1 GENERAL STANDARDS
In general, refers to regulations concerning "heat generators fed with wood and other solid fuels", UNI
10683:2012.
1.1 Fireplace or Chimney flue
Each device must have a vertical duct, called a chimney flue, for outside release of combustion fumes
produced by a natural draft.
The chimney flue must meet the following requirements:
•It must not be connected to any other fireplace, stove, boiler, or hood of any kind (Fig. 1).
•It must be properly spaced from combustible or flammable materials through an air gap or suitable
insulating material.
•The internal section must be uniform, preferably circular: the square or rectangular sections must have
rounded corners with a radius of no less than 20 mm, maximum ratio between the sides of 1.5, walls as
smooth as possible and without restrictions, curves must be regular and seamless, deviations from the
axis no greater than 45° (Fig. 2).
•Each device must have its own chimney flue with a section equal to or greater than the diameter of the
fume exhaust pipe of the stove and a height no less than the one stated.
•Never use two stoves, a fireplace and a stove, a stove and a wood stove, etc. in the same room since the
draft of one could damage the draft of the other. In addition, collective ventilation ducts that can cause a
vacuum in the installation environment are not permitted, even if installed in adjacent rooms and
communicating with the installation room.
•Creating fixed or mobile apertures on the chimney flue to connect equipment other than auxiliary devices
is prohibited.
•Passing other air supply channels and piping for utilities through the chimney flue, however large, is
prohibited.
•The chimney flue should be equipped with a collection chamber for solid materials and any condensate,
located below the mouth of the flue, so as to be easily opened and inspected from an airtight door.
•Whenever using parallel output chimneys, it is advisable to raise a bracing element. (Fig.3)

6
1.2 Chimney pot
The top of the chimney flue must be equipped with a device, called a chimney pot, which facilitates
dispersion into the atmosphere of combustion products.
The chimney pot must meet the following requirements:
•Its internal section and shape must be equivalent to that of the chimney flue.
•Have a useful outlet section no less than double that of the chimney flue.
•Chimney pots that emerges from the roof or which remain in contact with the outside (for example in the
case of an open loft), must be covered with brick elements and well isolated. It must be constructed so as
to prevent penetration into the flue of rain, snow, or foreign bodies and so that, in the event of winds in any
direction and at any angle, it assures the discharge of combustion products (windproof chimney pot).
•The chimney pot must be positioned so as to guarantee an adequate dispersion and dilution of combustion
products and, in any case, outside the zone of reflux. This zone can be different sizes and shapes depending
on the angle of slope of the roof, so it is necessary to adopt the minimum heights shown in Fig.4 and Fig.5.
•The chimney pot must be of windproof and exceed the height of the ridge, Fig.4 and Fig.5.
•Any buildings or other obstacles that exceed the height of the chimney pot must not be close to the chimney
pot itself (Fig.4).

1.3 External air intake vent
•The stove must have the air necessary to ensure smooth combustion operation and good environmental
well-being.
•Make sure that the room where the stove is installed offers sufficient ventilation and install an air supply
duct from the outside with the recommended minimum section of 100 cm².
•The air intake vent must communicate directly with the installation room of the stove, positioned so as to
prevent it from being blocked and protected with a permanent non-lockable grid or other suitable protection
provided that it does not reduce the minimum section.
•Air flow can also be obtained from a room adjacent to the installation room, provided that this flow can be
carried out freely through permanent, non-closable openings communicating with the outside.
•With respect to the installation room, the adjacent room should not be put under vacuum with respect to
the external environment as a result of a reverse draft caused by the presence in this space of another
utility device or suction device. The room adjacent to the permanent openings must meet the requirements
set out in the paragraphs above. The adjacent room cannot be used as a garage, for storage of
combustible material or for activities involving a risk of fire.
1.4 Connection to the chimney flue
(see paragraph 4.5)
1.5 Preventing house fires
Installation and use of the stove must be in accordance with the manufacturer's instructions and with local
habitability regulations.
CAUTION: when a fume exhaust pipe passes through a wall or ceiling, particular installation methods must
be applied (protection, thermal insulation, distances from heat sensitive materials, etc.).
•The fireplace connecting tube must never pass through a combustible surface.
•Do not connect this unit to a chimney flue already being used by another device.
•It is also advisable to maintain all combustible elements or flammable material such as beams, wooden
furniture, curtains, flammable liquids, etc. outside the radiation area of the furnace and at a distance of at
least 1 m from the heating block. .
•In the event that the surrounding space has coverings in combustible or heat-sensitive material, a
protective membrane made of non-combustible insulating material must be interposed. If the flooring is
made of combustible material, a non-combustible protective material that protrudes laterally and frontally
from 15cm to 30 cm must be provided at the mouth of the furnace.
•For further information, refer to local requirements.

