Warning:
Before filling the tank, make sure that at the bottom there are
no odd materials.

satisfied, the boiler goes into Modulation phase, phase in which the fuel
consumption will be minimal.
Combustion power setting
It is possible to modify the combustion power level at any time, but the
change is effective only in Run Mode. The power level ranges from 1 to
5. Increasing the power equals to a high pellet consumption.
Note: Turn off the stove in case of damage or malfunction.
COMBUSTION
The combustion is a chemical reaction in which a fuel (pellets) and an
oxidiser (air) are combined, thanks to an ignition (resistance), in order to
produce heat. They should be dosed in suitable proportions so that the
combustion can take place. Following are some examples with a de-
scription and adjustment procedure to obtain an optimal
combustion.
Automatic combustion regulation by FCS
The FCS (Fire Control System) is an automatic combu-
stion control system that always keeps the product efficiency high.
The system self
-
adjusts the dosage of fuel (pellets) and combustion air
based on the draft read by a flow meter sensor located inside the boiler..
The FCS system is therefore able to maintain an optimal flame even in
the event of imperfect conditions (aspiration, flue draft, etc.), when these
occur occasionally.
ATTENTION:
the FCS system does not compensate for structural and
continuous conditions of use and installation that are not up to standard,
or in any case do not comply with the instructions given in the following
manual regarding the quality of the pellets, flue or combustion air intake.
Therefore, it is advisable to check the quality of the flame by comparing it
to the images in the examples above, since certain conditions of use and
installation could in any case lead to machine malfunctions.
In any case, in the presence of
NOT OPTIMAL
combustion with the
automatic combustion regulation system activated, it is recommended to
contact an authorized

technician.
Calibration
(Item: Customizations
-
Service)
Note
: On models where the FCS is installed, the automatic combustion
correction range can be adjusted in the
FCS
item.
On models without the system, combustion can be adjusted manually
using the
Auger Calibration
and
Fan Calibration
functions.
Fill the auger by using the
LOAD
function. During the ignition or even in
run mode, the front door must always be kept closed.
Check TOUCH DISPLAY (pag. 9) and/or RADIO DISPLAY (pag.18)
sections for ignition, room temperature and combustion power
setting and for any further information.
OPERATING STATUS
Check Up
This phase starts as soon as the the On/Off button is pressed. During
this phase the exhaust fan goes at maximum rpm, at the same time the
system checks the probes and the safety devices.
Ignition
Once the Check Up phase is over, the system switches to the ignition
phase. The system automatically cleans the brazier, at the end of which
the cochlea loads a certain quantity of pellets and the ignition resistance
turns on. The system waits for the combustion to start, after which it
starts dosing small quantities of pellets to raise the temperature of the
fumes.
Run Mode
After the ignition, the system goes into Run Mode. During this phase the
heating fan is activated and the system operates on the set combustion
power level.
Modulation
During the working phase in Run mode, the purpose of the boiler is to
reach the boiler temperature set; when the set is
NON
-
OPTIMAL combustion, the flame is high and weak and of an oran-
ge color with a high quantity of unburnt pellets in the brazier.
NO
Pellet loading
Fill the fuel tank with wooden pellets available on the market. Open the
lid on the top and then pour the fuel in. It is recommended to close the
pellet tank lid properly.
