3) ADJUSTING OF THE MINIMUM OF
THE TOP BURNERS
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 small flat screwdriver turn the
screw inside the tap rod to the correct
regulation (fig. 8.8).
Normally for G30/G31, tighten up the
regulation screw.

The burners are conceived in such a
way so as not to require the regula-
tion of the primary air.
