LOW SETTING VALVE ADJUSTMENT
The LOW setting should produce a stable flame when turning the knob from
HIGH to LOW. The flame should be 5mm or lower and must be stable on all
ports on LOW setting.
To adjust: Operate burner on HIGH for about five minutes to preheat burner
itself. Turn knob back to LOW; remove knob, and insert a
small flat tip screwdriver into the centre of the valve stem.
Adjust the flame size by turning adjustment screw in either
direction, while holding the stem (fig. 17)
Flame must be of sufficient size to be stable on all burner ports.
If flame adjustment is needed, adjust ONLY on the LOW setting.
Never adjust flame size on higher setting.
