[. . . ] SEPARATE THE VARIOUS WASTE MATERIALS AND TAKE THEM TO THE NEAREST SPECIAL GARBAGE COLLECTION CENTRE. IT IS OBLIGATORY FOR THE ELECTRICAL SYSTEM TO BE GROUNDED ACCORDING TO THE METHODS REQUIRED BY SAFETY RULES. THE PLUG TO BE CONNECTED TO THE POWER CABLE AND THE SOCKET MUST BE THE SAME TYPE AND MUST CONFORM TO CURRENT REGULATIONS. IMMEDIATELY AFTER INSTALLATION CARRY OUT A BRIEF INSPECTION TEST OF THE COOKING HOB, FOLLOWING THE INSTRUCTIONS BELOW. [. . . ] The gas intake fitting is ½" gas external threaded (ISO 2281). Connection with rigid copper pipe: the connection to the gas mains must not provoke stress of any kind on the hob. Connection may be made by using biconical adapter D with insertion of gasket C (supplied). Connection with flexible pipe: use only flexible pipes conforming to standard regulations in force, inserting gasket C (supplied) between fitting A and flexible pipe E. The flexible pipe has to be installed so that pipe length does not exceed 1. 5 meters of maximum extension. Make sure that the pipes do not touch any moving parts or become damaged. 27 Instructions for the installer 4. 1 Connection to LPG Use a pressure regulator and make the connection to the tank according to the provisions of standards regulations in force. Make sure that feed pressure conforms to the levels shown in the table in paragraph "5. 2 Regulation for LPG". 4. 2 Ventilation of rooms The hob may be installed only in rooms with permanent ventilation, as required by standards regulations in force. The room in which the hob is installed must have sufficient air flow to satisfy the requirements of normal gas combustion and of necessary air exchange in the room. The air intakes, protected by screens, must be appropriately sized (regulations in force) and placed so as not to be blocked in any way. The room where the oven is installed should be suitably ventilated to avoid overheating or excess humidity produced by cooking, and in the case of lengthy use a window should be opened or the speed of any ventilators should be increased. 4. 3 Discharge of combustion products Discharge of combustion products must be guaranteed by means of hoods connected to a natural draught flue with certain efficiency, or by means of forced aspiration. An efficient aspiration system requires careful planning by a specialist capable of installing it, respecting the positions and distances prescribed by standards. After installation, the installer must issue a certificate of conformity. 28 Instructions for the installer 5 ADAPTATION TO DIFFERENT TYPES OF GAS Before performing any cleaning or maintenance work, disconnect the appliance from the electrical socket. The hob has been inspected for G20 (2H) natural gas at a pressure of 20 mbar. For functioning with other types of gas the nozzles must be replaced and the primary air adjusted. To replace the nozzles and regulate the burners, you have to remove the top as described in the following paragraph. 5. 1 1. 5. Removing the hob Remove all the knobs, the grids, the burner caps and the flamecaps; Remove the screws and the nuts A that secure the burner supports; Lift the hob from its seat; Replace the burner nozzles in accordance with the relevant gas table; Regulate the primary air as described in paragraph "5. 2 Regulation for LPG". 29 Instructions for the installer 5. 2 Regulation for LPG Loosen screw A and push support B all the way. Use a double head wrench to remove nozzle C and assemble the suitable one, following the instructions indicated in the reference charts, with respect to the type of gas to use. The screwing torque of the nozzle should never exceed 3 Nm. Reposition support B so that nozzle C is covered perfectly. 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. 5 Regulation of primary air". After the regulations have been carried out, restore the seals with sealing wax or equivalent material. [. . . ] Grids, caps, flame cap crowns and burners can be removed for ease of cleaning. Wash them in warm water using a non-abrasive detergent, taking care to remove all tough spots. Before remounting, allow the components to fully dry out. In fact, humidity residues inside the burner holes might impair burner operation. [. . . ]
