[. . . ] THIS GUIDELINE IS THE FRAME OF A EUROPEAN-WIDE VALIDITY OF RETURN AND RECYCLING ON WASTE ELECTRICAL AND ELECTRONIC EQUIPMENT. The manufacturer declines all responsibility for damage to persons or things caused by non-observance of the above prescriptions or by interference with any part of the appliance or by the use of non-original spares. 23 Instructions for the installer 2. POSITIONING OF HOB The following operation requires building and/or carpentry work so must be carried out by a competent tradesman. Installation can be carried out on various materials such as masonry, metal, solid wood or plastic laminated wood as long as they are heat resistant (T 90°C). Never use silicone or other insulating products when installing the appliance; use only the rubber gasket provided. [. . . ] This device is classified "type Y" as regards risks against fire and it can be set adjacent to walls that are higher than the work surface, provided that a distance of 145 mm. is respected (as shown in the figure) to prevent damage due to overheating. Make sure there is a minimum of 750 mm between the hot plate flames and any shelf that may be installed directly above them. Carefully position the insulation gasket (supplied) on the external perimeter of the hole made in the top surface (see figures below) and try to make it stick to the entire surface by applying light pressure with your hands. Refer to the coordinates shown in the figure, bearing in mind that sides A should be adjacent to the hole. The distances in the following drawing refer to the hole on the inner side of the gasket. 24 Instructions for the installer In case of installation on a hollow compartment with doors, a separating panel has to be placed under 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. 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. 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. Move the Venturi tube D to regulate the air flow until distance "X" is reached indicated in the chart in paragraph "5. 4 Regulation of primary air" and then secure the tube by means of screw A. 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.

FINAL OPERATIONS Having carried out the above adjustments, reassemble the appliance following, backwards, the instructions in paragraph "5. 1 Removing the hob". 6. 1 Regulation of minimum for natural gas Replace the components on the burner and slide the knobs on the gas tap pins. 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 gas other than the one tested, replace the label located on the guard with the one that corresponds to the new gas. The label is inside the bag that contains the nozzles provided. 32 Instructions for the installer 6. 3 Arrangement of burners on hob BURNERS 1 2 3 4 5-6 7 Auxiliary Semi-rapid Average rapid Large rapid Triple crown Double crown 6. 4 Lubrication of gas taps After a while, the gas tap may become hard to turn or lock.

USING THE HOB Make sure that the flame-baffle crowns, the caps and the grid have been assembled correctly. Adapter B (supplied) is to be used for small vessels. 7. 1 Ignition of the burners with safety device For each knob the corresponding burner is indicated. 8. 1. 1 Regular daily cleaning of the hob In order to clean and preserve the surface, always use specific products only, which do not contain abrasive substances or chlorine-based acid substances.
