[. . . ] Precautions for safety and use THIS MANUAL IS AN INTEGRAL PART OF THE APPLIANCE. TAKE GOOD CARE OF IT AND KEEP IT TO HAND THROUGHOUT THE HOB'S LIFE CYCLE. USERS ARE ADVISED TO READ THIS MANUAL AND ALL THE INSTRUCTIONS IT CONTAINS BEFORE USING THE HOB. ALSO KEEP THE SET OF NOZZLES PROVIDED IN A SAFE PLACE. [. . . ] Gas connection If the appliance is installed above an over, the gas hose must be passed around the back of the oven to prevent overheating. The connection to the gas mains may be made using a copper pipe or a continuous-wall steel hose in accordance with the relevant regulations. To simplify connection, the horizontal position of the fitting A on the back of the appliance is adjustable. Undo the hexagonal nut B, turn the fitting A into the required position and re-tighten the hexagonal nut B (it has a rubber gasket to ensure it provides an effective seal). When installation is complete, check for any leaks with a soapy solution, never with a naked light. The hob is tested with G20 (2H) natural gas at the pressure of 20 mbar. For use with other types of gas, see point "5. ADAPTING TO DIFFERENT TYPES OF GAS". The gas intake connection has an external ½" gas thread (ISO 228-1). Connection with copper pipe: The connection to the gas supply mains must be made so that no stresses or strains of any kind are applied to the appliance. The connection can be made using the adapter unit D with two conical elements, always fitting the gasket C supplied. Connection with steel hose: use only continuous-wall stainless steel hoses compliant with the relevant regulations, and always fit the gasket C supplied between the fitting A and the hose E. When connecting with a hose, ensure that the total length of the pipeline is not more than 2 metres; also ensure that the hoses do not touch moving parts and are not crushed. 24 Instructions for the Installer 4. 1 Bottled gas connection Use a pressure regulator and make the connection to the gas cylinder in accordance with the relevant regulations. Make sure that the gas supply pressure is as stated in the table in point "5. 2 Adjusting for bottled gas". 4. 2 Room ventilation The appliance may only be installed in a permanently ventilated room as specified by the relevant regulations. The air flow into the room where the appliance is installed must be sufficient for proper gas combustion and room ventilation. The air intakes, protected by gratings, must be of suitable size (see relevant regulations) and located so that they cannot be even partially obstructed. The kitchen must be kept properly ventilated to disperse the heat and humidity produced by cooking processes: in particular, a window should be opened or the speed of any fans increased after prolonged use. 4. 3 Combustion gas discharge Combustion gases must be discharged by means of hoods connected to a flue with reliable natural draught, or a fan extraction system. An effective extraction system requires careful design by an authorised specialist, and must comply with the regulation distances and positions. After installation, the engineer must issue a certificate of compliance. 25 Instructions for the Installer 5. Adapting to different types of gas Before carrying out the operations described below, disconnect the appliance from the electricity supply. The hob is tested with G20 (2H) natural gas at the pressure of 20 mbar. If it is to be used with other types of gas, the burner nozzles have to be changed and the primary air flow adjusted. To replace the nozzles and adjust the burners, the hob plate has to be removed as described below. 5. 1 Removing the hob skin Remove all the burner components in the numerical order shown below: · Remove the pan stands (Fig. 1) by lifting them at the back (1) and extracting them (2). (On 70 cm hobs remove the central pan stand first; on 60 cm hobs the righthand pan stand must be removed first); · remove all the knobs (3, Fig. 2) by pulling them outward; · lift all the burner components off the hob (4-5, Fig. [. . . ] Never clean the knobs or front panel with aggressive products containing alcohol or steel or glass cleaners, since they might cause permanent damage. 8. 2. 2 Pan stands and burners Remove the pan stands and wash them in warm water with a non-abrasive detergent, taking care to remove all deposits. These components must never be washed in a dishwasher. 8. 2. 3 The flame diffuser rings The burner caps and flame diffuser rings can be removed for easier cleaning; wash them in hot water and non-abrasive detergent, taking care to remove all deposits, and wait for them to dry completely. The burner pins A must be fitted into the recesses B in the flame diffuser ring. [. . . ]
