11.1 Unpacking
Check the contents against the packing list.
Remove the wall mounting template and the
manifold/mounting plate assembly.
11.2 Site Preparation
Check that the correct position for the appliance has been
chosen and that the wall is sound, flat and will support the
weight of the appliance. Refer to Sections 4 & 5 and Tables 4
and 8.
11.3 Fixing Holes and Flue Opening
If it is necessary for any of the pipes to run up the back of the
appliance then the, optional extra, space frame must be fitted to
the wall.
Hold the template to the wall. Check that the template is level.
Mark the position of the fixing holes and the flue opening. Refer
to Fig 15.
Drill the fixing holes 60mm deep for the No. 12 size plugs.
Cut the flue duct hole at 110mm diameter [150mm diameter for
internally fitted flues].
11.4 Wall Mounting Plate and Manifold
Fit the plugs and fix the mounting plate and manifold assembly
to the wall. Refer to Fig 15.
11.5 Gas and Water Pipes
Fix the appropriate fitting to the gas cock to connect the inlet

It is important that the system pipes are not fixed near the
appliance using clips that put a strain on the connections.
Before the appliance is connected to the wall manifold
thoroughly flush the system.
11.6 Install the Boiler
