CARADON PLUMBING Ltd.
pursues a policy of continuing
improvement in the design and performance of its products. The
right is therefore reserved to vary specification without notice.
The Gas Safety (installation & Use) Regulations, Statutory
Instrument 1994, No. 1886,
impose certain legal obligations on
gas users.
CHANGING GAS CYLINDERS
a.
Ensure that the replacement gas cylinder is the correct one for
the installation.
b.
Extinguish any fire, flame or source of ignition (including cigarettes,
pipes and pilot lights) before changing the gas cylinders.
c.
Change cylinders with caution.
d.
Ensure that the gas cylinder valve(s) is/are closed before
disconnecting an empty cylinder or before removing any plastic
cap or plug on the outlet connection of the replacement cylinder.
Never use tools on cylinder valves, hand wheels or levers.
Note.
Cylinders with threaded connections have a left hand thread.
For cylinders with self-sealing clip-on valves, ensure that the
regulator tap is closed before disconnection.
e.
Ensure that the replacement cylinder connections are gastight.
Any leaking vapour will have a distinctive odour. Test by using
leak detection solution around the connections - bubbles will form
if vapour is leaking.
NEVER USE A NAKED FLAME
f.
It is essential that the correct pressure regulator, with the correct
pressure setting and capacity for the installation, is used in
accordance with the manufacturer's instructions.
g.
In the case of a connection on a pressure regulator or gas
appliance which relies upon a sealing washer to maintain a
gastight joint, it is essential to check that the washer is present
and that it is sound and correctly positioned prior to making the
connection. Where the connection relies on a metal-to-metal
seating or bullnose connection to obtain a gastight joint, it is
essential that the mating surfaces be clean and undamaged.
Under no circumstances 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,
connection should be made in accordance with the manufacturer's
instructions and tools should not be used.
i.
If the continuation of supply is interrupted when a cylinder is
changed, it is essential that all appliance taps are turned off before
the change is made.
j.
With bulk storage tanks always ensure that the site is kept clean
and clear of rubbish. Such vessels are designed to be filled on
site by the gas distributors.
