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 Eu-
ropean Parliament and of the Council).
Reference to the measurement and calculation methods used to establish compliance with
the above requirements:
• Standard EN 15181 (gas 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 recu-
perate 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 size 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 shorter 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).

9
IMPORTANT
• Cooker installation must only be carried out by QUALIFIED TECHNICIANS and in
compliance with local safety standards. Failure to install the appliance correctly could
invalidate any manufacturer’s warranty.
• The appliance must be installed in compliance with regulations in force in your country
and in observation of the manufacturer’s instructions.
• Always disconnect the appliance from the electrical supply before carrying out any
maintenance operations or repairs.
• Some appliances are supplied with a protective lm on steel and aluminium parts.
This lm must be removed before using the cooker.
