NOTE
Please refer to 3 - 3E and use the appropriate PPE when
carrying out any of the actions or procedures contained within
this section.
4.1 PREPARATION FOR MOUNTING THE
APPLIANCE
The appliance should be mounted on a smooth, vertical sur-
face, 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 wall
mounting bracket (see Fig. 12
) and flue-hole (if applicable).

4.2 FITTING THE FLUE
This appliance incorporates a ‘click-fit’ flue connection at the top
of the appliance, and also incorporates a rear-flue connection.
Should the rear-flue connection be preferred, the flue outlet will
require to be re-configured from a top outlet to a rear outlet.
Please refer to section 4.6.1.2 and the instructions supplied
with the rear-flue kit (code 29450133) on how to re-configure
the flue outlet and how to install the rear-flue terminal.
4.2.1 CONCENTRIC HORIZONTAL FLUE
These instructions relate specifically to the installation of this
appliance with the Vokera 60/100mm ‘X-type’ (click-fit) flue
terminals 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. A reduction must also be
made to the maximum length (see table below) when additional
bends are used.

: Usin
g the template (
A
) provided with the kit, mark and
drill a 125mm hole for the passage of the flue pipe. The hole
should be drilled to ensure any condense fluid that forms, is
allowed to drain back to 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.
NOTE PRE-FIXING JIG
A ‘Pre-fixing Jig’ is available as an accessory (code 20177531),
should it be necessary to pre-fabricate the appliance pipework,
i.e. first-fix, prior to installing the appliance.
4.2.2 FITTING THE TELESCOPIC HORIZONTAL FLUE
KIT
In some instances it may necessary to cut the inner 60mm pipe
of the flue bend at the point indicated
(Fig. 15 - pos.
A
) to allow
for easier insertion to the boiler flue spigot.

4.2.3 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. 14). 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.
NOTE (Fig. 22):
The appliance incorporates a ‘click-fit’ flue
connection. Ensure that both screws ‘C’ on the ‘click-fit’ have
been slackened off. Ensure that the connector is correctly aligned
with the ‘click-fit’ and insert it into the ‘click-fit’ until it clicks into
position (this is when the tabs at points ‘A’ are located in the
groove of the flue bend connector). Both screws (C) should
now be tightened.
NOTE
Fit the internal (white) 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.
