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 179 ***).
3. By means of a combustion analyzer, connected to the points located on the starting accessories 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.
Case studies
A New boiler (first ignition/conversion or electrode replacement)
B Boiler with at least 500 hours of operation
4. If the combustion values do not match, perform the 100% calibration as described in the following paragraph.
5. Case A: 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.
6. Case B: if the values still do not match yet, proceed with activation of the parameter SC12 or SC13, depending on
the type of adjustment necessary (see *** '"Sc" - Combustion Control Parameters Menu' on page 185 ***)
100% calibration
IMPORTANT: DURING THE AUTOMATIC CALIBRATION PROCEDURE AND CHECK OF THE CO
FRONT CASING OF THE BOILER MUST BE CLOSED AND THE INTAKE/FUME EXHAUST DUCTS COMPLETELY
ASSEMBLED.
