3.2 Commissioning
B
Checks to be done at first lighting, and after all maintenance operations that invol-
ved disconnection 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.
•
Check correct prefilling of the expansion tank (ref. sec. 4.4).
•
Fill the water system and make sure all air contained in the boiler and the system has been vented, by opening the
air vent valve on the boiler and any vent valves on the system.
•
Fill the condensate trap and check correct connection of the condensate elimination system.
•
Make sure there are no water leaks in the system, DHW circuits, connections or boiler.
•
Check correct connection of the electrical system and efficiency of the earthing system
•
Make sure the gas pressure value for heating is that required.
•
Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler
B
IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED THERE MAY BE RISK
OF SUFFOCATION OR POISONING DUE TO GAS OR FUMES ESCAPING;
DANGER OF FIRE OR EXPLOSION. ALSO, THERE MAY BE A RISK OF ELEC-
TRIC SHOCK OR FLOODING THE ROOM.
Checks during operation
•
Turn the unit on as described in sec. 1.3.
•
Check the tightness of the fuel circuit and water systems.
•
Check the efficiency of the flue and air-fume ducts during boiler operation.
•
Check the correct tightness and efficiency of the condensate removal system and trap.
•
Check correct water circulation between the boiler and systems.
•
Make sure the gas valve modulates correctly in heating and hot water production.
•
Check proper lighting of the boiler by performing various tests, turning it on and off with the room thermostat or re-
mote control.
•
Using a combustion analyzer connected to the fumes outlet of the single module (see ), check the CO
2
content in
the fumes.
•
Make sure the fuel consumption indicated on the meter matches that given in the technical data table in sec. 4.4.
•
Check the correct programming of the parameters and carry out any required customization (compensation curve,
power, temperatures, etc.).
3.3 Maintenance
IMPORTANT
B
ALL MAINTENANCE WORK AND REPLACEMENTS MUST BE CARRIED OUT
BY SKILLED QUALIFIED PERSONNEL.
Before carrying out any operation inside the boiler, disconnect the power
and close the gas cock upstream. Otherwise there may be a danger of explo-
sion, electric shock, suffocation or poisoning.
