GAS SAFETY
Gas safety (Installation and Use) Regulations, 1994
amendments 1996 or rules in force.
It is law that
all
gas appliances are installed by a CORGI
registered installer (identified by
) in accordance with the
above regulations. Failure to install appliances correctly could
lead to prosecution. It is in your own interest, and that of safety,
to ensure the law is complied with.
The installation of the boiler MUST also be in accordance with
the latest I.E.E. (BS 7671) Wiring Regulations, local building
regulations, bylaws of the local water authority, the Building
Regulations and Building Standards (Scotland) and any relevant
requirements of the local authority.
Detailed recommendations are contained in the following British
Standard Codes of Practice:
BS. 6891
Low pressure installation pipes.
BS. 6798
Installation of gas fired hot water boilers of rated
input not exceeding 60 kW.

IMPORTANT.
These appliances are certificated by the British
Standards Institution for safety and performance. It is important,
therefore, that no external control devices, e.g. flue dampers,
economisers etc., are directly connected to these appliances
unless covered by these Installation and Servicing Instructions
or otherwise recommended by
Caradon Plumbing Limited
in
writing. If in doubt please enquire.
Any direct connection of a control device not approved by
Caradon Plumbing Limited
could invalidate the BSI
Certification and the normal appliance warranty. It could also
infringe the Gas Safety Regulations and the above regulations
or other statutory requirements.
LOCATION OF BOILER
The boiler must be installed on a flat and level floor, capable of
adequately supporting the weight of the boiler and any ancillary
equipment.
The boiler may be fitted on a combustible floor.
Insulation is not necessary, unless required by the local
authority.
The boiler must not be fitted outside.
The boiler must not be installed in a bedroom or in a room
containing a bath or shower.
Timber Framed Buildings
If the boiler is to be fitted in a timber framed building it should be
fitted in accordance with the Institute of Gas Engineering
document IGE/UP/7:1998.
Compartment Installations
A compartment used to enclose the boiler MUST be designed
and constructed specially for this purpose.
An existing cupboard or compartment may be used, providing it
is modified for the purpose.
Details of essential features of cupboards /compartment design,
including airing cupboard installation, are to conform to the

For the minimum clearances required for safety, and
subsequent service, see Frame 2.
GAS SUPPLY
The local gas supplier should be consulted, at the installation
planning stage, in order to establish the availability of an
adequate supply of gas. An existing service pipe must NOT be
used without prior consultation with the local gas supplier.
The boiler is to be installed only on a gas supply with a
governed meter.
A gas meter can only be connected by the local gas supplier or
by a local regional contractor.
Check that the appliance is suitable for the proposed gas supply.
An existing meter should be checked, preferably by the gas
supplier, to ensure that the meter is adequate to deal with the
rate of gas supply required. A
minimum
gas pressure of 20
mbar MUST be available at the boiler inlet, with the boiler
operating.
Installation pipes MUST be fitted in accordance with BS. 6891.
Pipework from the meter to the boiler MUST be of an adequate
size.
The complete installation MUST be tested for gas soundness
and purged as described in the above code.
