Boiler Fixing
Having previously secured the wall mounting jig and hanging
bracket to the wall, lift the boiler into position in the following
manner. To assist in the lifting of the boiler, remove the front
panel.
Lean the top of the boiler slightly to the wall and position just
above the hanging bracket. Allow the boiler to slowly move
downwards until engaged in the hanging bracket.
Slowly swing the base of the boiler to the wall mounting jig
ensuring that the copper tails on the boiler fit into the gas and
water isolation valves on the jig, see diagram 8.1. If necessary
the gas and water isolation valve clamps can be loosened to
ease fitting. Make sure that the isolation valves are secured
with the clamps after making good the connections.
Connect the two electrical connector plugs hanging from the
boiler into the sockets on the wall mounting jig. The white mains
electrical supply socket on the left hand side of the jig and the
black auxiliary electrical socket on the right hand side of the jig.
Please refer to condensate connection before proceeding,
see section 9.4.
Attach the flue as described in section 7.6.
