General installation instructions
Dimensioned drawing
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 a hob and the lower edge of the hood is 250 mm.
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
extraction 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 4Pa
(0.04mbar). This is achieved if it is possible for more air to flow in. The entire ventilation system of
a house or apartment must always be taken into consideration when assessing this.
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.
