When connecting to the power mains, it is necessary to fit a plug that
complies with the standards and regulations in force.
- Insert a cable with an adequate cross-section (See TAB. 10) into the
cable raceway provided (Fig.10 item B) and then connect it to the
terminal board as illustrated (Fig.10 items F and G).
- When connection has been completed, check that the supply
voltage, with the appliance running, does not differ from the rated
value by more than
±10%.
WARNING! The flexible wire for connection to the power supply
must have characteristics at least equal to the model with rubber
insulation HO7RN-F and must have a rated section suited to the
maximum absorption
(See Tab1).
WARNING! It is essential that the oven be properly earthed.
A special earth terminal has been provided for this purpose on the
connection terminal board (Fig.10 items F and G). It is marked with
the earth symbol and the earth wire must be connected to it.
These ovens must also be included in the unipotential system. The
terminal to be used for this purpose is located at the back of the oven
(Fig.10 item E).
WARNING! The manufacturer declines any responsibility in the
event of failure to comply with the above safety precautions.
2.5.5 CONNECTING TO THE WATER SUPPLY
Connection to the water supply must be made in accordance with
local Laws and Regulations and flexible pipes for the connection to
the water supply network must comply with IEC 61770 and
subsequent modifications.
WARNING! A tap must be fitted upstream of the appliance to
shut off the water supply.
The 3/4 male gas type water filler (Fig. 10 item D) is located at the
rear of the oven. The working pressure must be between 1 and 1,5
bar.
WARNING! Higher pressures may result in situations that are
dangerous for persons and harmful for the appliance.
The appliance must be connected to a supply of soft water.
For preference, a flexible pipe should be used so as to avoid even
small pressure changes in the water supply.
Leave the water to run through the pipe before connecting the oven.
If the oven is connected to a supply of hard water this will cause
rapid calcification of the steam generator
NOTE! The manufacturer declines any responsibility in the
event of failure to comply with the above safety precautions.
2.5.6 DRAINING CONDENSATION
Fasten a rubber pipe to the connector provided (Fig.10 item C).
3 OPERATION
3.1 PRELIMINARY CONTROL OPERATIONS
WARNING! The glass will heat up when the oven is working.
Do not touch it, or you will burn yourself.
WARNING! Before commencing start-up and programming of
the oven, always check that:
all electrical and earthing connections have been properly made;
all gas and vapour exhaust connections have been properly
made;
all control operations must be carried out by specialised
technicians holding a proper license.
Do not overload the trays with items and always abide by the
minimum space required between the items and the tray above.
Before placing items inside the oven, it is advisable to set the oven to
a temperature above the envisaged set point for cooking and then to
lower the temperature to the required setting.
For more even results, we recommend avoiding the use of
temperatures above those recommended for the type of product being
baked.
3.1.1
CHECKING NOZZLES
Check that the oven (rated gas category and type) is set up for the
type and family of gas supplied. If this is not the case, convert to the
type of gas available.
The oven must be put into operation using the nozzles foreseen for
the rated thermal capacity (see technical data TAB.1).
WARNING! The valve adjustment screws must not be tampered
with: they are calibrated and sealed in the factory.
3.1.2. CHECKING THERMAL CAPACITY WITH LPG
(G30-G31)
The rated thermal capacity is achieved with the nozzle indicated in
the table (see technical data TAB.1), the air feed opening (fig.14)
must be at a distance X= see technical data TAB.1.
Operation depends on the inflow pressure available (see technical
data TAB.1):
Should the pressure be outside the values indicated above, advise
those responsible for the system and do not start up the oven until the
cause has been traced and eliminated.
3.1.3 CHECKING THE THERMAL CAPACITY WITH
METHANE GAS (G20-G25)
The rated thermal capacity is achieved with the nozzle indicated in
the table (see technical data TAB.1), the air feed opening (fig.14)
must be at a distance X= see technical data TAB.1.
Operation depends on the inflow pressure available (see technical
data TAB.1).
Should the pressure be outside the values indicated above, advise the
gas supply company and do not start up the oven until the cause has
been traced and eliminated.
NOTE! Should an additional test be required for the thermal
capacity, it can be performed using the volumetric method.
3.1.4
CHECKING THE PRIMARY AIR
The air feed opening (fig.14) must be at a distance
X= see technical data TAB.1.
3.2 ADJUSTMENT:
3.2.1 PRELIMINARY CONTROLS AND ADJUSTMENT:
The appliance leaves the factory ready-calibrated and tested for the
type of gas required, however it is always advisable to check that the
type of gas and pressures at the burner are correct. If this is not the
case, follow the procedure described in the points below:
3.2.2 CHECKING INLET PRESSURE.
The inlet pressure must be measured with a water manometer (for
example a U manometer, with a minimum resolution of 0.1 bar).
To do this, proceed as follows:
- Remove the right hand side bottom panel.
- Connect the U manometer to the gas valve.
- Turn the appliance on as indicated in the instructions.
- Measure the pressure.
- Remove the manometer.
- Tighten the seal screw again.
- Seal the valve.
N.B. The pressure must be read with the chamber operating.
3.2.3 PRELIMINARY CONTROLS AND ADJUSTMENT:
Adjust the gas valve as indicated (See Fig.11).

2: GAS INLET pressure connector
3.3 ADAPTING TO OTHER TYPES OF GAS.
WARNING! : the operations described below must only be
carried out by qualified staff authorised by MANUFACTURER
The nozzles for different types of gas are supplied in a small bag
together with the oven.
(See Fig.11)
1: GAS OUTLET pressure connector
2: GAS INLET pressure connector
Before connecting to the new gas supply, make sure that the
appliance supply pressure is the one indicated in Tab.1. This
pressure level must be guaranteed stable over a period of time.
If the infeed pressure is not within the values indicated, advise
the gas supply company and do not start up the oven until the
cause has been traced and eliminated.
