If the CO2 percentage is too low, check if the air
and smoke ducts are not obstructed.
Check the levels of CO2 often, especially with low ow rates. They refer to the boiler with a closed combustion chamber.

3) Conclusion of the basic calibrations
- once the CO
2
values at minimum and maximum output
have been checked and any adjustments have been made
(sections 1-2):
- disable the timed “calibration” function by switching o󰀨 the
main switch.
For proper operation, the CO
2
values must be
calibrated with particular attention, observing
the values indicated in the table.
- close the ue gas inspection sample points of the intake and
exhaust terminal
- check that there are no gas leaks.
If they are not obstructed, check if the burner and/or the
exchanger (aluminium sections) are well cleaned.
