ADJUSTMENT OF THE OVEN AND
GRILL BURNERS MINIMUM
This needs to be done only for the oven
burner (the grill is a fixed capacity) by
acting on the thermostat in the following
way:
– turn on the burner by setting the ther-
mostat knob on position 10
– remove the knob and unscrew the by-
pass screw (fig. 10.12) about three
times by passing a small flat screw-
driver (Ø 3 mm blade, 100 mm length)
through the panel opening
– re-mount the knob and let the oven
heat up for about 10 minutes, then
bring the knob to position 1 (minimum)
to operate the thermostat by-pass
– after having removed the knob again
and being very careful not to turn the
tap rod, slowly screw the by-pass
screws “G” (fig. 10.12) until you obtain
a flame of 3-4 mm in height.
N.B. For G30/G31 the by-pass screw
must be fixed thoroughly.
