WARNINGS
This instructions manual is an integral part of the product: make sure that it always accompanies the appliance, even if
transferred to another owner or user, or if transferred to another place. If it is damaged or lost, request another copy from the
area technician. This product is intended for the use for which it has been expressly designed. The manufacturer is exempt from
any liability, contractual and extracontractual, for injury/damage caused to persons/animals and objects, due to installation,
adjustment and maintenance errors and improper use.
Installation must be performed by qualied sta, which assumes complete responsibility for the denitive installation
and consequent good functioning of the product installed. One must also bear in mind all laws and national, regional,
provincial and town council Standards present in the country in which the appliance has been installed, as well as the
instructions contained in this manual.
The Manufacturer cannot be held responsible for the failure to comply with such precautions.
After removing the packaging, ensure that the content is intact and complete. Otherwise, contact the dealer where the appliance
was purchased.
All electric components that make up the product must be replaced with original spare parts exclusively by an authorised after-
sales centre, thus guaranteeing correct functioning.
SAFETY
The generator must not be used by persons (including children) with reduced physical, sensory and mental capacities or
who are unskilled persons, unless they are supervised and trained regarding use of the appliance by a person responsible for
their safety.
Children must be checked to ensure that they do not play with the appliance.
Do not touch the generator when you are barefoot or when parts of the body are wet or damp.
The safety and adjustment devices must not be modied without the authorisation or indications of the manufacturer.
Do not pull, disconnect, twist electric cables leaving the stove, even if disconnected from the electric power supply mains.
It is advised to position the power supply cable so that it does not come into contact with hot parts of the appliance.
The power supply plug must be accessible after installation.
Do not close or reduce the dimensions of the airing vents in the place of installation. The airing vents are essential for
correct combustion.
Do not leave the packaging elements within reach of children or unassisted disabled persons.
The hearth door must always be closed during normal functioning of the product.
When the appliance is functioning and hot to the touch, especially all external surfaces, attention must be paid
Check for the presence of any obstructions before switching the appliance on following a prolonged period of inactivity.
The generator has been designed to function in any climatic condition (even critical). In particularly adverse conditions
(strong wind, freezing) safety systems may intervene that switch the generator o. If this occurs, contact the technical after-
sales service and always disable the safety systems.
In the event the ue catches re, use suitable systems for suocating the ames or request help from the re brigade.
This appliance must not be used to burn waste
Do not use any ammable liquids for ignition
During the lling phase do not put the bag of pellets to into contact with the product
The majolicas are top quality artisan products and as such can have micro-dots, crackles and chromatic imperfections.
These features highlight their valuable nature. Due to their dierent dilation coecient, they produce crackling, which
demonstrate their eective authenticity. To clean the majolicas, it is recommended to use a soft, dry cloth. If a detergent or
liquid is used, the latter could penetrate inside the crackles, highlighting them.
ROUTINE MAINTENANCE
Based on Decree 22 January 2008 n°37 art.2, routine maintenance means interventions aimed at reducing degradation due to
normal use, as well as dealing with accidental events entailing the need of rst interventions, which however do not modify
the structure of the system upon which one is intervening or its intended use according to the requirements laid down by the
technical standards in force and by the manufacturer's use and maintenance manual.

HYDRAULIC SYSTEM
Certain concepts referring to the Italian UNI 10412-2 (2009) Standard are described in this chapter.
As previously described, when installing, all national, regional, provincial and town council Standards in force provided by the
country in which the appliance has been installed must be complied with.
During installation of the stove it is MANDATORY to adjust the system with a manometer in order to display the water pressure.
INSTALLATION AND SAFETY DEVICES
The installation, relative system connections, commissioning and inspection of correct functioning must be carried out perfectly,
in total compliance with Standards in force, both national, regional and municipal, as well as these instructions.
For Italy, installation must be carried out by professionally authorised sta (Ministerial Decree dated 22.01.08 n°37).
The manufacturer declines all responsibility for damages to objects and/or persons caused by the system.
TYPE OF SYSTEM
There are two dierent types of system:
Open vessel plant and closed vessel plant.
The product has been designed and realised to work with closed vessel systems.

