9.3 General Fitting Notes
1. Cut a hole in the external wall which the concentric flue
assembly will pass through. The hole should allow the flue
to fall back to the boiler at an angle of 1.5° to 3°.
2. When completed the terminal must be at least 2 metres
above ground level (Fig. 19).
3. Measure and cut to size the concentric assembly and any
extensions that are being used.
4. Insert the concentric assembly through the hole from
outside the building.
5. If required, the flexible flue trim should be fitted prior to
this as it cannot be fitted after. Use the large ‘Jubilee’ clip to
secure the trim to the flue (See Fig. 20, trim shown
dotted), with the screw part of the clip at the bottom.
6. Connect any extensions or elbows that are being used
to the concentric assembly. Engage the extension, elbow
or concentric assembly in the boiler flue elbow. Fit the
boiler flue elbow to the boiler adaptor.
7. Ensure that the concentric assembly and any extensions
fall back to the boiler at an angle of 3° and that the
external air inlet is to the bottom.
8. Use suitable brackets to support the concentric
assembly and any extensions, and make good inside and
outside.
9. The 60Ø exhaust can now be fitted. Slide the adaptor
over the plain end of the 60Ø exhaust (Fig. 22) and engage
the exhaust in the terminal. Slide the adaptor down over
the spigot. Mark and drill the adaptor, using a 2mm bit, as
shown in Fig. 21. Secure the adaptor to the spigot using
one of the screws supplied.
10. If it is necessary to shorten the 60Ø exhaust or any of
the extensions, the excess material must be cut from the
plain end of the pipe.
11. Determine the position of the 60Ø exhaust and mark
on the wall a suitable position for the support bracket. If
extensions are being used, a support bracket is supplied in
each kit.
12. Drill the wall, and fit the bracket(s) using the plug and
screw provided.
13. Mark and drill the 60Ø exhaust, using a 2mm bit, as
shown in Fig. 23. Complete the installation of the 60Ø
exhaust, securing in the brackets.
14. Fit the 93° elbow/plume outlet and secure with the
two remaining screws supplied. Ensure the plume outlet is
at least 45° to the wall and that the ‘peak’ is uppermost
(Fig. 24).
