requirements of British Standards and Codes of Practice listed in Section 1 of this manual.
A gas meter will be connected to the service pipe by British Gas plc or it's authorised

The meter and service pipe should be checked by British Gas or it's authorised contractor

Fit the gas cock immediately upstream of the gas control valve using a suitable jointing
compound and connect to the gas supply. An inlet nipple and m/f elbow is factory fitted
to the gas control valve to avoid possible damage.
Where the water heater(s) is(are) installed in a boiler house or purpose built
compartment, a manually operated valve for the boiler house must be fitted in
accordance with the Gas Safety (Installation and Use) Regulations 1998. The valve must
be easily identified and readily accessible.
After installation, the system should be pressure tested for soundness and purged in
accordance with BS 6891 or IM/2 and IM/5 as appropriate.
