WARNINGS BEFORE IGNITION
GENERAL WARNINGS
Remove all parts that may burn from the brazier and the glass (manual, various adhesive labels or any polystyrene).
Check that the brazier is positioned correctly and rests properly on the base.
The rst ignition may not be successful as the feed screw is empty and does not always manage to load the brazier
with the required amount of pellets in time to light the ame.
CLEAR THE FAILED IGNITION ALARM FROM THE STOVE PANEL OR APP.
REMOVE THE PELLETS LEFT IN THE BRAZIER AND REPEAT IGNITION.
If, after repeated attempts, the ame fails to ignite, despite a regular ow of pellets, check the correct positioning of the brazier, which
mustrest snugly against theslots.If no anomaly is found during this inspection, there may be a problem with the product components
or installation may not be correct.
REMOVE THE PELLETS FROM THE BRAZIER AND CONTACT AN AUTHORISED TECHNICIAN.
Do not touch the stove during the rst start-up, as it is during this phase that the paint sets. If you touch the paint,
you may expose the steel surface.
It is good practice to ensure eective ventilation in the room during the initial start-up, as the stove will emit some
smoke and smell of paint.
If necessary, touch up the paint with the spray can of the specic colour.
Do not stand close to the stove and, as mentioned, air out the room. The smoke and smell of paint will disappear after about an hour of
operation, however, they are not harmful in any case.
The product will be subject to expansion and contraction during the start-up and cooling stages, therefore slight
creaking noises may be heard. This is perfectly normal as the structure is made of laminated steel and must not be
considered a defect.
Upon rst ignition, for the rst pellet hopper, it is recommended to start the stove at maximum power so that the structure and the
smell of the paint settle more quickly.
It is recommended to install the ceramic or serpentine stone cladding after the rst successful ignition.
DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!

IGNITION
FEED SCREW ACTIVATION (FIRST IGNITION OR AFTER HOPPER EMPTYING)
Prior to rst product ignition, it is necessary to load the fuel and preload the pellets inside the feed screw for loading the fuel in the brazier.
To do this, simply press and hold the key for 10 seconds and the“feed screw
loading”will activate.
The button turns red until the phase ends or is interrupted.
To activate this function, the product must be OFF and COLD (the key
must be white and NOT ashing).
The display shows the feed screw icon and the countdown starting from the
maximum number of seconds provided for the preload cycle (e.g. 120 seconds).
The moment you start to see the pellet drop into the brazier, you
must stop loading by pressing the key.
Ignition must start with an empty brazier and not with a preload.

24-START&STOP
START&STOP
The START&STOP function switches o the product when it reaches the required room temperature and if the set temperature hysteresis
is also respected.
By pressing the button the START&STOP function is started. The icon will appear for 3”, and then go back to the previous view, where
the house near the temperature turns into the icon, as a reminder that it is activated.
When the room temperature reaches the set temperature and all the other parameters are also
respected (see the next paragraph), the equipment switches o and the display indicates the room
temperature, the current time and the STANDBY indication to indicate the standby mode, which
allows the product to turn on again as soon as the temperature drops below the set threshold or if
the intended temperature in the room increases.
The key appears steady green once the panel is activated.
Deactivate by simply pressing the button again and the house icon returns to how it was previously.
START&STOP is recommended for well-insulated rooms where even with the stove at minimum power, the temperature
will rise.
On the other hand, it is not recommended where the product is forced to switch on and o frequently (for example after
at least 1 hour of operation) because in this way, besides premature wear of the glow plug, the product never manages to
reach full eciency and temperature, thereby causing greater accumulation of ash or even condensation.

24-START&STOP
Technical Dept. - All rights reserved - Reproduction prohibited
INTERVENTION DELAY (ADJUSTMENTS OF THE START&STOP TEMPERATURE HYSTERESIS)
When the room temperature is reached, there is a waiting time for intervention to prevent the equipment from suddenly turning on/o as
the room temperature drops/rises, for example, when a door or an external window is opened. This waiting time therefore allows you to
be sure that the room temperature has actually dropped for a certain time inside the room (for example 5 minutes).
There is also a temperature threshold beyond which the equipment reacts to in the event of switching on and o and this is called
hysteresis. The NEGATIVE hysteresis identies the temperature delta, outside of which the appliance must switch back on.
The POSITIVE hysteresis identies the temperature delta, outside of which the appliance must switch o.
The hysteresis are both included in the user menu.
Example1: With the product switched on, POSITIVE hysteresis is 2°C. The room temperature is 21°C and the set temperature is 22°C. The
product will remain on until the room temperature is exceeded by 2°C and therefore, when T>23.0°C
Example2:With the product o, NEGATIVE hysteresis is 2°C. The room temperature is 19°C and the set temperature is 20°C.The product will
remain o until the set temperature drops 2°C and therefore, whenT<18.0°C
Factory settings: POSITIVE HYSTERESIS = 0
NEGATIVE HYSTERESIS = 2°
FORCED RESTART FROM START&STOP WITH BUTTON OR TEMPERATURE
As previously mentioned, when a shutdown occurs via START&STOP, the display indicates the o condition with the icon, the key
remains green and the word STAND BY is displayed.
In this display condition, the product can be turned back on as follows:
1. Wait for the room temperature to drop below the intended temperature so that the
restart occurs via START&STOP
2. Deactivate the START&STOP with the relative
button and proceed with a new start-up.
3. Change the intended temperature by pressing the
keys.
In this case, the temperature modication screen
appears. The equipment will turn on when the
setting is higher than the room temperature + the
POSITIVE hysteresis.
On the other hand, it remains in STAND BY if the
setting is lower than the room temperature + POSITIVE hysteresis and it is not possible to
switch on the device, even with the text .

24-START&STOP
WATER TEMPERATURE SETTING
For hydro stoves, it is also possible to adjust the temperature of the water in the boiler/puer/storage for possibly re-starting the stove by
pressing the keys.
In some system congurations, restarting from stand by (which happens by editing the water temperature set) occurs when the
temperature - hysteresis conditions are no longer fullled (ΔT PUFFER=10°C; ΔT STORAGETANK =10°C).
Alternatively, for restarting, it is possible to raise the H2O Temp. SET. (Puer or storage tank) or adjust the external thermostat.
In STANDBY status, pressing the keys makes it possible to scroll through the various BOILER/PUFFER/STORAGE/ROOM
temperature adjustments with the key, to possibly edit the set point, also with the stove in STANDBY and possibly turn it back on.
With the ON/OFF key, the stove can be switched o completely also in STANDBY, it can only be turned back on by pressing ON/OFF again.
ACTIVATING START&STOP WITH THE EQUIPMENT OFF
If the equipment is OFF and the START&STOP needs to be activated, the following occurs when the key is pressed:
• The stove changes from OFF to STAND BY,
• the house icon becomes and the key turns green
• In any case, the product remains o, however:
o If the previously set temperature is already lower than the room temperature, the product remains o and the on/o
key turns steady green. The stove will eventually turn on again when the room temperature drops or by modifying the
temperature setting, as seen previously, with the keys.
Under no circumstances can the product be switched on again whenTSET<ROOMT.
o If the previously set temperature is already higher than the room temperature, the equipment remains o
but the green key will start to ash to alert the user that an additional input is required to allow the product
to switch on (on/o key pressed for 2’’).
EXTRA DISPLAY
In comparison to the standard where the icon turns green, there are representations where this icon disappears to leave space for
other settings such as AUX2 – AUX3 – AUX4.
In this case, the word AUX will turn green, highlighting the fact that START&STOP is active.
In congurations where START&STOP cannot be disabled (see 5 and 6), the key is not active.
