3.3 Gas supply
The gas supplier should ensure the
availability of an adequate supply of
gas.
A gas meter may only be connected
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 supply required.
Installation pipes should be fitted in
accordance with BS 6891.
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
tested for soundness and purged as
described in BS 6891.
3.4 Flue system
The standard horizontal flue system
(Art. No. 300 807) is suitable for
installations up to 995 mm measured
from the centre of the boiler flue outlet
to the outside face of the wall (A, fig.

are available to extend this length up
to 2965 mm. Both 90° elbows
(Art. No. 300 808) and 45° bends
(Art. No. 300 809) are also available
to increase siting flexibility.
A vertical flue system is also available
(Art. No. 300 800).
