N.B. When the hob is not being used, set the gas knobs to their closed positions and also close the cock valve on the gas bottle or the main gas supply line. Figure 5 LIGHTING THE BURNERS In order to light the burner, you must: 1 – Press in the corresponding knob and turn counter-clockwise to the full flame position marked by the symbol (fig. 6) and hold the knob in until the flame has been lit. In the case of a mains failure light the burner with a match or lighted taper. 2 – Wait about ten seconds after the gas lighting before releasing the knob (starting time for the valve). 3 – Adjust the gas valve to the desired power. Important If the burner flame should go out for some reason, the safety valve will automatically stop the gas flow. To re-light the burner, return the knob to the closed . position, wait for at least 1 minute and then repeat the lighting procedure. If your local gas supply makes it difficult to light the burner with the knob set to maximum, set the knob to minimum and repeat the operation. Figure 6 CHOICE OF BURNER The burner must be choosen according to the diameter of the pans and energy required. Figure 7 PAN DIAMETER BURNER MINIMUM MAXIMUM Auxiliary 12 cm 14 cm Semirapid 16 cm 20 (1) - 24 cm Rapid 24 cm 26 cm Triple-ring 26 cm 28 cm Woks (2) max 36 cm do not use pans with concave or convex bases (1) Front right Semirapid burner of models HVG 65, 4Q4 only. (2) Models with triple-ring and with wok pan adapter (the wok pan adapter is available as an accessory at extra cost): wok pans have to be used only with the special grille fitted (see correct use of triple-ring burner). Saucepans with handles which are excessively heavy, in relationship to the weight of the pan, are safer as they are less likely to tip. Pans which are positioned centrally on burners are more stable than those which are offset. It is far safer to position the pan handles in such a way that they cannot be accidentally knocked. When deep fat frying fill the pan only one third full of oil. DO NOT cover the pan with a lid and DO NOT leave the pan unattended. In the unfortunate event of a fire, leave the pan where it is and turn off all controls. Place a damp cloth or correct fitting lid over the pan to smother the flames. DO NOT use water on the fire. Leave the pan to cool for at least 30 minutes. CORRECT USE OF TRIPLE-RING BURNER . The flat-bottomed pans are to be placed directly onto the pan-support. . To use the WOK you need to place the proper stand (available as an accessory at extra cost) in order to avoid any faulty operation of the triple-ring burner (Figs. 8a -8b). IMPORTANT: The special grille for wok pans (available as an accessory at extra cost) (fig. 8b) MUST BE PLACED ONLY over the pan-rest for the triple-ring burner. Figure 8a Figure 8b WRONG CORRECT Figure 9 Cleaning and Maintenance Cleaning and Maintenance GENERAL TIPS . Before cleaning the hob switch it off and wait for it to cool down. . Clean with a cloth, hot water and soap or liquid detergent. . Do not use products which are abrasive, corrosive or chlorine based. . Do not use steel pads. . Do not leave acid or alkaline substances (vinegar, salt, lemon juice, etc.) on the hob. . Do not use steam jet cleaners because the humidity could infiltrate into the appliance making it dangerous. . WARNING: When correctly installed, your product meets all safety requirements laid down for this type of product category. However special care should be taken around the underneath of the appliance as this area is not designed or intended to be touched and may contain sharp or rough edges, that may cause injury. GLASS SURFACE . Remove spillages and other types of incrustations by using only specific products which do not contain abrasives or chlorine-based acids. . If you use a detergent, please make sure that it is not abrasive or scouring. Abrasive or scouring powders can damage the glass surface of the hob. . All traces of the cleaner must be removed with a damp cloth. . Dust or food particles can be removed with a damp cloth. . Dust, fat and liquids from food that has boiled over must be removed as soon as possible. . If they are allowed to harden they become increasingly difficult to remove. This is especially true in the case of sugar/syrup mixtures which could permanently damage the surface of the hob if left to burn on it. . Avoid using a knife or other sharp utensil as these may damage the glass surface. . Do not use steel wool or an abrasive sponge which could scratch the surface permanently. . Do not put articles on the hob which can melt: i.e plastic, aluminium foil, sugar, sugar syrup mixtures etc. Do not use harsh abrasive cleaners or sharp metal scrapers to clean the glass since they can scratch the surface, which may result in shattering of the glass. ENAMELLED PARTS . All the enamelled parts must be washed only with a sponge with soapy water or other non-abrasive products. . Dry preferably with a soft cloth. . If acid substances such as lemon juice,...
