Adjusting the reduced flame position
The flame length in the minimum position is adjusted with a flat screw located on the valve. For
easier reduced flame adjustment, it is advised to remove the control panel (and microswitch, if
present) during adjustment.
To determine the minimum position, ignite the burners and leave them on in minimum position.
Remove the with the help of a small screwdriver fasten or loosen the bypass screw around 90
angular degrees. When the flame has a length of at least 4mm, the gas is well distributed. 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 flames are stable.
Changing the gas inlet:
For some countries, the gas inlet type can be different for NG/LPG gases. In such a case, remove the
current connection components and nuts (if any) and connect the new gas supply accordingly. In all
conditions, all components used in gas connections should be approved by local and/or
international authorities. In all gas connections, refer to the "Assembly of gas supply and leakage
check" clause explained before.
