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 at least 1.5°.
2. When completed the terminal must be at least 2
metres above ground level (Fig. 7).
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.
7a, 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 at
least 1.5° 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.
7c) 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. 7b.
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. 7d. 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. 7e).
