4.2 Fitting the Coaxial Flue (
Ø
60/100 Vertical) Continued/......
4.3 Fitting the Coaxial Flue (
Ø
80/125 Horizontal / Vertical)
NOTE:SEE PAGE 18 FOR MAXIMUM AND MINIMUM FLUE RUNS.
Once the boiler has been positioned on the wall, for hor-
iz
ontal flue runs, insert the Ø60/100 elbow onto the boil-
er, and connect the elbow to the Ø80/125 adaptor, for
vertical flue runs it is necessary to insert the Ø80/125
adaptor (
FIG.17) (not supplied with flue kit - Part No
3318040
) into the boiler flue socket.
Push the adaptor onto the boilers flue connection,
grease the seals then add extensions or elbows as
required, secure the adaptor, using the clamp and
screws provided.
To fit extensions or elbows it is first necessary to ensure
that the lip seal is fitted correctly into the inner flue, once
verified, it is simply necessary to push them together, no
clamps are necessary to secure the flue components.
Before proceeding to fit the flue, ensure that the maxi-
mum flue length has not been exceeded (See the tables
on Page 18) and that all elbows and bends ha
v
e been
tak
en into consider
ation, the maxim
um flue length is 6
metres
, f
or each additional 90
o
elbo
w 1 metre m
ust be
subtracted from the total flue length, and for each 45
o
0.5 metres m
ust be subtr
acted from the total flue length
(the height of the ver
tical adaptor and a 45
o
bend
can be seen in Fig.
18 and a 90
o
bend in Fig.
19)

OTE: DO NOT CUT THE VERTICAL FLUE KIT.

DO NOT cut the vertical flue kit.
T
o connect the vertical flue kit directly to the boiler, place the
vertical starter kit
(Part No. 3318008) (see Fig. 15) onto the
e
xhaust manifold and secure with the clamp, fit the
Ø125/100 adaptor onto the vertical starter kit (note: there is
n
o need to use a clamp to secure this as it is a push fit con-
nection), the vertical flue kit must then be inserted through
the roof flashing from the outside, this will ensure that the
correct clearance above the roof is provided as the terminal
i
s a fixed height.
Should extensions be required, they are available in 1 metre
(Part No. 3318005), 500mm (Part No. 3318006) and
250mm lengths (Part No. 3318007), they must be connect-
ed directly to the vertical starter kit before connecting the
a
daptor 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 dis-
tance between the inner and outer flue is maintained (
Fig.
14).
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 ceil-
ing 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 mate-
rial through which the flue passes.
