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. 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.

flame to see if the flames are stable.

minimum position for 5 minutes, then open and
close the oven door for 2-3 times to check the
