NOTE
When cutting the horizontal flue terminal or an
extension to the required length, you must ensure
that the excess is cut from the plain end of the
terminal or extension, and that the inner (60 mm)
pipe is 7.5 mm longer than outer (100 mm) pipe
(fig. 8A & 8B). Remove any burrs, and check that
any seals are located properly.
You must ensure that the entire flue system is
properly supported and connected.
Seal the flue assembly to the wall using cement
or a suitable alternative that will provide
satisfactory weatherproofing. The interior and
exterior trim can now be fitted.
4.5.2
CONCENTRIC VERTICAL FLUE
The vertical flue terminal can be connected directly
to the appliance flue outlet. Alternatively, an
extension or bend can be connected to the
appliance flue outlet if desired (see section 4.4.2),
however if additional bends are fitted, a reduction
must be made to the maximum flue length (see
table below).
Using the dimensions given in fig. 9 as a reference,
mark and cut a 105 mm hole in the ceiling and/or roof.

Fit the appropriate flashing plate to the roof and
insert the vertical flue terminal through the flashing
plate from the outside, ensuring that the collar on
the flue terminal fits over the flashing.
The fixing holes for the wall-mounting bracket
should now be drilled and plugged, an appropriate
type and quantity of fixing should be used to
ensure that the bracket is mounted securely.
Once the bracket has been secured to the wall,
mount the appliance onto the bracket.
IMPORTANT
The vertical flue terminal is 1.0 metre in length
and cannot be cut; therefore it may be necessary
to adjust the height of the appliance to suit or use
a suitable extension.
Insert the flue restrictor ring into the appliance flue
outlet, in accordance with the table in section 4.4.2.
Connect the vertical flue assembly to the boiler
flue spigot using the 60 mm & 100 mm clips,
gaskets, & screws (supplied), ensuring the correct
seal is made. The flue support bracket (supplied
with the vertical flue kit) can now be fitted.
If the vertical flue requires extension/s or additional
bend/s, connect the required number of flue
extensions or bends (up to the maximum
equivalent flue length) between the boiler and
vertical flue assembly (fig. 8B).
NOTE
When cutting an extension to the required length,
you must ensure that the excess is cut from the
plain end of the extension and that the inner (60
mm) pipe is 7.5 mm longer than outer (100 mm)
pipe (fig. 8B). Remove any burrs, and check that
any seals are located properly.
You must ensure that the entire flue system is
properly supported and connected.