SAFETY DEVICES FOR CLOSED VESSEL SYSTEM
According to the UNI 10412-2 (2009) Standard in force in Italy, the closed systems must have: safety valve, pump control
thermostat, acoustic alarm activation thermostat, temperature indicator, pressure indicator, acoustic alarm, regulation automatic
circuit breaker switch, automatic circuit breaker block switch (block thermostat), circulation system, expansion system, safety
dissipation system incorporated with the generator with thermal safety valve (self-activated), whenever the appliance does not
have a temperature self-adjustment system.
DISTANCES OF SAFETY DEVICES ACCORDING TO THE STANDARD
The temperature safety sensors must be in place 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 1m from the machine.
COMMISSIONING CHECKS
Before connecting the boiler:
a) wash all system piping in order to remove any residues which might compromise the correct functioning of certain system
components (pumps, valves, etc.).
b) check to verify 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 control can the ue tting be mounted between the boiler and
the ue. A check of the connections with pre-existing ues is recommended.
AUTOMATIC THERMOSTATIC MIXER VALVE (MANDATORY)
It is required to create an adequate anti-condensation circuit that ensures a return temperature for the appliance of at least 55°
C. The anti-condensation valve, for example, is applied in solid fuel boilers as it prevents the return of cold water in the heat
exchanger.
Routes 1 and 3 are always open and, together with the pump installed on the return, they guarantee water circulation inside
the biomass boiler exchanger.
A high return temperature allows eciency improvement, reduces formation of smoke condensation and prolongs the life
span of the generator.
Valves on the market have dierent calibrations. The manufacturer advises use of model 55°c with 1" hydraulic connections.
Once the valve calibration temperature is reached, route 2 is opened and the boiler water goes to the system via the ow.
Valve sold as an accessory (optional)

bathroom, bedroom or common room of the building.
FUMES EXHAUST SYSTEM
GENERAL REQUIREMENTS
The heat generator works in a vacuum and has an output fan for fume extraction. Each appliance must be connected to a suitable
fumes exhaust system and ensure adequate dispersion of the combustion products into the atmosphere.The combustion products
must discharged above the roof. Direct discharge from the wall or towards closed spaces is forbidden, even with clear skies.
In particular, it is forbidden to use exible and extendible metal pipes.
The chimney should only receive the exhaust of the smoke duct connected to the appliance; collective ues or conveying
exhausts from hoods above cooking appliances of any kind, or exhausts from other generators into the chimney itself or smoke
duct are not allowed.
The smoke duct and the chimney must be connected with a continuity solution, in order to prevent the chimney from resting
on the appliance.
It is forbidden to have other air supply channels and pipes for plant engineering transit inside the fumes exhaust systems,
especially if over-sized.
The components of the fumes exhaust system must be chosen in relation to the type
of appliance to be installed in compliance with:
in the event of metal chimneys, UNI/ TS 11278, with particular attention to what is stated in the specication;
in the event of non-metallic chimneys: UNI EN 13063-1 and UNI EN 13063-2, UNI EN 1457, .-UNI EN 1806; considering especially:
temperature class;

CHIMNEY
In addition to the general requirements, the chimneys for releasing combustion products into the atmosphere must:
operate under negative pressure (operation under positive pressure is not allowed);
have a preferably circular internal section; square or rectangular sections must have rounded corners with a radius of no
less than 20 mm (hydraulically equivalent sections may be used, as long as the ratio between the longer side and the shorter
side of the rectangle, which circumscribes the section, is in any case no greater than 1.5);
be designed for fumes be designed for fumes expulsion;
be predominantly vertical and have no narrowing along their entire length;
have no more than two direction changes with a slope angle no greater than 45°;
be tted with, in the event of operating in damp conditions, a device for reux drainage (condensation, rainwater);
Ducted system
A ducted system can be installed with one or more ducts, operating only with negative pressure with respect to the environment.
The exible hose compliant with UNI EN 1856-2, with T400-G characteristics, meets the requirements.
CHIMNEY CAPS
The chimney caps must meet the following requirements:
they must have a useful outlet section no less than double of that of the chimney/ducted system on which it is installed;
they must be adapted in order to prevent the penetration of rain and snow in the chimney/ducted system;
they must be built so that, in the event of winds coming from all directions and from any angle, the expulsion of combustion
products is in any case ensured;
they must be free from mechanical intake aids.

