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 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 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
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.

4.5.1.1 EXTENDING THE FLUE
Connect the bend – supplied with the terminal kit – to the
top of the boiler using clamp (supplied) see fig. 7. The
additional bends & extensions have push-fit connections,
care should be taken to ensure that the correct seal is
made when assembling the flue system. Connect the
required number of flue extensions or bends (up to the
maximum equivalent flue length) to the flue terminal (see
fig. 7 & 8).
The flue system should have a minimum of 1º; maximum
of 3º rise from the boiler to outside, to ensure any condense
fluid that forms, is allowed to drain back to the appliance.
NOTE
When cutting an extension to the required length, you must
ensure that the excess is cut from the plain end of the
extension (see fig. 7 & 8). Remove any burrs, and check
that all seals are located properly.
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 interior and exterior trim can now be
fitted.
4.5.2 CONCENTRIC VERTICAL FLUE
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 vertical flue terminal can be connected directly to the
appliance flue outlet. Alternatively, an extension or bend
can be connected to the appliance flue outlet if desired
(see 4.4.2), however if additional bends are fitted, a
reduction must be made to the maximum flue length (see
table below).
