■ Make sure that all controls are turned to zero.
■ The gas flow to the burner is controlled by the knobs on the safety taps.
■ You control the flow by turning the knob indicator to line up with the following
symbols:
– Symbol : tap closed
(burner off)
– Symbol : High (maximum)
– Symbol : Low (minimum)
■ You can control the temperature by the knob to “High” from “Minimum”.
■ 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 flame, switch that
burner off and relight using the minimum setting.
■ If after relighting the burner, the flame 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, set the gas knobs to their
closed positions and also close the cock valve on the gas bottle or the main
gas supply line.

LIGHTING THE BURNERS
(fitted with safety cut-off valve)
In order to light the burner, you must:
1 – Models fitted with electric lighter incorporated into the burner knobs:
Turn the knob fig. 12 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.
Important
■ If the burner flame should go out, the safety valve will automatically stop the
gas flow.
■ To re-light the burner, return the knob to the closed position, wait for at
least 1 minute and then repeat the lighting procedure.
■ N.B. If your local gas supply makes it difficult to light the burner with the knob
set to maximum, set the knob to minimum and repeat the operation.
■ Whenever lighting any of the burners produces an abnormal flame, switch that
burner off and relight using the minimum setting.
■ If after relighting the burner, the flame is still abnormal, turn the burner off and
contact our Customer Service Centre to obtain the nearest authorized Delonghi
Service Agent.

■ 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 fire, leave the pan where it is and turn off all con-
trols.
■ Place a damp cloth or correct fitting lid over the pan to smother the flames.
■ DO NOT use water on the fire.
■ Leave the pan to cool for at least 30 minutes.
