If the CO2 percentage is too low, check if the air
and smoke ducts are not obstructed.
In case of gas valve replacement or difficult
ignition:
Tighten the maximum adjustment screw “A”
in a clockwise direction until you arrive to
the abutting end, than slacken for 7 turns.
Verify the boiler ignition; if the boiler goes
into lockout slacken the screw “A” again of
one turn, than retry the ignition. If the boiler
goes into lockout again, carry out the above
indicated operations until the boiler is
lighted.
At this point carry out the burner adjustment
as previously indicated.
Check the levels of CO2 often, especially with low flow 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 off 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 flue 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.
