6.2 Practical advice for using the cooking hob burners
For better use of the burners and lower gas consumption, use covered
containers that are proportional in size to the burner to prevent the flame
from licking the sides (see paragraph “6.3 Diameter of containers”).
When water reaches the boiling point, lower the flame so that it doesn’t
overflow. To avoid burns or damage to the hob, all recipients or griddle
plates must be placed within the perimeter of the cooking hob. All
containers have to have a flat and smooth bottom. When using fats or
oils, be extremely careful that they don’t overheat and catch fire.
If the flame accidentally goes out, turn off the control knob and wait at
least 1 minute before trying to re-light the burner.

7. USE OF THE OVENS
7.1 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.
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.
