2. General technical information
On installing the cooker hood, the following points are to be observed in addition to currently-valid safety
instructions and the respective instructions of your country:
1. The cooker hood must always be installed above the centre of the hob.
2. The clearance may not be smaller than that stipulated for instalment.
The minimum clearance between electric hobs and the lower edge of the hood is 650 mm.
Installing the cooker hood above a gas cooker with a minimum clearance of 750 mm is permissible
only if the following nominal heat input levels (HS) are not exceeded:
Gas cookers
Input level of an individual cooking zone max. 3.0 kW
Input level of all of the cooking zones max. 8.3 kW
Oven input level max. 3.9 kW
Gas hobs
Input level of an individual cooking zone max. 3.9 kW
Input level of all of the cooking zones max. 11.3 kW
Glass ceramic gas hob
Details given on nominal heat input levels do not apply for fully-enclosed glass ceramic gas hobs.
Please follow the manufacturer’s instructions carefully.
3. Exhaust air may not be discharged into a smoke or exhaust gas chimney which is in operation; nor
may it be discharged into a shaft used for ventilating rooms where hearths or fireplaces have been
installed. Should exhaust air be discharged into smoke chimneys or exhaust gas chimneys which
are not in operation, prior approval must be granted by the master chimney sweep responsible.
4. In the case of exhaust air operation of the cooker hood and the simultaneous operation of
heating systems requiring a chimney (such as gas, oil or coal heaters, flow heaters or hot water
boilers), a sufficient supply of inlet air, required by the heating system for combustion purposes,
must be ensured. Negative pressure in the location of a fireplace may not exceed 4 Pa
(0.04 mbar). This is achieved if it is possible for more air to flow in. In order to assess this, the
entire ventilation system of the house or apartment must always be taken into consideration.
In the case of the recirculating air mode of the cooker hood, operation can be carried out without
any restrictions.
5. The cooker hood may only be installed above a fireplace for solid fuels where there may be a risk
of fire (e.g. flying sparks) if the fireplace has a fully-enclosed permanent cover.
