[. . . ] ALWAYS CHECK THAT THE CONTROL KNOBS ARE IN THE POSITION "ZERO" (OFF) WHEN YOU FINISH USING THE HOB. 22 Introduction THE IDENTIFICATION PLATE, WITH TECHNICAL DATA, SERIAL NUMBER AND MARKING IS CLEARLY VISIBLE UNDER THE CASING. THE PLATE ON THE CASING MUST NOT BE REMOVED. BEFORE CONNECTING THE DEVICE, MAKE SURE THAT IT HAS BEEN REGULATED FOR THE TYPE OF GAS THAT WILL FEED IT, CHECKING THE LABEL UNDER THE HOB. DO NOT PUT PANS WITHOUT PERFECTLY SMOOTH AND FLAT BOTTOMS ON THE COOKING HOB GRIDS. DO NOT USE PANS OR GRIDDLE PLATES THAT EXTEND BEYOND THE EXTERNAL PERIMETER OF THE HOB. [. . . ] Keep a minimum distance of 10 mm between the bottom of the unit and the panel surface. The panel has to be easily removable to allow access in the event of technical service. 25 Instructions for the installer 3 ELECTRICAL CONNECTION Make sure that the voltage and capacity of the power line conform to the data shown on the plate located under the casing. Do not remove this plate for any reason. The plug on the end of the supply cable and the wall socket must be the same type and conform to the current electrical system regulations. Check that the power line is adequately grounded. On the power line, install an omnipolar cut-off device with contact cut-off distance greater than or equal to 3 mm, located in an easily accessible position near the unit. Do not use reducers, adapters or shunts. If the power cable is replaced, the wire section on the new cable must not be less than 1. 0 mm 2 (3 x 1. 0 cable), keeping in mind that the end to be connected to the hob must have the ground wire (yellow-green) longer by at least 20 mm. Use only H05V2V2-F cable or similar which has a maximum temperature of 90°C. Any replacement needed should be carried out by a specialised technician who should make the mains connections according to the following diagram. L = brown N = blue = yellow-green The manufacturer will not be liable for any damage to persons or property caused by non-observance of the above instructions or deriving from the tampering of even a single part of the hob. 26 Instructions for the installer 4 GAS CONNECTION Connection to the gas mains may be made with a rigid copper pipe or with a flexible pipe and conforming to the provisions defined by standard regulations in force. To facilitate connection, fitting A on the rear of the appliance may be adjusted laterally. After the regulations have been carried out, restore the seals with sealing wax or equivalent material.

To allow the unit to work with this type of gas, perform the same operations described in paragraph "5. 2 Regulation for LPG", but choose the nozzles and regulate the primary air for natural gas, as shown in the following table and in paragraph "5. 4 Regulation of primary air". After the regulations have been carried out, restore the seals with sealing wax or equivalent material.

Light the burner and set it at minimum position. Remove the knob and turn the regulation screw inside or next to the gas tap pin (depending on the model) until you get a suitable minimum flame. Replace the knob and check burner flame stability: (rapidly turning the knob from maximum to minimum position, the flame should not go out). 6. 2 Regulation of minimum for LPG To regulate the minimum for LPG, completely tighten (clockwise) the screw inside or next to the gas tap pin (depending on the model). The diameters of the by-passes for each burner are given in table "5. 2 Regulation for LPG". After having regulated the device with a gas other than the one tested, replace the label located on the bottom enclosure with the one that corresponds to the new gas. The label is inside the bag that contains the nozzles. 32 Instructions for the installer 6. 3 Arrangement of burners on hob Burners 1. [. . . ] In normal use of the hob, the stainless steel burner caps and panstands tend to be burnished by the high temperature. Clean these parts using very fine abrasive sponges or similar commercial products. Then use a specific paste polish to restore the steel's shine. Your local authorised after-sales technician is able to supply professional products for appliance cleaning and care. [. . . ]
