REGULATING OF THE OVEN
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 posi-
tion the flame must have a length of
about 4 mm and must remain lit even
with a brusque passage from the maxi-
mum position to that of minimum.
The flame adjustment is done in the fol-
lowing way:
– Light the oven taking the knob to max.
position (
).
– remove the knob and by a thin screw-
driver (3 mm section - 100 mm long)
unscrew of about a half turn the screw
by-pass
G
, passing through the front
panel hole (fig. 9.12)
– fit the knob and let the oven heat for 10
minutes, then take the knob to position
1
allowing the thermostat to work under
by-pass.
– after further removal of the knob, stop
slowly the screw by-pass
G
(being
careful not to turn the knob rod) until
the flame reaches 3-4 mm high.
N.B.
For LPG the by-pass screw must
be fixed thoroughly.
LUBRICATION OF THE GAS TAPS
If the gas tap becomes stiff, it is neces-
sary to dismount it accurately clean it
with gasoline and spread a bit of special
grease resistant to high temperatures
on it.
The operations must be executed by a
suitably qualified and registered techni-
cian.
IMPORTANT
All intervention regarding installation
maintenance and conversion of the
appliance must be fulfilled with origi-
nal factory parts.
The manufacturer declines any liabili-
ty resulting from the non-compliance
of this obligation.
