INSTALLATION
Fitting the Coaxial Flue
(Ø 60 / 100 Vertical)
Note: See table for maximum and minimum flue runs.
Contents:
1x Conical Adaptor (60/100mm)
1x Vertical Flue Kit (80/125mm)
The vertical flue kit is supplied with a specially designed weather
proof terminal fitted, it can be used either with a flat roof or a
pitched roof.
The Vertical flue kits useable lengths with the pitched roof flashings
are indicated in Fig. 7.
Before proceeding to fit the flue, ensure that the maximum flue
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 flue length,
and for each 45° 0.5 metres must be subtracted from the total flue
length (the height of the vertical adaptor and a 45° bend can be
seen in Fig. 8).
Mark the position of the flue hole in the ceiling and/or roof (see Fig.
7 for distance from wall to the centre of the flue).
Cut a 130mm diameter hole through the ceiling and/or roof and fit
the flashing plate to the roof.
DO NOT cut the vertical flue kit.
To connect the vertical flue 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, fit 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 fit connection), the vertical flue kit must then be inserted
through the roof flashing, this will ensure that the correct clearance
above the roof is provided as the terminal is a fixed 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 flue kit to be fitted. 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 flue remain flush.
When utilising the vertical flue system, action must be taken to
ensure that the flue is supported adequately to prevent the weight
being transferred to the appliance flue connection by using 1 flue
bracket per extension.
When the flue passes through a ceiling or wooden floor, there must
be an air gap of 25mm between any part of the flue system and any
combustible material. The use of a ceiling plate will facilitate this.
Also when the flue passes from one room to another a fire stop must
be fitted to prevent the passage of smoke or fire, irrespective of the
structural material through which the flue passes.
