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, the
maximum flue length is see table, 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 160mm lengths,
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 wei-
ght 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 5mm between any part of the flue system
and any combustible material. The use of a ceiling plate will faci-
litate 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.
