4.3 Flue Hole Cutting
Mark out the flue centre, see diagram 4.2, then cut a hole for the
flue using, preferably, a 115mm minimum core drill.
4.4 Rear Flue Option Kit - 425861 (if applicable)
Fit the wall cover plates as described in the instructions supplied
with the kit.
4.5 Flue Preparation
Note: If the flue collar kit, see diagram 4.4, is to be used
increase the 15mm projection to 30mm.
Extend the 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
4.1.
If it is necessary to cut the flue ensure that the overlap is as
stated in diagram 4.1.
Carefully drill though air duct pilot hole and secure with self
tapping screw provided in fittings pack, see diagram 4.3.
Seal the joint with the tape provided.
Note: Should any one of the flue sections require cutting to
obtain desired flue system length make sure that the overlaps
are as follows:-
The overlap for air duct = 25mm
The overlap for flue duct = 50mm.
Take the terminal restrictor and position the clamping bracket
making sure the clamping bracket nib protrudes in the slot of the
terminal restrictor and secure with locking screw, but do not
tighten, see diagram 4.5.
Engage the terminal restrictor on the flue terminal by hooking it
over the terminal end and engaging the clamping bracket
behind the inner ring of the terminal securing it by tightening the
locking screw, see diagram 4.5.

Fit the self adhesive foam seal provided in the flue pack around
the air duct at the position shown in diagram 4.6.
Make sure that the ductings do not slope down towards the
boiler.
Make good around the flue outside after installation of the boiler.
Important: If the wall liner kit is used, the self adhesive foam seal
included in the wall liner kit must be used in place of the one
supplied with the flue pack, see diagram 4.6 for position of self
adhesive seal.
Push the flue assembly into and through the hole such that it is
within the wall, and does not stick out into the room. Do not push
the flue assembly too far into the hole as it has to be pulled back
into the boiler and secured.
If the boiler is not to be fitted for some time cover the hole in the
wall.
