6.2 Practical advice for using the hob burners
For better use of the burners and lower gas consumption, use
covered vessel that are proportional in size to the burner to prevent
the flame from heating the sides (see paragraph "6.3 Diameter of
the vessels to be used on each burner"). When water reaches the
boiling point, lower the flame so that it doesn't overflow. To avoid
burns or damage to the hob, all vessels or griddle plates must be
placed within the perimeter of the hob. All vessels must 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.
