ATTENTION

SURfACES CAN BECOME VERy HOT!

During combustion, thermal energy is released that signicantly increases the heat of surfaces, doors, handles, controls, glass, exhaust
pipes, and even the front of the appliance. Avoid contact with those elements if not wearing protective clothing (protective gloves
included). Make sure children are aware of the danger and keep them away from the stove during operation.

INSTALLATION

GENERAL

The ue gas exhaust and hydraulic connections must be carried out by qualied personnel who must issue installation conformity
documentation compliant with national standards.

The installer must provide the owner or person acting for him, according to the legislation in force, with the declaration of conformity,
supplied with:

1) the use and maintenance manual of the appliance and of the system components (such as for example, the smoke ducts, chimney, etc.);

2) photocopy or photograph of the chimney plaque;

3) system booklet (where applicable).

The installer must ask to be issued with a receipt stating that the documentation has been provided, and must keep it with a copy of the technical
documentation relating to the installation.

For installation in a condominium, prior approval from the condominium's administrator must be requested.
Where required, check the exhaust gas emissions after installation. Should a sampling point be installed, it must be airtight.

COMPATIBILITY

Do not install in rooms with a re hazard. It is also forbidden to install it in living areas with the following characteristics:

1. where there are liquid fuel appliances with continuous or discontinuous operation that draw the combustion air into the room in which they
are installed.

2. where there are type B gas appliances intended for heating, with or without domestic hot water production and in adjacent and communicating
rooms.

3. where the depression measured in situ between the external and internal environment is greater than 4 Pa.

N.B.: Watertight appliances can also be installed in the cases indicated in points 1, 2 and 3 of this paragraph.

INSTALLATIONS IN BATHROOMS, BEDROOMS AND STUDIO FLATS

Installation in bathrooms, bedrooms and studio ats is only allowed for sealed or closed hearth appliances with ducted combustion air taken
from the outside.

POSITIONING AND SAFETY DISTANCES

The support surfaces and/or points must have a suitable capacity to bear the overall weight
of the appliance, accessories and coverings. If the oor is made of a combustible material,
we recommend using a non-combustible material to protect the front part from any burnt
material which might fall during routine cleaning operations. The generator must be level
to function properly. The side walls, the rear walls and the oor support surface should be
made of non-combustible material.

MINIMUM DISTANCES PELLET STOVES

Installation next to ammable or heat-sensitive materials is permitted only if the special
safety distances specied on the label at the beginning of the manual (pag.2) are
observed. If the materials are not ammable, you must keep a side and rear distance of at

least 100 mm (without the inserts). For products equipped with rear spacers, wall-mounting
installation is permitted exclusively for the rear side.

PREPARATIONS FOR MAINTENANCE

To carry out extraordinary maintenance operations on the product, it may be necessary to move it away from the adjacent walls. This must be
done by a technician authorised to disconnect the combustion product evacuation ducts and then reconnect them. For heaters connected to the
hydraulic system, the connection between the system itself and the product must be made in such a way that, when an authorised technician is
about to carry out extraordinary maintenance operations, it is possible to move the heater at least 1 metre away from the adjacent walls.

INSTALLING INSERTS

When installing inserts, access must be prevented to the internal parts of the appliance and it must not be possible to access live parts during
extraction operations.
Any wiring, for example the power cable or room probe, must be positioned so as not to be damaged during movement of the insert and must
not come into contact with hot parts. If a cavity made of combustible material is installed, we recommend taking all the safety precautions
indicated by the installation standards.

One must also bear in mind all laws and national,
regional, provincial and town council regulations in force
in the country in which the appliance has been installed,
as well as the instructions contained in this manual.

DISTANCES OF SAFETY DEVICES ACCORDING TO THE LEGISLATION

The temperature safety sensors must be on the machine at a distance no greater than 30 cm from the ow connection. Whenever the
generators lack a device, those missing can be installed on the generator ow pipe, within a distance no greater than 1m from the machine.

