Using the screws and washers provided, secure the ap-
pliance onto the wall bracket and tighten with a suitable
spanner.
Seal the fl ue assembly to the wall using cement or a suitable
alternative that will provide satisfactory weatherproofi ng.
The exterior wall trim can now be fi tted.
4.5.2 CONCENTRIC VERTICAL FLUE
The appliance can be used with either the Vokera con-
densing 60/100mm concentric fl ue system or the optional
80/125mm concentric fl ue system.
NOTE
These instructions relate
only
to the Vokera condensing
60/100mm concentric fl ue system. For specifi c details on
the installation of the 80/125mm concentric fl ue system
please refer to the instructions supplied.
The vertical fl ue terminal can be connected directly to
the appliance fl ue outlet. Alternatively, an extension or
bend can be connected to the appliance fl ue outlet if
desired (see 4.4.2), however if additional bends are fi tted,
a reduction must be made to the maximum fl ue length
(see table below).

Using the dimensions given in fi g. 12 as a reference, mark
and cut a 115mm hole in the ceiling and/or roof.

“X”= 139 mm
Fit the appropriate fl ashing plate to the roof and insert
the vertical fl ue terminal through the fl ashing plate from
the outside, ensuring that the collar on the fl ue terminal
fi ts over the fl ashing.
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 bracket has been secured
to the wall, mount the appliance onto the bracket.
IMPORTANT
The vertical fl ue terminal is 1.0 metre in length and can-
not be cut; therefore it may be necessary to adjust the
height of the appliance to suit or use a suitable extension.
Connect the vertical fl ue assembly to the boiler fl ue spigot
using the 100mm clip, gasket & screws (supplied), en-
suring the correct seal is made. The fl ue support bracket
(supplied with the vertical fl ue kit) can now be fi tted.
If the vertical fl ue requires extension/s or additional bend/s,
connect the required number of fl ue extensions or bends
(up to the maximum equivalent fl ue length) between the
boiler and vertical fl ue assembly (see fi g. 8).
Ensure that any horizontal sections of the fl ue system
have a minimum 1º; maximum 3º fall back to the boiler
(1º = 17mm per 1000mm).
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 fi g. 8). Remove any burrs, and check
that any seals are located properly.
You must ensure that the entire fl ue system is properly
supported and connected.
