tighten service cock bracket (lower jig) fixing screws. It is
important that the wall hanging bracket and the service cock
bracket(lowerjig)arefittedtoaflatandtruewallareaforcorrect
alignment with the boiler. If this cannot be achieved it is
acceptable to pack out the service cock bracket (lower jig) to
obtain the correct alignment with the wall hanging bracket.
6.2 Gas Connection
Provision is made for the gas supply to be connected from
below the boiler, see diagrams 1.1 and 6.1 for position.
