Preliminary operations
Remove the appliance from the packaging, ensure that it is intact and, if in doubt, do not use it but
contact professionally qualified personnel. After verifying that the appliance is in good conditions,
the protective film may be removed. Clean the appliance external parts carefully with warm water
and detergent using a cloth to remove all remaining residues and then dry them with a soft cloth. If
there are still traces of glue residues, remove them using a suitable solvent (e.g. acetone). Under no
circumstances use abrasive substances. After the installation the appliance has to be levelled by
regulating the adjustable feet.
Gas Connection
Before connecting the appliance, it is necessary to check that the type of gas available corresponds
to the type of gas the appliance has been set for. In the event that they do not correspond, it is
necessary to proceed as described in the paragraph Functioning with a gas type different from the
type provided for. The connection to the screwed pipe joints, which have a diameter of ½ inch and
are situated on the appliance bottom, may be fixed or mobile by using a fitting quick-coupler. If
flexible piping is used, it has to be made of stainless steel and meet the regulations in force. All the
seals on the junction threads have to be made of materials certified for gas use. In order to ensure a
quick interruption of the gas supply, before setting up each single appliance, it is necessary to install
a cut-off cock; the device has to be placed in an easily accessible position so that it is possible to
turn off the gas supply when the appliance is not used. After completing the connection, the
tightness of the cut-off cock has to be checked by using a leak-finder spray.
Electric connection
Before connecting the appliance, it is necessary to check that the voltage of the available power
supply corresponds to the voltage the appliance has been set for. If they do not correspond, it is
necessary to modify the connection as shown in the electric diagram, if voltage change is provided
for. Depending on the version, the junction boxes are situated either behind the control panel of the
top or behind the control panel of the oven (1); the latter (fig. 48 p. 16 and fig. 54 p. 17) is made
accessible by unscrewing the screws that fix the panel (2) (if present), removing it and taking out
the junction box. Furthermore, it is necessary to check that the earthing wire is efficient, that the
earth conductor on the connecting side is longer than the other conductors, that the connecting cable
has a wire bunch adequate for the power absorbed by the appliance, and that the connecting cable is
at least type H05 RN-F. As in international provisions, before setting up the appliance a
unipolar device has to be installed with a contact opening of at least 3mm that must not
interrupt the YELLOW-GREEN earthing wire. This device has to be installed near the
appliance, has to be approved, and has to have adequate capacity for the absorption of the appliance
(see technical features).
The appliance has to be connected to the EQUIPOTENTIAL system. The connector is situated near
the end of the electric cable and it is identified by a label with the symbol shown on fig. 24 (p. 12).
While using a safety thermostat for breakdown tensions, it is necessary to note what follows:
- According to the normative law in force, the leakage of electric power for these kind of
appliances can have a value of 1 mA without limitations for the maximum for each kW of
installed power. Besides, it must be noted that all the switches for breakdown to be found on
