4.2 Startup
Before lighting the boiler
• Check the seal of the gas system.
• Check correct prefilling of the expansion tank.
• Fill the water system and make sure all air contained in the boiler and the system
has been vented.
• 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 sys-
tem.
• Make sure the gas pressure for heating is that required.
• Make sure there are no flammable liquids or materials in the immediate vicinity of
the boiler
Checks during operation
• Switch the unit on.
• Check the tightness of the fuel circuit and water systems.
• Check the efficiency of the flue and air/fume ducts while the boiler is working.
• Make sure the water is circulating properly between the boiler and the systems.
• Make sure the gas valve modulates correctly in the heating and domestic hot water
production stages.
• Check correct boiler lighting by performing various tests, turning it on and off with
the room thermostat or remote control.
• Make sure the fuel consumption indicated on the meter matches that given in the
technical data table in cap. 5.
• Make sure that with no demand for heating, the burner lights correctly on opening a
hot water tap. Check that in heating mode, on opening a hot water tap, the heating
circulating pump stops and there is regular production of hot water.
• Make sure the parameters are programmed correctly and carry out any required
customisation (compensation curve, power, temperatures, etc.).
4.3 Maintenance
Periodical check
To ensure correct operation of the unit over time, have qualified personnel carry out a
yearly check, providing for the following:
• The control and safety devices (gas valve, flow meter, thermostats, etc.) must func-
tion correctly.
• The fume exhaust circuit must be perfectly efficient.
(Sealed chamber boiler: fan, pressure switch, etc. -The sealed chamber must be
tight: seals, cable glands, etc.)
(Open chamber boiler: anti-backflow device, fume thermostat, etc.)
• The air-fume end piece and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits. For possible cleaning
do not use chemical products or wire brushes.
• The electrode must be properly positioned and free of scale.
= =
fig. 12 - Electrode positioning
• 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 circulating 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.
