Using the dimensions given in fig. 8 as a reference,
mark and cut a 105mm hole in the ceiling and/or roof.
IMPORTANT
You must ensure that the terminal is at least
300mm from any structure or surface (see fig. 8).
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.
Encure that any horizontal sections of the flue system
have a 1
°
fall back to the boiler (17mm per 1000mm).
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.
NOTE
When cutting an extension to the required length,
you must ensure that the excess is cut from the
plain end of the extension.
Remove any burrs, and check that any seals are
located properly.
4.5.3
TWIN FLUE SYSTEM
The Vokera twin flue system enables greater flue
distances to be achieved (see 2.8) 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 forms
in the flue system to 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.
●
As the exhaust outlet pipe can reach very high
temperatures it must be protected to prevent
persons touching the hot surface.
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.
4.5.3.1 INSTALLATION OF TWIN ADAPTOR KIT (see
fig. 9)
●
Discard the restrictor ring (supplied with the twin
adapter kit).
●
Insert the exhaust connection manifold onto the
appliance flue outlet.
●
Place the silicone seal (supplied with twin
adapter kit) over the rim of the exhaust
connection manifold.
●
Remove one of the blanking plate (located to
the left & right of the appliance flue outlet) and
– using the same screws – install the air baffle.
