[. . . ] Instructions for safe and proper use THIS MANUAL IS AN INTEGRAL PART OF THE APPLIANCE AND THEREFORE MUST BE KEPT IN ITS ENTIRETY AND IN AN ACCESSIBLE PLACE FOR THE WHOLE WORKING LIFE OF THE COOKING HOB. WE ADVISE READING THIS MANUAL AND ALL THE INSTRUCTIONS THEREIN BEFORE USING THE COOKING HOB. ALSO KEEP THE SERIES OF NOZZLES SUPPLIED. INSTALLATION MUST BE CARRIED OUT BY QUALIFIED PERSONNEL IN ACCORDANCE WITH THE REGULATIONS IN FORCE. [. . . ] The gas intake fitting is ½" gas external threaded (ISO 228-1). Connection with rigid copper pipe (P64/P705): 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 copper pipe and 90° union (P106): the connection to the gas mains must not provoke stress of any kind on the hob. The connection must be made using a 90° F union, fitting the seal C provided in all cases. Screw the union F onto the gas train H of the hob using 2 spanners in opposite directions. Connection with flexible pipe (All models): 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. 23 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 Section "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. 24 Instructions for the installer 5. Adapting to different types of gas Before performing any cleaning or maintenance work, detach the hob 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 Removing the hob Remove all of the burner components by following the numerical sequence shown in the figure: · remove all of the knobs (1) by pulling them upward; · remove the grids (2), lifting up one of the two horizontal spokes; · remove the burner caps (3) and flame caps (4); · with wrench A (supplied), open the bayonet clamps on the burner rings by levering on guides B; · after having removed all of the above-described components, raise the surface to access the burners and gas taps. 25 Instructions for the installer 5. 2 Regulation for LPG Loosen screw C and push air regulator D to the bottom. With a 7 mm wrench, remove nozzle E and replace it with the proper one (follow the instructions on the reference tables for the type of gas to be used). The torque wrench setting of the nozzle must not exceed 3 Nm. C: The flame is blue, clear and stable and neither comes away from or wraps round the burner; the air is set correctly. 5. 5 Reassembling the hob Follow the instructions given in paragraph "5. 1 Removing the hob ", but in the reverse order. When replacing the burner rings, remember that they have to be tightened completely by means of the wrench supplied, otherwise the flame interruption zones on the flame caps will not be aligned with the grid spokes. When positioning the grids, make sure that the pins are aligned with their seats in the surface, then press them in with the palm of your hand until they lock in place. 5. 6 Regulation of minimum for natural gas Replace the components on the burner and slide the knobs on the gas tap pins. 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. [. . . ] Reassemble the burner caps on their flame caps. When replacing the grids, make sure that pins C are aligned with their seats on the hob, then press them in with the palm of your hand until they lock in place.
