Adjustment of minimum level
To adjust the minimum level of the burners,
proceed as follows:
•
Light the burner.
•
Turn the knob on the minimum position.
•
Remove the knob.
•
With a thin screwdriver, adjust the by-
pass screw. Depending on the the
different types of gas taps, it may be
located inside the tap shaft, or on the tap
body (see Fig. 26).
If changing from natural gas G20 to
liquid gas G30/G31
, completely tighten
clockwise the screw, until a small regular
flame is obtained.
If changing from liquid gas G30/G31
to natural gas G20
, loose the screw
about 1/4 of a turn, until a small regular
flame is obtained.
•
Finally check the flame does not go out
when quickly turning the knob from the
maximum position to the minimum
position.
