User manual SMEG PX1402

[. . . ] INSTRUCTIONS FOR THE USER: these provide recommendations for use, a description of the controls and the correct procedures for cleaning and maintaining the appliance. 19 Precautions for Safety and Use 1. 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. [. . . ] The appliance is tested with G20 (2H) natural gas at the pressure of 20 mbar. For use with other types of gas, see section "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. 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. 24 Instructions for the Installer 5. Adapting to different types of gas The operations described below must be carried out with the appliance not connected to the gas supply. The appliance 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 skin has to be removed. Proceed as described below. 5. 1 Removing the hob skin Remove all the burner components in the numerical order shown below: • • Pull off all the knobs. Lift all the burner components off the hob. 1 • Remove the hob skin fixing screws. 2 • After removing all the components described above, lift off the hob skin. Release all snap connections simultaneously (the hob is connected to the casing underneath in 5 points). Light the burner and turn it to the minimum Remove the knob again and adjust the regulator screw inside or beside the tap rod (depending on the model) until an even minimum flame is obtained. Put the knob back in place and check the stability of the burner flame (the flame must not go out when the knob is turned quickly from the maximum to the minimum setting). 5. 7 Adjusting the minimum for bottled gas To adjust the minimum level when using bottled gas, the adjuster screw inside or beside the tap rod must be turned fully clockwise (depending on the models). [. . . ] 8. 2. 1 The knobs The knobs must be cleaned with a soft cloth dipped in warm water and dried thoroughly. They can easily be lifted off. 8. 2. 2 The pan stands Remove the pan stands and wash them in warm water with a non-abrasive detergent, taking care to remove all deposits. Replace them on the hob following the instructions provided in point “7. 1 Fitting the Pan Stands”. 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.
