CONNECTION USING RUBBER HOSES COMPLYING WITH THE CURRENT REGULATIONS IS ONLY PERMITTED IF THE HOSE CAN BE INSPECTED ALONG ITS ENTIRE LENGTH. THE TIGHTENING TORQUE BETWEEN CONNECTIONS THAT INCORPORATE THE GASKET MUST NOT EXCEED 10NM 3. 4. 2 Connection to natural and town gas Make the connection to the gas mains using a rubber hose whose specifications comply with the current regulations (verify that the reference standard is stamped on the hose). Screw the hose connector A to the gas connector B of the appliance, placing the seal C between them. Push the rubber hose D onto the hose connector A and secure it with the clamp E that is compliant with the current standard. 3. 4. 3 Connection to liquid gas Use a standards-compliant pressure regulator and carry out the connection to the gas cylinder in accordance with the regulations in force. Make sure that the supply pressure complies with the values indicated in the paragraph "3. 2/3. 3 Burner and nozzle characteristics table". Screw the small hose connector F onto the large hose connector A; connect the block that this makes to the gas connector B (or use the hose connector G which must be connected directly to the gas connector B) and place the seal C in between them. Push the end of the rubber hose D on to the hose connector A+F (or G) and to the outlet connection of the pressure reducer on the gas cylinder. Secure the end of the hose D to the hose connector A+F (or G) with the standards-compliant clamp I. The hose connector G illustrated is not supplied with the appliance. Only use standards-compliant hose connectors. 78 Instructions for the installer 3. 4. 4 Connection with flexible steel hose (for all types of gas) This type of connection can be made on both built-in and free-standing appliances. Only use standards-compliant steel hoses whose length is not greater than 2 metres. · Turn the adjustment sleeve "B" to the position that corresponds to the type of gas to be used according to the table below. · Tighten the adjustment screw and restore the seals. · When the operation is completed, reassemble the burner correctly. X= NATURAL GAS 5 mm G 30/31 (LPG) 10 mm G 110 ­ TOWN GAS 3 mm 5. FINAL OPERATIONS After replacing the nozzles, reposition the flame-spreader crowns, the burner caps and the pan stands. Following adjustment to a gas other than the preset one, replace the gas adjustment label fixed to the appliance with the one corresponding to the new gas. The label is inserted inside the pack together with the nozzles. 5. 1 Regulation of the hob burners minimum for natural gas Light the burner and turn it to the minimum position . Extract the gas tap knob and turn the adjustment screw at the side of the tap rod until the correct minimum flame is achieved. Refit the knob and verify that the burner flame is stable (turning the knob rapidly from the maximum to the minimum position the flame must not go out). Repeat the operation on all the gas taps. For models with valves, keep the knob at minimum level for a few seconds to keep the flame lit and to activate the safety device. 5. 2 Regulation of the hob burners minimum for liquid gas In order to adjust the minimum with liquid gas, the screw at the side of the tap rod must be tightened clockwise all the way. The bypass diameters for each individual burner are shown in paragraph "4. 2 Burner and nozzle characteristics table (60/70 cm. [. . . ] Rinse thoroughly and dry with a soft cloth or deerskin. Do not allow residues of sugary foods (such as jam) to set inside the oven. If left to set for too long, they might damage the enamel lining of the oven. 10. 2 Cleaning the parts of the cooking hob 10. 2. 1 Pan stands Remove the pan stands and clean them with warm water and non-abrasive detergent, making sure to remove any encrustation. Continuous contact between the pan stands and the flame can cause modifications to the enamel over time in those parts exposed to heat. [. . . ]
