Using the template provided, mark and drill a
115mm hole for the passage of the flue pipe. The
hole should have a 1° rise from the boiler to
outside, to ensure any condense fluid that forms,
is allowed to drain back to the appliance.
The fixing holes for the wall-mounting bracket/
fixing jig should now be drilled and plugged, an
appropriate type and quantity of fixing should be
used to ensure that the bracket/jig is mounted
securely. Once the bracket/jig has been secured
to the wall, mount the appliance onto the bracket.
FITTING THE HORIZONTAL FLUE KIT
Carefully measure the distance from the centre
of the appliance flue outlet to the edge of the
finished outside wall (dimension X). Add 45mm
to dimension X to give you Dimension Y (see fig
7A). Measure dimension Y from the terminal end
of the concentric flue pipe and cut off the excess
ensuring any burrs are removed. Pass the
concentric flue pipe through the previously drilled
hole. Fit the flue bend to the boiler flue outlet
and insert the concentric flue pipe into the flue
bend ensuring the correct seal is made. Using
the clamp, gasket, and screws supplied, secure
the flue bend to the appliance flue spigot. The
60mm M & F adaptor (supplied with the flue kit)
should be discarded.
NOTE
Fit the internal trim to the flue assembly prior to
connecting the flue pipe to the bend.
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 exterior trim can now be fitted.
4.5.2.1 EXTENDING THE FLUE
Connect the bend – supplied with the terminal
kit – to the top of the boiler using clamp (supplied)
see fig. 7. 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 extensions or bends (up to the
maximum equivalent flue length) to the flue
terminal (see fig. 7 & 8).
The hole should have a 1° 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. 7 & 8).
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.
