USE and CARE
CAUTION:
■This appliance must be used only for the task it has explicitly been designed for,
that is for cooking foodstuffs. Any other form of usage is to be considered as
inappropriate and therefore dangerous.
■Do NOT place combustible materials or products on this appliance at any time.

GAS SUPPLY:
■The connection must be executed by an authorised person according to the relevant
standards.
■Before connecting the appliance to the gas main, mount the brass conical adaptor
onto the gas inlet pipe, upon which the gasket has been placed (figures 6-7).
Conical adaptor and gasket are supplied with the appliance (packed with conversion
kit for use with Natural gas or LPG).
■This appliance is suitable for use with Natural Gas or LPG. (Check the “gas type” stick-
er attached to the appliance).
■For Natural Gas models the gas supply is connected to the pressure regulator which
is supplied with the appliance. Adjust the regulator to obtain a test point pressure of
1 kPa with the two largest burners operating.
■For LPG models connect the gas supply directly to the appliance inlet connection and
ensure that the supply pressure is regulated to 2.75 kPa.
■The connection must be made at the rear of appliance (left or right); the pipe do not
cross the cooker.
■The terminal not used must be closed off with the plug and gasket supplied.
■IMPORTANT: To screw the connecting tube operate with 2 spanners (side figure 9).

1. After connecting the gas supply, check the piping and connections for leaks using
a soap and water solution. The presence of bubbles indicates a leak, tighten or
replace connections as appropriate.
2. Adjust the test point pressure or supply pressure to the value which is appropriate
for the gas type.
3. The operation of the appliance must be tested before leaving.
4. Turn on the appliance gas controls and light each burner individually and in combi-
nation. Check for a well defined blue flame without any yellow tipping. If any
abnormality is evident then check that the burner cap is located properly and the
injector nipple is aligned correctly.
5. Check the minimum burner setting by quickly rotating the gas control knob from
the maximum to the minimum position, the flame must not go out. If adjustment is
required carry out the “minimum burner setting adjustment" procedure described
6. If satisfacfory performance cannot be obtained isolate the appliance and contact
the local gas authority for advice and assistance.

INJECTORS REPLACEMENT
This appliance is suitable for use with natural gas or LPG (check the “gas type” sticker
attached to the appliance). A label stating the type of gas used after replacing the
injectors should replace the existing label. The nominal gas consumption and injector
size details are provided in table at page 18.
To replace the injectors it is necessary to lift the cooktop and proceed as follows:
■Remove the backguard “E” (Fig. 10).
■Remove pan supports and burners from the cooktop.
■Unscrew the two screws “B” and remove the sockets (Fig. 10).
■Unscrew the two screws “C” and remove the two side trims and joints pulling
upwards.
■Pull forwards the hobtop to release it, then lift following arrow “D” (Fig. 10).
■Hold the hobtop open by a support.
■Fully raise the adjusting air tube A (fig. 11) in order to easily reach the injector.
■Using a 7 mm A/F angled spanner, remove the injector from its housing and replace
it one according to the kind of gas (see following tables - page 16).

PRIMARY AIR ADJUSTMENT OF THE BURNERS
By operating the screw “M”, reset the air adjuster “A” according to the instructions
see “Injector table”, where the distance between injector and air adjuster is
recommended (in mm).
Before refixing the hob top, set the burners on their sites and light them in order
to check whether the flames are correct, as per the specifications given above.
In case of uncorrect flame, lift or lower the air adjuster.

MINIMUM BURNER SETTING ADJUSTMENT
In the minimum position the flame must have a length of about 4 mm and must
remain lit even when turned quickly from the maximum position to minimum.
The flame adjustment is done in the following way:
■Turn on the burner
■Tum the tap to the MINIMUM position
■Take off the knob
■With a small flat screwdriver turn the screw “F” (fig. 12) to the correct regulation.
Normally for LPG, the regulation screw is tightened up fully.

LUBRICATION OF THE GAS TAPS
If the gas tap becomes stiff, it is necessary to dismantle it carefully and clean it with petroleum
spirit. Specialist high temperature resistant grease should be used to lubricate the tap before
replacing.
The operations must be carried out by an authorised person.

LIGHTING GAS BURNERS
FITTED WITH SAFETY VALVE DEVICE AND ELECTRONIC IGNITION
■Check that the electricity is
switched on to allow spark igni-
tion.
■Make sure that all controls are
turned to zero.
■The gas flow to the burner is
controlled by a taps with safety
valve device. If the burner flame
should go out for some reason,
the safety valve will automatically
stop the gas flow. The switch of
the electric ignition is incorporat-
ed in the knobs.
■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)
■To ignite automatically, simply push the required knob down and turn it to maxi-
mum, keep the knob down until the burner lights. When the flame is lit, wait
for about ten second with the knob down (safety valve activation delay).
■You can control the temperature by the knob to “full on” from “reduced rate”.
■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 the lighting of the burners will result difficult due to peculiar condi-
tions. If when lighting any of the burners an anormal flame appears, switch
that the burner off and relight using the minimum setting.
■If the flame is still different from normal, turn the burner off and consult your
DeLonghi service agent.
■In the case of a mains failure light the burner with a match or lighted taper.

CHOICE OF BURNER
Burners Pan diameter
Auxiliary 16 cm
Semi-rapid 16 to 22 cm
Double ring up to 30 cm
Fish-burner from 12x30 to 18x40 cm
Wok max 36 cm
The burner must be chosen according to the diameter of the pans and energy
required.
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
controls.
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.

CORRECT USE OF DOUBLE-RING BURNER
■The flat-bottomed pans are to be placed directly onto the pan-support.
■To use the WOK you need to place the proper stand in order to avoid any faulty
operation of the wok burner.
