EXCESSIVE FLUE GAS TEMPERATURE
If the flue gas temperature exceeds 300 °C because the feeding door, the door for ignition or the
ashtray door was open for too long time, then appears the text
excessive flue gas temperature

(see display)
In this case: CLOSE THE DOOR IMMEDIATELY!
If the flue gas temperature exceeds 350˚C, the flue gas fan is stopped from safety reasons and
after the temperature achieves 299 °C or less, the flue gas fan is started again. Thereby is the flue
gas fan and the flue gas sensor protected against damage.

90 °C and more. Then it comes to the state of overheating and the flue gas fan is automatically
stopped. Display flickers with the text:

DO NOT OPEN
The boiler door must not be opened. By overheating it comes to the high fuel consumption and
ecological damages.
