1. SAFETY WARNINGS
Do NOT use fuels that are different from those instructed by the manufacturer.
DO NOT use any flammable liquid to light the stove.
DO NOT light stove if glass is damaged and do not, for any reason, open the fire box door while
operating.
Only clean the glass when the stove is cold, using a specific cleaning detergent with a cotton
cloth or paper towels.
The machine must ONLY be installed by qualified personnel, certified in conformity with current
rules and regulations.
DO NOT unplug the stove if there are flames in the fire pot.
When the stove is running, pay particular attention to: the hot parts (glass, handle, etc...) they may
cause burns. Keep out of reach of children.
Remove power from the machine before any kind of maintenance or cleaning.
DO NOT place hands inside the tank during functioning.
Never throw unburnt pellets into the tank: it is a fire hazard.
Never throw pellets manually into the fire pot, especially if there are flames or hot ashes.
Unpleasant smells during functioning may be caused by the type of pellets used.
Possible noises during functioning are normal, caused by the settlement of assembled parts
Store bags of fuel at least 1 metre away from the stove, in a dry and sheltered part of the home.
DO NOT EXCEED THE PERCENTAGE OF 60% OF CORN IN THE MIXTURE WITH WOOD PELLETS.
Other finely chopped fuels (for example: olive pits, shells, etc..) can be used alone, “not mixed”
with wood pellets, but they must have a minimum diameter of 4mm (to be used only in stoves with
biomass burner).
WARNING: (see UNI10683 standard)
A minimal natural flue draught of 6-8 Pa must always be guaranteed. In case of electric power cutoff or
strong wind conditions, the natural draught avoids overheating of the stove’s electrical components and allows
the smoke to get out from the chimney instead of getting into the room.
SPECIAL WARNING
TESI Model: given its particularly reduced depth, it is advised to provide a wall anchor using a chain or
clamp to be passed via the specific holes present on the rear panel.
Improper flue draught, excessive humidity in the fuel, or an elevated ash residue in the combustion
chamber may cause THE STOVE TO NOT START AND IS NOT A RESULT OF A DEFECTIVE PRODUCT.
While the stove is running, there may be some small flames on the sides of the burner, this is NORMAL
because gas combustion occurs when in contact with warm parts.

2. PRODUCT DESCRIPTION
These stove models can be equipped with a traditional pellet burner, to burn only high quality wood pellets
that are in compliance with DIN PLUS / ö-Norm M7135 standards and their updates, or with our innovative
and patented biomass burner, capable of burning not only wood pellets of any quality (for example made of
bark and branches) but also biomass which derives from the waste of agricultural processing like corn, grape
seeds pellet, almond/hazelnut/pine nut husks, olive pits, pelletized wine pruning, etc..
An automatic cleaning system, controlled by an electronic control box, always keeps the burner clean and
obtains great efficiency and reliable use. The modulating operation varies according to the room temperature
that has been set and results in optimal environment heating. During initial start up phase (approximately 10
min.) the burner automatically fills with fuel, while the resistors, heating up, ignite the flame. Once flame has
been detected by the combustion fume sensors, normal operation begins and, thanks to the microprocessor,
fuel intake can be changed, obtaining flame modulation.
The electronic motherboard continually check temperature sensors, electric motors, and safety devices. In case
of anomalies, it will stop the stove’s functioning and signal it on the display (see alarm code paragraph).
Room heating is guaranteed by the hot air flow getting out from the stove's heat exchangers: the speed and
quantity of hot air varies according to the selected power level (from 1 to 6).
Models with pellet burner: use only high quality wood pellets, made with the tree’s trunk.
Model with biomass burner: do not exceed the 60% of corn in the mixture with wood pellets. Other
finely chopped fuels (for example: olive pits, husks, etc..) can be used alone, “not mixed” with wood
pellets: in this case they must have a minimum diameter of 4mm.
3. PELLET QUALITY
There are a variety of pellet types and qualities on the market, it is important not to choose low quality ones.
Cheap low quality pellets may contain glue, resins or chemical substances and considerably affect the
performance and safety of the product, causing chimney flue blockage, the formation of corrosive gasses,
reduced performance, releasing polluting substances into the atmosphere and incrustations on the glass.
Regulations on this matter have established that products using this type of fuel must be fed with good quality
pellets, compact and not very powdery. We recommend that you ask your retailer for a suitable type of pellet,
that are in compliance with DIN PLUS standards or M7135 standards including any updates.
The characteristics of wood pellet that should be used are: 6÷8 mm diameter, approx. 5÷20 mm length, 8% 
humidity and a heating potential of 18200 KJ/Kg.
The manufacturer does not assume any responsibility for the use of poor quality pellets and therefore
is not responsible if the stove malfunctions as a result.
Store bags of fuel at least 1 metre away from the stove, in a dry and sheltered part of the home.

