8.2 Practical advice for using the 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 "8.3 Diameter of
containers"). When water reaches the boiling point, lower the flame so
that it doesn't overflow. To avoi d burns or damage to the hob, all
recipients or griddle plates must be placed within the perimeter of the
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.
