Disconnect and remove the flue from the existing boiler by
undoing the four screws securing the appliance bend to the top
of the boiler (Fig.4)
5.
Ensure that all pipe connections are free, move
the base of the boiler forward and lift the boiler
off the hanging bracket tabs and unscrew the
hanging bracket from the wall. (Fig.5)
6.
Finally, check that the wall surface is sound, flat and capable of supporting the weight of the
boiler. Make any necessary repairs before installing the new boiler.
7.
It is suggested that where possible the existing pipe-
work is cut back approximately 200mm - 300mm for
ease of connecting the existing pipe-work to the new
valves (Fig. 6)
If a stand-off bracket has been used and the pipe-work runs
behind the boiler, then a new stand-off bracket will need to
be fitted and pipes extended to the new valve positions
(see below; paragraph 3-Fig.5)
