SECTION 4
INSTALLATION
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
●
template
●
an accessories pack containing appliance service con-
nections and washers
●
the instruction pack containing the installation & servic-
ing instructions, user instructions, guarantee registra-
tion 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 appli-
ance, carefully remove all protective packaging from the
appliance and lay the accessories etc. to one side. Protec-
tive gloves should be used to lift the appliance, the appli-
ance back-frame should be used for lifting points.
4.4
PREPARATION FOR MOUNTING THE APPLIANCE
The appliance should be mounted on a smooth, vertical,
non-combustible surface, which must be capable of support-
ing 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. 6) and flue-hole (if
applicable).
4.5
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.
FLUE RESTRICTOR RING (horizontal flue)
To ensure maximum efficiency of the appliance, it may be
necessary to fit one of the supplied flue restrictor rings to the
appliance flue outlet (see tables below).
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 Vokera con-
densing 60/100mm concentric flue system or the optional
80/125mm concentric flue system.
NOTE
These instructions relate
only
to the Vokera 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.

Using the template provided, mark and drill a 115mm 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. 7A).
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 45mm to dimension X to give you
dimension Y (see fig 7A). Measure dimension Y from the
terminal end of the concentric flue pipe and cut off the
excess ensuring any burrs are removed. Pass the concen-
tric 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 clamps, gaskets and screws supplied, secure the
flue bend to the appliance flue spigot.
NOTE
Fit the internal (white) trim to the flue assembly prior to
connecting the flue pipe to the bend.
