FOR MAXIMUM AND MINIMUM FLUE RUNS
.
Where it is not possible to terminate the flue within the
distance permitted for coaxial flues, the twin flue pipe can
be used by fitting a special adaptor to the flue connector
and using the aperture for the air intake located on top of
the combustion chamber.
Always ensure that the flue is adequately supported, using
one flue bracket per extension and avoiding low points.
(MTS supply suitable clamps as Part No. 705778).
To utilise the exhaust manifold it is necessary to connect
the adaptor (Part No: 3318017) to the exhaust manifold
and secure with the clamp (see F
IG
. 2.18A), add elbows or
extensions as required.
To utilise the air intake it is necessary to:
Remove the ‘knockout’ of the air intake by cutting it with a
suitable knife (F
IG
. 2.18B).
Insert the elbow/flue pipe into the air intake until it stops.

roof (see Fig. 2.16 for distance from the 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. 2.17)
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 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.
