General advice

Important

Before you start cleaning, you must ensure that the appliance is disconnected from the electrical power supply.

• When the appliance is not being used, it is advisable to keep the gas tap closed.
• The periodical lubrication of the gas taps must be done only by specialized personnel.
• If a tap becomes stiff, do not force; contact your local After Sales Service Centre.
• It is advisable to clean when the appliance is cold and especially when cleaning the enamelled parts.
• Avoid leaving alkaline or acidic substances (lemon juice, vinegar, etc.) on the surfaces.
• Avoid using cleaning products with a chlorine or acidic base. Important The use of suitable protective clothing/gloves is recommended when handling or cleaning of this appliance. 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 rear or the underneath of the appliance as these areas are not designed or intended to be touched and may contain sharp or rough edges, that may cause injury. Enamelled parts All the enamelled parts must be cleaned with a sponge and soapy water or other non-abrasive products. Dry preferably with a microfibre or soft cloth. Acidic substances like lemon juice, tomato sauce, vinegar etc. can damage the enamel if left too long. Stainless steel, aluminium parts, painted and silk-screen printed surfaces Clean using an appropriate product. Always dry thoroughly. Important These parts must be cleaned very carefully to avoid scratching and abrasion. You are advised to use a soft cloth and neutral soap. Caution Do not use abrasive substances or non-neutral detergents as these will irreparably damage the surface. Important The manufacturer declines all liability for possible damage caused by the use of unsuitable products to clean the appliance. Attention! The appliance gets very hot, mainly around the cooking areas. It is very important that children are not left alone in the kitchen when you are cooking. Do not use a steam cleaner because the moisture can get into the appliance thus make it unsafe. Do not use harsh abrasive cleaners or sharp metal scrapers to clean the oven door glass or the glass lid (models with glass lid only) since they can scratch the surface, which may result in shattering of the glass. Gas taps If the gas taps don't work well please contact the service department. Inside of oven The oven should always be cleaned after use when it has cooled down. The cavity should be cleaned using a mild detergent solution and warm water. Suitable proprietary chemical cleaners may be used after first consulting with the manufacturers recommendations and testing a small sample of the oven cavity. Abrasive cleaning agents or scouring pads/cloths should not be used on the cavity surface. Note The manufacturers of this appliance will accept no responsibility for damage caused by chemical or abrasive cleaning. Let the oven cool down and pay special attention no to touch the hot heating elements inside the oven cavity. Burners and pan supports These parts must be cleaned using a sponge and soapy water or other suitable non-abrasive products. Dry with a soft cloth. Warning! Not dishwasher safe. If left on the surface for a length of time, acidic substances such as lemon juice, tomato sauces and passata, vinegar and other similar products will damage the surface and dull its shine. After cleaning, the burners and their flame spreaders must be well dried and correctly 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. Check that the electrode “S” (figs. 7.1, 7.3) next to each burner is always clean to ensure trouble-free sparking. Check that the probe “T” (figs. 7.1, 7.3) next to each burner is always clean to ensure correct operation of the safety valves. Note Continuous use may cause a change in the glaze around the burners and grids, corresponding to the areas exposed to the heat. This is a natural phenomenon and does not prevent the parts from working properly. Note Both the probe and ignition plug must be very carefully cleaned. To avoid damage to the electric ignition do not use it when the burners are not in place. Correct replacement of the auxiliary and semi-rapid and rapid burners It is very important to check that the burner flame distributor “F” and the cap "C" has been correctly positioned (see figs. 7.1 - 7.2) - failure to do so can cause serious problems. Correct position of the double-ring compact burner The burner must be correctly positioned (see fig. 7.5); the burner rib must enter in their logement as shown by the arrow (see fig. 7.3). Then position the cap “A” and the ring "B" (figs. 7.4 - 7.5). The burner correctly positioned must not rotate (fig. 7.4). Fig. 7.1

• Hang up the wire racks “G” on the oven walls (fig. 7.11) . In the left oven only interpose the catalytic panels "A" (fig. 7.12).
• Slide into the guides, the shelf and the tray (fig. 7.2).
• The rack must be fitted so that the safety notch, which stops it sliding out, faces the inside of the oven; the guard rail shall be at the back. dismantle, operate in reverse order. ADVICE FOR USE AND MAINTENANCE OF SELF CLEANING PANELS Left oven only The self cleaning panels are covered with a special microporous enamel which, absorbs and removes oil and fat splashes during normal baking over 200°C. If, after cooking very fatty foods, the panels remain dirty, operate the oven empty on max temperature for about 30 minutes. These panels do not require to be cleaned, however it is advised to periodically remove them from the oven (at least the side panels) and to wash them with tepid soapy water and then wipe off with a soft cloth. DO NOT CLEAN OR WASH THEM WITH ABRASIVE PRODUCTS OR WITH PRODUCTS CONTAINING ACIDS OR ALKALIS. The side panels are reversible and when the microporous enamel degrades, they can be turned to the other side. LEFT OVEN ONLY 10 0 Telescopic sliding shelf supports (fig. 7.4) The telescopic sliding shelf support makes it safer and easier to insert and remove the oven shelf. It stops when it is pulled out to the maximum position. Important When installing the sliding shelf support, make sure that:
• You fit the RH and LH sliding guides on the wire support (fig. 7.4).
• You press the RH and LH sliding guides against the fixing wires (fig. 7.5). You will hear a click as the safety locks clip over the wire.
• You fit the oven shelf above the sliding shelf support (figs. 7.6, 7.3).
• You slide, on the guides inside the oven cavity, the sliding shelf support with the oven shelf fitted above:
• the oven shelf shall run out towards the oven door;
• do not use the top shelf position;
• the short bend on the wire support shall face the inside of the oven;
• the oven shelf must be fitted so that the guard rail faces the inside of the oven. To remove the RH and LH sliding guides from the wire support:
• Find the safety locks. These are the tabs that clip over the fixing wire (arrow 1 in fig. 7.8).
• Pull the safety locks away from the fixing wire to release the sliding guide (arrow 2 in fig. 7.8). Cleaning the sliding shelf supports:
• Wipe the supports with a damp cloth and a mild detergent only.
• Do not wash them in the dishwasher, immerse them in soapy water, or use oven cleaner on them.

The nozzle diameters, expressed in hundredths of a millimetre, are marked on the body of each injector. If the injectors are not supplied they can be obtained from the "Service Centre". Replacement of the injectors of the cooktop burners To replace the injectors proceed as follows:
• Remove pan supports and burners from the cooktop.
• Using a wrench, substitute the nozzle injectors “J” (figs. 9.10a, 9.10b) with those most suitable for the kind of gas for which it is to be used. The burners are conceived in such a way so as not to require the regulation of the primary air. Auxiliary and Semi-rapid burners Double-ring compact burners Fig. 9.10a Fig. 9.10b Minimum burner setting adjustment Check whether the flame spreads to all burner ports when the burner is lit with the gas tap set to the minimum position. If some ports do not light, increase the minimum gas rate setting. Check whether the burner remains lit even when the gas tap is turned quickly from the maximum to the minimum position. If the burner does not remain lit, increase the minimum gas rate setting. The procedure for adjusting the minimum gas rate setting is described below.
• Light the burner.
• Set the gas valve to the "minimum rate" position.
• Remove the knob.
• Using a screwdriver turn the screw "A" until adjustment is correct (fig. 9.11). Normally for ULPG, the regulation screw is tightened up.
