is used within a non domestic environment i.e. a semi
commercial, commercial or communal environment.
Read the instructions carefully before installing and using
the appliance.
• This appliance has been designed and manufactured in
compliance with the applicable standards for the household
cooking products and it fullls all the safety requirements shown in
this manual, including those for surface temperatures.
Some people with sensitive skin may have a more pronounced
temperature perception with some components although these
parts are within the limits allowed by the norms.
The complete safety of the appliance also depends on the correct
use, we therefore recommend to always pay a extreme attention
while using the product, especially in the presence of children.
• After having unpacked the appliance, check to ensure that it is not
damaged and that the oven door closes correctly.
In case of doubt, do not use it and consult your supplier or a
professionally qualied technician.
• Packing elements (i.e. plastic bags, polystyrene foam, nails,
packing straps, etc.) should not be left around within easy reach of
children, as these may cause serious injuries.
• Some appliances are supplied with a protective lm on steel and
aluminium parts. This lm must be removed before using the

• 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.

77
• 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.
• Do not line the oven walls or base with aluminium foil. Do not
place 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 45.
• If the power supply cable is damaged, it must be replaced only
by an authorized service agent in order to avoid a hazard.
• If the appliance is not tted with a supply cord and a plug, or
with other means for disconnection from the supply mains

88
having a contact separation in all poles that provide full
disconnection under 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
continuously supervised.

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 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).

a bracket to the rear of the appliance and securely xing it to the wall.
To t the anti-tilt bracket:
1. After you have located where the cooker is to be positioned, mark on the wall the
place where the 2 screws of the anti-tilt bracket have to be tted. Please follow the
indications given in g. 1.9.
2. Drill two 8 mm diameter holes in the wall and insert the plastic plugs supplied.
Important! Before drilling the holes, check that you will not damage any pipes
or electrical wires.
3. Loosely attach the anti-tilt bracket with the 2 screws supplied.
4. Move the cooker to the wall and adjust the height of the anti-tilt bracket so that it can
engage in the slot on the cooker’s back, as shown in g. 1.9.

VENTILATION REQUIREMENTS
The appliance must be installed in compliance with applicable local regulations
concerning ventilation and the evacuation of exhaust gases.
Intensive and prolonged use may require extra ventilation, e.g. opening a window,
or more e󰀩cient ventilation increasing the mechanical suction power if this is tted.
CHOOSING SUITABLE SURROUNDINGS
The room where the gas appliance is to be installed must have a natural ow of air so
that the gas can burn (in compliance with applicable local regulations).
The ow of air must come directly from one or more openings made in the outside walls
with a free area of at least 100 cm2(or refer to applicable local regulations).
The openings should be near the oor and preferably on the side opposite the exhaust for
combustion products and must be made so that they cannot be blocked from either the
inside or the outside.
When these openings cannot be made, the necessary air can come from an adjacent
room which is ventilated as required, as long as it is not a bed room or a danger area (in
compliance with applicable local regulations).
In this case, the kitchen door must allow the passage of the air.
There must be a distance of at least 650mm between the hob of the cooker and any
wall cupboard or extractor hood positioned immediately above (see g. 1.10).
DISCHARGING PRODUCTS OF COMBUSTION
Extractor hoods connected directly to the outside must be provided, to allow the products
of combustion of the gas appliance to be discharged (g. 1.10).
If this is not possible, an electric fan may be used, attached to the external wall or the
window; the fan should have a capacity to circulate air at an hourly rate of 3-5 times the
total volume of the kitchen (g. 1.11).
The fan can only be installed if the room has suitable vents to allow air to enter, as
described under the heading “Choosing suitable surroundings”.
