Warnings
Before any cleaning, it is necessary to
switch off the
power
to the appliance (acting on the system switch)
and wear suitable personal protection equipment (e.g.
gloves, etc.). The user must carry out only routine maintenance,
for extraordinary maintenance, contact a Service Centre
requesting service from an authorised technician. The
Manufacturer warranty does not cover damages due to negligent
or incorrect maintenance or cleaning (e.g. use of unsuitable
detergents).
Any cleaning must be carried out with the oven
completely cold and wearing adequate personal
protection devices (e.g. gloves, etc.).
When cleaning any part or accessory do NOT use:
• abrasive or powder detergents;
• aggressive or corrosive detergents (e.g. hydrochloric
or sulphuric acid, caustic soda, etc,). Caution! Never use these
substances also when cleaning the substructure/floor under the
appliance or its base;
• abrasive or sharp tools (e.g. abrasive sponges, scrapers, steel
brushes, etc.);
• steamed or pressurised water jets.
It is best to have a Service Centre perform maintenance and
inspection on the appliance at least once a year to ensure
top working and safety conditions. Keep the vents of the
electrical compartment clean and clear.
Oven cleaning
Cleaning the external steel parts
Use a cloth dampened with hot soapy water and end with rinsing
and drying.
Cleaning the glass
Clean any glass with a soft cloth and special glass detergent.
Cleaning the control panel
Clean the control panel with a soft cloth and a little detergent for
delicate surfaces.
Avoid also using very aggressive detergents that may damage
the construction material (polycarbonate).
Fig.20.
Cleaning the refractory surface
On the refractory surface, there are normally some food
residues (e.g. fat, food residues, etc.) that must be removed
frequently for health and safety reasons.
If the oven is used mainly with brick cooking, periodically remove
with a screwdriver the screws of the brick bead profile, remove the
refractory bricks from the front and suck the charred residues on the
bottom with an ash vacuum cleaner. Before repositioning the bricks,
clean them with a stiff bristle brush.
Never use liquids to clean the refractory surface.
While reinserting the bricks, be careful not to pinch your
fingers.
Replacement refractory bricks can be obtained from the
Manufacturer on request.
If the use of a natural fibre brush to eliminate food residues
from the refractory surface is not sufficient, see the chapter
“Setting the pyrolysis parameters”.

Cleaning the rusticated surface
Remove the screws of the stone block profile with a screwdriver,
remove the rusticated surface from the front and clean it with
a soft cloth soaked in hot soapy water. Avoid using abrasive or
excessively aggressive products. Finish with a thorough rinsing
and drying, then reposition it.
While reinserting the bricks, be careful not to pinch your
fingers.
Replacement rusticated surfaces can be obtained from the
Manufacturer on request.
Setting the pyrolysis parameters
Pyrolysis is a thermochemical crystallization process of food residues
that have deposited in the cooking chamber, which takes place by
bringing the oven up to 400°.
Before starting the pyrolysis, remove the coarser food residues
with a natural fibre brus
h.

A If the oven is off, touch the ON/OFF key to turn it on;
B
touch the pyrolysis key : the function start confirmation
request is displayed;
C
confirm with “OK” or cancel with .
D
after the confirmation, the icon turns green, the message
PYRO
appears in the top RH corner and the oven chamber
starts to heat up to reach 400°C - 752°F, when this tempera-
ture is reached, the function is completed (to stop the func-
tion before its completion, press the pyrolysis key
again);
E
when the oven is cold, suck any burnt residue with an ash
vacuum cleaner
Fig.22.
When the pyrolysis function starts, the room lights are turned
off to preserve them.