2 SPECIFICATIONS AND TECHNICAL DATA
2.1 Specifications
Stoves and pellet stoves are devices built to work with good quality wood pellets only (see par. 3 fuel).
Hydro models must be connected to the plumbing system.
2.2 Technical data (see attached sheet)
2.3 Rear connection dimensions (see attached sheet)
2.4 Product identification data (see attached sheet)
The technical label shows device data and performance. Tampering with, removing or lack of a technical
label makes installation and maintenance operations difficult, due to the lack of product identification. In the
event of damage, request a duplicate from our service centre. Given the importance of the data label, we
recommend installing the stove at a distance at which it is always visible.
2.5 Electrical diagrams

3 FUEL
3.1 General notes
The pellet stove is designed to burn wood pellets only.
Wood pellets are a fuel obtained from the pressing of sawdust timber, extracted from the processing and
transformation residues of dried wood material. The compactness of the product over time is guaranteed by
a natural origin substance contained in the wood: lignin. The typical small cylinder form is obtained by
extrusion.
Various types of pellets with quality and characteristics that vary depending on the processing and type of
wood species used are available on the market.
CAUTION: Always use certified quality wood pellets: i.e. DIN, DIN PLUS, ÖM 7135, Pellet Gold, Catas
etc. The company does not guarantee proper stove functioning with the use of low-quality pellets.
Stoves and heating stoves are tested and programmed to ensure good performance and perfect quality
operation with specific characteristic pellets:
components: wood
length: < 30 mm
diameter: 6-6.5 mm
lower calorific value: 4.8 kWh/kg
humidity rate: < 8 %
residual ash: < 0.5 %
GOOD QUALITY pellets are smooth, shiny, slightly dusty and with regular length.
LOW QUALITY pellets are of varied lengths, dusty with vertical and horizontal splits.
Since pellet characteristics and quality greatly influence the autonomy, efficiency and proper
operation of the stove, we recommend:
AVOID using pellets with dimensions different from that described by the manufacturer.
AVOID using low quality pellets or pellets containing dispersed sawdust powder, resins or chemicals,
additives or adhesives.
AVOID using moist pellets.
The use of unsuitable pellets causes:
•clogging of the brazier and fume discharge ducts
•increased consumption of fuel
•decreased efficiency
•no guarantee of normal stove operation
•dirtying of glass
•production of unburned granules and heavy ash
The presence of moisture in pellets increases the volume of the capsules and crumbles, causing
•feeding system malfunctions
•poor combustion
Pellets should be stored in a dry and sheltered place. Particular attention should be given to the handling of
the bags to prevent their crushing, resulting in the formation of sawdust.
Stove operation parameters may have to be altered when using quality pellets with dimensional and calorific
characteristics different from those indicated. Contact an authorised service centre if necessary.
THE USE OF POOR QUALITY PELLETS NOT IN ACCORDANCE WITH MANUFACTURER'S
INSTRUCTIONS NOT ONLY DAMAGE THE STOVE AND COMPROMISE PERFORMANCE BUT MAY
RESULT IN FORFEITURE OF THE WARRANTY AND COMPANY LIABILITY.

