The activation of the irreversible temperature sticker is indication that the pellets
inlet pipe of the burner has been overheated. The original condition of the sticker
can’t be restored. It is necessary to determine the cause for its activation, to
perform the relevant corrective measures and after that to replace the sticker with
new one – to be performed by a servicing technician. The activation of this sticker
might occur in cases of increased resistances in the chimney tract or decreased
chimney draught, as well as by presence of hot flue gasses in the flexible pipe
between the auger and the burner’s main module. Such situations are considered
as emergencies and are not covered by the burner’s warranty.
