1.2 Connection to gas supply (for gas ovens only)
The oven is factory set for the type of gas spe-
cied in the order.
The label attached to the appliance indicates
which type of gas the oven has been set for.
During testing, the gas produced through combustion (CO2 and CO) should be
analysed and the nominal heat rating
should be measured to ensure that the
burners have been correctly calibrated
for the type of installation required.
Data collected should be written down and included in the technical documentation of the
appliance.
Installation instructions
The oven should be installed and commissioned by qualied technicians in compliance
with current regulations and legislation.
Gas appliances, electrical connections and rooms where the appliance is to be sited
must comply with current regulations and legislation.
The air requirement of the burners is 2 m3/h per kW of power installed.
Premises open to the public must comply with accident prevention laws and re safety
regulations. A exible metal hose can be used to connect the appliance to the gas supply; make sure you t an approved tap in a point that is easy to reach.
Make sure that the exible hose is not twisted or over-stretched or in contact with parts
of the oven subject to overheating.
Use locking clamps complying with installation regulations.
Checks to be carried out prior to installation.
Check the label on the left-hand panel of the oven to make sure that the appliance has
been set for the type of gas on your premises.
Check the label to make sure that the capacity of the gas pressure reducer is adequate
for the supply of the appliance.
Do not insert section reducers between the reducer and the appliance.
We recommend tting a gas lter between the tap and pressure regulator to ensure
perfect performance.
Connect the oven to the gas supply using a special R 1/2”
hose with an internal section of at least 16 mm.
Connection to gas supply must be carried out using rigid or
exible metal pipes. Use taps or gates with an internal diame-
ter that is greater than that of the hose.
After connecting the appliance to the gas supply make sure
that there are no leaks from joints or connections. You can
test for leaks by using soapy water or foaming agent for leak
detection.
Gas ovens should be inspected in compliance with spe-
cic regulations once a year by an authorised techni-
cian who will analyse combusted gases and check no-
minal heat rating.
The appliance can work correctly only when gas pres-
sure keeps within specic values for each gas type (see
table).
If the pressure falls outside these values, it will not be possible
to achieve optimum functioning of the appliance and for it to
be installed correctly. Should this happen, call a technician to
check your gas mains (ducts, gates and eventually pressure
reducers) then, if necessary, contact your gas provider.

For connection to a type of gas that is different from the
one specied on the rating plate, the burner/s and nozzle/s
must be replaced as follows:
• Unscrew nozzle to be replaced and replace it with the
one that corresponds to the type of gas to be used.
• Ret washer.
• Nozzles are marked in hundredths of a millimetre.
• After replacing the nozzle/s, check gas pressure.
When the appliance is connected, turn it on and check the
gas pressure.
Check gas pressure directly on the valve, as described
below:
• Unscrew screw “P” on the pressure outlet of the valve.
• Apply the pressure gauge to the pressure outlet.
• Regulate gas pressure to the values of table 2 by adju-
sting the pressure reducer outside the oven
• When the pressure is at the correct level, switch off
the oven, remove the pressure gauge and replace
screw “P”.
If the adjustment of the pressure is not sufcient, act as
follows:
• Remove the protective cap A.
• Screw to increase the pressure of the outlet gas acting
on the screw B and unscrew to decrease.
• At the end of the calibration reapply the protective
cap A.

Electric connection
The electric system, as prescribed and specied by the Standard in force, must be
equipped with an efcient ground. It is possible to guarantee the electric safety of the
appliance only in the presence of Standard electric system.
For direct connection to the mains, it is necessary to interpose a device between the
equipment and the same mains, sized for the load, that ensure its disconnection. The
contacts must have an opening distance enabling the full disconnection, in conditions
of over-voltage category III, per compliance with installation regulations.
This device also must be located in a place and in a manner to be easily accessible at
any moment by the operator.
Bring the main switch, to which the power supply cable plug will be collected, in position
0 (zero).
Have professionally qualied staff check that the plug cables section is adequate to the
power used by the appliance.
Loosen the screws xing the left side of the oven and extract it.
Connect the cable to the terminal board
following the indications on “tab 1”.
Lock the cable with the cable presser.
The power supply voltage with machine
functioning,must not be different from the
nominal voltage value by ±10%.
The equipment must be included in an equipotential system which efciency must be
checked according to that reported in the Standard.
For the connection there is a clamp, located on the frame and marked with the symbol
to which a cable with minimum section of 10 mm² must be connected.
For gas ovens, complete gas connection to the appliance before assembling the
oven side again;
for electric ovens assemble the oven side.

Fume discharge (for gas ovens only)
Ovens should only be installed in adequately ventilated rooms in compliance with installation regulations.
The oven discharge can be connected by means of a forced evacuation system (e.g. hood tted with an extractor
fan). In this case the gas supply to the appliance must be controlled by the extraction system and will be interrupted
if the extraction capacity drops below the prescribed values. When installing the appliance beneath a hood take
care to ensure that:
a) the extracted volume is greater than the volume of com-
busted gas produced (refer to current regulations);
b) the hood lter is made from a heat-resistant material
(combusted gases may reach 300°C;
c) the nal section of the gas discharge tube must be inser-
ted inside the hood;
d) following interruption of gas supply the gas will be
switched on manually.
1.8 Switching on oven and testing
Before switching on the oven, carefully check that all systems and installation of the appliance are in compliance
with current laws and with the technical and safety guidelines in this manual.
Check the following:
• The oven must be installed in a room where the temperature is over +4° C.
• The oven chamber must be empty.
• All packaging has been completely removed, including the protective lm applied to the walls of the oven.
• Vents and ventilation openings must be open and unobstructed.
• Any parts that have been removed for installation purposes must be replaced.
• The main switch must be switched on and the water and gas taps must be open.
