Miele H 250 Operating Instructions Manual page 17

Thoroughly clean the ceramic hob be-
fore first use, then clean regularly after
use when just warm to the touch, or
cold. (see the section on "Cleaning and
care").
On first use the hob may give off a
slight smell as moisture in the insulation
evaporates.
For the first few times of using a smell
will occur.
Heat the hotplates for about 5
minutes at the highest setting.
Do not place a pan on them.
The protective coating which prevents
the build-up of rust will smoke slightly
as it hardens.
