The product meets the values for “Green product”. The specific measured values depend on the type of connection
of the combustion air supply and flue gas exhaust to a given appliance. Therefore, when the boiler commissioning,
CO
2
value should be checked or adjusted. The gas valve is factory set to CO
2
value in the flue gas in the range
from 8.4 to 8.8%.
Max. CO value must be to 100 mg/m

converted to 3% oxygen.

1.
Use the control knob to select the symbol
and confirm by pressing the control knob. The display shows the
line “Special Operations” (chimney sweep function).
2.
Use the control knob scroll to the line “Off”, confirm by pressing the control knob and then using the control
knob select the line “ON” and confirm again.
3.
On the newly displayed line “Burner output” select “Max. heating load” using the control knob and confirm.
4.
The boiler will heat at the rated output.
5.
Unscrew the plug and insert the probe of the flue gas analyser in the flue gas measuring point (see Fig. No. 16
- Pos. 10).
6.
Check the amount of CO
2
in the flue gas which must be in the range of 8.4 to 8.8%. The recommended value
is 8.5%.
7.
Wait about 120 seconds until the boiler operation gets stabilized and check or adjust the CO
2
max. value using
the CO
2
max. regulating screw (Fig. no. 16 pos. 6).
8.
On the line “Burner output” select “Partial performance” using the control knob and confirm.
9.
Wait about 120 seconds until the boiler operation gets stabilized and check or adjust the CO
2
min. value using
the CO
2
min. regulating screw (Fig. no. 16 pos. 7).
10. When turning the adjusting screw clockwise, theCO
2
volume increases, when turning the adjusting screw
counter-clockwise, the CO
2
volume decreases.
11. Screw the cover of the gas valve adjusting screw, remove the flue gas analyser probe and screw the plug into
the flue gases measuring point (watch its tightness).
12. After the adjustment, turn off the chimney sweep function.
Note: For the boiler version K 2 L3X, the slide ø 7 mm is positioned at the output of the gas valve.
