3.5 Gas supply

The gas supplier should ensure the availability of an

adequate supply of gas. A gas meter may only be con-

nected to the service pipe by the supplier of gas or their

contractor. An existing meter should be checked to

ensure that it is capable of passing the rate of gas sup-

ply required.

Installation pipes should be fitted in accordance with

BS 6891. In IE the current edition of IS 813. Pipework

from the meter to the boiler must be of an adequate

size. Do not use pipes of a smaller size than the boiler

gas connection (15 mm). The complete installation must

be checked for leaks and purged as described in

BS 6891.
