5.3 Flue Hole Cutting
Having marked out the flue centre cut a hole for the flue see
diagram 5.5 for minimum core drill size for various wall
thicknesses.
This will allow for the 35mm per metre (2 o ) fall towards the boiler.
Note: If required, an optional Wall Liner Kit, part No.900862, is
available, complete with fixing instructions.
5.4 Wall Mounting Bracket
Reposition the template, making sure of dimensional alignment
with the flue centre lines
Mark the boiler securing screws and mounting plate position,
see diagram 5.6.
Drill holes and plug, fit the securing screws allowing sufficient
clearance to accept the keyhole fixing brackets and secure the
boiler mounting bracket to the wall.
