How to use the electronic clock The electronic programmer is a device with the following functions: – 24 hours clock with illuminated display – Timing of oven cooking with automatic switch-off (max. 99 minutes). Electronic clock Upon immediate connection of the oven or after a mains failure, three zeros will flash on the programmer panel. To set the clock it is necessary to push the button and then, within 7 seconds, the or button until you have set the correct time.
How to use the hob burners Hob burners Each hob burner is controlled by a separate gas tap operated by a control knob (fig. 5) which has 3 positions marked on the control panel, these are: – Symbol ● : tap closed (burner off) – Symbol : High (maximum) – Symbol : Low (minimum) Push in and turn the knob anti-clockwise to the selected position. Low High Fig. 5 To turn the burner off, fully rotate the knob clockwise to the off position: ●.
Choice of burner The burner must be choosen according to the diameter of the pans and energy required. Burners Pan diameter Auxiliary Semi-rapid Rapid Double-ring 16 cm 16 ÷ 22 cm 20 ÷ 24 cm up to 30 cm Fig. 6 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.
How to use the Multifunction oven OPERATING PRINCIPLES Heating and cooking in the MULTI-FUNCTION oven are obtained in the following ways: a. by normal convection The heat is produced by the upper and lower heating elements. b. by forced convection A fan sucks in the air contained in the oven muffle, which sends it through the circular heating element and then sends it back through the muffle.
OVEN LIGHT By setting the knob to this position, only the oven light comes on (15 W). It remains on in all the cooking modes. TRADITIONAL CONVECTION COOKING The upper and lower heating elements come on. The heat is dispersed by natural convection and the temperature must be set to between 50° and 225°C via the thermostat knob. The oven must be preheated before cooking. Recommended for: Food that requires the same degree of cooking both inside and out, for example roasts, spare pork ribs, meringues etc.
HOT AIR COOKING The circular element and fan come on. The heat is dispersed by forced convection and the temperature can be regulated to between 50° and 225°C via the thermostat knob. The oven does not require preheating. Recommended for: Food which has to be well-cooked outside and soft or rosy inside, for example lasagne, lamb, roast beef, whole fish etc. VENTILATED GRILL COOKING The infrared grill element and the fan come on.
COOKING ADVICE STERILIZATION Sterilization of foods to be conserved, in full and hermetically sealed jars, is done in the following way: a. Set the switch to position . b. Set the thermostat knob to position 185 °C and preheat the oven. c. Fill the dripping pan with hot water. d. Set the jars onto the dripping pan making sure they do not touch each other and the door and set the thermostat knob to position 135 °C.
GRILLING AND “AU GRATIN” Grilling may be done without the roasting jack on position of the switch, because the hot air completely envelops the food that is to be cooked. Set the thermostat to position 175 °C and after having preheated the oven, simply place the food on the rack. Close the door and let the oven operate with the thermostat on position 175 °C, until grilling is done. Adding a few dabs of butter before the end of the cooking time gives the golden “au gratin” effect.
Rotisserie (Fig. 10) This is used for spit roasting under the grill and comprises: – an electric motor fitted to the rear of the oven – a stainless steel skewer provided with slide-out heatless handgrip and two sets of adjustable forks – a skewer support to be fitted in the middle runner. The rotisserie motor is operated by the oven switch (Fig. 9). Fig. 9 Use of the rotisserie – Insert the tray into the lowest rack holders of the oven and insert the rod support into the intermediate rack holders.
