1.29 FILLING THE CONDENSATE DRAIN TRAP
On first lighting of the boiler, flue gas may come out the condensate drain; after a few minutes’
operation check that this no longer occurs. If this is the case, the drain trap is correctly filled
with condensate up to a height that does not allow the flue gas to pass.
1.30 GAS SYSTEM START-UP.
To start up the system, refer to the technical standards in force.
This divides the systems and, therefore, the commissioning operations, into three categories: new systems, modified systems, reactivated
systems.
In particular, for new gas systems:
- open windows and doors;
- avoid presence of sparks or naked flames;
- bleed all air from pipelines;
- ensure the internal system is properly sealed according to the specifications set forth by technical regulations in force.
1.31 BOILER START-UP (IGNITION)
The display leaves the factory set in Italian. To change the display language, see Par. 2.5 in the “USER” chapter, under “Changing
the display language”.
To commission the boiler (the operations listed below must only be performed by qualified personnel and in the presence of staff only):
1. check that the internal system is properly sealed according to the specifications set forth by regulations in force;
2. Ensure that the type of gas used corresponds to the boiler settings (the type of gas appears on the display on first electrical power sup-
ply);
3. check that there is no air in the gas pipe;
4. check connection to a 230V-50Hz power mains, correct L-N polarity and the earthing connection;
5. check that the intake/exhaust terminals are not obstructed and that they are installed properly;
6.
Check that the drain trap is full and that it prevents any passage of flue gas into the room
;
7. check that there are no external factors that may cause the formation of fuel pockets;
8. Carry out the flue test (Par. 3.14);
9.
Activate the Quick calibration function (if in the previous check it was necessary to change the flue parameters):
(Par. 3.13);
10. switch the boiler on and ensure correct ignition;
11. Make sure that the gas flow rate and relevant pressure values comply with those given in the manual (Par. 4.1);
12. ensure that the safety device intervenes in the event of gas supply failure and check the relative intervention time;
13. check the intervention of the main switch located upstream from the boiler and in the boiler.
Even if just one single safety check provides a negative result, do not commission the system.
