USE OF THE OVENS

Warnings and general advice
Before using the oven for the first time, pre-heat it to maximum
temperature (250°C) long enough to burn any manufacturing oily
residues which could give the food a bad taste.
The user has only to press the central key for 1/2 seconds to enable
use of the oven on first use or after a power blackout.
To avoid problems that may be caused by any vapour
in the ovens, open the doors in two phases: keep them
half open (about 5 cm) for 4-5 seconds then open them
completely. If you need to attend to the food the doors
should be left open for the shortest time possible, thus
avoiding lowering of internal temperature to a point that
might jeopardise final cooking results.
During cooking, do not cover the bottom of the oven with aluminium or tin
foil and do not place pans or oven trays on it as this may damage the
enamel coating. If you wish to use greaseproof paper, place it so that it
will not interfere with the hot air circulation inside the oven.
