Effect of an extract fan
If there is type of extract fan fitted in the premises, there is the possibility with open flued appliances, that if inadequate
fresh air vents are not provided, spillage of products from the flue diverter could take place, when the fan is in operation.
Where such installations are found, a test for spillage must be carried out as described in Part. 1 of BS 5440, and the
necessary action taken.
Gas Supply
If necessary the local Gas Region should be consulted, at the installation planning stage, in order to establish the
availability of an adequate supply of gas.
An existing service pipe must not be used without prior consultation with the Local Gas Region.
A gas meter can only be connected by the Local Gas Region, or by a Local Gas Region's Contractor.
Installation pipes should be fitted in accordance with BS6891-1988.
Pipework from the meter to the combination boiler must be of an adequate size.
The boiler requires 2.72 m
3
/h of natural gas.
WE REQUIRE 22 mm PIPE FROM THE METER TO THE BOILER.
The complete installation must be tested for gas soundness and purged as described in BS6891-1988. All pipework must be
adequately supported. An isolating gas valve is provided and should be fitted on manifold assembly.
