The width of any hob must not be greater than the width of the
extractor installed above it.
Ducting and ventilation
For best performance and lowest noise output, we recommend the
use of 150mm ducting. You can also use 120mm ducting but this will
reduce performance. In general, the less ducting you use (i.e. distance
and bends) the more efficient your extractor will be.
The lengths of ducting with minimal effect on performance are as
follows:
•
4 metres with 1 x 90° bend.
•
3 metres with 2 x 90° bends.
•
2 metres with 3 x 90° bends.
Longer ducting can be used but the performance of the extractor will
likely be reduced.
Please note
: Ducting components and ducting kits are optional
accessories and have to be ordered, they are not automatically
supplied with the hood. Use of ducting less than 150mm in diameter
will affect performance and increase the noise produced by the
extractor.
