The foundation
Our company was founded in 1963 by the Lorenzo, Luigi and
Paolo Cuppone brothers. It immediately specialized in the
production of ovens and equipment to prepare and cook
pizza.
The constant research and experimentation of new equip-
ment that are even now the strength of our company, have
led us to design and patent the machinery and ovens that
have revolutionized the way pizza is made.

Knowing your oven
Fig. 1
Your oven can be used only to bake pizzas or similar dishes,
such as bread or focaccia and to grill vegetables.
Its main parts are:
A Control panel
B Air intakes (do not cover)
C Mobile inspection bench (burner adjustments)
D Oven door
E Door external heat-protection glass
F Removable heat protection
G Oven smoke and burnt gas discharge
H Fall protection
I Access panel for electrical components
L Circuit breaker (only USA models)
The temperature in the chamber is controlled by a board that
switches the burner on and off to keep the set temperature
constant.
Preparing to use the oven
Clean the oven and any accessories accurately, both externally
and internally, following the instructions in the dedicated
chapter rigorously.
Maintenance and cleaning - page 12.
The rst time you use the oven, we recommend you set
the temperature at 150°C - 302 °F, for at least 8 hours, with-
out placing any food inside. If the oven is fitted under a
hood (not supplied), we recommend you keep it switched on.
In this first phase, because of the humidity evaporating from
the insulating materials, the oven will give out unpleasant
smells and fumes that will gradually disappear during the
following operating cycles.
To switch the oven on and set its parameters, see page 10.
Basic notions
The first day of use is considered as a running-in period: during this time the refractory bricks and insulating material keep re-
leasing humidity until they dry out completely.
Some parts of the equipment can reach high temperatures.
We advise you to avoid touching surfaces and not to get materials either flammable or sensitive to heat near the
appliance.
Do not rest objects on the oven and especially on flue, above all if built in heat sensitive material.
Do not cover the front vents with any objects.
Take care and use personal protection equipment (i.e. gloves) when putting food into the cooking chamber or getting it out.

Some piece of advice...
• Before starting cooking, always preheat the oven: this is vital
to get good food. Pre-heating the oven must last about an
hour.
• During work, keep the refractory surfaces clean using a stiff
bristle brush.
• Passing from a type of pizza to another, wait for the oven to
stabilize.
• An excess of flour in the cooking chamber can create smoke,
smell and give the pizza an unpleasant taste.
• Clean the oven at the end of service.
Fig. 2
In the ovens, products cook thanks to the combined action of:
• radiation: the heat coming from the burner is conveyed by special deflectors placed on the sides of the cooking chamber.
The heat flow radiates the product to be cooked making it well cooked and golden;
• convection: the hot air that circulates in the chamber cooks the product evenly;
• conduction: the heat from the burner heats the refractory surfaces on which the products rest.
Unsatisfactory cooking results
If the cooking results are not as expected, try and check the following:
• temperature in the chamber either too high or too low
• incorrect preheating:
• preheating is vital to get superb results right from the first pizza;
• during preheating, the temperature has been set too high: the refractory surfaces (without pizzas) have become too hot
and burnt the first pizzas.
What is Pizzaform?
Pizzaform is a Manufacturer’s
patent. It is a special press, produced
in five models, to make pizza dough
discs up to Ø52 mm [Ø20.47 in.].
Its main features are:
- high hourly output, up to 400 piz-
zas an hour, without using special-
ized labour;
- consistent shape and thickness of
the disc of dough, without giving
up the traditional edge, obtained
thanks to the special shape of the
chrome plates;
- possibility of changing the thick-
ness of the dough discs easily.

A - Turning the oven on
Check that the gas stop-cock is open.
Fig. 4
Press the ON/OFF key.
The oven starts to warm up with the last temperature
set before switch-off.
B - Setting the preheating
Preheating must have the temperature shown in the table
on page 8 . It must be carried out without products in the
cooking chamber and takes about an hour for the oven to be
ready for cooking.
Fig. 5
With the oven on, to set the temperature, press the + key or
the - key: the display will begin to flash.
Use the + and - keys to reach the desired temperature and
wait for three flashes of the display to indicate that the setting
has been saved. The oven starts to heat up to reach the set
temperature.
During normal operation, the upper display shows the tem-
perature set in the cooking chamber while the lower display
shows the temperature detected by the temperature
probe (real temperature).
C - Starting cooking
Fig. 6
Once preheating is complete, you can start cooking and
bake the products using personal protection equipment (e.g.
gloves) and tools suitable for contact with food and made of
material resistant to high temperatures (e.g. steel).
For optimal results, always adhere to the oven capacity
declared by the Manufacturer and position the prod-
ucts to be cooked evenly in the cooking chamber.
During cooking, it is always possible to change the tempera-
ture acting as usual.
D - Switching the light on (optional)
Fig. 7
When necessary, it is possible to switch on the oven light to
check the cooking, acting on the light key.
Press the same key to switch it off.
Using the models
The oven does not turn on
A safety system checks that the oven has ignited correctly:
otherwise, three more ignition attempts are made automati-
cally, at the end of which, if the oven does not ignite yet, the
message “Err brU” appears on the displays and the burner
goes into lockdown.
How to solve the problem:
• check that the system's gas stop-cock is open ;
• press the reset (burner reset) button: the oven tries to
turn on again;
• disconnect the power plug from the socket and recon-
nect it by turning it upside down (inversion between
phase and neutral).
If after carrying out these operations the problem is not
solved, contact technical service.

Fig. 8
If you wish, you can enable a buzzer that will go off when the
set time expires, warning that cooking is complete.
ATo activate it, with the oven on, press the “timer” key.
BThe upper display starts flashing and the led under
the “reset” key turns on steadily; using the “+” or “-” keys
it is possible to set the time after which the buzzer
should sound.
CThe upper display shows digits separated by a dot, indicat-
ing the minutes on the left and multiples of 10 seconds
on the right (for example, 3.5 indicates 3 minutes and
50 seconds, the number 3 alone indicates 30 seconds).
DAfter setting, the countdown starts, during which the led
under the “reset” button flashes. At the end of the set time
a buzzer will sound to indicate the end of cooking.
Warning! the oven continues heating when the
buzzer goes off!
If you want to check how much time is left until the buzzer
sounds, press the “timer” button: the remaining time will be
shown on the upper display (e.g. 3 = 30 seconds)
To cancel the buzzer function, press the “timer” button and set
the time to “0”.
