Remember that the earth wire must not be cut out by the switch.

As an alternative, the electrical connection can also be protected with a high sensitivity RCD.
ADJUSTING
•Check the adjustment of the appliance. Before making any adjustment to its operation, ensure proper adjustment to the
sticker data plate, on the bottom of the appliance.
•Before any adjustment is attempted, which may be necessary when installing for the first time or when converting gas
type, take the plug out of the mains socket.
•When the adjustment or preadjustment has been made, a technician must do any re-sealing, if any.
•To adjust “reduce rate”, using proper screw driver, from Natural gas to Butane/Propane ones, light burners one by one
and put handle in minimum position; remove the handle and screw clockwise completely the by-pass screw. Put back in
position the handle and check stability flame, turning the handle from “Maximum” to “Minimum” position and vice-versa.
•To adjust “reduce rate”, using proper screw driver, from Butane/Propane gases to Natural one, light burners one by one
and put handle in minimum position; remove the handle and unscrew anclockwise in the way to get proper flame. Put
back in position the handle and check stability flame, turning the handle from “Maximum” to “Minimum” position and
vice-versa.
•“Primary air adjustment” on hob gas burners is unnecessary.
TAPS
The adjustment of the reduced rate position is as follows:
• Light the burner and turn the knob to reduced rate position (small flame).
• Remove the knob which is simply inserted onto tap stem.
• Insert a small screwdriver into the top shaft and turn the throttling screw left or right until flame of the burner is conveniently
regulated to the low position.
• In the case of taps with safety thermocouples, the adjustment screw is on the side of the stem.
• Make sure that when turning quickly from “Maximum” position to “Minimum” one, the burner does not extinguish.
Attention: if the tap, after long use of the hob, present some friction to rotation, do not use it. Call the nearest
Assistance
Centre of ours that will take action to substitute the tap with the proper one.
CONVERSION
CHANGING THE INJECTORS
The burners can be adapted to different types of gas by simply installing the injectors suitable for the gas you want to use. The “kit
injectors” can be fitted with the appliance or available in an authorised Assistance Centre.
To do this, first remove the burner cups and with a socket spanner, unscrew injectors using proper tool and replace them with injectors
corresponding to the new adjustment gas type. Always tightly lock the injector in place, without adding any material on the injectors
threads: It is forbidden!
To help the installer there is a table on page 10 giving nominal heat inputs, injector diameter and operating pressures of the different
gas types. For best comprehension, each injector is marked on its body with proper diameter.
After the injectors have been changed, the technician must adjust the burners as described in the previous paragraphs, seal
any adjustment or preadjustment parts.
Important: after the conversion, substitute the adjustment sticker data plate put on the bottom of the appliance with the new
one, corresponding to the new gas adjustment. The sticker is included in the “kit injectors”.
MAINTENANCE
Prior to any maintenance work or before changing parts, disconnect the appliance from the gas and electricity power
sources.
REPLACING COMPONENTS
•To access the terminal board and the power cable, it is necessary to remove the hob from the cabinet by unscrewing the relative
fixing screws (V) (see fig. 12).
•If the power cable needs changing, call an authorised Assistance Centre as it is necessary the use of special tools. The
technician will have to connect a cable with a suitable cross section (see the table on page 13) keeping the earth wire
longer than the phase wires. In addition, follow the instructions giving in the “ELECTRICAL CONNECTION” paragraph.
•To replace other gas and electrical components, that are positioned inside the hob, it is necessary to remove the hob top
unscrewing the fixing screws of the burners
•Replace the seal each time you change a tap in order to guarantee a perfect tightness between body and rail.
