About the CO₂ setting
The CO
2
setting has been set in the factory and in principle requires no
adjustments. The setting can be checked by measuring the CO
2
percentage in the
combustion gases. In case of possible disturbance of the adjustment, replacement
of the gas valve or conversion to another gas type the adjustment must be checked
and if necessary set according to the instructions below.
Always check the CO
2
percentage when the cover is open.
