4.2.4 Turning on the gas oven

• To light the gas oven pilot flame, press and turn the knob anti-clockwise to the po-

sition shown as item 2 in Fig. 4;

• hold down the knob and at the same time push the ignition button (see item 8 in

Fig. 2 further above);

repeat the operation;

• oven temperature can be controlled within a range between positions shown as

item 3 and item 4 in Fig. 4 (80-300°C/176-572°F and all values in between);

• to turn off the main burner, turn the knob clockwise to the position shown as item

2 in Fig. 4;

as item 1 in Fig. 4.

An unpleasant smell the very first time it is operated can be considered as completely nor-

mal. In fact, this is due to the overheating of insulating materials and residues of oil used

during the metal working process. The first time you turn the oven on, don’t place any

food in the cooking chamber and set the temperature to 300°C (572°F) until the smell dis-

appears.
