NOTE: READ THIS SECTION FULLY BEFORE COMMENCING THE
INSTALLATION.
11.1 General
The appliance is only suitable for fitting to a sealed system.
The flue must be installed as specified in BS5440:1 and the
current Building Regulations.
11.2 Unpacking
Remove the appliance from its packaging and check the contents
against the packing list.
Unscrew the service connections and remove the wall mounting
assembly.
NOTE:
The wall mounting assembly can be removed from the
carton
without
having to remove the boiler.
11.3 Site Preparation
Check that the correct position for the appliance has been
chosen. Refer to Section 4 and Table 8.
Check that the wall is flat and will support the weight of the
appliance. Refer to Table 4.
11.4 Fixing Holes and Flue Opening
Hold the wall mounting assembly or template against the wall.
Check that the assembly or template is level. Mark the position
of the fixing holes and the flue opening. Refer to Fig 16.
The diamond cut-out indicates the centreline of the appliance.
Mark the centrelines of the pipe connections to aid the pre-
plumbing of the system pipework.
Pre-plumbing is not recommended if no movement in the pipes
is available.
Check the position of the fixing points and flue opening before
drilling the fixing holes 60mm deep for the No. 12 size plugs and
cutting the flue duct hole at 110mm diameter [150mm diameter
for internally fitted flues].
11.5 Wall Mounting and Manifold Assembly
Fit the plugs and insert the bottom screws.
Check that all service valves are closed.
Offer the assembly to the wall utilising the keyhole slots on the
manifold assembly and fix to the wall. Refer to Fig 16 and 17.
Check that the assembly is properly aligned before tightening
the screws.
11.6 Gas and Water Pipes
Remove the gas cock and fix the appropriate fitting to connect
the inlet pipe and refit. Refer Fig 17.
If it is necessary for any of the pipes to run up the back of the
appliance then they must be arranged to pass behind the
expansion vessel. Refer to Fig 3. Pipework must not run
horizontally within the limits of the casing.
It is important that the pipes are not fixed near the appliance
using clips that put a strain on the connections.
Before the appliance is fitted to the wall thoroughly
flush the system and mains water supply.
