Adjusting the flame to minimum on the valve
The flame length at minimum position is adjusted with a flat screw located on the valve. For valves
with thermocouple, the screw is located on the side of the valve spindle (Figure 11).
To determine the min. position, ignite the burners one after another and set them at minimum
position. With the help of a small screwdriver, fasten or loosen the by pass screw around 90
degrees. When the flame has a length of at least 4mm, the adjustment is correct. For control, make
sure that the flame does not die out when passing from the maximum position to the minimum
position. Create an artificial wind with your hand toward the flame to see if the flame is stable.

The bypass screw must be loosened for conversion from LPG to NG. For conversion from NG to LPG,
the same screw must be fastened. Make sure that the appliance is unplugged from the electric
mains and the gas supply is open.
Changing the gas inlet:
Regularly check the expiry date of your cooker gas pipe. When the expiry date is reached, it is
necessary to change the hose. These pipes are available on the market and must be consistent with
current standards. After changing the hose, you should check that there is no leakage by referring
to the information in the above paragraph: Connecting gas and checking leakage.
