Adjustment of the Oven Burner Minimum
This needs to be done only for the oven burner (the grill is a fixed capacity) by acting on the thermostat.
In the minimum position the flame 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 flame 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" (fig. 45) about three times by passing a small flat
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 (fig. 46). 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 fixing tongues. Then let it slide downwards to disengage the top fixing 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" (fig. 45) until you obtain a flame of 3-4 mm in height.
− Turn off the burner and reassemble the knob.
N.B. For G30/G31 (LPG) the by-pass screw must be fixed thoroughly.