TESI MODEL
TESI model warnings: considering its particularly reduced depth, it is advised to provide a wall
anchor using a chain or clamp to be passed via the specific holes present on the rear panel,
especially for models with a stone facade, as the weight of the stoves is not divided in a uniform
manner with respect to the rear metal panel. This consists of an additional safety system that the
company provides their product users with.

6. GENERAL RULES FOR CREATING THE FLUE
A few simple, yet important, rules to follow for safe constructing a flue are here explained (for further
information, please read the UNI 10683 regulation).
 Safe and correct pellet stove operations depends on the connection to a single and independent flue. No
other fireplace, stove, boiler, aspiring hoods, etc., are to be connected to the same flue (see fig.3).
This machine needs to expel products resulting from combustion via a vertical flue that has a suction
pressure minimum of 6-8 Pa, in order to constantly guarantee the expulsion of smoke, even with the
absence of electric power or adverse conditions.
The part of the flue that extrudes from the roof or remains in external contact must be covered with tiles or at
least well insulated.
 The stack must be wind resistant, with an internal section that is equal to that of the chimney, a useful
section at least twice the size of the chimney, and protect from any rain coming in.
 Any other building, plants or other obstacle that are higher than the roof must be positioned at least 3 m
away from the stack. (see fig.4).
 Whenever using two flues with parallel exits, raising the flue against the wind by one element is
recommended (see fig. 5).
The flue section must be uniform, with smooth walls that do not become more narrow, curves must be
regular and continuous.
It is recommended that the flue be equipped with a collection chamber for possible solid materials and
condensation, positioned under the smoke conduct intake, so that it is easily accessible and can be
inspected from the airtight door.

7. ELIMINATING FUMES DISCHARGE
Fumes discharge must comply with regulations in force and must therefore be brought above the roof. The
discharge tube must be made out of smooth steel and not the corrugated flexible type with silicone gaskets.
Furthermore it must be positioned externally and not in closed or semi-closed spaces. For example: garages,
narrow corridors, under closed roofs or any other place where fumes may collect in case of leaks. When
connecting the stove to a flue, make sure, with the services of a professional chimney sweep, that the flue is in
perfect condition. If this is not the case, it is absolutely mandatory to encase the existing flue with proper
material that will ensure correct functioning (see fig.7).
N.B.: the vertical portion of the pipes MUST be held in place with proper support so that the
weight will not damage the stove's flue header
TYPE OF TUBES USED FOR FLUES
Rigid painted steel tubes (at least 1.5 mm thick),or stainless steel ones (at least 0.5 mm thick), can be used.
The male/female coupling collars must be superimposed by at least 40mm.
DIAMETER OF THE FLUE TUBE
The diameter of the tubes depends on the type of system. The stove has been designed for tubes with an
80mm diameter, as shown in the table, however in some cases 100mm is advisable. If 100 mm diameter tubing
is necessary, connect it to the stove using a "T" pipe connection using a ø80 - ø100 pipe fitting. (see fig. 8)

100 mm
Recommended
Note: for each 90° curve add 1 m and for each 45° add ½ m. The lengths indicated on the table are only relevant for the vertical portion.
horizontal parts must not exceed 2 m in length.
Using a "T" fitting (see fig.8) with an inspection plug, as a connection between the stove and the flue, is
mandatory. This allows both the collection of ashes deposited inside the tubes and periodical cleaning of the
flue, without having to dismantle the tubes. Since the fumes are under light pressure, ensuring that the plug for
cleaning the flue is perfectly airtight is mandatory and it must be the same after each inspection. One must
remember put it back as it was originally and check the condition of the gasket. Verify that the various tubes are
connected properly, as instructed by the manufacturer.
It is strongly advised not to place tubes horizontally, but if absolutely necessary make sure they are placed with
an angle of at least 5°.
If a traditional flue is used it is possible to connect without the need for a "T" connection tube but you must
check that the flue has a bow for collecting ash.
Connecting directly to the stove with a horizontal track that is not more than 1 m long is recommended.
If proper tube lengths are obeyed, the flue should have a draught between 10 and 12 Pa.
Do not change flue tube size in the middle of the route and especially after a bend or a horizontal portion. Verify
that there are no constrictions in the discharge conduit or in the flue.
INSULATION AND DIAMETER OF HOLES IN WALLS OR ON THE ROOF
Once the stove's position has been established and it is verified that this place is suitable for installation, one
must drill a hole for passing flue tubes. This can vary according to the type of installation, the diameter of the
flue tube and the type of wall or roof that it must pass through.
N.B.: When passing through flammable walls or roofs, use suitable mineral insulation material (mineral wool)
with a density above 80 Kg/cm.

