INSTALLING THE APPLIANCE FOR SIDE
FLUE OUTLET (Fig. 29)
5.7.1
- Attach the template to the wall with adhesive
tape, making sure that the centre line is
vertical and that the distance from the centre
line to the nearest side wall is not less than
measurement in Fig.29.
- Mark the two fixing bracket securing holes on
the wall and extend the axis of the flue duct
hole to the side wall ensuring it is horizontal.
-
Make sure flue slopes 2.5° down towards
the boiler that is 45 mm/m fall per metre
of the flue length.
- Trace the centre of the flue duct hole measure
distance . From the corner of the wall
(Fig. 29), measure the distance (127mm)
between the centre of flue duct hole to the
corner
Detach the template from wall.
- Use a dia. 10 mm. drill to make the 2 holes for
securing hanging Bracket fixing . Insert the
plastic expansion plugs. Core drill a 105 mm
dia. hole in the side wall for inserting the flue
duct.

5.7.2
Positioning the elbow towards the required
direction
.
5.7.3
Make sure that rubber seal Ø 60 is locate
into the elbow .
5.7.4
If using horizontal flue duct and it is too
long it can be shortened.
Should it be necessary to cut the flue
always.Cut equal amounts from both inner
and outer pipes.
Note
: add 30mm to overall flue length to
allow for cover plate.( Fig.12 item127). .
5.7.5
Insert the flue assembly into the wall, making
sure it will not interfere when fixing the boiler
on the wall.
5.7.6
Lift the boiler on the wall. Locate onto the
wall fixing bracket.
5.7.7
Working above the boiler pull the flue duct
towards the elbow in order to engage tube
into its header (Fig.12). Position flue into
straight header and push so as to locate inner
and outer flue correctly. Ensuring good seal is
made with o.rings.
5.7.8
IMPORTANT:
Terminal rubber must be fitted
(Fig. 12).
5.7.9
Extension kits are available see table 6.
- Remove the centering spring, pull the
flue terminal disengage inner flue duct.
- Measure the thickness W of the wall.
- Cut the outer air duct (100 mm. dia.) at right
angles and to a length equal to W+Y - 47
mm. (Fig. 32)
- Cut the inner flue duct (60 mm dia.) at right
angles and to a length equal to W+Y + 65 mm.
- Outer air duct and inner flue duct must be
de-burred.
- Reassemble the two tubes.
