A gas meter can only be connected by the Local Gas supplier, or by a Local Gas suppliers Contractor.
Installation pipes should be fitted in accordance with BS6891-1988.
Appliance inlet working pressure must be 20mbar MINIMUM, for NG and 37 mbar minimum for LPG.
Pipework from the meter to the combination boiler must be of an adequate size.
The boiler requires 2.73m
Do not use pipes of a smaller size than the combination boiler inlet gas connection.
The complete installation must be tested for gas soundness and purged as described in BS6981-1988. All
pipework must be adequately supported. An isolating gas valve is provided and should be fitted on the boiler
gas inlet. Please wait 10 minutes when lighting from cold before checking gas rate. Gas pressures should be
checked after the boiler has operated for 10 minutes to reach thermal equilibrium.
