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.
Considering that 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 burner by setting the
thermostat knob on position
10
(maximum);
•
remove the knob and unscrew the
by-pass screw “
G
” (fig. 9.12) about
three times by passing a small flat
screwdriver (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. 9.12) until you obtain
a flame of 3-4 mm in height.
Normally for LPG (G30/G31), tighten up
the regulation screw.
