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
– Models without safety valve device.
With a small flat screwdriver turn the
screw inside the tap rod to the correct
regulation (fig. 9.11).
– Models with safety valve device.
With a thin screwdriver pass by the
hole of microswitch and turn the
screw F until adjustment is correct (fig.
9.12).
Normally for G30/G31, tighten up the
regulation screw.
