5.5 FITTING THE FLUE
This appliance incorporates a ‘click-fit’ flue connection at the
top of the appliance.
5.5.1 CONCENTRIC HORIZONTAL FLUE
These instructions relate specifically to the installation of this
appliance with the Vokera 60/100mm ‘X-type’ (click-fit) flue
terminals and accessories. For specific instructions on installing
this appliance with an alternative Vokera flue system, e.g.
80/125mm; please refer to the instructions supplied with the
specific flue system, or download the instructions from the Vokera
website. The appliance flue outlet elbow can be rotated through
360º on its vertical axis. In addition the flue may be extended
from the outlet elbow in the horizontal plane (see section 2.9).
A reduction must also be made to the maximum length (see
table below) when additional bends are used.

Using the template provided (
A
), mark and drill a 125mm hole
for the passage of the flue pipe. Each horizontal terminal,
incorporates an incline on the inner (60mm) pipe; this enables
the terminal to be installed on a level plane. However any
extended horizontal flue runs must incorporate a 3-degree fall-
back from the flue terminal towards the appliance. 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.

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 65mm to dimension X to give you Dimension Y (see fig. 12).
Measure dimension Y from the terminal end of the concentric
flue pipe and cut off the excess ensuring any burrs are removed.
IMPORTANT:
The X-type flue terminals are supplied with
a sachet of silicone lubricant; smear a small amount of the
lubricant around both inner and outer connections, at both
ends of the flue bend.
NOTE:
Attach the decorative white plastic trim to the flue pipe
at this point if it’s required.
Attach the flue bend to the flue terminal ensuring that both pipes
are fully inserted into the flue bend. Insert the assembled flue
terminal and bend into the pre-drilled hole and offer up the flue
bend to the appliance flue spigot.
NOTE - fig. 11:
the appliance incorporates a ‘click-fit’ flue
connection. Ensure that both screws ‘
C
’ on the ‘click-fit’ have
been slackened off. Ensure that the bend is correctly aligned
with the connector and insert the flue bend into the connector
until it clicks into position (this is when the tabs at points ‘
A
’ are
located in the groove of the flue bend. Both screws (
C
) should
now be tightened.
NOTE:
if more convenient, the flue bend can be attached to the
appliance before connecting it to the flue terminal.
NOTE:
ensure that the outlet of the flue terminal is correctly
orientated as shown in fig. 12.
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 exterior trim can now be fitted.
