Adjustment of the taps
1. Set the control knobs to minimum.
2. Remove the control knobs from the taps. It has a flexible
rubber valve reinforcing ring. Press with the tip of the
screwdriver to access the tap's adjusting screw.
Never remove the valve reinforcing ring. The valve
reinforcing rings guarantee the watertightness of the
appliance's interior from liquids and dirt, which might
otherwise prevent its correct operation.
3. Adjust the minimum ring setting by turning the by-pass screw
using a flat head screwdriver.
To adjust the minimum flame for N.G. replace the control
knob onto the spindle, light the gas and turn the control knob
to the small flame position. Screw the adjustment screw anti-
clockwise to estabilish a minimum stable flame position. The
flame should remain alight and not burn back to the injector
when the valve is turned quickly from ‘Full On’ to the
“Minimum flame” position and back a few times. To adjust
the minimum flame position for Propane Gas the screw must
be fully tightened down clockwise.
4. Refit the control knobs.
If the by-pass screw cannot be accessed, disassemble the
glass panel and frame described in: Changing double flame
burner tips.
Never remove the tap spindle. In the event of a malfunction,
change the whole tap.
Important: After finishing, stick the sticker, indicating the new
gas type, close to the specifications plate.
