4.5 FITTING THE FLUE
The top
fl
ue outlet permits both horizontal and vertical
fl
ue ap-
plications to be considered, alternatively, the Vokèra twin
fl
ue
system can be utilised if longer
fl
ue runs are required.
4.5.1 CONCENTRIC HORIZONTAL FLUE
(For concentric vertical
fl
ue, see 4.5.2).
(For twin
fl
ue applications, see 4.5.3).
The appliance can be used with either the Vokèra condensing
60/100mm concentric
fl
ue system or the optional 80/125mm
concentric
fl
ue system.
NOTE
These instructions relate
only
to the Vokèra condensing
60/100mm concentric
fl
ue system. For speci
fi
c details on the
installation of the 80/125mm concentric
fl
ue system please refer
to the instructions supplied. The appliance
fl
ue outlet elbow can
be rotated through 360º on its vertical axis. In addition the
fl
ue
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 125mm hole for
the passage of the
fl
ue pipe. The hole should be drilled to ensure
any condense
fl
uid that forms, is allowed to drain back to the
appliance (see
fi
g. 12-14). The
fi
xing holes for the wall-mounting
bracket should now be drilled and plugged, an appropriate type
and quantity of
fi
xing 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
fl
ue outlet to the edge of the
fi
nished outside wall (dimension
X). Add 65mm to dimension X to give you Dimension Y (see
fi
g 16). Measure dimension Y from the terminal end of the con-
centric
fl
ue pipe and cut off the excess ensuring any burrs are
removed. Pass the concentric
fl
ue pipe through the previously
drilled hole. Fit the
fl
ue bend to the boiler
fl
ue outlet and insert
the concentric
fl
ue pipe into the
fl
ue bend ensuring the correct
seal is made.
Using the clamp, gasket, and screws supplied,
secure the
fl
ue bend to the appliance
fl
ue spigot.
NOTE
Fit the internal (white) trim to the
fl
ue assembly prior to con-
necting the
fl
ue pipe to the bend.
You must ensure that the entire
fl
ue system is properly sup-
ported and connected. Seal the
fl
ue assembly to the wall using
cement or a suitable alternative that will provide satisfactory
weatherproo
fi
ng. The exterior trim can now be
fi
tted.
