Step 1: Check on full load
Step 2: Check on low load
Step 3: Adjustment (if necessary).
Step 1: O

/ CO
2
check on full load
The O
2
or CO
2
setting is preset at the
factory to E, namely natural gas, for all
equipment units. A calibrated O
2
or CO
2
control measurement must be carried
out during commissioning.
- Ensure that the boiler is in
operation and that the heat, which
it produces, can be discharged.
Set the load of each engine
- Press the chimney sweep button for

- Calibrate the Flue Gas Analyser,
and then insert the flue gas probe
of the Flue Gas Analyser into the
measuring point of the flue gas pipe
“1” (see illustration);
- Wait for one minute and then carry
out a combustion analysis;
- Check whether the O
2
/CO
2
values
that are listed below correspond to
the measured value.
After this check has been done, once
more test the O
2
/CO
2
value at low load
(see Step 2 on page 84).
The O
2
/ CO
2
check consists of 2 steps or, if necessary, 3 steps:
5 sec.
