Miele DA 6708 D Operating And Installation Instructions page 9

Correct installation

Refer to the cooker or hob manufacturer's instructions as to
whether a cooker hood may be operated above the cooker/hob.

Safety regulations prohibit the fitting of a cooker hood over solid
fuel stoves.

Insufficient distance between the cooker or hob and the cooker
hood can result in damage to the hood.
The minimum safety distances between the top of the cooker or hob
and the bottom of the cooker hood given in the „Installation" section
must be maintained, unless the hob manufacturer states that a
greater distance is required.
If more than one cooking appliance is fitted beneath the cooker
hood, and they have different minimum safety distances to the
cooker hood, select the greater distance.

The distances given in „Installation" must be observed when
fitting the cooker hood.
