7. MAKE SURE THE FRONT CASING IS CLOSED AND THE INTAKE/FUME EXHAUST
DUCTS ARE COMPLETELY ASSEMBLED
Put the boiler in heating or DHW mode for at least 2 minutes. During this period the boiler per-
forms a calibration and the flame symbol flashes on the display. The end of calibration is indi-
cated by the flame symbol steady on the display.
Check the combustion values (see following par.).
Checking the combustion values
MAKE SURE THE FRONT CASING IS CLOSED AND THE INTAKE/FUME EXHAUST DUCTS
ARE COMPLETELY ASSEMBLED.
1. Put the boiler in heating or DHW mode for at least 2 minutes. During this period if the flame
symbol flashes on the display, it means that the boiler is performing a calibration. Wait until the
flame becomes steady (end of calibration).
2. Activate the TEST mode (see *** 'TEST mode activation' on page 189 ***).
3. By means of a combustion analyzer, connected to the points located on the starting accesso-
ries above the boiler, check that the CO2 content in the fumes, with boiler working at maximum
and minimum output, matches that given in the following table.

4. If the combustion values do not match, do the 100% calibration as described in the following
paragraph.
5. If the values still do not match, do not activate other calibrations as the system needs to work
longer to be able to self-adapt.
