The exhaust gas ducts must not be in contact with or close
to infl ammable material and must not pass through building
structures or walls made of infl ammable material.
When replacing an old appliance, the fl ue system must be
changed.
Important
Ensure that the fl ue is not blocked.
Ensure that the fl ue is supported and assembled in accordance

3.4.1 Fitting the Coaxial Flue
(Ø 60 / 100 Horizontal)
Contents:
1x Silicone O-Ring (60mm)
1x Elbow (90°)
2x Wall Seals (Internal & External)
1x Flue Pipe including Terminal (1 metre - 60/100)
2x Flue Clamps
4x Screws
2x Seals
Once the boiler has been positioned on the wall, fi t the rubber
fl ue seal into the internal fl ue turret (see diagram opposite),
insert the elbow into the socket and rotate to the required
position. note: It is possible to rotate the elbow 360° on its
vertical axis.
Using the fl ue clamp, seals and screws supplied (Fig 3.16)
secure the elbow to the boiler.
The 1 metre horizontal fl ue kit (3318073) supplied is suitable
for an exact X dimension of 753mm.
Measure the distance from the face of the external wall to the
face of the fl ue elbow (X - Fig 3.14), this fi gure must now be
subtracted from 753mm, you now have the total amount to be
cut from the plain end of the fl ue.
Draw a circle around the outer fl ue and cut the fl ue to the
required length taking care not to cut the inner fl ue, next cut
the inner fl ue ensuring that the length between the inner and
outer fl ue is maintained. (Fig 3.16).
e.g.
X = 555mm
753-555 = 198mm
(Length to be cut from the plain end of the fl ue).
Once cut to the required length, ensure that the fl ue is free
from burrs and reassemble the fl ue. If fi tting the fl ue from
inside of the building attach the grey outer wall seal to the
fl ue terminal and push the fl ue through the hole, once the
wall seal has passed through the hole, pull the fl ue back until
the seal is fl ush with the wall. Alternatively, the fl ue can be
installed from outside of the building, the grey outer seal
being fi tted last.
Should the fl ue require extending, the fl ue connections are
push fi t, however, one fl ue bracket should be used to secure
each metre of fl ue.
Note: See table for maximum and minimum fl ue runs.
