3.2 Start-up
B
System start-up must be carried out by Qualified Personnel. Checks to be made at first lighting, and after all
maintenance operations that involved disconnecting from the systems or work on safety devices or parts of
the boiler:
Before lighting the boiler
•
Open any on-off valves between the boiler and the systems.
•
Check the tightness of the gas system, proceeding with caution and using a soap and water solution to detect any
leaks in connections.
•
Fill the water system and make sure all air contained in the boiler and system has been vented by opening the air
vent valve on the boiler and any vent valves on the system.
•
Make sure there are no water leaks in the system, domestic hot water circuits, connections or boiler.
•
Check the correct connection of the electrical system.
•
Make sure the unit is connected to an efficient earthing system.
•
Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler.
•
Vent the air from the gas pipes by means of the gas valve pressure point 1 (fig. 19).
Lighting
Open the fuel on-off valves.
Connect the power to the unit.
For the next 120 seconds the display will show FH which identifies the heating system air venting cycle.
During the first 5 seconds the display will also show the card software release.
When the message FH disappears, the boiler is ready to operate automatically whenever domestic hot water is drawn
or in case of a room thermostat demand.
A
If, after correctly carrying out the lighting procedures, the burners do not light and the message A01 appears
on the display, wait about 15 seconds and then press the RESET pushbutton. The reset controller will repeat
the lighting cycle. If the burners do not light after several of attempts, consult the "Troubleshooting" section.
A
In case of a power failure while the boiler is working, the burners will go out and relight automatically when the
power is restored.
Checks during operation
•
Make sure the fuel circuit and water systems are tight.
•
Check the efficiency of the flue and fume ducts during boiler operation.
•
Make sure the water is circulating properly between the boiler and the systems.
•
Check correct lighting of the boiler, by turning it on and off several times.
•
Make sure the fuel consumption indicated on the meter matches that given in the technical data table on cap. 4.3
"Technical data table".
•
Check the correct flow of domestic hot water with the
Δ
t given in the technical data table: do not trust measurements
made with empirical systems. The measurement should be made with special instruments and as close as possible
to the boiler, also considering the heat lost from the pipes.
•
During heating operation, make sure circulating pump stops when a hot water tap is opened, and that there is regular
production of domestic hot water.