CHECKS WHEN STARTING FOR THE FIRST TIME

Before connecting the boiler:
a) Discharge the air from the system using the air vent in the boiler and activating the air discharge cycle from the display
b) wash all system piping thoroughly in order to remove any residues which might compromise the correct operation of certain system
components (pumps, valves, etc.).
c) The company recommends installing a magnetic lter in the generator return, to increase the operational life of the boiler, make it easier
to remove impurities and increase the overall eciency of the system.
It is also advisable to perform an inspection using appropriate instruments, to check for any stray currents that may cause corrosion.
d) Check that the ue has adequate draft, is not narrowed and that other appliances do not discharge into the ue. This is to prevent
unexpected power increases. Only after this check can the ue tting be mounted between the boiler and the ue. It is advisable to check the
ttings with pre-existing ues.

ANTICONDENSATION DEVICE MANDATORY

It is mandatory to create a suitable anti-condensation circuit, which guarantees a return temperature of the unit of at least 55°C. The anti­condensation valve, for example, is used in solid fuel boilers as it prevents the return of cold water in the exchanger. A high return temperature
improves eciency, reduces the formation of condensation from the fumes and extends the service life of the generator. The manufacturer
recommends using the 55°C model with 1” hydraulic connections.

For products with PWM* pump control, installation is considered equivalent to the creation of a suitable anti-condensation circuit in cases
where:

- the heat generator pump is the only one in the system, or

- between the heat generator and the system there is a plate heat exchanger, or
between the heat generator and the system there is a hydraulic compensator or an inertial storage device (buffer)

PELLETS AND LOADING

Pellets are made by subjecting wood shavings i.e. the rejects of pure unpainted wood from sawmills, carpentry products and products from
other activities connected to wood working and transformation, to very high pressures.
This type of fuel is fully ecological as no glues are used for its compaction. In fact, pellet compactness is guaranteed over time by a natural
substance found in wood: lignin.
In addition to being an ecological fuel, making best use of wood residue, pellets also have a series of technical advantages.
While wood has a caloric value of 4.4 kWh/kg (with 15% moisture, therefore after approximately 18 months of curing), that of pellets is 5
kWh/kg.
Pellet density is about 650 kg/m3 and water content is equal to 8% of its weight. For this reason pellets do not need to be cured to obtain a
sucient heat yield.

The pellets used must be class A1 certied according to standard ISO
17225-2 (ENplus-A1, DIN Plus or NF 444 of the following category: “High
quality NF biocombustible wood pellets”).

UNI EN 303-5 with the following characteristics: water content ≤ 12%, ash
content ≤ 0.5% and lower caloric value >17 MJ/kg (in the case of boilers).

The Manufacturer recommends using pellets with a diameter of 6mm with
its products.

PELLET STORAGE

To guarantee combustion without problems, the pellets must be kept in a
dry place.
Open the tank lid and load the pellets using a scoop.

THE USE OF EXPIRED PELLETS OR ANY OTHER MATERIAL WILL AFFECT THE FUNCTIONALITY OF YOUR
GENERATOR AND MAY LEAD TO THE TERMINATION OF THE WARRANTY AND CESSATION OF ANY ACCOMPANYING
RESPONSIBILITY ON THE PART OF THE MANUFACTURER

OPERATION AND LOGIC

IGNITION

Once the points listed previously have been checked, press key 1 for three seconds to ignite the stove. 15 minutes are available for the ignition

phase. After ignition and having reached the control temperature, the stove interrupts the ignition phase and passes to STARTING.

PREPARATION

During the start-up phase, the stove stabilises combustion, increasing it progressively, to then start ventilation and pass on to WORK.

WORK

During the work phase, the stove reaches the set power set; see following item.

SET POWER

Set the operating power from 1 to 5 (using keys 2 and 3).

Power 1 = minimum level - Power 5 = maximum level.

SET H2O

Set the boiler temperature from 65 to 80°C (using keys 4 and 5).

PUMP OPERATION

The pump is activated when the internal water temperature reaches 60°C. Since the pump is always in operation above 60°C, it is advisable

to keep a heating area always open so that the product operates in a more homogeneous manner and in order to prevent stoppages due to

overtemperature. This area is usually called “safety area”.

BURN POT CLEANING

At preset intervals, the generator cleans the burn pot, turning the machine o.

When the cleaning phase is nished, the generator will re-start automatically and continue the working phase, returning to the selected

power level.

BLOW

During the working phase, the stove has an internal timer, which after a pre-set period of time cleans the burn pot.

This phase is shown on the display, it lowers the stove power level and increases the ue gas exhaust motor for a programmed period of time.

