START-UP
The coil pre-heating phase has started and the pellets start to fall
into the brazier. The pellets ignite and take advantage of the heat
in the intake air that passes through the incandescent coil tube
PRESSURE
The cooker has completed the switching-on phase and works at
the set capacity.
WORK MODULA The desired room temperature is reached.
THE GRATE

off the cooker).

switch-off mode when the room temperature set is reached (see
the dedicated section).

not been completed yet.

When the switch-on request from ECO-STOP mode coincides
with an automatic switch-off condition (from TIMER), the cooker
turns on ensuring total cleaning of the brazier before switching to
FINAL CLEANING.
