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 gas different
from the setting". The connection to the threaded coupling, having a diameter of ¾ inch, situated
on the bottom of the appliance, may be fixed or mobile using a compliant rapid pipe fitting. If
flexible piping is used, this must be in stainless steel and compliant with the norm. All the seals on
the junction threads must be in guaranteed materials certified for use with gas. Before the
installation of each single appliance it is necessary to install a cut off tap for rapid interruption of
the gas supply. It should be placed in an easily accessible position in such a way as to make it
possible to turn off the gas supply when the appliance is not being used. When the connection has
been completed, the tightness must be checked by using a leak-finder spray.
Electric connection
Before connecting the appliance, it is necessary to check that the voltage of the power supply
available corresponds to the voltage the appliance has been set for. In the event that they do not
correspond, it is necessary to modify the connection as shown in the electric diagram, if voltage
change is provided for. The junction boxes are situated behind the control panel. Furthermore, the
efficiency of the earth connection must be checked, and also that the earth conductor on the
connecting side is longer than the other conductors, and that the connecting cable has a wire bunch
adequate for the power absorbed by the appliance and is at least type H05 RN-F. As in
international provisions, before installing the appliance a unipolar device must be installed
with a contact opening of at least 3mmwhich must not interrupt the YELLOW-GREEN earth
wire. The device must be installed near the appliance, it must be approved and have adequate
capacity for the absorption of the appliance.
The appliance must be connected to the EQUIPOTENTIAL system. The connector is situated near
the end of the electric cable and is identified by a label with the symbol shown at fig.6, pag.3.
Water supply connection
Connect the water inlet piping to the distribution system following the provisions in force.
Checking gas tightness and pressure (fig. 7, pag. 4).
Before proceeding to check the pressure, it is necessary to check the tightness of the gas installation
up to the nozzle with a leak-finder spray to ensure that no damage has been done to the appliance
during transportation. Then it is possible to proceed with checking the inlet pressure, which is done
by means of a gauge for liquids, either a "U" gauge or an electronic gauge with a minimum
definition of 0.1 mbar. To carry out the reading, the screw (1) must be removed from the pressure
outlet (2) and the rubber pipe of the gauge connected. Open the gas supply valve of the appliance,
check the pressure output and close the valve. Remove the pipe of the gauge and put back the
screws correctly into the pressure outlet. The pressure valve must be within the minimum and
maximum values shown below:
