Notes:
1. Parameters with more than one description vary their function and/or range in rela-
tion to the setting of the parameter given in brackets.
2. Parameters with more than one description are reset to the default value if the pa-
rameter given in brackets is modified.
3. The Maximum Heating Power parameter can also be modified in Test Mode.
4. If left at 0 the parameter Minimum fan rpm (for Low NOx versions only) does not en-
able the possibility to modify the preset rpm values for minimum and for fan start; if
set above 0, this possibility is enabled, therefore the values that will be set for the
parameter itself (P22) and for the next one (P23) will be used; while the settable
range of parameter P23 is limited (80-180), lower values between 1 and 79 can also
be set in P22: in such cases the software will always work with the real minimum
rpm, i.e. 800 rpm (which corresponds to the value 80 in the parameter).

4.2 Commissioning
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
10
has been vented.
• Make sure there are no water leaks in the system, DHW circuits, connections or boil-
er.
100
• Check correct connection of the electrical system and efficiency of the earthing sys-
tem.
60
• 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
10
IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED
B
THERE MAY BE RISK OF SUFFOCATION OR POI-
SONING DUE TO GAS OR FUMES ESCAPING; DAN-
10
GER OF FIRE OR EXPLOSION. ALSO, THERE MAY
BE A RISK OF ELECTRIC SHOCK OR FLOODING THE
ROOM.
10
Checks during operation
0 (rpm/10)
• Switch the unit on.
• Check the tightness of the fuel circuit and water systems.
120 (rpm/10) • 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
IMPORTANT
ALL MAINTENANCE WORK AND REPLACEMENTS
B
MUST BE CARRIED OUT BY SKILLED QUALIFIED
PERSONNEL.
Before carrying out any operation inside the boiler,
disconnect the power and close the gas cock up-
stream. Otherwise there may be a danger of explo-
sion, electric shock, suffocation or poisoning.
Periodical check
To ensure proper operation of the unit over time, have qualified personnel carry out a
yearly inspection, providing for the following checks:
• The control and safety devices (gas valve, flow switch, 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
