4.1 DELIVERY
Due to the weight of the appliance it may be necessary for
two people to lift and attach the appliance to its mounting. The
appliance is contained within a heavy-duty cardboard carton.
Lay the carton on the floor with the writing the correct way up.
4.2 CONTENTS
Contained within the carton is:
• the boiler
• the wall bracket
• carton template
• an accessories pack containing appliance service connections
and washers
• the instruction pack containing the installation, servicing & user
instructions, guarantee registration card and a 3-amp fuse.
4.3 UNPACKING
At the top of the carton pull both sides open – do not use a
knife – unfold the rest of the carton from around the appliance,
carefully remove all protective packaging from the appliance and
lay the accessories etc. to one side. Protective gloves should
be used to lift the appliance, the appliance back-frame should
be used for lifting points.
4.4 PREPARATION FOR MOUNTING THE AP-
PLIANCE
The appliance should be mounted on a smooth, vertical, non-
combustible 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 wall-
mounting bracket (see fig. 10) and flue-hole (if applicable).
4.5 FITTING THE FLUE
The top flue outlet permits both horizontal and vertical flue ap -
plications to be considered, alternatively, the Vokèra 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 can be used with either the Vokèra condensing
60/100mm concentric flue system or the optional 80/125mm
concentric flue system.
NOTE
These instructions relate only to the Vokèra condensing
60/100mm concentric flue system. For specific details on the
installation of the 80/125mm concentric flue system please refer
to the instructions supplied. 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 2.9). A reduction must also be made to the maximum length
(see table below) when additional bends are used.
Reduction for additional bends
Bend Reduction in maximum flue length for each bend
45º bend 1.3 metre (60/100) - 1.0 metre (80/125)
90º bend 1.6 metre (60/100) - 1.5 metre (80/125)

529 Wall bracket pack (5) 208mm
Using the template provided ( A ), 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 (see fig. 12-15). 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 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.13 pos. A) to allow
for easier insertion to the boiler flue spigot.
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 con -
centric 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. Using the clamp, gasket, and screws supplied,
secure the flue bend to the appliance flue spigot.
NOTE
Fit the internal (white) trim to the flue assembly prior to con -
necting the flue pipe to the bend.
You must ensure that the entire flue system is properly sup -
ported 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.
