OPERA
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. 4.3).
• 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.
• Make sure the fuel circuit and water systems are tight.
• Check the efficiency of the flue and air-fume ducts while the boiler is working.
• Check the correct tightness and functionality of the condensate elimination system and trap.
• 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 phases.
• Check proper boiler lighting by doing several 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 CO
boiler operating at max. and min. output, corresponds to that given in the technical data table for the corresponding
type of gas.
• Make sure the fuel consumption indicated on the meter matches that given in the technical data table on sec. 4.3.
• Check the correct programming of the parameters and carry out any necessary customization (compensation curve,
power, temperatures, etc.).

3.3 Maintenance

Periodical inspection
To ensure proper operation of the unit, it is necessary to have an annual inspection carried out by qualified personnel,
providing for the following:
• heat exchanger check and cleaning with suitable products if dirty or clogged
• check and possible cleaning of burner (do not use chemical products or wire brushes)
• check and cleaning of electrodes, which must be free of deposits and properly positioned
• seal and gasket check (burner, sealed chamber, etc.)
• check and cleaning of sludge remover filters and system filters
• check, cleaning and filling of condensate drain traps
• check of wiring, contacts, electrical actuators
• check and cleaning of generator air inlets and boiler room air intakes
• check and cleaning of fume evacuation duct-manifold-flue system.
• expansion tank check and prefilling
• check of correct and stable system water pressure, ensuring conformity with the required working pressure.
B
The use of automatic filling systems for reinstatement of operating conditions
must provide for adequate treatment of the water (ref. *** 'System water charac-
teristics' on page 150 ***)
• check of heating system water chemical and physical parameters (ref. *** 'System water characteristics' on page
150 ***)
