the gas type available (see the label under the
appliance). Follow the instructions indicated in the
chapter “gas transformations and adjustments” for
the possible adaptation to different gases.
The appliance must be connected to the gas
system by means of stiff metal pipes or flexible
steel pipes having continuous walls, in compliance
with the regulations in force.
Some models are equipped with both cylindrical A
and conical B connectors for gas supply (fig. 6).

The connection must not stress the gas ramp.
Once the installation is over, check the

GAS TRANSFORMATIONS AND ADJUSTMENTS
Replacing the nozzles
If the equipment is adjusted for a type of gas that
is different from the one available, it is necessary
to replace the burner nozzles.
The choice of the nozzles to replace must be
made according to the table of the “technical
characteristics” as enclosed.
Act as follows:
-Remove the racks and burners.
-By means of a straight spanner L, unscrew
the nozzle U (fig.7) and substitute it with the
corresponding one.
-Tighten the nozzle strongly.
Adjusting the burners
The lowest flame point must always be properly
adjusted and the flame must remain on even if
there is an abrupt shift from the maximum to the
minimum position.
If this is not so, it is necessary to adjust the lowest
flame point as follows:
-start the burner up
-turn the tap up to the minimum position (small
flame)
-remove the knob from the tap rod
-introduce a flat-tip screwdriver in the hole F of
the tap (fig.8) and turn the by-pass screw up to a
proper adjustment of the lowest flame point.
As regards G30 gas burners, the by-pass screw
must be tightened completely.
