2.4 Gas connection
B
Before making the connection, make sure the unit is arranged for operation with the type of fuel available and
carefully clean all the system gas pipes to remove any residuals or impurities that could affect proper operation
of the boiler.
The gas must be connected to the respective union (see fig. 25) in conformity with current regulations, with a rigid metal
pipe or with a continuous surface flexible s/steel tube, installing a gas cock between the system and boiler. Make sure
all the gas connections are tight.
The capacity of the gas meter must be sufficient for the simultaneous use of all the appliances connected to it. The di-
ameter of the gas pipe leaving the boiler does not determine the diameter of the pipe between the unit and the meter;
it must be chosen according to its length and pressure losses, in conformity with the current regulations.
B
Do not use the gas pipes to earth electrical appliances.
2.5 Electrical connections
Connection to the electrical grid
B
The unit's electrical safety is only guaranteed when correctly connected to an efficient earthing system exe-
cuted according to current safety standards. Have the efficiency and suitability of the earthing system checked
by professionally qualified personnel. The manufacturer is not responsible for any damage caused by failure
to earth the system. Also make sure that the electrical system is adequate for the maximum power absorbed
by the unit, as specified on the boiler dataplate.
The boiler is prewired and provided with a Y-cable and plug for connection to the electricity line. The connections to the
grid must be made with a permanent connection and equipped with a bipolar switch whose contacts have a minimum
opening of at least 3 mm, interposing fuses of max. 3A between the boiler and the line. It is important to respect the
polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in making connections to the electrical
line. During installation or when changing the power cable, the earth wire must be left 2 cm longer than the others.
B
The user must never change the unit's power cable. If the cable gets damaged, switch off the unit and have it
changed solely by professionally qualified personnel. If changing the electric power cable, use solely
“HAR
H05 VV-F” 3x0.75 mm2 cable with a maximum outside diameter of 8 mm.
Room thermostat (optional)
B
IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-FREE CONTACTS. CONNECTING 230
V TO THE ROOM THERMOSTAT TERMINALS WILL PERMANENTLY DAMAGE THE ELECTRONIC
BOARD.
When connecting time controls or a timer, do not take the power supply for these devices from their breaking
contacts Their power supply must be by means of direct connection from the mains or with batteries, depend-
ing on the kind of device.
Accessing the electrical terminal block
Undo the two screws “A” located on the top part of the control panel and remove the cover.
