[. . . ] THE SOCKET MUST BE ACCESSIBLE AFTER THE APPLIANCE HAS BEEN BUILT IN. NEVER UNPLUG BY PULLING ON THE CABLE. IMMEDIATELY AFTER INSTALLATION CARRY OUT A BRIEF INSPECTION TEST OF THE COOKING HOB, FOLLOWING THE INSTRUCTIONS BELOW. SHOULD THE APPLIANCE NOT FUNCTION, DISCONNECT IT FROM THE SUPPLY AND CALL THE NEAREST TECHNICAL ASSISTANCE CENTRE. NEVER ATTEMPT TO REPAIR THE APPLIANCE. 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. [. . . ] 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, detach the appliance from the electrical socket. The hob has been inspected for G25 (2L 3B/P) at a pressure of 25 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 Removing the hob 1. Remove all the knobs, the grids, the burner caps and the flame-caps; remove the screws and the nuts A that secure the burner supports; remove plates B; lift the hob from its seat; replace the burner nozzles in accordance with the reference gas chart; 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. 4 Regulation of primary air". Setting corresponds to the elongated part of the knob or to the marking on it. (Only where applicable) Double-crown burners, controlled by two knobs, feature two ribs, a long one corresponding to the small inner burner and a short one to the outer burner. Double-crown burners comprise an auxiliary and a rapid burner, controlled by two different knobs which permit to use both burners at the same time or to select one or the other as required. The device is fit with electronic ignition. Simply press and simultaneously turn the knob counter-clockwise on the low point flame symbol, until the burner is ignited. Concerning models with valves, push the knob for approximately 2 seconds in order to keep the flame burning and to activate the safety device. [. . . ] Check frequently and clean with a damp cloth when necessary. 8. 2. 2 The electric element After use, to make sure that the surfaces are clean and long lasting, the electric element must be treated with specific cleaning products which are available on the market. This necessary operation prevents oxidisation (rust formation). 8. 2. 3 The cover Clean the glass or steel cover, where mounted, with warm water. [. . . ]
