Warning
The exhaust gas ducts must not be in contact with or close to inammable material and must not pass throu-
gh building structures or walls made of inammable material.
When replacing an old appliance, the ue system must be changed.
Important
Ensure that the ue is not blocked.
Ensure that the ue is supported and assembled in accordance with these instructions.

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, t
the rubber ue seal into the internal 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 ue clamp, seals and screws supplied (Fig
4) secure the elbow to the boiler.
The 1 metre horizontal ue kit (3318073) supplied is
suitable for an exact X dimension of 811mm.
Measure the distance from the face of the external
wall to the face of the ue elbow (X - Fig 2), this
gure must now be subtracted from 811mm, you
now have the total amount to be cut from the plain
end of the ue.
Draw a circle around the outer ue and cut the ue
to the required length taking care not to cut the
inner ue, next cut the inner ue ensuring that the
length between the inner and outer ue is maintai-
ned. (Fig 4).
e.g.
X = 555mm
811-555 = 256mm (Length to be cut from the
plain end of the ue).
Once cut to the required length, ensure that the ue
is free from burrs and reassemble the ue. If tting
the ue from the inside of the building attach the
grey outer wall seal to the ue terminal and push
the ue through the hole, once the wall seal has
passed through the hole, pull the ue back until the
seal is ush with the wall. Alternatively, the ue can
be installed from the outside of the building, the
grey outer seal being tted last.
Should the ue require extending, the ue connec-
tions are push t, however, one ue bracket should
be used to secure each metre of ue.
Note: See table for maximum and minimum ue
runs.
During use it is possible small quantities of con-
densate will drip from the end of the terminal. Pay
attention when siting the ue termination point.
Applies to all horizontal terminations.
