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 boiler.
DO NOT light boiler if glass is damaged and do not, for any reason, open the fire box door while
operating.
Only clean the glass and painted parts with boiler cold, using a specific cleaning detergent, NOT
abrasive or corrosive, with a cotton cloth.
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.
Take care when the boiler is functioning: 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 boiler, 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)
One must always guarantee a natural force draught in the flue between 6 and 8 Pa, to avoid that, if the
electric power should go out unexpectedly or adverse environmental conditions should arise, the room may be
filled with smoke or electric components overheat.
SPECIAL WARNING
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.
In case of no switch-on, clean the crucible before restarting the boiler.
Check that the aeration of the machine installation is always correct
(UNI10683 and UNI7129 Standard)

2. PRODUCT DESCRIPTION
This model of boiler is equipped with an innovative and patented biomass burner that is capable of burning
not only wood pellets, but also biomass (maze, grape seed, 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 boiler 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 box controls continually check
temperature sensors, electric motors, and safety devices, in case of anomalies, it will stop functioning and
signal it on the display (see alarm code paragraph). Room heating is guaranteed by a circulator mounted inside
the boiler that will start once the temperature reaches 55°C. Below this temperature the boiler activates the
anti-condensing function, therefore stopping the circulator.
Production of domestic hot water is guaranteed by a motorised deflector valve, also fitted inside the boiler, and
managed by the boiler probe that signals the position and ensures the hot domestic water boiler has priority.
3. PELLET QUALITY
There are various types and qualities of pellets on the market and it is important that the ones you use are not
of abysmal quality. A poor, cheap quality pellet could contain glues, resins or chemical substances that could
seriously jeopardise the functioning and the safety of the product, by inciting blockage of ashes and smoke
discharger, forming corrosive gas, reducing machine performance, release polluting substances into the
atmosphere and window incrustation. 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 DIN51731 standards or M7135 standards
including any updates.
The characteristics of wood pellet that should be used are: of a 6÷8 mm diameter, approx. 5÷20 mm length,
have an 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
the is non responsible if the boiler malfunctions as a result.
Store pellets at least 1 metre away from the boiler in a dry and sheltered part of the home.
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

6. HYDRAULIC CONNECTION
In order for the boiler to work correctly it must be suitably connected to a heating system. It is reminded that
installation must be carried out by trained personnel or companies according to MD 37/90. The
manufacturer declines any responsibility for installations not carried out correctly or by unqualified
personnel. For installation please refer to UNI7129 and UNI10412 (and any relative updates) Standards.
For a correct installation, verify that the hydraulic system is not leaking, thus jeopardising the functioning of the
generator and its integrity. In this regard, the installing company must adopt the solutions it considers
necessary in order to avoid that the thermal exchange surfaces of the boiler can, in time, suffer
limestone type incrustation, sludge, iron residues from the system and anything else foreign to the
heating water. This will enable optimising the thermal yield and functioning safety of the generator and
of the system. We strongly recommend installing a softener on the cold water inlet for system load and a mesh
filter on the boiler piping to the filter larger impurities.
COMPLETELY BLEED THE HEATING SYSTEM AND THE BOILER AT EVERY FILLING.
CONNECT THE SAFETY VALVE DRAIN AND BRING IT OUTSIDE THE BOILER.
A DIRT SEPARATOR WITH MAGNET MUST BE INSTALLED ON THE RETURN CIRCUIT TO
PROTECT THE BOILER’S INTERNAL COMPONENTS, AS THE ELECTRONIC CIRCULATOR,
FROM IMPURITIES AND FERROUS PARTICLES.
ALTERNATIVELY, WE RECOMMEND YOU TO USE A HEAT EXCHANGER TO SEPARATE THE BOILER’S
WATER FROM THE CIRCUIT’S WATER.
INSTALL AN ANTI-CONDENSATION VALVE, WITH SETTING AT 55°C, AS CLOSE AS POSSIBLE
TO THE BOILER.
If the production of domestic hot water is envisioned, installer a domestic boiler holding at least 80
litres for good boiler functioning.
The boiler is provided with an 8 litres expansion tank that, should it also be insufficient for the system, another
of adequate measure must be installed. Below is the calculation to determine the necessary capacity of the
expansion tank:
Should the existing expansion tank be insufficient
provide an additional tank.

7. 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 boiler 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 between 6 and 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 advisable that the smoke conduct has a solid material and eventual condensation collecting box,
positioned under the smoke conduct intake, so that it is easily accessible and can be inspected from the
airtight door.