ENGLISH
10
END PART OF THE FLUE SYSTEM
The stack must not be installed in spaces that are closed, poorly ventilated or, in general, where fumes may
collect.
It is necessary to check that there are no flammable elements (plants, wood) or elements that could be visually
damaged (walls, windows) within 3m of the flue.
WARNING: Because pellet stove installation regulations are continually changing, always verify the
latest version of the regulations in force.
8. OXIDISING AIR INTAKE
Making an air intake hole is necessary: it guarantees an optimal quantity of oxygen for proper combustion.
Please refer to the current installation regulations (UNI 10683 and UN) to avoid health risks for those that
spend time in the room where the machine has been installed.
Bore a hole with a minimum diameter of 12 cm, and plan on using an external protection grill in order to avoid
that extraneous objects may enter, compromising the correct functioning of the equipment.
MINIMUM DISTANCES FOR THE POSITIONING OF THE AIR INTAKE
To position the air intake correctly and safely, see the
drawing (see fig.7) showing minimum distance from
any other type of opening. It is important to consider
possible wall outlets from other machines or kitchen
aspiration hoods.
SAFETY THERMOSTATS
The two safety thermostats are located at the back of the stove on the bottom. To restore stove operation, wait
for it to cool off, unscrew the protective cap and press the rearming button. Eliminate the alarm from the display
by keeping the switch-off button pressed for 3 seconds.
N.B. for the technician: if it is difficult to reach the thermostats, disconnect electricity from the appliance,
disconnect the flue discharge tube and move the stove away from the wall.

9. ELECTRICAL CONNECTIONS
All machines are equipped with electrical power supply cable, when replacing it (ex. if damaged) one must
contact one of our authorised technicians.
Before connecting to the power supply, check that:
the electric plant has been fitted with a 6A magnetothermal switch
System specifications are sufficient to satisfy what is indicated on the machine's specifications plate
(electrical power, nominal voltage, etc...)
The system has an appropriate earth connection, according to current regulations (earth connection is
mandatory by law)
No portion of the power supply cable should ever overheat 50°C above room temperature. If a direct
connection is desired, it is necessary to use an omnipolar switch, with a minimum opening between contacts
of 4mm, that has been designed for the electrical charge indicated on the plaque and must correspond to
regulations in vigour. the earth wire, brown/green, should not be interrupted by the switch! The plug or
omnipolar switch must be readily accessible once the machine has been installed
Disconnect the power supply when not using the machine for a prolonged period of time.
The manufacturer declines all responsibility if what was described above and the usual safety
regulations are not followed.

