further (for example when zone valves are closed), it may be best to activate stand-by mode (see section
7.5).
6.3.6 Circulator
Hydro models have a circulator and an expansion tank for direct connection of the system stove to radiators.
The circulator starts as soon as water reaches a temperature of 55° C (value that must not be lowered to
prevent formation of condensation in the stove) and works according to water temperature, even with the
stove off. A bleed screw is available on the back of the stove to remove any air in the circulator itself.
6.3.7 Brazier cleaning
During normal operation in work mode, "BRAZIER CLEANING" is activated at set intervals for a duration of
about 45 seconds. During this time, the display will show the message "BRAZIER CLEANING", stove
ventilation increases and the flame lowers in the brazier. This operation is necessary to decrease the
likelihood of ash accumulation of ash inside the brazier.
If you notice an excessive accumulation of pellets in the brazier (over half the level of the brazier
itself), immediately switch off the stove and clean the brazier. Promptly contact a service centre.
6.3.8 Shutdown
To turn off the stove, hold button 4 for a few seconds.
Once the shutdown signal has been received, the display will show a "FINAL CLEANING" message and the
fume exhaust fan will continues to run at full speed for a minimum time of about 10 minutes to ensure complete
cooling of the stove. The hot air fan will also continue to run until the stove cools down.
CAUTION: Never disconnect the power supply at this stage, as this may create problems for the stove
and compromise the subsequent phases of ignition.
6.3.9 Interruption of power supply
In the event of a brief interruption in the power supply (under 10 seconds), the stove will automatically re-start
without any alarms.
If power is lost for a longer time and the stove was in work mode, a "AL 1 - BLACK OUT" alarm will be
generated. The stove will therefore not start back up automatically, but first the alarm will need to be manually
removed.
6.3.10
Remote control.
