EXTENDING THE FLUE
Connect the bend – supplied with the terminal kit – to the top
of the boiler using clamp (supplied) see fig. 11. The additional
bends & extensions have push-fit connections, care should be
taken to ensure that the correct seal is made when assembling
the flue system. Connect the required number of flue exten -
sions or bends (up to the maximum equivalent flue length) to
the flue terminal (see fig. 11-14). The flue system should have
a minimum of 1º; maximum of 3º rise from the boiler to outside,
to ensure any condense fluid that forms, is allowed to drain
back to the appliance.
NOTE
When cutting an extension to the required length, you must
ensure that the excess is cut from the plain end of the extension
(see fig. 11-14). Remove any burrs, and check that all 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.

4.5.1.2 FITTING THE REAR FLUE (fig. 15) (rear flue outlet
only)
Using the template provided, mark and drill a 125mm hole
for the passage of the flue pipe. The hole should be drilled
LEVEL to ensure any condense fluid that forms, is allowed
to drain back to the appliance. The fixing holes for the wall-
mounting bracket should now be drilled and plugged, an ap-
propriate 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, attach the rear flue terminal to the
appliance (using the previously retained screws) and fix the
telescopic terminal to the correct length (wall thickness) en-
suring that the terminal will protrude through the wall by the
correct distance. At this point, lift the appliance and carefully
insert the terminal into and through the wall, ensuring that the
holes in the appliance back frame are aligned with the studs
on the wall bracket.

Using the screws and washers provided, secure the appliance
onto the wall bracket and tighten with a suitable spanner.
Seal the flue assembly to the wall using cement or a suitable
alternative that will provide satisfactory weatherproofing. The
exterior wall trim can now be fitted.
