compartment is a
space which is open to the exterior. Never cover or block up the
standard forced ventilations. Otherwise gas that is emitted can not be
diverted to the outside.
The gas bottle compartment must not be used as storage space.
Secure the gas bottle compartment against unauthorised access. To
do this, lock the compartment.
The regulator tap on the gas bottle must be accessible.
Only connect gas-operated devices which have been designed for a
gas pressure of 30 mbar.
The exhaust gas pipe must be fitted tightly to the heating system and
to the vent and must be sealed. The exhaust gas pipe must not show
any evidence of damage.
Exhaust fumes must be able to escape into the atmosphere unhin-
dered and fresh air must be able to enter unhindered. For this reason,
keep the exhaust pipe and intake openings clean and unobstructed
(e.g. free from snow and ice). For this reason, no snow walls or
aprons may lie against the vehicle.
7.2 Gas
bottles
Handle full or emptied gas bottles outside the vehicle only with closed
regulator tap and attached protective cap.
Gas bottles are only to be transported within the designated gas bottle
compartment.
Place the gas bottles in vertical position in the gas bottle compart-
ment.
Fasten the gas bottles so that they are unable to turn or tilt.
Connect the gas tube to the gas bottle without tension.
If the gas bottles are not connected to the gas tube, always place the
protective cap on top.
Close the regulator tap on the gas bottle before the gas pressure reg-
ulator or gas tube are removed from the gas bottle.
Depending on the connection, unscrew the gas tube from the gas bot-
tle and screw it on the gas bottle again by hand or using an suitable
special spanner. The screw connection on the gas bottle generally
has a left-hand thread.
Do not
tighten too firmly.
