Gas supply

The Gas meter is connected to the service pipe by the local gas region or a local gas region
contractor.
If the gas supply for the boiler serves other appliances ensure that an adequate supply is avail-
able both to the boiler and the other appliance when they are in use at the same time.
Pipework must be of adequate size. Pipes of a smaller size than the boiler inlet connection should
not be used.
Installation pipes should be fitted in accordance with BS 6891 and the complete installation
should be tested for tightness.
For Ireland (IE), refer to I.S.813.2002.
