3.2 Start-up
B
Checks to be made at first lighting, and after all maintenance operations involving disconnection from the sys-
tems or an intervention 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 seal of the gas system, proceeding with caution and using soapy water to detect any leaks in connections.
•
Check correct prefilling of the expansion tank (ref. sec. 4.4).
•
Fill the water system and make sure that all air contained in the boiler and the system has been vented by opening
the air valve on the boiler and any air valves on the system.
•
Fill the condensate drain trap and check correct connection to the condensate elimination system.
•
Make sure there are no water leaks in the system, DHW water circuits, connections or boiler.
•
Check correct connection of the electrical system and functioning 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
Checks during operation
•
Ignite the appliance as described in sec. 1.3.
•
Check that the fuel circuit and water systems are airtight.
•
Check the efficiency of the flue and air-fume ducts while the boiler is working.
•
Check the air trap and condensate disposal system are tight and work correctly.
•
Check that the water is circulating properly between the boiler and the systems.
•
Make sure that the gas valve modulates correctly in both the heating and hot water production phases.
•
Check the proper ignition of the boiler by performing various tests, turning it on and off with the room thermostat or
remote control.
•
Using a combustion analyser connected to the boiler fume outlet, check that the content of CO
2
in the fumes, with
the boiler operating at maximum and minimum power, corresponds to the technical data table for the respective type
of gas.
•
Make sure that the fuel consumption indicated on the meter corresponds to that given in the technical data table in
sec. 4.4.
•
Check the parameters are programmed correctly and perform any required customization (compensation curve,
power, temperatures, etc.).
3.3 Maintenance
Periodical check
To keep the unit working properly over time, it is necessary to have qualified personnel make an annual check that in-
cludes the following tests:
•
The control and safety devices (gas valve, flow meter, thermostats, etc.) must function correctly.
•
The fume extraction circuit must be fully efficient.
•
The airtight chamber must be sealed
•
The air-fume end piece and ducts must be free of obstructions and leaks
•
The condensate evacuation system must be efficient with no leakage or obstructions.
•
The burner and exchanger must be clean and free of scale. When cleaning, do not use chemical products or wire
brushes.
•
The electrode must be free of scale and properly positioned.
•
The gas and water systems must be airtight.
•
The water pressure in the cold water system must be about 1 bar; otherwise, bring it to that value.
•
The circulation pump must not be blocked.
•
The expansion tank must be filled.
•
The gas flow and pressure must correspond to that given in the respective tables.
A
The boiler casing, panel and aesthetic parts can be cleaned with a soft damp cloth, possibly soaked in soapy
water. Do not use any abrasive detergents and solvents.
