Mynute

Using the dimensions given in fig. 9 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
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.

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 1.0metre (28e only).
Connect the vertical flue assembly to the boiler
flue spigot using the 60mm & 100mm clips,
gaskets & screws (supplied), ensuringthe 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. 8B).

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. 8B). 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 4.4.2) 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 1

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.

●

The condensate drain pipe must be connected
in accordance with biulding regulations.

MOUNTING THE BOILER
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.
