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
– Tum 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. 40).
Normally for LPG, tighten up the regulation screw.
