CDA EXTRACTORS CIGE9 - Manual (Page 7)

Installation
IMPORTANT:
The extractor is intended to be mounted directly to
the ceiling using fixings appropriate for the ceiling.
Ensure that there is adequate ceiling strength and
supports at the fixing points; if in doubt, consult a
joiner or electrician.
Mounting Your Extractor:
When the extractor is to be installed above an electric hob,
the minimum distance between the hob and extractor must
exceed 600mm (650mm is recommended)
When the extractor is to be mounted above a gas hob, the
minimum distance between the hob and the extractor must
exceed 700mm (750mm is recommended)
If the instructions provided with your hob state that the
required distance between the hob and extractor must be
greater than 700mm, then that distance should be observed;
this is a legal requirement and may lead to your hob being
disconnected from the gas supply and the installation being
reported to RIDDOR (The height should be measured from
the top of the burners.
IN THE ABSENCE OF ANY SUPPLIED INSTRUCTIONS
WITH YOUR GAS HOB, THE MINIMUM DISTANCE
BETWEEN THE HOB AND EXTRACTOR MUST BE AT
LEAST 760mm
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 120mm ducting. You can also use
100mm ducting but this will reduce performance.