4 INSTALLATION
4.1 General notes
The heating system or appliance must be installed in order not to damage the building and other systems.
The installer must strictly comply with standard UNI 10683:2012.
4.1.1 Installation in the presence of several appliances.
The presence of several appliances powered with different fuels, as well as hoods with or without extractor,
must be evaluated during preventive checks and during the start-up test in order to detect any variation
compared to the design conditions or any aspect that cannot be detected during the design phase. The room
must be well-ventilated according to the instructions of every single device. The external air intake vent must
meet the requirements of paragraphs 1.3 and 4.4
4.1.2 Suitability of the installation rooms
•Installing the device inside rooms at risk of fire is prohibited.
•Outdoor installation in locations exported to weathering or humid areas is prohibited.
•Boilers must be installed in a technical room. It is forbidden to install them in open verandas or
outdoors.
•Installation in rooms containing other generators that collect air from the environment is prohibited (par 6.4
UNI 10683:2012).
•Sealed or closed operation appliances with external ducted combustion air intake can be installed only in
bathrooms, bedrooms, and studios.
•The minimum volume of the installation room must be greater than 15 m³.
•Boiler installation must be carried out in a location which allows safe and easy use and simple
maintenance. Said location must also be equipped with electrical grounding as required bylaw.
4.1.3 Fume discharge system
Every device must be connected to a fume discharge system, which ensures dispersion of combustion
products into the atmosphere.
The combustion products must be discharged from the roofs. Direct wall discharge or towards closed spaces,
even in open air, is prohibited.
The components must be made of material with A1 fire reaction class. In particular, the use of metal extendible
and flexible hoses is prohibited.
CAUTION: ensure that the plug for electrical connection remains accessible after boiler installation.

4.3 Flooring protection
In the event of valuable flooring or flooring that is sensitive to heat, moisture or is flammable, a floor protection must be
used (i.e. sheet steel, marble or tile slabs).
Whichever type of protection selected, it must protrude at least 300 mm from the front, at least 150 mm from the sides
of the stove, must withstand the weight of the stove and have a thickness of at least 2 mm (Fig. 6 and 7).
Fig. 6 Fig. 7
4.4 Minimum distances for positioning air intake vents
Pellet stove combustion air intake vents cannot be connected to an air distribution system or directly
to a wall-mounted air intake vent.
Correct and safe positioning of the air intake vent must comply with the measures and requirements described
in paragraph 1.3.
There are distances to be respected in order to avoid that combustion air be removed by another source; for
example, a window opening can suck the air outside, making it miss the stove.
The air intake vent must be located at least:
1.5 m

4.5 Fume exhaust duct
4.5.1 General notes
CAUTION: the pellet stove is not like other stoves. Fume draft is forced thanks to a fan that maintains
the pressure in the combustion chamber and slight pressure around the exhaust duct. Therefore, you
must verify that the latter is completely watertight and properly installed, both from the point of view
of function and safety.
Construction of the exhaust duct must be done by specialised personnel or companies, as reported in the
following manual. Always create the exhaust system so that periodic cleaning is assured without having to
dismantle any parts.
Tubes must ALWAYS be sealed with silicone (no cementing) that maintains resistance and elasticity
characteristics at high temperature (250°C) and are to be secured with a Ø3.9mm self-tapping screw.
•The installation of dampers or valves which may obstruct the passage of exhaust fumes is prohibited.
•Installation in a chimney flue where exhausted fumes or vapours from other equipment (boilers, hoods,
etc.) is prohibited.
4.5.2 Tubes and maximum usable lengths
Painted aluminised steel tubes (minimum thickness 1.5 mm), stainless steel tubes (Aisi 316) or porcelain
tubes (minimum thickness 0.5 mm) with a nominal diameter of 80 mm or 100 mm (for tubes inside the
chimney flue max 150 mm) can be used.
Flexible hoses are permitted if they fall within the limits prescribed by law (in stainless steel with smooth inner
wall). The male-female connection collars must be at least 50 mm long.
Tube diameter depends on the type of system. The stove has been designed for Ø 80 mm and Ø 100 mm
tubes (check the technical data sheet of the selected model). As can be seen in the table below, a double-
wall Ø 100 mm tube may be necessary in some cases and models.

4.5.3 Holes for exhaust tube passage on walls or roof: recommended insulation and
diameter
Once the location of the stove has been decided (section 4.1), you will have to drill the hole for passage of
the fume exhaust tube. This varies depending on the type of installation (therefore on the exhaust tube
diameter, see 4.5.2) and on the type of wall or roof to be crossed (table 3).
The insulator must be of mineral origin (rock wool, ceramic fibre) with a nominal density greater than 80
kg/m3.

