PUTTING INTO SERVICE
Preparation for commissioning
In order to guarantee the safety and proper operation of the plant,
commissioning must be carried out by a qualified technician who is
authorized by law to do so.
Power supply
- Check that the supply voltage and frequency match yes
tele inscribed on the stamp plate of the power plant;
- check the earthing efficiency.
Filling the installation with water
Proceed as follows:
- open the tap on the flow circuit (cold water supply);
- remove the automatic vent valve cover from the pump
circulation;
- gradually open the filling valve and close the ventilation valves
on the radiators as soon as the water comes out
- close the boiler filling valve when the pressure indicated on the
hydrometer is 1 bar.
Gas supply
Proceed as follows:
- check if the type of gas supplied corresponds to the one indicated on
the stamp plate of the boiler;
- open doors and windows;
- avoid sparks and open flames;
- check the tightness of the fuel system with the boiler shut-off valve
closed and then open, and the gas valve closed (deactivated) for
10 minutes the meter (gas sensor) must not indicate any gas
passage.
Ignition procedure
Press the ON / OFF key on the control panel to turn on the
boiler:
a - the mode of operation set with the symbols and b - the
numbers show:
- in heating mode, flow temperature
- in the sanitary circuit mode, the set temperature of the domestic
horse water
The performance of certain functions is also indicated:
Deaeration cycle started
Post-circulation heating
Post-circulation domestic hot water

First start
1. Make sure that:
- the gas valve is closed;
- the electrical connection is made correctly.
In any case, make sure that the ground wire is green /
yellow is connected to a good earthing system;
- lift the automatic overpressure
valve plug with a screwdriver;
on the pressure gauge, is higher
the installation,
than 1 bar; - start the boiler (by
pressing the On / Off key) and
select the standby mode, there
are no demands, neither from
the household circuit nor from
the heating circuit.
- activate the deaeration cycle by pressing the 1 key for
10 seconds. The plant will begin a deaeration cycle of
approximately 7 minutes.
- at the end of it, check that there is no more air in the
installation; otherwise, repeat the operation;
- ventilate the radiators;
- the flue pipe must be e
adequate and without any obstacles
- make sure that all vents / windows in the room are open
(type B installation).
2. Check that the siphon contains water. If not, check it
must be refilled.
NB: If the boiler is not used for a long time, the siphon
must be refilled before starting the boiler. The siphon
acts as a hydraulic barrier, and it is dangerous to start
the boiler without water in the siphon, because the
flue gases can be released into the room.
3. Open the gas valve and check the tightness of the
connections, including those of the boiler, checking that
the measuring device does not signal any gas passage.
Eliminate any gas leaks.
4. Start the boiler by selecting with Key 1
operation (heating or domestic hot water).
Burner ignites: If this does not happen on the first try,
repeat the operation until it ignites.
Ventilation function
Pressing key 1 for 10 seconds will
start the boiler cycle which will last
approximately 7 minutes.
The function can be interrupted by
pressing the 1 key again . If
necessary, you can activate a new
cycle. Check that the boiler is also in Standby mode
(no request from the heating or sanitary circuit).
