Press the button so that the hose break valve opens.
If the hose break valve is closed, the gas appliances
cannot be lit.
CHANGING GAS BOTTLES
Change gas bottles as follows:
1 Turn off all gas appliances in the motorhome.
2 Close the gas bottle’s master valve.
3 Unscrew the hose from the gas bottle.
The connector has a left-hand thread and screws off
in a clockwise direction.
Certain models have a hose break valve between
hose and bottle.
Leave the hose break valve on the hose.
4 Change the gas bottle.
Secure the new gas bottle.
5 Screw the hose (hose break valve) securely to the
new gas bottle.
6 Open the gas bottle’s master valve.
Check that there are no leaks.
7 Models with a hose break valve only:
Open the hose break valve by holding the button
down for a few seconds so that the gas pressure in
the hose equalises.
8 Turn on the required gas appliances.
After changing a bottle, there may be air in the gas
lines. This may make it difficult to light, for example,
the hob.
Repeat attempts until gas finally reaches the
appliance .
In the winter, moisture trapped in the connection threads
could freeze and impede the supply of gas. Open the
master valve momentarily before fitting the hose. This
blows away any moisture (which cannot then freeze to
form an ice plug).
In view of the fire risk, take great care.
The gas bottle must be stored upright.
BOTTLED GAS SYSTEM
Certain models have a leak indicator.
Check the gas system for leaks as follows:
1 Turn off any gas appliances (hob, boiler, refrigerator)
and wait till the flame failure safety devices have coo -
led.
2 Open all the ventilation valves in the motorhome.
Open the hob’s operating valves too.
3 Press the button on the leak indicator.
4 Check if there is gas bubbling through the liquid in the
glass dome. There must be no bubbles in the liquid.
Watch for at least 10 seconds. Preferably, the test
should be conducted for one minute.
If bubbles appear even though all the gas appliances
are turned off, there is a leak in the gas system.
Close the master valve on the gas bottle immediately
and visit the nearest KABE service workshop to have
the leak repaired.
WARNING!
Flammable gas is dangerous!
When changing gas bottles, ensure
that the area is free from naked flames
and glowing or hot objects that may
ignite the gas.