The outlet of a chimney/ducted system must not be near obstacles that may create turbulence areas and/or prevent proper
expulsion of combustion products and maintenance operations to be carried out on the roof.
Verify the presence of other chimney caps or skylights and dormers.
FUMES EXHAUST SYSTEM PRODUCT REQUIREMENTS
Temperature class
In the event of a pellet appliance, temperature classes below T200 are not allowed.
Soot re resistance class
The fumes exhaust system interlocked with appliances supplied by solid fuels require soot re resistance, and the specication
must be indicated by the letter G followed by the distance from combustible materials in millimeters (XX) (in compliance with
UNI EN 1443) .
In the event of pellet appliances, the fumes exhaust systems must be airtight; if double designation elements are used (G and
O, with or without seal elastomer) for connecting the appliance to the chimney, one must comply with the minimum distance
XX in millimeters, indicated for designation G; in the event of re due to soot, one must ensure the restoration of the initial
conditions (by replacing the gaskets and damaged items and cleaning those remaining in use).
Ignition tests
Operation of the appliance must be veried with an ignition test, i.e.:
for mechanical feed appliances, one must complete the ignition test, verify proper operation for at least the next 15
minutes and adjust the switch-o;
For appliances installed in a hot water heating system (closed replaces, thermo-stoves), testing must also extend to the entire
hydraulic circuit.
COMBUSTION PRODUCTS OUTLET QUOTA
The outlet quota is determined by measuring the minimum height between the roof covering and the lower point of the fumes
expulsion section into the atmosphere; this quota must be outside the reux area and at an adequate distance from obstacles
which hinder or make the expulsion of the combustion products dicult or from openings or accessible areas.
Reux area
The outlet quota must be outside the reux area calculated according to the indications below.
Near the ridge one considers the lowest between the two.

Coverings and nishings
The coverings and nishings must only be applied after having veried the proper operation of the appliance according to the
indicated modalities
TECHNICAL INSTALLATION DOCUMENTATION
When installation is complete, 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.
Installation performed by several parties
If the individual installation steps are carried out by dierent parties, each must document the work carried out for the customer
and the for the operator working on the next step.
INSPECTION AND MAINTENANCE
Frequency of operations
Maintenance of the heating system and of the appliance must be carried out on a regular basis according to the table below:
TYPE OF APPLIANCE INSTALLED <15kW (15- 35) kW
Pellet operated appliance 1 year 1 year

PELLETS AND FEEDING
Pellets are made by applying high pressure to sawdust, or wood waste products (not containing paint) from sawmills, carpentry
and other activities related to processing and working with wood. Given that it does not use any glue to hold it together this
type of fuel is completely environmentally friendly. In fact the compactness of the pellets over time is guaranteed by a natural
substance found in the wood itself: wood coal. In addition to being an environmentally friendly fuel in that it pushes wood
residues to the limits pellets also have technical advantages. While wood has a caloric value of 4.4kWh/kg. (with 15% humidity
after around 18 months of seasoning) the caloric value of pellets is 5 kWh/kg. Pellet density is 650kg/m3 and the water content
is equal to 8% of its weight. For this reason they do not require seasoning in order to arrive at a suciently adequate degree of
heat yield.
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
The pellets used must comply with the characteristics described
by the following standards:
EN PLUS - UNI EN 14961 - 2 (UNI EN ISO 17225-2) class
A1 or A2
The manufacturer always recommended using pellets with a
diameter of 6 mm with its products.
PELLET STORAGE
In order to ensure problem-free combustion pellets must be
stored in a dry place.
Open the tank lid and load the pellets using a scoop.
CHECKS AND PRECAUTIONS FOR FIRST IGNITION
IMPORTANT!
IN ORDER FOR THE GENERATOR TO WORK PROPERLY, THE HYDRAULIC SYSTEM’S PRESSURE MUST BE BETWEEN
0.6 AND 2.5 BAR.
If the pressure detected by the digital pressure switch is below 0.6 or above 2.5 bar, it triggers a boiler alarm.
Bringing the water pressure within the standard values, it is possible to reset the alarm by pressing the button /1 for 3 seconds
(The alarm can be reset only if the fumes motor has stopped and 15 minutes have elapsed from the display of the alarm)
THE PELLET LOADING MOTOR DOES NOT WORK:
Due to the lling of the system, it is normal that there is air inside the circuit.
During the 1st ignition cycle, water movement causes the displacement of air bubbles and their out-ow from the automatic
vents out of the system. This can cause the pressure to drop and activate the minimum pressure switch, which stops the motor
that transports the pellets and, therefore, the heat generator.
Vent out the system, if necessary even multiple times, to remove the air, and reload it if the pressure is too low.
It is not a malfunction, but a normal occurrence due to its lling. After lling, the plumber must always thoroughly vent the
system, using the special vents in the circuit and running the "air breather" function on the machine. (After the rst ignition and
with a cold machine, re-activate the function "air breather" - see chapter "OTHER FUNCTIONS”)
BULB THERMOSTATS - RESET:
Check by pressing the reset buttons (85 - 100°C) located on the back of the appliance, before contacting a technician (see
section RESET).
