Adapting 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,
not provided with the cooktop, are available
at the Service Centres.
The injectors to be replaced should be selected according to
i
njectors table
s
available
at the Service Centres
.
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

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)
T
he 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 tur
ned quickly from maximum to minimum
position. For
