Use of the Hob GAS BURNERS Gas flow to the burners is adjusted by turning the knob illustrated in figs. 3a - 3b which control the valves.
LIGHTING THE BURNERS Models without safety cut-off valves In order to light the burner, you must: Models without electric ignition: 1 – To light one of the gas burners, hold a flame (e.g. a match) close to the top part of the burner, push in and turn the relative knob (fig. 3b) in an anticlockwise direction (fig. 4), pointing the knob indicator towards the large flame symbol (i.e. max. gas flow). 2 – Adjust the burner according to the power required.
LIGHTING THE BURNERS Models fitted with safety cut-off valves In order to light the burner, you must: Models without electric ignition: 1 – To light one of the gas burners, hold a flame (e.g. a match) close to the top part of the burner, push in and turn the relative knob (fig. 3a) in an anticlockwise direction (fig. 4), pointing the knob indicator towards the large flame symbol (i.e. max. gas flow). 2 – Wait about ten seconds after the gas lighting before releasing the knob (starting time for the valve).
CHOICE OF BURNER The symbols printed on the panel by the side of the knob indicate which burner you are controlling. Choose a suitable burner depending on the cookware diameter and capacity. The pan diameter should be suitable for the burner power to make the most of the burner's high efficiency and not waste fuel. A small pan does not boil more quickly on a large burner (fig. 5). Attention: During use the hob becomes very hot under the cooking zones. Keep children away.
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 (supplied with some models only) in order to avoid any faulty operation of the triple-ring burner (Fig. 6a). IMPORTANT: The special grille for wok pans (supplied with some models only) (fig. 6b) MUST BE PLACED ONLY over the pan-rest for the triple-ring burner.
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.
BURNERS AND GRIDS ✓ These parts can be removed and cleaned with appropriate products. ✓ After cleaning, the burners and their flame spreaders must be well dried and correct- ly replaced. ✓ It is very important to check that the burner flame spreader and the cap have been correctly positioned. Failure to do so can cause serious problems. ✓ In appliances with electric ignition, check that the electrode “S” (fig. 7) is always clean to ensure trouble-free sparking.
CORRECT POSITIONING OF THE BURNERS ✓ It is very important to check that the burner flame spreader “F” and the cap “C” have been correctly positioned (see figs. 7 and 8). Failure to do so can cause serious problems.
CORRECT POSITION OF TRIPLE RING BURNER The triple ring burner must be correctly positioned (see fig. 9); the burner ribs must be fitted in their housing as shown by the arrow. The burner correctly positioned must not rotate (fig. 10). Then position the cap A and the ring B (figs. 10 - 11).
