LEAKS
Action to be taken in the event of a
suspected leak:
a) If a gas leak is suspected, close the gas
cylinder valve or other valve at the inlet
to the vehicle. Do not operate electrical
switches. Open all doors and windows to
disperse any gas escape.
b) The strong unpleasant smell of LPG will
enable the general area of the leak to be
detected. Check that gas is not escaping
from an unlit appliance. In the case of
a leak, close cylinder valve(s) and call a
competent installer to rectify the fault.
c) If a leaking gas cylinder cannot be
stopped, remove the cylinder to a safe
place in the open air in an upright
position away from drains and any source
of ignition.

Precautions and actions to be taken:
a) A fire extinguisher of adequate size and
preferably of the dry powder type should
be available.
b) The initial use of dry powder extinguishers
is recommended only if it likely that the
leakage can be stopped by closing the
cylinder valve or that the cylinder can be
speedily removed.
c) Cool with water all gas cylinders that
cannot be removed.
d) As soon as possible remove cylinders
adjacent to the fire to a safe place in order
to gain access to the seat of the fire.
ConnECTIon
Ensure that the gas regulator hose is correctly
connected to the gas cylinder in the gas bottle
compartment and that the hose connection
is tight.
Gas bottles must be fully located, seated at
the base of the bottles and restrained by the
strap provided in the dedicated compartment
position. Straps are positioned to suit 6kg, 7 kg
and 13kg bottles.
WARnInG: If using cylinders other than
those recommended, the user must
ensure these are adequately supported,
ventilation openings must not be
obstructed and the cylinders must not
cause damage to other fixtures and
fittings located in the compartment.
Open ended gas hoses must always be
protected from dirt and insects.
Before turning on the gas supply at the bottle,
ensure that all gas operated equipment in the
vehicle is turned off.
All gas equipment is supplied through a
central Gas Manifold System which has
individual isolation taps for each appliance
(Fig A), as follows:
Residual gas: no smoking! no open flames!
• Close the empty gas cylinder’s valve
• Remove the high pressure hose from
the gas cylinder and remove the slip-on
adapter, if present.
• Attach the high pressure hose to the full
gas cylinder and apply the slip-on adapter,
if present.
• Open the full cylinder’s valve.

c) Never use gas appliances without
adequate ventilation.
d) Avoid naked lights when connecting or
changing a cylinder.
e) Check the flexible hose frequently.
f) The gas is heavier than air and therefore
sinks to the lowest point.
g) Keep bottle gas containers outside (and
protected against frost). If they must be
kept inside make sure they are well away
from heat.
h) Always seek advice when in doubt.
WARnInG: Do not use appliances with a
different working pressure to 30mbar.
WARnInG: Maintain adequate spacing
of combustible materials from sources of
heat.
WARnInG: Do not use independent
portable gas appliances inside the vehicle.
Always read individual appliance
instructions
VEnTILATIon
All ventilation complies with BSEN 721 and
vents should not be obstructed in any manner
as this could lead to insufficient fresh air. In
this case the confined atmosphere becomes
depleted of oxygen which leads to the
formation of the highly poisonous gas ‘carbon
monoxide’. Carbon monoxide is odourless,
colourless and tasteless and will rapidly cause
unconsciousness and death with little or
no warning prior to collapse. THERE IS NO
DANGER WHEN ADEQUATE VENTILATION IS
PROVIDED.
Roof-mounted flue installations
All flue installations should be inspected
once a year throughout their length for
corrosion. Flues should be replaced if any
sign of perforation is found. Ensure that the
replacement is of an approved type.
CHAnGInG GAS CYLInDERS
The following procedure should be adopted:
a) Extinguish any fire, flame or source of
ignition (including cigarettes, pipes and
pilot lights) before changing gas cylinders.
b) Wherever possible change gas cylinders in
the open air.
c) Ensure that the gas cylinder valve(s) is/are
Closed before disconnecting any empty
cylinder or before removing the plastic cap
or plug on the outlet connection of the
replacement cylinder.
(Note. left hand thread.)
d) Make firm gas-tight joints. Any leaking
vapour will smell. If a leak is suspected
after changing gas cylinders and opening
valve, test by brushing with soapy water
around the joints. Bubbles will form if
vapour is leaking.
never use a naked flame.
e) Ensure that the replacement gas cylinder is
the correct one for the installation.
f) Gas cylinder valves are of various designs
depending on the type of cylinder and
the use for which it is intended and it
is essential that the correct pressure
regulator with the correct pressure
setting and capacity for the installation is
used in accordance with manufacturer’s
instructions.
g) In the case of a connection on the pressure
regulator which relies upon a sealing
washer(s) to maintain a gas-tight joint,
it is essential to check that the washer
is present, is sound and is correctly
positioned prior to making the connection.
Where the connection relies on a metal
to metal seating or bull nose connection
to obtain a gas-tight joint it is essential
that the mating surfaces are clean and
undamaged. In no case should a damaged
valve or connection be used.
h) Where connections are designed to be
tightened with a spanner, it is essential
that a spanner of the correct size is used
and that the union is firmly tightened,
hand tightness is not sufficient. When
self-sealing valves are incorporated in a
gas cylinder, connections should be made
in accordance with the manufacturer’s
instructions and tools should not be used.
