Instructions for the user
4. USING THE HOB
4.1 Lighting the hob burners
Before lighting the hob burners, check that the flame-spreader crowns are
correctly in place with their respective burner caps, making sure that the holes A
in the flame-spreaders are aligned with the igniters and thermocouples.
The burner controlled by each knob is shown next to the knob.
The appliance is equipped with an electrical ignition device.
Simply press the knob and turn it anti-clockwise to the
maximum flame symbol , until the burner lights.
On valved models, once the burner is lit, keep the knob pressed for a few
seconds to give the thermocouple time to heat up. The burner may go out when
the knob is released: in this case, the thermocouple has not heated up
sufficiently.
Wait a few moments and repeat the operation keeping the knob pressed for
longer. This is not necessary on burners that are not equipped with a
thermocouple.
Once the burner is lit, the flame can be adjusted as required.
Always check that the control knobs are in the O (off) position when you finish
using the hob.
If the burners should go out accidentally, after about 20 seconds a safety device
will be tripped, cutting off the gas supply, even if the gas tap is open. Turn off the
control knob and wait at least 1 minute before trying to re-light the burner.

Instructions for the user
4.2 Practical tips for using the burners
For better burner efficiency and to minimise gas consumption, use pans with a
flat, smooth base and a lid that have a suitable size for the burner, thus
preventing the flames reaching the sides of the pan (see paragraph “4.3 Pan
Diameter”). Once the contents come to the boil, turn down the flame far enough
to prevent the liquid from boiling over.
To prevent burns or damage to the hob during cooking, all pans or griddles must
be placed inside the perimeter of the hob.
Take the greatest care when using fats or oils since they may catch fire if
overheated.
