Ducting and ventilation
For best performance and lowest noise output, we recommend the
use of 150mm ducting. You can also use smaller diameter ducting but
this will reduce performance and potentially increase the noise level
of the extractor whilst in use. In general, the less ducting you use (i.e.
distance and bends) the more
efficient your extractor will be.
Figures 8 and 9 on this page
show the two options for ducting
out - through a wall and through
the ceiling.
Note that the centre line of the
outlet hole is 10cm away from
the wall in Fig. 9.
You may wish to fit the chimney
installation bracket and screws
first before preparing the
ducting outlet area.
Before cutting/drilling through
any surfaces, ensure that
adequate measures have been
taken to ensure no electrical
cables or similar lie behind.
