Adjustment of the Oven Burner Minimum
This needs to be done only for the oven burner (the grill is a xed capacity) by acting on the thermostat.
In the minimum position the ame must have a length of about 4 mm and must remain lit even with a
brusque passage from the maximum position to that of minimum.
The ame adjustment is done in the following way:
− Turn on the oven burner by setting the thermostat knob on maximum position “240”.
− Remove the knob and unscrew the by-pass screw “G” (g. 43) about three times by passing a small
at screwdriver (Ø 3 mm blade, 100 mm length) through the control panel opening.
 Note: for the models with glass control panel, for easy access to the by-pass screw, it is suggested
to remove the control panel itself (g. 44). To do that unscrew the two screws on the bottom side
of the control panel and then move, toward the outside, the bottom edge of the glass until the
complete extraction of the bottom xing tongues. Then let it slide downwards to disengage the
top xing tongues.
− Re-mount the knob and let the oven heat up for about 15 minutes, then bring the knob to the
minimum position “125” to operate the thermostat by-pass.
− After having removed the knob again and being very careful not to turn the thermostat rod, slowly
screw the by-pass screws “G” (g. 43) until you obtain a ame of 3-4 mm in height.
− Turn o the burner and reassemble the knob.
N.B. For G30/G31 (LPG) the by-pass screw must be xed thoroughly.
