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
5 seconds;
- Select with “+” or “–” burner 1 or 2
(in case it is present). Press OK;
- The boiler will switch to CH power
shown on the screen.
The modulation rate can now be
adjusted between minimum 0%
and maximum 100%.
- Press the “+” button until you reach
100%;
- Press OK;
The selected engine will switch
to max power output, the screen
shows 100% (heating capacity).
- Calibrate the Flue Gas Analyser,

- 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 87). If there are
any deviations in the result, then these
must be corrected (see Step 3 on
page 88).
