Injectors Replacement of Top Burners
Every cooker is provided with a set of injectors for the various types of gas.
Injectors not supplied can be obtained from the After-Sales Service.
Select the injectors to be replaced according to the table at page 38.
The nozzle diameters, expressed in hundredths of a millimetre, are marked on the body of each injector.
To replace the injectors proceed as follows:
– Remove the pan supports, the burner caps and flame speaders.
– Using a wrench, substitute the nozzle injectors “J” (Figs. 42 - 43) with those most suitable for the kind
of gas for which it is to be used (see “Table for the choice of the injectors”).
The burners are constructed in such a way so as not to require the regulation of the primary air.
Adjusting of the Minimum of the Top Burners
Considering that in the minimum position the flame must have a
length of about 4 mm and must remain lit even with a quick turn
from the maximum position to that of minimum.
The flame adjustment is done in the following way:
– Turn on the burner
– Turn the tap to the MINIMUM position
– Take off the knob
– With a thin screwdriver turn the screw F until adjustment is
correct (fig. 44).
Normally for LPG, tighten up the regulation screw.
