5.4 Mounting the appliance
The appliance should be mounted on a smooth,
vertical surface, which must be capable of
supporting the full weight of the appliance. Care
should be exercised when determining the
position of the appliance with respect to hidden
obstructions such as pipes, cables, etc.
When the position of the appliance has been
decided – using the template supplied – carefully
mark the position of the fixing jig/mounting bracket
assembly (see fig. 7) and flue-hole (if applicable).
5.4.1 Important
There are two holes on the template. The lower
hole should be used with the telescopic flue kit
(part no. 0225705 & 0225710). The upper hole is
for use with all other horizontal flue kits.
5.4.2 Maximum flue lengths
5.5 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.
5.5.1 Concentric horizontal flue
(For concentric vertical flue, see 5.5.2)
(For twin flue applications, see 5.5.3)
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 5.4.2), however if the
flue is to be extended or additional bends are
to be fitted, the standard horizontal flue kit
(part no. 2359029) must be used. A reduction
must also be made to the maximum length
(see table) when additional bends are used.
U sing the template provided (see 5.4.1), mark
and drill a 125mm hole for the passage of the flue
pipe. The hole should have a 1º drop from the
boiler to outside, to eliminate the possibility of
rainwater entering the appliance via the flue.
The fixing holes for the wall-mounting bracket &
jig 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 & jig has been secured to the
wall, mount the appliance onto the bracket.

FITTING THE TELESCOPIC FLUE KIT (0225705 &
0225710)
Carefully measure the distance from the centre of the
appliance flue outlet to the face of the outside wall
(dimension ‘X’ see fig. 12). Add 50mm to dimension ‘X’
to give the overall flue length (dimension ‘Y’). Using the
complete telescopic flue assembly adjust the length to
suit dimension ‘Y’. Once the telescopic flue terminal
has been adjusted to the correct length, secure the flue
assembly with the screw supplied.
NOTE
The flue restrictor ring (see fig. 1) must be removed or
discarded prior to attaching the flue bend to the appliance.
Insert the flue assembly into the previously drilled flue
hole and locate the flue bend over the appliance flue
outlet. Push the flue bend down over the appliance flue
outlet and ensure the correct seal is made. Pull the flue
assembly towards and over the flue bend – using a
twisting action – ensuring the correct seal is made.
Check that the terminal protrudes past the finished
outside wall by the correct length (115mm).
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
