8 Commissioning
8.1
General
Commissioning the boiler is done for first time use, after a prolonged shut-
down (more than 28 days) or after any event that would require complete
re-installation of the boiler. Commissioning of the boiler allows the user to
review the various settings and checks to be made to start up the boiler in
complete safety.
8.2
Check-list before commissioning
1. Check that the gas type supplied matches the data shown on the
boiler's data plate.
Warning
Do not commission the boiler if the gas supplied does not match
the gas types approved for the boiler.
2. Check connection of the earth wires.
3. Check the tightness of the gas circuit from the non-return valve to the
burner.
4. Check the hydraulic circuit from the boiler's isolation valves to the
connection to the heating body.
5. Check the hydraulic pressure in the heating system.
6. Check the electricity supply connections to the various boiler
components.
7. Check the electrical connections on the thermostat and the other
external components.
8. Check the ventilation in the room in which the system is installed.
9. Check the flue gas connections.
10. Test the boiler at full load.
11. Test the boiler at part load.

Commissioning procedure
8.3.1
Checking the gas inlet
Danger
Ensure that the boiler is switched off.
1. Open the main gas valve.
2. Open the gas valve on the boiler.
3. Open the front panel.
4. Check the gas supply pressure at the pressure outlet on the gas valve
unit.
5. Check the tightness of the gas connections made after the gas valve
unit in the boiler.
6. Check the tightness of the gas pipe, including any valves, from the
non-return valve to the burner. The test pressure must not exceed
0.06 bar (0.006 MPa).
7. Vent the gas supply pipe by unscrewing the pressure outlet on the gas
valve unit. Close the outlet again when the pipe has been sufficiently
vented.
8. Check the tightness of the gas connections in the boiler.
