4. If the measured value is outside of the values given in the table, cor
rect the gas/air ratio.
5. Using adjusting screw A, adjust the percentage of O
2
/CO
2
for the
gas type being used to the nominal value. This should always be in
side the highest and lowest setting limit.
6. The O
2
/CO
2
value set at full load has a corresponding set value at
low load (see table). Make a note of the full load value set and use
this for setting at low load.
Checking/setting values for O
2
/CO
2
at low load
1. Set the boiler to low load. Press the key several times until
appears on the display.
2. Measure the percentage of O
2
/CO
2
in the flue gases.
3. Compare the measured value with the checking values in the table.

Caution
The O

values at
full load.
The CO

values
at full load.
4. If the measured value is outside of the values given in the table, cor
rect the gas/air ratio.
