LIGHTING GAS BURNERS
I Check that the electricity is switched on to allow spark ignition.
I Make sure that all controls are turned to zero.
I The gas flow to the burner is controlled by a tap incorporating a safety cut-off
valve. 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
incorporated in the knobs.
I You control the flow by turning the knob indicator to line up with the following
symbols:
– Symbol
: tap closed (burner off)
– Symbol
– Symbol
: High (maximum)
: Low (minimum)
To light one of the gas burners, follow the procedure LIGHTING GAS BURNERS on
page 16.
To reduce the gas flow to minimum, rotate the knob further anti-clockwise to point
the indicator towards the small flame symbol.
The maximum aperture position permits rapid boiling of liquids, whereas the minimum
aperture position allows slower warming of food or maintaining boiling conditions
of liquids.
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 closed positions.
N.B. 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 GAS BURNERS (FITTED WITH SAFETY CUT-OFF VALVE)
In order to light the burner, you must:
1 – Turn the knob fig. 17 in anti-clockwise direction up to the maximum aperture,
push in and hold the knob; this will light the gas. If there is no mains electrical
supply, bring a lighted match close to the burner.
2 – Wait about ten seconds after the gaslights before releasing the knob (starting
time for the valve).
3 – Adjust the gas valve to the desired position.
If the burner flame should go out, the safety valve will automatically stop the gas
flow.
To re-light the burner, first turn the oven control knob to position "0", wait for at least
1 minute and then repeat the lighting procedure.
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.
COOKING HINTS FOR GAS HOBS
I
I
The burners are different sizes, and can be used in different ways.
The largest can be used for boiling, to seal meat or foods that are cooked quickly,
and the smallest for stews and sauces.
I
I
Always ensure that you use the correct size of saucepan.
For fast boiling, make sure the flame 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.
I
For optimum efficiency use a wok or pan no smaller than 230mm diameter.

Cleaning and Maintenance
GENERAL ADVICE
ꢀ Before you begin cleaning you must ensure that the hob is switched off.
ꢀ It is advisable to clean when the appliance is cold and especially when cleaning the
enamelled parts.
ꢀ All enamelled surfaces have to be washed with soapy water or some other non-abrasive
product with a sponge and are to be dried preferably with a soft cloth.
ꢀ Avoid leaving alkaline or acid substances (lemon juice, vinegar etc.) on the surfaces.
ꢀ Do not use cleaning products with a chlorine or acidic base.
WARNING
When correctly installed, your product meets all safety requirements laid down for
this type of product category. However special care should be taken around the un-
derneath of the appliance as this area is not designed or intended to be touched
and may contain sharp or rough edges, that may cause injury.
GLASS SURFACE
ꢀ Remove spillages and other types of incrustations by using only specific
products which do not contain abrasives or chlorine-based acids.
ꢀ If you use a detergent, please make sure that it is not abrasive or scouring.
Abrasive or scouring powders can damage the glass surface of the hob.
ꢀ All traces of the cleaner must be removed with a damp cloth.
ꢀ Dust or food particles can be removed with a damp cloth.
ꢀ Dust, fat and liquids from food that has boiled over must be removed as soon
as possible.
ꢀ If they are allowed to harden they become increasingly difficult to remove. This
is especially true in the case of sugar/syrup mixtures which could permanently
damage the surface of the hob if left to burn on it.
ꢀ Avoid using a knife or other sharp utensil as these may damage the glass
surface.
ꢀ Do not use steel wool or an abrasive sponge which could scratch the surface
permanently.
ꢀ Do not put articles on the hob which can melt: i.e plastic, aluminium foil, sugar,
sugar syrup mixtures etc.
Do not use harsh abrasive cleaners or sharp metal scrapers to clean the glass
since they can scratch the surface, which may result in shattering of the glass.
18
ENAMELLED PARTS
ꢀ All the enamelled parts must be cleaned with a sponge and soapy water only or other
non-abrasive products.
ꢀ Dry preferably with a soft cloth.
ꢀ If acid substances such as lemon juice, tomato conserve, vinegar etc. are left on the
enamel for a long time they will etch it, making it opaque.
STAINLESS STEEL SURFACES
ꢀ Stainless steel parts should be rinsed with water and dried with a microfibre or soft
cloth.
ꢀ For persistent dirt, use specific non-abrasive products available commercially or a
little hot vinegar.
GAS TAPS
ꢀ Periodic lubrication of the gas taps must be carried out by specialist personnel only.
ꢀ In the event of operating faults in the gas taps, call the Service Department.
CONTROL KNOB/S
ꢀ The control knob/s may be removed for cleaning but care should be taken not to
damage the seal.
19
IMPORTANT WARNING
NEVER unscrew the burner plate fixing screws (fig. 22).
The burner plates can be removed ONLY by an authorised service agent.
Damage to the appliance will occur if not observing this condition and this may
result in serious injury to the user.
The manufacturer declines every responsibility for any inconvenience resulting
from the inobservance of this condition.
