Connecting services

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.
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.
Fire
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
regulator, 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:
RED - Water Heater/
Combination Boiler
WHITE - Space Heater
BLUE - Fridge
GREEN - Oven
