Note: The regulator valves should be in the
'OFF' position when driving.
Note: No safety device on this system
Gas Hoses
High-pressure hoses or pigtails as they
are called must be used with the new style
regulator.
High-pressure hoses incorporate a safety shut
off valve for the use of the en-route heating
system
LPG cylinder i.e. Propane, Butane, BP and
Camping Gaz cylinders all have unique bottle
adaptor connections. It is important to check
you have the correct hose and adaptor to suit
your gas cylinders.
Push on hoses are no longer permitted under
the latest regulations.
The new high-pressure hoses have threaded
connections and must be securely attached to
the regulator and to the gas cylinder.
Ensure that there is a constant rise in the
flexible gas hose between the gas cylinder
outlet and the regulator elbow.

!
WARNING: Inspect flexible gas hose(s)
regularly for deterioration and renew as
necessary with the approved type, in any
case no later than 5 years after the date of
manufacture marked on the hose.
When replacing the en-route hose ensure
the new hose incorporates a safety shut off
valve (Hose rupture protection).
!
WARNING: Ensure that the high
pressure hose is not excessively twisted or
under stress when connected to the LPG
cylinders and regulator.
!
WARNING: Always ensure the gas
supply is isolated at the LPG cylinder (and
not at the regulator) whilst the vehicle is in
storage for any period. It is important to
ensure that the high pressure gas hose has
a continuous rise from the bottle cylinder to
the regulation to allow any condensate to fall
back into the gas bottle cylinder.
Cylinder compartment
All cylinder compartments have four plastic
mouldings per cylinder position fitted to the
floor of the compartment that are designed to
fit both steel and BP Gas Light cylinders. Two
straps are provided for retaining the bodies of
the cylinders at mid to high level.

Types of gas

Propane
Propane is supplied in red, or partly red
cylinders which have a female left hand
threaded connector.
Scandinavian countries use the same
connector.
Germany and Austria supply propane with a
male connection.
Propane will work at temperatures as low as
-40°C and is therefore suitable for all winter
motorhoming.