8. 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 with silicon washers and not be corrugated flexible type.
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 boiler to a flue, make sure, with a professional chimney sweep, that the flue is perfectly whole..
Oppositely it is absolutely obligatory to encase the existing flue with material which is suitable enough to ensure
correct functioning (see fig.7) The flue must not lean against the fan. It is necessary to assess the layout and
structure of the house once the flue has been installed via walls and the roof, to ensure that installation has
been done correctly and is in conformity with fire safety regulations. You should also check: the internal section
of the flue, that there are no obstructions or material used to build it, the height, the fittingness of the stack and
the possibility to realise vent holes.
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 boiler 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 boiler using a "T" pipe connection using a ø80 - ø100 pipe fitting. (see fig. 8)
FLUE DIAMETER OPINION
Tube length less than 5 m 80 mm Correct
Tube length more than 5 m 100 mm (min) Mandatory
For installations at an altitude of more than
1200 m a.s.l.
100 mm (min) Recommended
Note: for each 90°curve add 1 m and for each 45°a dd ½ m. The lengths indicated on the table are only relevant for the vertical portion.
Horizontal parts must not exceed 2 m in length.
It is PROHIBITED to install air locks or valves that could obstruct the passage of smoke.
It is obligatory to use a "T" connection tube (see fig.8) with an inspection plug, as a connection between the
boiler and the flue, which will allow both the collection of soot that is deposited inside the tubes and periodical
cleaning of the flue, without the need to dismantle. 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.
It is advisable connect to the boiler with a horizontal track that is not more than 1m long.
If proper tube lengths are obeyed, the flue should have a draught between 6 and 8 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.

ENGLISH
12
INSULATION AND DIAMETER OF HOLES IN WALLS OR ON THE ROOF
Once the position of the boiler is established and that you have checked that the place of installation is ideal, it
is then necessary to make the hole for passing tubes through the wall. 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.: if the floor can not support the weight of the boiler, position a sheet platform of the correct size with
insulation applied on the floor (rock wool) and with a nominal density greater than 80kg/mc.
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: Seeing that regulations regarding installation of pellet fuelled boilers are constantly being
updated, ask ones installer for eventual changes.
9. O IDISING AIR INTAKE
Oxidising air can be taken from the atmosphere as long as there is sufficient ventilation, otherwise it is
necessary to take it from the outside: in this manner it is possible to guarantee an optimal combustion without
having to open air intakes in the room. For both cases please refer to the installation regulations in vigour (UNI
10683 and UNI7129) to avoid health risks of those who in the room where the machine has been installed.
Do not use flexible tubes and place a grid over the entrance (external) of the tube in order to stop alien
elements entering the system which could jeopardise the correct functioning.

MINIMUM DISTANCES FOR THE POSITIONING OF THE AIR INTAKE
For correct and safe positioning of the air intake (see
fig.9) where the minimum distances for any opening are
indicated. It is important to consider possible wall outlets
from other machines or kitchen aspiration hoods.
10. ELECTRICAL CONNECTIONS
All machines are equipped with power cables, for which, in case of the need for replacing, an authorised
technician must be used.
Before connecting to the power supply, check that:
•the electric plant has been fitted with a 6A magnetothermal switch
•the characteristics of the plant are sufficient enough to satisfy what is indicated on the machine
characteristic plaque (electric power, nominal voltage etc...)
•that the plant has a sufficient earth connection according to nominal regulations in vigour (earth connection
is obligatory by law)
•the power cable should never. at any point, overheat 50°C above room temperature: If a direct connect ion is
desired, it is necessary to use an omnipolar switch, with a minimum opening between contacts of 3mm, 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 the above indicated anti-injury regulations are not
respected.

11. PRELIMINARY CONTROLS BEFORE THE FIRST START UP
N.B.: if the floor cannot support the weight of the boiler, position a correctly sized, at least 4mm thick,
sheet platform with insulation applied on the floor (rock wool) and with a nominal density greater than
80kg/mc.
MANDATORY GUIDE LINES FOR THE SAFETY OF PEOPLE; ANIMALS AND OBJECTS.
The following information is about a number of obligatory general regulations for a correct installation, and is
intended for the installer.
• It is recommended to place insulation between the floor and the touching points of the machine with a sheet
at least 2mm thick and a diameter at least 50mm greater than the area occupied by the machine, if the
boiler is installed on a wooden floor.
• The flue tubing must not have a diameter that is less than 80 mm.
• Leave a space of at least 50mm between the rear of the boiler and the rear wall, to ensure correct air intake
• Leave a space of at least 70cm around the sides of the boiler, to ensure easy maintenance.
•Should the machine be installed close to flammable or combustible walls, keep a safe distance of 30cm
from the rear and sides of the machine. 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.
•Check for a correct level of combustible load inside the crucible.
•Completely bleed the heating system before starting the boiler.
•Verify that the safety valve drain has been conveyed outside the boiler.
For the first few minutes that the machine operates (for the first time) it may be possible to smell
paint this is normal Aerate the room with the boiler operational.
MAKE A FLUE GAS OUTLET
Perform the following actions, as shown in the figures below:
- Connect an ash collector "T" tube to the exhaust motor (1)
- Install a 90 °bend (2) to obtain the flue outlet on the rear side

Using biomass fuels (maize, grape seed, other) it is important to mix them properly to ensure that the
boiler works correctly.
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 correctly mix fuels it is recommended to weight them on scales with a precision of at least 100 g, and mix
them together in a single external container, not inside of the boiler, because that would not create an
homogenous mixture.
The menu “LOAD” allows to vary the quantity of combustible to be loaded and it is subdivided
into 3 levels of increase (+) and 3 levels of decrease (-): each level consists of 0,2 seconds,
therefore a total of +/- 0,6 seconds. Any variation made remains in permanent memory and it is
simultaneously programmed on all 6 power levels of the stove.
Before selecting on the display the type of fuel to be used make sure that it is the same as what is
already in the stove tank.
