instruction manual of the boiler, including verification of the CO
and CO
2
concentration in the flue gases, their temperatures and
the average temperature of the water in the boiler.
The values in Tab. G are refer to 12.5% CO

by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.
WARNING
Check the correct working of the adjustment, com-
mand and safety devices.
WARNING
The combustion air is sucked from outside, there-
fore, there can be sensitive temperature varia-
tions that can influence the percentage value of
the CO
2
. It is advisable to adjust the CO
2
accord-
ing to the diagram.
For example: with an combustion air temperature
of 20°C, adjust the CO
2
to 12.5% (± 0.2%).
