Ignition
Press button for a few seconds until the heat
stove starts.
The upper display will show
the word “Fan” and the lower
display the word “Acc”. During
this stage the appliance will
perform a diagnosis (about
20 seconds) on flue gas
extraction.
The next stage “LOAD
WOOD” , indicates the
pellets are filled and the
igniter will light up to start
the flame.
When the flue gas
temperature is at 50° C
(about 10 minutes) the heat
stove will enable ignition:
the top display will then
read “FirE” while the bottom
display will read “ON” .
After this stage which lasts
5 minutes approximately
the top display will
simultaneously show the
heating power (e.g. “po 6“)
and ambient temperature
(e.g. 25° ), while the
lower display will show
the system's flow water
temperature.
If the flame is not correctly ignited after 10 minutes,
the heat stove locks down: the upper display will
read “ALAR” and the lower display will flash the
words “NO ACC”: wait 10 minutes for the cooling
cycle to be completed, open the door, empty the
burn pot and proceed with a new ignition.
PLEASE NOTE:
In the event there should be repeated failed
ignitions, but the pellets are fed properly, there
might be an issue connected to breakage of the
electrical igniter. In this case, while waiting for a
technician to service it, the heat stove may be lit
manually using solid fuel cubes (fire starters).

pot together with a handful of pellets;
