USING GAS BURNERS
■Check that the electricity is switched on to allow spark ignition.
■Make sure that all controls are turned to “ 0” (burner off).
■ The gas ow to the burner is controlled by a tap.
■ You control the ow by turning the knob indicator to line up with the following symbols:
– Symbol 0: tap closed (burner off)
– Symbol : High (maximum)
– Symbol : Low (minimum)
■You can control the temperature by the knob to “High” (maximum) from “Low” “Minimum”.
■Other intermediate operating adjustments can be achieved by positioning the indicator
between the maximum and minimum aperture positions and never between the
maximum aperture and the “ 0” (off) position.
■To switch off, turn the knob clockwise until you hear the safety click.
■Note that, if you are using a burner at the minimum setting, you turn the knob clockwise
past the maximum setting before reaching the off position.
■ Whenever lighting any of the burners produces an abnormal ame, switch that burner
off and relight using the minimum setting.
■ If after relighting the burner the ame is still abnormal, turn the burner off and contact
our Customer Service Centre to obtain the nearest authorized Delonghi Service Agent.
■In the case of a mains failure light the burner with a match or lighted taper.
■Note: When the cooker top is not being used, check the gas knobs are in their
closed position and also close the cock valve on the gas bottle or the main gas
supply line.
Figure 8

19
In order to light the burner, you must:
1. Turn the knob (g. 8) in anti-clockwise direction up to the maximum aperture (symbol
“ ”), push in and hold the knob; this will light the gas.
2. Wait for about ten seconds after the gas burner has been lit before letting go of the
knob (valve activation delay).
3. Adjust the gas valve to the desired position.
4. After use, turn the knob to the “ 0” (off ) position.
Important
■ If the burner ame should go out, the safety valve will automatically stop the gas ow.
■To re-light the burner, return the knob to closed “ 0” position (burner off), wait for at
least 1 minute and then repeat the lighting procedure.
■N.B. If your local gas supply makes it difcult to light the burner with the knob set to
maximum, set the knob to minimum and repeat the operation.

20
COOKING HINTS FOR GAS HOBS
■The burner must be chosen according to the
diameter of the pans and energy required.
■The largest can be used for boiling, to seal meat
or foods that are cooked quickly, and the smallest
for stews and sauces.
■Always ensure that you use the correct size of
saucepan.
■ For fast boiling, make sure the ame just reaches the edge of the pan. Flames going
up the side of the pan means wasted heat and the contents of the pan will take longer
to boil.
■ For optimum efciency use a wok or pan no smaller than 230 mm diameter.
■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 re, leave the pan where it is and turn off all controls.
– Place a damp cloth or correct tting lid over the pan to smother the ames.
– DO NOT use water on the re.
– Leave the pan to cool for at least 30 minutes.
WARNING - VERY IMPORTANT NOTICE
During use cooking vessels become hot. Pay special attention not to touch the hot
vessels positioned on the cooking hob especially when operating the control knobs.
