Using the dimensions given in fig. 14 as a reference,
mark and cut a 105mm hole in the ceiling and/or
roof.
Fit the appropriate flashing plate to the roof and
insert the vertical flue terminal through the flashing
plate from the outside, ensuring that the collar on
the flue terminal fits over the flashing.
The fixing holes for the wall-mounting bracket & jig
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 & jig.
IMPORTANT
The vertical flue terminal is 1.0 metre in length and
cannot be cut; therefore it may be necessary to
adjust the height of the appliance to suit or use a
suitable extension.
Remove or discard the flue restrictor ring from the
appliance flue outlet (see fig. 1), if the total flue
length – including the allowance for any additional
bends – exceeds 1.0 metre.
Connect the vertical flue assembly to the boiler flue
spigot using the 60mm & 100mm clips, gaskets, &
screws (supplied), ensuring the correct seal is
made. The flue support bracket (supplied with the
vertical flue kit) can now be fitted.
If the vertical flue requires extension/s or additional
bend/s, connect the required number of flue
extensions or bends (up to the maximum equivalent
flue length) between the boiler and vertical flue
assembly (see fig. 13A).
NOTE
When cutting an extension to the required length,
you must ensure that the excess is cut from the
plain end of the extension and that the inner (60mm)
pipe is 7.5mm longer than outer (100mm) pipe (see
fig. 13A). Remove any burrs, and check that any
seals are located properly.
You must ensure that the entire flue system is
properly supported and connected.

TWIN FLUE SYSTEM
The Vokera twin flue system enables greater
flue distances to be achieved (see 5.4.2) than
that of the standard concentric flue system. It
can be used for horizontal or vertical
applications, however the twin flue system
must be converted to the dedicated concentric
flue kit for termination. It is essential that the
installation of the twin flue system be carried
out in strict accordance with these instructions.
GUIDANCE NOTES ON TWIN FLUE
INSTALLATION
•
The flue must have a fall back of 1º back to
the appliance to allow any condensate that
may form in the flue system to drain via the
condensate drain. Consideration must also
be given to the fact that there is the possibility
of a small amount of condensate dripping
from the terminal.
•
Ensure that the entire flue system is
adequately supported, use at least one
bracket for each extension.
•
The entire flue system must be adequately
insulated to maintain heat within the flue
system thereby reducing the possibility of
condensate production.
As the exhaust outlet pipe can reach very high
temperatures it must be protected to prevent
persons touching the hot surface.
