1.27 GAS SYSTEM START-UP.
To start up the system, refer to the technical standards in force.
This divides the systems and, therefore, the commissioning oper-
ations, into three categories: new systems, modified systems, reac-
tivated 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.
1.28 BOILER START-UP (IGNITION)
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 set-
tings (the type of gas appears on the display on first connection
to the power supply, or by checking the relative parameter
“G”);
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 pas-
sage of flue gas into the room ;
7. check that there are no external factors that may cause the for-
mation of fuel pockets;
8. Perform the flue test and, if needed, set the correct value of the
parameter “F0”:
9.
Activate the quick Calibration function:
10. switch the boiler on and ensure correct ignition;
11. Check that the gas flow rate and the relative pressure values
comply with those indicated in the booklet;
12. ensure that the safety device intervenes in the event of gas sup-
ply 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.
