The distance between the top of
the cooker/hob and the bottom of
the cooker hood must measure at least:
– 45 cm above electric cookers/hobs
– 65 cm above gas cookers/hobs.
– 65 cm above an open grill.
For other manufacturer's cooking ap-
pliances maintain the safety distance
as recommended in their Installation
and Operating instructions.
If more than one appliance is fitted be-
neath the cooker hood and they have
different minimum safety distances to
the cooker hood, select the higher dis-
tance.
Safety regulations prohibit the fit-
ting of a cooker hood over solid
fuel stoves.
All ducting, pipework and fittings
must be of non-flammable ma-
terial. These can be obtained from the
Spare Parts department or from buil-
ders' merchants.
The appliance must not be con-
nected to a chimney or vent flue
which is in use. Neither should it be
connected to ducting which ventilates
rooms with fireplaces.
If exhaust air is to be extracted into
a chimney or ventilation duct no
longer used for other purposes, take
professional advice.
When using the cooker hood at the
same time as another heating ap-
pliance which depends on the air in the
room, (e.g. gas, oil or coal fired
6
heaters, continuous flow or other water
heaters, gas cooker, gas hob or gas
oven) special care must be taken, as
the action of the cooker hood extracts
air from the room, which these types of
heater need for combustion.
In order to ensure safe operation, and
to prevent the gases given off by the
heating appliances from being drawn
back into the room when the extractor
and the heater are in operation simulta-
neously, an underpressure in the room
of 0.04 mbar (4 pa) is the maximum
permissible.
Ventilation can be maintained by air in-
lets which cannot be blocked, in win-
dows, doors and outside wall vents, or
by other technical measures, such as
ensuring that the extractor can only be
switched on when the heating ap-
pliance is switched off or vice-versa.
N.B.: The overall ventilation condition of
the dwelling must be taken into ac-
count.
If in any doubt, the advice of a compe-
tent builder or, for gas, a "Corgi" instal-
ler must be sought.
If the cooker hood is used in recircula-
tion mode (with the recirculation Micro-
Filter) , there are no restrictions.
