Dear Customer,
whilst thanking you for purchasing one of our boilers, we would like to remind you that pellet boilers are the most innovative
central heating solution that is the result of highly advanced technology with top quality processing and a simple and elegant de-
sign that is adapted to any technical room, making the environment cosy that is only obtained by the welcoming heat of a ame.
e boilers, which operate exclusively with wood pellets having a maximum diameter of 6mm, are equipped with a vertical pipe
heat exchanger.
e boilers convey heat to your system with thermal power that is adjusted according to the technical room to heat: just manually
set the water temperature of the central heating system, recommended 65 °C - 70 °C.
e boilers have been provided with sophisticated automatisms and control and safety systems that guarantee ecient and prac-
tical operation.
During rst ignitions of the boiler, the vapours emitted by the paint may cause a bad smell due to hardening. erefore, it is ad-
visable to air the room well in order to prevent prolonged persistence in front of the boiler.
IT IS prohibited to install the appliance in bedrooms or areas having explosive environments.
ATTENTION:
this warning symbol located in various points of this booklet indicates that the message it refers to must be
read carefully and understood, since failure to follow what is written can cause serious damage to the boiler and
endanger the user.
INFORMATION:
this symbol is used to highlight important information for proper boiler operation. Failure to comply with the
provisions will compromise use of the boiler and operation will be unsatisfactory.

General information
Pellet
Use of poor quality pellets or other unsuitable materials may
damage certain components of the boiler and compromise its
correct operation: this may terminate the warranty and free the
manufacturer of any liability.
Our boilers must be used with 6mm diameter, 30 mm long pellets
having maximum 6%humidity. Store the pellets away from sources
of heat, and not in humid areas or explosive environments.
It is recommended to use EN PLUS A1 certied pellets according to
ISO 17225-2
e fuel must be loaded from the upper part of the boiler, open-
ing the door, while the boiler is o.
To facilitate the procedure, complete the operation in two stages:
•Pour half the contents into the tank and wait for the pellets to
deposit at the bottom;
•Complete the operation by pouring the second half;
•Always keep the cover of the fuel tank closed aer loading
the pellets;
Since it is a central heating product, the boiler has very hot outer
surfaces. For this reason, maximum caution is recommended
during operation, in particular:
•Do not touch the ue exhaust;
•Do not carry out any type of cleaning;
•Do not discharge the ashes;
•Do not open the ash drawer;
•Keep children away;
Loading the pellet tank
•Only use wood pellets;
•Keep/store the pellets in dry places without humidity;
•Never pour pellets directly onto the brazier;
•e boiler must only be fed with high quality pellets having a 6mm diameter, as per type recommended
by the manufacturer;
•e exhaust pipes must be connected to the chimney before electrically connecting the boiler.
•e protection grid situated inside the pellet tank must never be removed;
•e technical room where the boiler is installed must have sucient air exchange;
•IT IS forbidden to operate the boiler with the door open or with the glass broken;
•Do not use the boiler as an incinerator. e boiler must only be used for its intended purpose.
Any other use must be considered improper and therefore dangerous. Do not put any objects into the
tank other than wood pellets;
•e surfaces, glass, handle and pipes overheat when the boiler is on: during operation, these parts
must be touched with care and with adequate protection;
•Keep fuel and any ammable materials at a safe distance from the boiler.
Do not remove the protection grid inside the
tank. When loading, do not let the pellet bag
come into contact with hot surfaces.

Instructions for safe and efficient use
IT IS forbidden to tamper with the safety devices. You must rst eliminate the cause that triggered the safety
device before it is possible to ignite the boiler and thus restore operation. Refer to the chapter regarding the
alarms in order to understand how to interpret each alarm that may appear on the boiler’s display.
Antifreeze function: if the probe installed inside the boiler detects water temperature below 5 °C, it automatically enables the
circulation pump in order to prevent system freezing.
Pump anti-block function: in case of prolonged inactivity of the pump, it is enabled for 10 seconds at regular intervals in order
to prevent it from blocking.
e product is classied as rapid disconnection since it has passed the tests provided for by regulation EN 303-5 Chap. 5.14.
Safety valve:
this valve intervenes
to prevent hydraulic system
overpressure.
If boiler or system pressure ex-
ceeds 2.5 bar, it discharges water
from the circuit.
Important!
e appliance’s manufacturer
shall not be held liable for any
ooding caused by the trig-
gered safety valve if it has not
been correctly tted outside
the product to a suitable col-
lection and discharge system.
Automatic vent valve: this
valve discharges air inside the
boiler.
Gearmotor: if the gearmotor
stops due to a “ALAR-NO-
ACC”or “ALAR-NO-
FIAM”warning, the boiler
continues to operate until the
ame goes out as a result of
no fuel and until it reaches
the minimum cooling level.
Electric safety: the boiler is
protected against sudden cur-
rent uctuations (e.g. lighten-
ing) by a main 4 A fuse that
is found in the control panel
situated at the back of the boil-
er close to the power supply
cable. e electronic boards
are also protected with other
fuses.
WATER
RESET
Manual reset safety thermo-
stat for the water temperature: if
the water temperature exceeds
the safety value set at 100 °C,
boiler operation stops imme-
diately and the screen will display
“ALAR-NO-FIAM”. To restart
it , you must reset the thermo-
stat manually.
Flue pressure switch: check the pres-
sure in the ue pipe. is blocks the
pellet loading auger if the discharge
is obstructed or there are signicant
backpressures, for example, in case of
wind, an open combustion chamber
door or ue extractor fault. When
the pressure switch is triggered,
“ALAR-NO-ACC”will be displayed.
Flue temperature probe: this
thermocouple detects the ue
temperature, maintaining op-
eration or stopping the boiler
when the ue gas temperature
rises above the pre-set value.
Water temperature probe: if
the water temperature ap-
proaches the blocking temper-
ature (100 °C), the probe stops
the supply of pellets.
