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 indicated diagram.
e.g. with a combustion air temperature of 20°C,
adjust the CO
2
to 12.5% (± 0.2%).
