Hob burners � Remove the pan support; � Remove the caps and the burner crowns; � Using a No 7 socket spanner unscrew the nozzles and replace them with those required for the type of gas in use (see table no. 1). � Reassemble the parts following the same procedure in reverse. These burners do not need any primary air regulation. Adjustment of minimum level for the hob burners The burner is correctly adjusted when the flame is stable silent and goes out without any noise. When changing the type of gas check that the minimum level is correct. The air admission is correct when the flame is about 4 mm in length. The top burners do not need adjustment of primary air. Check that, turning the knob quickly from the maximum position to the minimum one, the flame does not go out. Hob burners To adjust the minimum level: � Light the burner � Turn the knob to the position of the minimum flame; � Remove the knob; � Unscrew or screw the by-pass screw (on the left above of tap shaft) until a regular small flame is reached. � For LPG screw completely the by-pass screw. � Reassemble the parts following the same procedure in reverse. Check that, when turning the knob quickly from the maximum position to the minimum one, the flame does not go out.
