6 Boiler stops
0 Stand-by mode
14. Check and, if necessary, correct the gas/air ratio control setting
Perform the check at full load and minimum load for all boiler models.
Only perform settings for the 230-80 and 230-120 models at minimum
load. Perform settings for the 230-160 and 230-200 models at full
load and minimum load. An electronic CO
checking and adjustment purposes. Check that the opening around
the probe is properly sealed when measurements are taken.

Set full load: press the
menu bar; if h:3 appears in the display, full load has been
set.
Now measure the CO
2
values in Table 17. If the CO
values, set the CO
percentage using the screw under the
2
cap of the V2 coil on the gas block (this can only be adjusted
on the 230-160 and 230-200 models). Check the flame
through the inspection glass (at full load): the flame must not
blow off and the burner's surface must not be red hot.
