8.1 Fixing jig, refer to diagram 7.1
• Note: It is important the hanging bracket and service cock
bracket are fitted to a flat and true wall area for correct alignment
with the boiler. If this cannot be achieved it is acceptable to pack
out the service cock bracket to obtain the correct alignment.
• Remove the contents of the fixing jig pack.
• Secure the left and right hand support brackets to the isolating
valve plate with the securing screws (2 OFF) supplied.
• Connect the copper connections and sealing washers to the
isolating valves.

2 Hot water system connections - Pipe diam. 15mm (F30E
Only)
3 Gas connection - Pipe diam. 15mm
8.2 Cutting the flue hole
• Remove the wall template, follow the instructions given on the
wall template.
• Determine the flue application, length and terminal position
before starting. NOTE: If you have choosen a standard rear flue
application the flue and adapter must be fitted before the boiler
is hung onto the wall.
• Position the wall template, taking due regard of the minimum
clearances for the selected flue application, see diagram 8.1.
• Rear hole cutting
Mark correct position of Rear or Top Rear flue outlet hole from
template.
• Side hole cutting
Mark the horizontal centre line for the hole on the rear wall.
Extend the horizontal centre line to the side wall and mark the
vertical centre line of flue hole as shown in diagram 8.1.
• Making allowance for the slope of the flue, cut hole in external
wall, preferably using a core drill. For installations with internal
and external access use a 105 mm diameter core drill.
For installations with internal access only use a 125 mm
diameter core drill.
Important
When cutting the flue hole and when extending the flue centre
line to a side wall, remember that the flue system must have a
fall of about 35 mm per metre of flue DOWNWARD towards the
terminal. There must NEVER be a downward incline towards
the boiler.
• Reposition the wall template over hole in wall.
• Mark the hanging bracket and jig position holes.
• Drill, plug and fix the hanging bracket to the wall using suitable
screws (not supplied).
• Check that the hanging bracket is level.
• Drill plug and fix the fixing jig to the wall.

8.3 Water connection
Connect the system pipework to the copper connections on the
fixing jig observing the correct flow and return format as shown
in diagram 3.1. Do not subject the isolating valves to heat.
8.4 Gas connection
• The supply from the governed gas meter must be of adequate
size to provide a constant inlet working pressure of 20 mbar (8
in w.g.).
To avoid low gas pressure problems, it is recommended that the
15 mm gas supply on the boiler is connected to using 22 mm
pipe (as close as possible to the boiler within 1 metre).
• On completion, the gas installation must be tested using the
pressure drop method and purged in accordance with the
current issue of BS6891.
Gas Safety (Installation and use) Regulations
In your interests and that of gas safety, it is the law that ALL gas
