Adjusting the reduced flame position
The flame length in the minimum position is adjusted with a flat screw located
on the valve. For valves with flame failure device, the screw is located on the
side of the valve spindle(Figure 14). 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.
