Check that the brazier rests correctly in its seat and has
no visible deposits or unburnt pellets.
Check whether the ignition plug becomes hot.
Empty and clean the brazier before relighting.
A02
Fire extinguishes abnormally
It derives from a shutdown due to lack of fuel (hopper
empty).
A03
Pellet tank temperature exceeds foreseen
safety limit.

The structure is too hot because the product has been
operating for too long at maximum power, or it is
poorly ventilated, or the air fans are faulty. When the
stove is sufficiently cold, press button B of the control
panel to cancel the alarm A03. Once the alarm is
cancelled it is possible to relight the stove normally.
