Instructions for the installer
GENERAL WARNINGS
The place where the oven is installed must have the following environmental characteristics:
be dry, the temperature and relative humidity of the room in which it is to be installed must not
exceed the values indicated in technical data table;
adequately distant water sources;
ventilation and lighting suitable, compliant with the hygiene and safety standards required by
current laws.
THE OVEN MUST NOT BE INSTALLED NEAR FLAMMABLE MATERIALS (WOOD,
PLASTIC, FUELS, GAS, ETC.). ALWAYS AVOID THE CONTACT OF FLAMMABLE
OBJECTS WITH THE HOT SURFACES OF THE OVEN. ALWAYS ENSURE THE FIRE
SAFETY CONDITIONS. KEEP A FREE SPACE AROUND THE OVEN OF AT LEAST 30 CM.
MODULE MOVEMENT AND POSITIONING
Remove the conveyor belt.
Use a forklift truck or a pallet truck with adequate capacity.
Raise the hoods and insert the forks, suitably covered with
soft material to prevent damage, into the cooking
chamber, through the tunnel inlet or outlet (Fig.1).
Position the oven at the corners of the base (Fig.2).

STACKING
MAXIMUM NUMBER OF OVENS THAT CAN BE STACKED: 3
MODULE POSITIONING
The gas appliance is type A₂/B₂₂ for which no connection to a chimney or device is installed that
discharges the fumes outside.
It is necessary to place the oven under an extractor hood.
EXTRACTOR HOOD
EXTERNAL EXHAUST

7
ELECTRICAL CONNECTION
Check that the power supply voltage, the frequency and the power of the system are compatible with the
values indicated both in the technical features and on the plate affixed to the back of the oven.The
characteristics of the power supply socket must be compatible with the plug installed on the cable.
THE ELECTRICAL CONNECTION OF THE OVEN TO THE POWER SUPPLY NETWORK
MUST ONLY BE PERFORMED BY AN AUTHORISED TECHNICIAN (ELECTRICIAN) IN
POSSESSION OF THE TECHNICAL-PROFESSIONAL REQUIREMENTS IMPOSED BY
THE APPLICABLE RULES IN THE COUNTRY OF USE OF THE OVEN. REQUEST
ISSUING OF A DECLARATION OF CONFORMITY OF THE INTERVENTION
PERFORMED.
FOR DIRECT CONNECTION TO THE NETWORK, IT IS NECESSARY TO USE A DEVICE
WITH AN OPENING BETWEEN THE CONTACTS THAT ENSURES COMPLETE
DISCONNECTION IN THE CONDITIONS OF THE OVERVOLTAGE CATEGORY III, IN
ACCORDANCE WITH THE INSTALLATION RULES.
To connect the machine to the electrical network, proceed as follows:
fit a normalised and polarised plug at the other end of the cable (the distinction between phase and
neutral must be unequivocal).
WITH ELECTRICAL CONNECTION COMPLETED, THE AUTHORISED TECHNICIAN
(ELECTRICIAN) MUST ISSUE A DECLARATION THAT CERTIFIES THE CONTINUITY
MEASUREMENT OF THE EQUIPOTENTIAL PROTECTION CIRCUIT.
THE APPLIANCE IS TO BE SUPPLIED THROUGH A RESIBASIC CURRENT DEVICE
(RCD) HAVING A RATED RESIBASIC OPERATING CURRENT NOT EXCEEDING 30 MA.

SAFETY THERMOSTAT
The safety thermostat is located inside the ventilation chamber immediately adjacent to the burners. This
is calibrated at 427°C and is manual reset. If a temperature equal to or greater is detected, the power
supply to the whole oven is removed and the gas is closed accordingly.
To restart the oven, a qualified technician must intervene who will check the reason for this anomaly and
can then reset it manually only by opening the panel in the technical compartment (system door). See the
figure below where the safety thermostat is highlighted.
The position of the red reset button is indicated by the arrow.
Reset is not possible until the chamber temperature has dropped below 427°C.
Since the safety thermostat only intervenes where there are serious malfunctions,
carefully check the oven’s working and repair if necessary before starting up the
oven again.