When the cleaning phase is nished, the stove will re-start automatically and continue the working phase, returning to the selected power

level.

MODULATION and HOFF

As the water temperature approaches the set point, the boiler starts to modulate automatically bringing itself to the minimum power. If the
temperature increases beyond the set point, it will automatically switch o indicating HOFF, and will automatically go back on when the

temperature drops below the set point.

SWITCHOFF

Press key 1 for three seconds.

Once this operation has been performed, the appliance automatically enters the switch-o phase, blocking the supply of pellets.

The ue gas exhaust motor and the hot air ow motor will remain on until the stove temperature has dropped below the default
parameters.

REIGNITION

The stove can only be re-ignited automatically or manually when the cooling cycle conditions and the preset timer have been satised.

IT IS PROHIBITED TO USE THE APPLIANCE WITHOUT THE PARTITION AND/
OR FLAME GUARD SEE FIGURE ON SIDE. REMOVAL WILL COMPROMISE THE
SAFETY OF THE PRODUCT AND RESULT IN THE IMMEDIATE NULLIFICATION OF
THE WARRANTY PERIOD. IN THE CASE OF WEAR OR DETERIORATION, REQUEST
AFTERSALES ASSISTANCE TO REPLACE THE PART REPLACEMENT IS NOT
COVERED BY THE WARRANTY AS THE COMPONENT IS SUBJECT TO WEAR.

STANDBY  ADDITIONAL THERMOSTAT

N.B. : INSTALLATION MUST BE PERFORMED BY AN AUTHORISED TECHNICIAN

It is possible to control the temperature of a room adjacent to the room where the stove is positioned; simply connect a thermostat following
the procedure described in the following section (it is advisable to place the optional mechanical thermostat at a height o the ground
equal to 1.50 m). Stove operation with the external thermostat connected in the clamp TA can be dierent depending on the activation or
deactivation of the STANDBY function.

By factory default, the clamp TA is jumpered, therefore it always has closed contact (on request).

ADDITIONAL THERMOSTAT FUNCTIONING WITH

When the STANDBY function is active, the STBY icon will be on. When the contact or external thermostat is not satised (open contact /
temperature reached), the stove will switch o. As soon as the contact or external thermostat switches to the "not satised" status (closed
contact / temperature to be reached) it will re-ignite.

NB: stove operation depends on the temperature of the water inside the stove and relative factory setting restrictions. If the stove is
in HOFF (water temperature reached), any additional contact or thermostat request will be ignored.

ADDITIONAL THERMOSTAT OPERATION WITH

When the STANDBY function is not active, the STBY icon will be o.
When the contact or external thermostat is satised (open contact / temperature reached), the stove will go to minimum. As soon as the
contact or external thermostat switches to the "not satised" status (closed contact / temperature to be reached) the stove will start to work
again at the pre-set power.

NB: stove operation depends on the temperature of the water inside the stove and relative factory setting restrictions. If the stove is
in HOFF (water temperature reached), any additional contact or thermostat request will be ignored.

CHRONO

This function allows stove ignition and switch-o to be automatically programmed.
The factory setting for CHRONO is o.
The chrono allows the programming of 4 time slots per day, which can be used every day of the week.

For each time slot, it is possible to set ignition and switch-o times, specic days of application, desired temperature and set power.
Current day and time settings are essential for the correct operation of the Chrono.

Recommendations

Before using the chrono function, you must set the current day and time, so check that you have followed the points listed in the sub-chapter
“DATETIME”. To use the chrono function correctly, it must not only be programmed, but also enabled. The 4 time slots can be overlapped
using the ignition and switch-o time settings. In this way, it is possible to create a combination of time slots with dierent temperatures and
power levels, without changing the status of the stove.

N.B.: in the case of overlapping time slots, the stove will remain on until the last switch-o time.

The periodic cleaning operations, as indicated in this use and maintenance manual, must be performed with the utmost care after reading the
instructions, procedures and frequency described in this use and maintenance manual.

CLEANING THE SURFACES AND COVERING

Never use abrasive or chemically aggressive detergents for cleaning!

The surfaces must be cleaned when the generator and covering are completely cold. For the maintenance of the surfaces and metal parts,
simply use a cloth dampened with water or water and neutral soap.
Failure to comply with these instructions may damage the surfaces of the generator and cause the invalidation of the warranty.

