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 APPLIANCE
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. 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.
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 condensing
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 2.8). A
reduction must also be made to the maximum length (see
table below) when additional bends are used.
SECTION 4
INSTALLATION
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.
