surfaces.
• 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 rear or the
underneath of the appliance as these areas are not designed or
intended to be touched and may contain sharp or rough edges,
that may cause injury.
• FIRST USE OF THE OVEN - it is advised to follow these
instructions:
– Furnish the interior of the oven as described in the chapter
“CLEANING AND MAINTENANCE”.
– Switch on the empty oven on max to eliminate grease from the
heating elements.
– Disconnect the appliance from the electrical power supply, let
the oven cool down and clean the interior of the oven with a
cloth soaked in water and neutral detergent; then dry carefully.
• CAUTION: Do not use harsh abrasive cleaners or sharp metal
scrapers to clean the oven door glass since they can scratch the
surface, which may result in shattering of the glass.

• Donotlinetheovenwallsorbasewithaluminiumfoil.Donotplace
baking trays or the drip tray on the base of the oven chamber.
• Do not cover the hob with aluminium foils.
• FIRE RISK! Do not store ammable material in the oven or in the
storage compartment.
• Always use oven gloves when removing the shelves and food
trays from the oven whilst hot.
• Do not hang towels, dishcloths or other items on the appliance or
its handle – as this could be a re hazard.
• Clean the oven regularly and do not allow fat or oils to build up in
the oven base or tray. Remove spillages as soon as they occur.
• Do not stand on the cooker or on the open oven door.
• Always stand back from the appliance when opening the oven
door to allow steam and hot air to escape before removing the
food.
• SAFE FOOD HANDLING: Leave food in the oven for as short
a time as possible before and after cooking. This is to avoid
contamination by organisms which may cause food poisoning.
Take particular care during warmer weather.
• WARNING: Take care NOT to lift the cooker by the door handle.
• CAUTION: The cooking process has to be supervised. A short
term cooking process has to be supervised continuously.
• The appliance must not be installed behind a decorative door in
order to avoid overheating.
• The oven accessories (e.g. oven wire rack) must be tted
correctly as indicated at page 47.
• IMPORTANT NOTE: The oven shelves (for some products one
shelf only is provided) have not been designed to place the food
directly on the shelf itself. When cooking, always place the food
in special containers or use specic materials suitable for the
food contact.
• If the power supply cable is damaged, it must be replaced only
by an authorized service agent in order to avoid a hazard.

88
• If the appliance is not tted with a supply cord and a plug, or with
other means for disconnection from the supply mains having a
contactseparationinallpolesthatprovidefulldisconnectionunder
overvoltage category III conditions, means for disconnection
must be incorporated in the xed wiring in accordance with the
wiring rules.
• WARNING: The appliance and its accessible parts become hot
during use.
Care should be taken to avoid touching heating elements.
Children less than 8 years of age shall be kept away unless

ENERGY LABELLING/ECODESIGN
• Commission delegated regulation (EU) No 65/2014 (supplementing Directive 2010/30/EU
of the European Parliament and of the Council).
• Commission regulation (EU) No 66/2014 (implementing Directive 2009/125/EC of the
European Parliament and of the Council).
Reference to the measurement and calculation methods used to establish compliance with
the above requirements:
• Standard EN 60350-1 (electric ovens).
• Standard EN30-2-1 (hobs: gas red burners).
USE OF THE APPLIANCE, ENERGY SAVING TIPS
OVEN
• Check the oven door always closes properly and the door gasket is clean and in order.
During use, open the oven door only when strictly necessary to avoid heat losses (for
some functions it may be necessary to use the oven with the door half-closed, check
the oven operating instructions).
• Turn o󰀨 the oven 5-10 minutes before the end of the theoretical cooking time to
recuperate the stored heat.
• We recommend using oven proof dishes and adjusting the oven temperature during
cooking if necessary.
HOB
GAS FIRED BURNERS
• It is important that the diameter of the pot be suitable to the potentiality of the burner
so as not to compromise the high output of the burners and therefore energy waste.
A small pot on a large burner does not give you a boiling point in a shorten amount of
time since the capacity of heat absorption of a liquid mass depends on the volume and
the surface of the pot.
• Avoid keeping a burner on without something on it (without pot).

REPLACEMENT OF THE
INJECTORS OF THE TOP BURNERS
If the injectors are not supplied they can
be obtained from the After-Sales Service.
Select the injectors to be replaced
according to the “Table for the choice of the
injectors”.
The nozzle diameters, expressed in
hundredths of a millimetre, are marked on
the body of each injector.
To replace the injectors proceed as follows:
• Remove pan supports and burners
from the cooktop.
• Using a wrench, substitute the nozzle
injectors “J” (gs. 2.5, 2.6) with those
most suitable for the kind of gas for
which it is to be used.
The burners are conceived in such a
way so as not to require the regulation
of the primary air.
ADJUSTING OF THE MINIMUM OF
THE TOP BURNERS
In the minimum position the ame must
have a length of about 4 mm and must
remain lit even with a quick turn from the
maximum position to that of minimum.
The ame adjustment is done in the
following way:
• Turn on the burner.
• Turn the tap to the MINIMUM position.
• Take o󰀨 the knob.
• With a thin screwdriver turn the screw
“A” until adjustment is correct (g. 2.7).
Normally for LPG, tighten up the
regulation screw.