CLEANING THE CERAMIC GLASS

Never use abrasive or chemically aggressive detergents for cleaning!

The ceramic glass must be cleaned when the glass is completely cold.
To clean the ceramic glass, simply use a dry brush and some damp newspaper dipped in ash. If the glass is very dirty, use a specic cleaning
agent for ceramic glass. Spray a small amount on a cloth and use it on the ceramic glass. Do not spray the cleaning agent or any other liquid
directly on the glass or seals!

Failure to comply with these instructions may damage the surfaces of the ceramic glass and cause the invalidation of the warranty.

CLEANING THE PELLET HOPPER

When the hopper is completely empty, disconnect the power cord of the generator, remove the residue (dust, chippings, etc.) from the empty
hopper and then ll it up.

THE PELLET HOPPER GASKETS, BURN POT AND FIRE DOOR GUARANTEE CORRECT STOVE OPERATION. THESE NEED
TO BE PERIODICALLY CHECKED BY THE USER. IF THEY ARE WORN OR DAMAGED, IMMEDIATELY REPLACE THEM.
THESE OPERATIONS MUST BE CARRIED OUT BY A QUALIFIED TECHNICIAN.

IF THE POWER CORD IS DAMAGED, IT MUST BE REPLACED BY THE SERVICE CENTRE OR BY A SIMILARLY QUALIFIED
PERSON, SO AS TO AVOID ALL RISKS.

BURN POT AND COMBUSTION CHAMBER

By means of a mechanical system, the burn pot is cleaned
automatically at preset intervals. It is however advisable to remove

any residues by means of a vacuum cleaner.

 Remove the assembly made up of the internal cone (A) and

the ash conveyor (B).

 Clean the combustion chamber and the bottom of the burn

pot completely, using a suitable vacuum cleaner.

CLEANING THE COMBUSTION CHAMBER
TUBE BUNDLE

Clean the 6 tube bundles (B) of the combustion chamber using the
brush supplied (A).

It is advisable to use a suitable vacuum cleaner during the operation.

DETAILS ON BURN POT CLEANING

To clean the burn pot, simply remove the central cone (A), lift the ame guard (B) and rotate it to remove it completely.
Perform the same operation in reverse order to re-assemble.
After having re-positioned, always make sure:

• that the cone (A) has been inserted in the correct direction (see gure);

• that the ash conveyor (B) rests on the burn pot correctly, and not on another area of the combustion chamber.

THE GENERATOR CLEANING FREQUENCY IS INDICATIVE! IT DEPENDS ON THE QUALITY OF THE PELLETS AND FREQUENCY
OF USE.
THESE OPERATIONS MAY SOMETIMES NEED TO BE PERFORMED MORE OFTEN

ROUTINE MAINTENANCE PERFORMED BY QUALIFIED TECHNICIANS

Routine maintenance must be performed at least once a year.
Given the generator uses pellets as solid fuel, it requires annual routine maintenance, which must be performed by a Qualied technician,
using only original spare parts.

Failure to comply may jeopardise safety of the appliance and invalidate the warranty conditions.
By observing the cleaning schedule reserved to the user described in the use and maintenance manual, the generator will be guaranteed
correct combustion over time, thus preventing any faults and/or malfunctions which may require subsequent technical assistance. Requests
for routine maintenance are not covered by the warranty.

DOOR, ASH DRAWER AND BURN POT GASKETS

The gaskets ensure the proper sealing of the stove and therefore its proper operation.
They must be periodically checked and immediately replaced if worn or damaged.
These operations must be carried out by a qualied technician.

CONNECTION TO THE FLUE

Annually, or in any case each time the ue pipe needs to be vacuumed and cleaned. If there are horizontal sections, the residue must be
removed to prevent it from obstructing the ow of fumes.

SHUTDOWN END OF SEASON

At the end of each season, before turning the stove o, it is advisable to completely empty the pellet hopper, removing any pellet residue and
dust with a vacuum cleaner.

IT IS ADVISABLE NOT TO DISCONNECT THE HEAT GENERATOR FROM THE ELECTRICAL POWER SUPPLY IN ORDER TO ALLOW THE PUMP
TO PERFORM THE NORMAL ANTIBLOCKING CYCLES.

Routine maintenance must be performed at least once a year.
