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.8) 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.9-9/A) 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.
MAINTENANCE
Replacing the power supply cable
If the power supply cable should be replaced,
it is necessary to use a cable with a section of
3x0.75mm 2 type H05V2V2-F or H05RR-F for
models all gas or 3x1.5mm 2 type H05V2V2-F or
H05RR-F for models mixed, complying with the
regulations in force.
The connection to the terminal board must be
effected as shown in fig. 10-10/A:
brown cable L (phase)
blue cable N (neutral)
green-yellow cable (ground)
If the supply cord is damaged, it must be replaced
by the manufacturer, its service agent or similarly
qualified persons in order to avoid a hazard.
