10.8 Pyrolysis: automatic oven cleaning
(on some models only)
Pyrolysis is an automatic high-temperature cleaning procedure which causes
dirt to dissolve. Thanks to this process, it is possible to clean the inside of the
oven with great ease.
During the first automatic cleaning cycle, unpleasant smells may occur due to the normal
evaporation of oily manufacturing substances. This is an absolutely normal phenomenon
which disappears after the first cleaning cycle.
Before starting the automatic cleaning cycle, make sure that the oven does not
contain any foods or large spills from previous cooking operations.
During the pyrolysis cycle, a door locking device makes it impossible to open
the door.
If the oven is installed under a hob, make sure that the burners or electric
hotplates on the hob remain switched off during the automatic cleaning cycle.
