What to do?
Possible causes:
Clean the boiler (heat exchanger and flue gas passages). Contact authorized serviceman.
Authorized serviceman can check if the flue gas sensor is not damaged. Check the flue gas sensor input on the
mainboard. Replace flue gas sensor.
Flue gas temperature is too high. Boiler stops flue gas fan. Boiler stops.

5.3. INFORMATIONS
Automatic actions:
- if meassured flue gas temp. reaches => 250°C - flue gas fan works with 70% of set value
- if meassured flue gas temp. falls to =< 210°C - flue gas fan returns to set value
- if meassured flue gas temp. reaches => 300°C - flue gas fan stops (boiler switches W4 - OFF)
- if boiler is in OFF-stage because flue gas temp. reached =>300°C, it will automatic start again when flue gas
temp. falls to <220°C and boiler measured temp. is below set boiler temp - set boiler difference
