[. . . ] Illustrations for the use of the appliance are grouped together at the end of this manual. This appliance conforms to the following EC directives: - - - - - 90/396/EEC "Gas safety requirements" 73/23/EEC "Low voltage" 89/336/EEC "Electromagnetic compatibility" 93/68/EEC "General Standards" 89/109/EEC "Materials or objects destined to come into contact with foodstuffs" These instructions are valid only for those countries whose ID initials appear on the data plate found on the instructions handbook and on the appliance. The use of a gas cooking appliance produces heat and humidity in the room in which it is installed. Ensure the kitchen is well ventilated: keep natural ventilation openings open, or install a mechanical ventilation device (extractor hood with exhaust duct). [. . . ] Using the burners For models fitted with ignition incorporated in the knobs, turn the gas tap knob to the maximum delivery position, then press and hold down for about 4÷ 5 seconds. Release the knob and adjust the flame by turning the knob to the desired intensity. For models fitted with ignition switch, turn the gas tap knob to the maximum delivery position, then press the ignition switch and the knob, holding down for about 4÷ 5 seconds. Then release the knob and adjust the flame by turning the knob to the desired intensity. 'Warning': The ignition device must not be used for more than 15 seconds. If after this length of time the burner does not light, or if it goes out again accidentally, wait 1 minute before trying to ignite the burner again. To choose the most suitable burner, take into account the diameter of the pan as well as the pan capacity (see table). The diameter of the pan must be proportionate to the burner power in order to ensure high yield. If a different type of gas from the one indicated on the rating plate is used, the injectors must be replaced. If spare injectors are not supplied with the appliance, they are available from the After-sales service. for the choice of replacement injectors , refer to the injectors table. Installation area In the room where the gas appliance is installed, there must be a sufficient natural air supply to allow the gas to burn correctly. The natural flow of air must take place through an opening made on an outside wall of the room and 2 having a working section of at least 100 cm (A). In the case of appliances without safety valves, this 2 opening must have a minimum working section of 200 cm (fig. This opening must be made in such a way that it cannot be obstructed from inside or outside. It should be positioned near floor level, preferably on the side opposite the fume exhaust devices. If it is not possible to make the necessary openings, the air can be supplied from an adjacent, suitably ventilated room, as long as this room is not a bedroom, a dangerous area or a low-pressure area. Removal of combustion fumes Combustion fumes produced by gas appliances must be removed by means of a hood connected directly either to an exhaust duct or to the outside (fig. If a hood cannot be installed, an electric extractor fan must be fitted to the outside wall or the window. This electric extractor fan must have a sufficient capacity to guarantee a change of air of the kitchen of at least 3-5 times its volume. Before installation, make sure the type and pressure of the local gas supply are compatible with the cooktop settings. To do this, check the data on the appliance data plate on the cooktop as well as on this handbook. [. . . ] Stainless steel panstand grids may take on a bluish tinge on parts around the burners as a result of the high temperatures. This effect can be reduced by using commercially available steel wool pads. The burners, comprising two parts, can be removed and cleaned using suitable detergents. After cleaning, dry the burners thoroughly and reposition them carefully in their seats. [. . . ]
