EXTENDING THE FLUE
Connect the bend – supplied with the terminal kit – to the top
of the boiler using clamp (supplied) see fi g. 10. The additional
bends & extensions have push-fi t connections, care should be
taken to ensure that the correct seal is made when assembling
the fl ue system. Connect the required number of fl ue exten-
sions or bends (up to the maximum equivalent fl ue length) to
the fl ue terminal (see fi g. 10-12).
The fl ue system should have
a minimum of 1º; maximum of 3º rise from the boiler to outside,
to ensure any condense fl uid 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 exten-
sion. Remove any burrs, and check that all seals are located
properly. You must ensure that the entire fl ue system is properly
supported and connected. Seal the fl ue assembly to the wall us-
ing cement or a suitable alternative that will provide satisfactory
weatherproofi ng. The interior and exterior trim can now be fi tted.

g. 13) (rear
fl
ue outlet
only)
Using the template provided, mark and drill a 125mm hole
for the passage of the fl ue pipe, see fi g 9. The hole should
be drilled LEVEL to ensure any condense fl uid that forms, is
allowed to drain back to the appliance. The fi xing holes for
the wall mounting bracket should now be drilled and plugged,
an appropriate type and quantity of fi xing should be used to
ensure that the bracket is mounted securely. Once the bra-
cket has been secured to the wall, remove the blanking plate
from the rear of the boiler (Fig. 15).
NOTE The inner 60mm pipe of the rear fl ue terminal mu
st be
cut by 12mm at the point indicated (
