FITTING THE FLUE
The top flue outlet permits both horizontal and
vertical flue applications to be considered,
alternatively, the Vokera twin flue system can be
utilised if longer flue runs are required.
4.5.1
CONCENTRIC HORIZONTAL FLUE
(For concentric vertical flue, see 4.5.2).
(For twin flue applications, see 4.5.3).
The appliance flue outlet elbow can be rotated
through 360
°
on its vertical axis. In addition the
flue may be extended from the outlet elbow in the
horizontal plane (see 2.9). A reduction must also
be made to the maximum length (see table below)
when additional bends are used.
Using the template provided (see fig. 6), mark
and drill a 125mm hole for the passage of the
flue pipe. The hole should have a 1
°
rise from the
boiler to outside.
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.

Take the large black gasket - supplied with the
flue terminal kit - and stretch it over the appliance
flue outlet (fig. 7). Using a twisting motion, connect
the boiler top adaptor - supplied with the flue
terminal kit - to the appliance flue outlet ensuring
the male spigot of the adaptor is pushed fully into
the flue outlet spigot of the boiler (fig. 7). 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.
Pass the concentric flue pipe through the
previously drilled hole. Fit the flue bend to the boiler
top adaptor and insert the concentric flue pipe into
the flue bend ensuring the correct seal is made.
NOTE
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.
