To restore operation, move the knob to position and repeat the igniting operations described in the next
section.
Using burners with safety valves
o
Turn the knob of the gas tap to the maximum supply position, then press and hold down for about 4-
5 seconds.
Release the knob and adjust the flame by turning the knob until reaching the desired intensity.
o
Warning :
The ignition device cannot be operated for more than 15.
If after this period the burner still has not lit, or if it has gone out for accidental reasons, wait at least
1 minute before repeating the operation.
Burner selection
The symbol printed above each knob on the control panel (drawing in fig.4) indicates the correspondence
between knob and burner. The selection of the most suitable burner depends on the diameter and capacity
of the cookware (see table).
It is important that the pot diameter is suited to the power of the burner, in order to not compromise its high
efficiency.
Adapt ing to different types of gas
If it is necessary to adapt the cooktop to gas different than that for which it is designed, the injectors will have
to be replaced.
The spare injectors, if not provided with the cooktop, are available at the Service Centres.
The injectors to be replaced should be selected according to the injectors table.
The injectors are identified by their diameter, expressed in hundredths of mm and printed on the body of the
injectors themselves.
Replacement of the injectors
Remove the grates and the flame spreader from the cooktop.
Use an open-end spanner to replace the injectors J (fig. 10) with the appropriate injectors for the gas
to be used.
Reassemble the burners.
No primary air regulation is necessary for the burners.
Adjustment of the minimum
After replacing the injectors, light the burner and take off the knob. Move the tap to the minimum position,
insert a screwdriver in the rod and adjust as follows: screw in to decrease the flame, unscrew to increase the
flame. (fig. 10)
For G30/G31 gas, screw the adjustment screw in completely.
In any case, the result should be a small flame which is uniform and regular along the entire crown of the
burner.
Finally, check that the flame does not go out when the tap is turned quickly from maximum to minimum
position. For burners with safety valves, check that the flame slightly licks the thermocouple. Verify the
correct adjustment by leaving the burner on for a few minutes. If it goes out, increase the minimum.
