INFO For each air cleaning unit, there must be a return
flow aperture of at least 1,000 cm² in the plinth
area for recirculation. If the gas flame goes out or
there is a high burner flame delay, the return flow
aperture must be enlarged.
 Ensure that the return flow aperture is large enough.

INFO To ensure that the cooktop performs optimally at all
times, there must be sufficient ventilation beneath
the cooktop.
INFO The performance of the cooktop is affected or the
cooktop overheats if the warm air beneath the
cooktop cannot escape.
INFO If the cooktop overheats, the power is reduced
or the cooktop is switched off completely (see
overheating protection).
INFO If cable protection (false floor) is planned beneath
the appliance, this must be fitted so it does not
obstruct ventilation.
 Make sure that the area below the cooktop has a
sufficient air supply.
5.3.4 Recirculation when using the cooktop
extractor in the recirculation mode
For recirculation, the necessary return flow aperture can
be created using a shortened plinth. A slatted plinth with at
least the minimum opening cross-section can also be used.
