If the recorded values do not comply with those indicated in the
table, adjust accordingly as indicated below.
- Adjust the gas valve pressure regulator using a suitable slotted
screwdriver: turn clockwise to decrease the recorded CO2 value
and anti-clockwise to increase the value (the screws require
slight turning as they are very sensitive);
- Wait a few seconds until the CO2 stabilises then check the value
and repeat the procedure, if necessary.
Once the calibration procedure is completed, analyse the CO2
values at minimum power.
