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. 2.16.
Before proceeding to fit the flue, ensure that the maximum
flue length has not been exceeded (See the tables on Page
19) and that all elbows and bends have been taken into
consideration, the maximum flue length is 4 metres, for each
additional 90
o
elbow 1 metre must be subtracted from the
total flue length, and for each 45
o
0.5 metres must be
subtracted from the total flue length (the height of the
vertical adaptor and a 45
o
bend can be seen in Fig. 2.17).
Mark the position of the flue hole in the ceiling and/or roof
(see Fig. 2.15 for distance from wall to the centre of the flue).
Cut a 120mm 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. 2.16) 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 (Fig.
2.12)
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.
