4.5.3.2 INSTALLATION OF CONDENSATE DRAIN KIT
(fig. 10B)
The condensate drain kit must be fitted within 1 metre
of the appliance flue outlet. It is recommended that
the condensate drain kit should be fitted in the vertical
plane, however it can be fitted horizontally with care.
●
Fit the first bend to the condensate drain kit or
exhaust connection manifold by firmly pushing
in to position.
●
Using the two holes in the exhaust connection
manifold as a guide, drill a 3 mm hole in each
and secure using the screws provided.
●
Connect the air inlet pipe to the air baffle as above.
●
The twin flue pipes extensions and accessories
can now be installed by pushing together (the
plain end of each extension or bend should be
pushed approximately 50 mm into the female
socket of the previous piece).
The condensate drain trap must be connected
to the drain in accordance with building
Regulations or other rules in force.

The Vokera twin flue system enables greater flue
distances to be achieved (see section 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 1º 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.
●
Extreme care must be taken to ensure that no
debris is allowed to enter the flue system at
any time.
●
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.
