Emissions test mode for testing flue gas should only
be activated by your flue gas inspector during the
annual inspection.
Whenever possible, carry out emissions testing during
the heating season.
Activating emissions test mode
Note
It is not recommended to manually start the fuel cell
module immediately before the emissions test.
Depending on the heat-up condition of the DHW cylin-

no guarantee that the fuel cell module will operate long
enough to carry out the emissions test. The start
phase may take up to 2.5 hours.
