2 at page 2; fig. 3 at page 3). If the supply cord is damaged, it must be replaced by the
manufacturer service agent or similarly qualified persons in order to avoid a hazard.
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 3 mm 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. 6 (p. 4).
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 this 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
the market have a tolerance for the operating tension of less than the 50%; therefore, a
suitable switch has to be chosen.
- Connect only a single appliance to each switch.
- In some cases, after long periods of inactivity or in case of a new installation, it is possible
that the appliance switches off during the setting-up. The main reason is usually the moist
produced during the isolation. The problem can be easily solved through a short pre-heating
bypassing the safety thermostat.
Checking gas tightness and pressure (fig. 7 – p. 4)
Before checking the gas 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 check the inlet pressure, which can be carried out by means of
a pressure gauge, either a "U" gauge or an electronic gauge with a minimum definition of 0,1 mbar.
In order to measure the gas pressure, remove the screw (1) from the pressure outlet (2) and connect
it to the pressure gauge pipe. Open the appliance gas supply valve, check the pressure output, and
close the valve. Remove the pressure gauge pipe and screw the screws correctly into the pressure
outlet. The pressure valve has to be within the minimum and maximum values shown down below:
If the pressure measured is not within the limits shown in the table, find out the cause. After solving
the problem, check the pressure again.
Checking the appliance power
Normally it is sufficient to check that the nozzles installed are the right ones and that the burners
function properly. If desired, it is possible to check the power absorbed by using the "Volumetric
Method", measuring the volume of gas output supplied to the appliance in time units with the aid of
a chronometer and a counter. The right comparison volume [E], measured in litres per hour (l/h) or
in litres per minute (l/min), can be obtained using the formula shown below dividing the nominal
