4.6 Wall Mounting Bracket
Reposition the template, making sure of dimensional alignment
with the flue hole.
Mark the boiler fixing points and mounting bracket position, see
diagram 4.4.
NOTE:
the mounting bracket has additional holes to allow for
further fixings should site conditions require it.
Drill holes and plug, to suit No.12x2in woodscrews, fit the
screws allowing sufficient clearance, about 5mm, to accept the
swing brackets, see diagram 4.4.
Secure the mounting bracket to the wall with No.12x2in
woodscrews and plugs, see diagram 4.4.
If the boiler is not to be fitted for some time, cover the hole in the
wall.
4.7 Flue Length
For a rear flue, measure the distance from the outside wall face
to the boiler mounting wall. Check that the flue length will be
suitable, see diagram 4.2.
For a side flue, measure the distance from the outside wall face
to the boiler centre line. Check that the flue length will be
suitable, see diagram 4.3.
Extend the standard telescopic flue to the required length,
making sure that the minimum overlap is no less than 25mm,
and that the flue terminal projects 15mm minimum beyond wall
face, see diagram 4.5.
Carefully drill though the hole at the side of the flue, secure with
self tapping screw, see diagram 4.6.
Seal the joint with the provided tape.
All 1, 2 and 3 metre flue systems are installed in a similar manner
to the standard telescopic flue.
NOTE:
Should any one of the 1, 2, or 3 metre flue systems
require cutting to obtain desired flue system length, do not cut
at the pre-drilled end. The standard telescopic flue is not pre-
drilled.
Make sure to cut square and remove any burrs.
If the boiler is not to be fitted for some time cover the hole in the
wall.

4.8 Rear Flue
Mark the air duct/terminal assembly and the flue duct at the
length shown in diagram 4.5 then cut to length.
NOTE:
Owing to its variable length the standard telescopic flue
may not need cutting.
