Adjusting the minimum ame position
The ame length in the minimum position is adjusted with a
at screw located on the valve. For valves with a ame failure
device, the screw is located on the side of the valve spindle.
For valves without a ame failure device, the screw is located
inside the valve spindle. For easier reduced ame 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 the minimum position. With the help of a
small screwdriver fasten or loosen the bypass screw around
90 angular degrees. When the ame 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 articial wind with your hand
toward the ame to see if the ames are stable.
