EXPLANATION
–
the activation of the irreversible thermosticker is indicator
for an overheating event of the pellet delivery pipe. The condition of this sticker
is not reversed to its initial condition at cooling down of the burner’s body. It is
necessary to check and make the appropriate maintenance/service actions prior
to start the burner again. This thermosticker should be changed after the
successful operation of the burner has been achieved – the check and service of
the burner is performed by authorized technician only. The activation of this
thermosticker could happen in cases like flowing hot flue gases though the
pellet’s pipe, due to increased resistance of the flue gases duct and/or decreased
draught of the chimney. In such situations the flexible hose, connecting the pellet
transport auger and the main body of the burner could be damaged as well and
could also need replacement. Such situations are abnormal and are not covered
by the warranty for the burner.
