INSTALLATION
Fitting the Coaxial Flue
(Ø 60 / 100 Vertical)
Note: See table for maximum and minimum fl ue runs.
Contents:
1x Conical Adaptor (60/100mm)
1x Vertical Flue Kit (80/125mm)
The vertical fl ue kit is supplied with a specially designed
weather proof terminal fi tted, it can be used either with a fl at
roof or a pitched roof.
The Vertical fl ue kits useable lengths with the pitched roof
fl ashings are indicated in Fig. 7.
Before proceeding to fi t the fl ue, ensure that the maximum fl ue
length has not been exceeded (See the tables) and that all
elbows and bends have been taken into consideration, for each
additional 90° elbow 1 metre must be subtracted from the total
fl ue length, and for each 45° 0.5 metres must be subtracted from
the total fl ue length (the height of the vertical adaptor and a 45°
bend can be seen in Fig. 8).
Mark the position of the fl ue hole in the ceiling and/or roof (see
Fig. 7 for distance from wall to the centre of the fl ue).
Cut a 130mm diameter hole through the ceiling and/or roof and
fi t the fl ashing plate to the roof.
DO NOT cut the vertical fl ue kit.
To connect the vertical fl ue kit directly to the boiler, place the
vertical starter kit (Part No. 3318079) (see Fig. 7) onto the exhaust
manifold and secure with the clamp, fi t the vertical adaptor onto
the vertical starter kit (note: there is no need to use a clamp to
secure this as it is a push fi t connection), the vertical fl ue kit must
then be inserted through the roof fl ashing, this will ensure that
the correct clearance above the roof is provided as the terminal
is a fi xed height.
Should extensions be required, they are available in 1 metre
(Part No. 3318077), 500mm (Part No. 3318078) and they must be
connected directly to the vertical starter kit before connecting
the adaptor to allow the vertical fl ue kit to be fi tted. In the event
that extension pieces need to be shortened, they must only be
cut at the male end and it must be ensured that the inner and
outer fl ue remain fl ush.
When utilising the vertical fl ue system, action must be taken
to ensure that the fl ue is supported adequately to prevent the
weight being transferred to the appliance fl ue connection by
using 1 fl ue bracket per extension.
When the fl ue passes through a ceiling or wooden fl oor, there
must be an air gap of 25mm between any part of the fl ue
system and any combustible material. The use of a ceiling
plate will facilitate this. Also when the fl ue passes from one
room to another a fi re stop must be fi tted to prevent the passage
of smoke or
fi re, irrespective of the structural material through
which the fl ue passes.
