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:

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).
