Mounting your Extractor
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.
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 installed above a gas hob, the minimum
distance between the hob and extractor must exceed 700mm (750mm is
recommended).
If the instructions provided with your gas hob state that the required
distance between the hob and extractor must be greater than 700mm,
then that is the distance that 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 INSTRUCTIONS SUPPLIED WITH THE
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. Fig. 5
Ducting and Ventilation
We recommend the use of ducting with a diameter of 150mm. Ducting
with diameters of 100mm or 120mm may be used, but performance will be
reduced.
