5. FINAL OPERATIONS
Having carried out the above adjustments, reassemble the appliance
following, backwards, the instructions in paragraph “3.2 Burner and
nozzle characteristics table”.
After adjustment to a different kind of gas from the one for which the
cooker has been tested, replace the plate inside the heating
compartment with one corresponding to the new kind of gas. This plate
can be obtained from your nearest Authorised Assistance Centre.
5.1 Adjustment of minimum for natural gas
Light the burner and take it to the minimum.
Remove the gas tap knob and turn the
adjustment screw inside or at the side of the tap
shaft (depending on the model) until there is a
regular minimum flame. Replace the knob and
check burner flame stability: (rapidly turning the
knob from maximum to minimum position, the
flame should not go out). Repeat the operation on
all the gas taps.
5.2 Regulation of minimum for LPG
To regulate the minimum for LPG, completely tighten (clockwise) the
screw inside or next to the gas tap pin (depending on the model).
The diameters of the by-passes for each burner are given in table “3.2

6. USE OF THE COOKING HOB
6.1 Lighting the burners
Before lighting the hob burners check that the flame caps are in th
e
correct position and that their burner caps are in place, making sure tha
t
the holes Ain the flame caps correspond to the spark plugs an
d
thermocouples.
The optional grid Bis for use with “woks” (Chinese pans).
To prevent damage to the worktop, the hob is equipped with a raise
d
grid C: installs over pans larger than the diameter shown in the table i
n
paragraph " 6.3 Diameter of receptacles". Note that pans larger than 3
0
cm diameter must be used only on the central burner.
Each knob corresponds to the burner indicated. The
appliance is equipped with an electric lighting device.
To light the burners, press and turn the knob
anticlockwise to the large flame symbol . Keep the
knob pressed for about 2 seconds to let the
thermocouple heat up.
If the burner turns off when the knob is released, it means that the
thermocouple isn’t hot enough. Repeat ignition and keep the knob
pressed longer.
Once the burner has been ignited, the flame can be regulated as
required.
Always check that the control knobs are in the position (off) when you
finish using the hob.
If the burners turn off accidentally, a safety device will trip after about 20
seconds to cut off gas flow (even with the gas tap open).

Instructions for the user
6.2 Practical advice for using the 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.
When using fats or oils, be extremely careful that they don’t overheat
and catch fire.
