SETTING THE MINIMUM FLAME
The flame on the small output is regulated
by the factory.
When the injectors have been replaced or
there are special mains pressure conditions,
it may be necessary to regulate the minimum
flame again. The operations necessary to set
the minimum flame are as follows:
1. Light the burner.
2. Turn the knob to the minimum position.
3. Take out the knob (and gasket if there
is one).
4. LPG to NG: use a thin blade screwdriver
to turn the bypass screw located above
gas valve shaft as shown on the image
above. Turn gently the bypass screw
clockwise to the end completely then turn
it anti-clockwise 1 turn for the triple ring,
3/4 turn for the rapid, 1/2 turn for the
semi-rapid and 3/8 turn for the auxiliary.
5.
NG to LPG: use a thin blade
screwdriver to turn the bypass screw
located above gas valve shaft as shown
on the image above. Turn gently the by-
pass screw clockwise to the end.
6. Put the knob back on and turn it quickly
from the maximum position to the
minimum position, checking that the
flame does not go out.
7. For burners with safety valve make sure
that the regulation obtained is sufficient to
maintain heating of the thermocouple. If it
is not, increase the minimum.
Before leaving check all connections for
gas leaks with soap and water.
WARNING // Do not use a naked flame for
detecting leaks.
Ignite all burners both individually and
combined to ensure correct operation of
gas valves, burners and ignition.
ABNORMAL OPERATION
If the appliance cannot be adjusted to
perform correctly, it is an abnormal
situation and you should contact the
authorised service provider.

abnormal operation and may require
servicing:
•• Yellow tipping of the burner flame.
•• Sooting up of utensils.
•• Burners not igniting properly.
•• Burners failing to remain alight.
•• Burners being extinguished by oven door.
•• Gas valves which are difficult to turn.
