[. . . ] Using a gas cooking appliance will produce heat and moisture in the room which it has been installed in. Ensure a continuous air supply, keeping the air vents in good conditions or installing a cooker hood with discharge tube. In case of intensive or long time use of the appliance, make the ventilation more efficient, by opening a window or increasing the electric exhaust fan power. Once you removed all packaging from the appliance, ensure that it is not damaged and the electric cable is in perfect conditions. [. . . ] 1 FO 0204 USING THE HOB CORRECTLY To ensure maximum burner efficiency, it is strongly recommended that you use only pots and pans with a flat bottom fitting the size of the burner used, so that flame will not spread beyond the bottom of the vessel (see the table beside). It is also advisable, as soon as a liquid starts boiling, to turn down the flame so that it will barely keep the liquid simmering. Burner Big (rapid) Medium (semirapid) Small (Auxiliary) minimum diameter 180 mm. 160 mm. 4 THE HOB LID In order to make the appliance match with the kitchen design, a lid can be fitted on the hob. l The lid (not provided) is meant to avoid dust to settle on the hob, when it is closed, and to collect splashes of oil or fat, when it is open. l Always clean the lid from cooking residues before opening it or taking it off. Cleaning and Maintenance Disconnect the appliance from the electrical supply, before carrying out any cleaning or manteinance work. GENERAL CLEANING Wash the enamelled components with warm soapy water. Never use abrasive cleaners Frequently wash the "caps" and the "crowns" with hot soapy water, carefully taking away any built-up of food. If the marks are particularly difficult to remove, use common non-abrasive cleaners or specific products. AUTOMATIC IGNITION The automatic ignition of the gas burners is obtained through a ceramic "candle" and a metal electrode (fig. Keep these components well clean, to avoid difficult lighting, and check that the burner crown holes (lett. PAN SUPPORTS The hobs are provided with enamelled pan supports (thin and light - fig. 2). To keep the pan supports in the right position, they are hooked to a couple of special hinges in the back of the hob. Before the appliance is connected: 1) check that the main fuse and the domestic installation can support the load (see the rating label); 2) check that the power supply is properly earthed in compliance with the current rules; 3) check the socket or the double pole switch used for the electrical connection can be easily reached with the appliance built in the forniture unit. Connect the plug, able to support the load marked on the identification plate, to the cable, following the recommendation given in Fig. If connecting the appliance directly to the electric system, it is necessary that you install a double pole switch between the appliance and the electricity supply, with a minimum gap of 3 mm. between the switch contacts and of a type suitable for the required load in compliance with the current rules. The earth cable (yellow/green) must not be interrupted by the interrupter. The connection cable has to be placed in order that, in each part, it cannot reach a temperature of 90 °C. The brown coloured phase cable (fitted in the terminal block contact marked with "L") must always be connected to the network phase. Neutral Earth (yellow/green) REPLACEMENT OF THE VOLTAGE CABLE The connection of the voltage cable to the appliance's terminal block is of type "Y". This means that its replacement requires the specific equipment of a technician. The cable section must be suitable to the voltage and the working temperature. To open the terminal block and reach the terminals, proceed as follows: l insert the point of a screwdriver into the visible protrunding part of the terminal block; l exert a light pressure and lift (Fig. Adaptation to different types of gas REPLACEMENT OF INJECTORS Remove the pan supports. [. . . ] If changing from natural gas to LPG, completely tighten clockwise the screw, until a small regular flame is obtained. Finally check the flame does not go out when quickly turning the knob from the maximum position to the minimum position. 9 By-pass screw BY-pass diameters Burner Ø By-pass in 1/100 of mm. 26 30 38 This procedure can easily be carried out, anyhow the hob has been positioned or built in the working top.