10. PRELIMINARY CONTROLS BEFORE THE FIRST START UP
MANDATORY GUIDE LINES FOR THE SAFETY OF PEOPLE; ANIMALS AND OBJECTS.
The following information is intended for the installer, to inform him some general regulations that must be
observed to correctly install the machine.
 When the machine is installed on a floor in wood, or another flammable material, it is recommended to
place insulation between the floor and the support base, with a sheet of metal at least 5 mm thick and with
a diameter that is at least 50 mm more than the area occupied by the machine in all directions. Place
mineral based insulation (mineral wool), with a nominal density that is more than 80 Kg/mc,
between the sheet metal and the floor.
 The flue tubing must not have a diameter that is less than 80 mm.
 Leave at least 50 mm between the back of the stove and the wall behind it, in order to allow proper air
intake for combustion and the heat fan.
If the machine is installed close to flammable walls, keep a safety distance of at least 30 cm on both sides
and on the back. Avoid leaving any type of flammable or combustible materials within 1m of the heat waves
from the glass window situated on the front of the machine.
During the first start-up, verify that the level of combustible load inside the burner is correct.
For the Tesi model: ensure that the stove is anchored to the rear panel by means of a chain or clamp to be
passed via its specific holes.
The first times it is started, for the first few minutes that the machine operates, there may be a slight
smell of paint: this is normal Aerate the room while the machine is operational.
SETTING THE FUEL
Before switching the appliance on, select on the display the kind of fuel you are going to use:
- Select “fuel 1” to use certified wood pellets (DIN PLUS / ö-Norm M7135) or good quality wood pellets having
a low humidity value (<13%) and a low ash residual.
- Select “fuel 2” to use non-certified wood pellets (for example made with bark and branches) having a high
humidity value (>13%) and a high ash residual.
- Select “fuel 3” to use a corn (humidity max 15%) mixed with wood pellets.
- Select “fuel 4 ” to use a biomass fuel: corn mixed with wood pellets, finely chopped (4mm minimum) or
whole olive pits, almond/hazelnut/pine nut husks ( 4mm minimum), pelletized vine pruning, cherry pits
(4mm minimum), miscanthus pellets, agripellets.
- List “fuel 5” remains available for the technician/dealer to set particular fuels that are not mentioned in the
above list.
In order to obtain a correct functioning and a high efficiency of the stove, it is necessary to select
the most suitable fuel list. All chopped fuels (olive pits, husks, etc..) must have a minimum
diameter of 4mm.
Model with biomass burner: when using corn as a fuel, it is important to mix it properly with wood
pellets to ensure a correct functioning of the stove.
DO NOT USE MORE THAN 60% OF CORN IN THE MIXTURE WITH WOOD PELLETS, otherwise the correct
stove functioning IS NOT GUARANTEED.
In order to obtain a correct mixture, it is recommended to weight each fuel on a 100g precision scale and mix
them together inside a single external container, not inside the stove tank because that would not create a
homogenous mixture.

16. CLEANING AND MAINTENANCE
To ensure correct functioning and maximum efficiency of the stove, carry out the following cleaning and
maintenance operations.
THE FOLLOWING OPERATIONS MUST BE PERFORMED WHEN THE STOVE IS COLD, AT LEAST ONCE A
WEEK AND WITHOUT ELECTRICAL POWER
BIOMASS BURNER
In order for the stove to work correctly it is important to keep the burner as clean as possible and free of any
combustion residue. At least once a week extract the flow nozzle by loosening the locking screw with the
supplied hex wrench (fig. A) and remove all of the ash and unburned residue inside the burner (fig. B) using the
flexible pipe supplied (fig. E) to connect to your vacuum cleaner. To remove any encrustation, scrape the inside
of the wheel holes (fig. C) with the tip of the supplied accessory (fig. F), remove and empty as well the
collecting container placed underneath the cast-iron wheel. Finally vacuum the air combustion duct (fig. D)
behind the burner. Having performed the cleaning, make sure to replace the front panel of the burner correctly,
screwing the locking screw until it’s limit stop.
ALWAYS KEEP THE ORIFICES OF THE BURNER. THE CLEANING FREQUENCY HAS TO BE
APPROPIATE TAKING CARE TO THE WORKING HOUR OF THE MACHINE AND TO THE
CHARACTERISTICS OF THE COMBUSTIONS RESIDUE (HIGH PERCENTAGE OF ASHES OR PRESENCE
OF DEPOSITS).

PELLET BURNER
In order for the appliance to work correctly it is important to keep the fire pot as clean as possible and free of
any combustion residue. Therefore, perform the following cleaning procedure at least once a week: remove the
fire pot by releasing it from the two supports (fig. A) and remove all the ashes from inside, especially from the
lower part inside the slot (fig. B), making sure to set it back in place correctly. Vacuum the combustion air inlet
(fig. C) using the flexible pipe supplied (fig. F), which is to be connected to your vacuum cleaner. The mesh,
that is supplied with the pellet burner, is to be positioned inside the fire pot and must be used only in case of a
strong draught in the flue.
ASHES DRAWER
Every 24 hours of operation, turn the stove off and do as follows:
- Open the door under the hearth, unscrew the nut and remove the ashes drawer with care. Empty out all the
ash taking care that there are no cinders present (fig.A).
- Carefully vacuum the ash present on the bottom to keep it from malfunctioning (fig. B).
- Place the ash drawer back into its place and tighten the wing nut until the gasket is flush.
