Owners are advised to allow some fresh air
circulation in the awning space when such
appliances are in use.
PRECAUTIONS
a) Never look for a leak with a match. Always
use a soap solution or its equivalent when
testing connections. Do not operate any
electrical apparatus whatsoever, especially
light switches. If the leak is not obvious, the
vehicle should be evacuated and qualified
personnel consulted.
b) Always turn off the gas cylinder valve or
inlet to the vehicle when the appliances are
not in use.
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.
