3.10 CO2 REGULATION
During the complete calibration (Par. 3.9) it is possible to modify the CO
2
values.
In order to have an exact value of
CO
2 in the flue gas, the technician must insert the sampling probe into the well to the bottom
In case of calibration for propane air, select the analyser in LPG gas mode.
Check that theCO
2
value is the one indicated in the table (Par. 4.2), (considering a maximum tolerance of ± 0.2%), otherwise change the
value as described below:
During calibration, when the “
” symbol starts flashing (indicating the correct acquisition of the parameters) it is possible to alter the
CO
2
value by pressing the buttons 5 or 6 (
).
In this phase, the previously activated icons together with the “external connected devices presence icon” ( ) will flash on the display
and the operating temperature alternated with combustion setting is displayed.

To increase the combustion setting, press the button 5 ( ), to decrease it, press
the button 6 ( ). As the combustion setting increases, the CO
2
value decreases
and vice-versa.
Once the parameter has been altered wait for the value to be saved (displayed via the “
” symbol flashing).
To confirm the value set, press “ ” followed by “ ” again in order to go to the next calibration.
