LUBRICATION OF THE GAS TAPS
If a tap becomes stiff, do not force;
contact your local Service Agent.
2 - 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
– 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. 9.5).
Normally for LPG, tighten up the
regulation screw.