4.5.4 Using a traditional type chimney flue
If you wish to use an already existing chimney flue, it is advisable to have it checked by a professional chimney
sweep to ensure that it is watertight. This is because fumes, being slightly pressurised, could infiltrate cracks
in the chimney B y flue and invade living spaces. If an inspection finds that the chimney flue is not perfectly
intact, it is advisable to intubate it with new material. If the existing chimney is large, we recommend inserting
a tube with a maximum diameter of 150 mm. It is also advisable to insulate the fume exhaust duct. Figs. 11
and 12 demonstrate the solutions to adopt if you want to use an existing chimney flue.
Fig. 11 Fig. 12

16
4.6 Using an external fume duct
An external fume duct can be used only if it meets the following requirements:
•Only insulated tubes (double wall) in stainless steel, secured to the building (Fig.13) should be used.
•An inspection area should be created at the base of the duct for performing periodic checks and
maintenance.
•It should be equipped with a windproof chimney pot and observe the distance "d" from the ridge of the
building as described in par. 1.2.
•Fig. 13 shows the solution to be utilised when using external fume ducts.

5 ASSEMBLY
5.1 General notes
Here are some general recommendations to follow in order to prevent accidents or damage to the product:
•Unpacking and installation must be performed by at least two people.
•All handling operations must be carried out using appropriate means and in full compliance with
safety regulations.
•The positioning of the packed product must be maintained in accordance with the guidelines supplied by
pictograms and written on the packaging.
•If using ropes, straps, chains, etc., make sure they are suitable for the weight to be unloaded and are in
good condition.
•When moving the package, move with slow and continuous movements to avoid tearing the ropes, chains,
etc.
•Do not tilt excessively in order to avoid overturning.
•Do not stand within range of the loading/unloading means (forklifts, cranes, etc.).
5.2 Unpacking
Unpack the product being careful not to damage or scratch it. Remove the accessory package and any pieces
of polystyrene or cardboard used to block removable parts, etc. from the stove furnace.
Also remember not to leave packaging components (plastic bags, polystyrene, etc.) within the reach of
children, as they could be potential sources of danger. Dispose of them according to regulations.
5.3 Electrical connection
The stove is supplied with a power cable that must be plugged into a 230V 50Hz outlet.
Outlet connection in the rear of the stove is illustrated in Fig. 14.
Absorbed power is indicated in the "SPECIFICATIONS AND TECHNICAL DATA" chapter of this manual.
By law, the system must be properly grounded and with a differential circuit-breaker. Make sure that the
electrical power cable does not come into contact with hot parts when set in its final position.
Fig. 14
CAUTION: ensure that the plug for electrical connection remains accessible after stove installation.

18
5.4 Water connection
Connection of the stove to the hydraulic system must be exclusively performed by qualified
personnel, who is able to perfectly perform the installation, complying with the regulations in force
in the Country of installation.
If the installation of the stove requires interaction with another pre-existing system equipped with another
heating device (gas boiler, methane boiler, gasoline boiler, etc.), contacting qualified personnel able to
respond to the conformity of the system, according to the requirements of the law in force regarding the
subject, is more recommended.
The company denies any liability in case of damages to property or persons or in case of no or
incorrect operation if the aforementioned warnings are not complied with.
Caution: To connect the delivery pipe, return pipe, refilling pipe and drains arrange flexible hoses at least 70
cm long and shut-off shutters in order to isolate the machine from the water system should moving it to perform
routine/special maintenance be required.
Connect the thermal safety drain of the machine to an appropriate drain funnel with no shut-off valves.
In case of thermal safety drain valve operation, the water must be free to flow without causing damage to
persons and built-up area.
When the instrument is fully operational it produces hot water at a temperature necessarily lower than the
boiling one and therefore the thermal system must be designed in compatibility with the machine
specifications.
During installation and operation take into account that disposal of the minimum power delivered by the
machine must be ensured.
Make sure that the thermal hydraulic system is fitted with an additional and adequate closed
appropriately dimensioned expansion vessel.
For the installation of an additional expansion vessel take into account that usually 1 litre of vase compensated
10 litres of system and at least 1 litre is always dedicated to the water inside the boiler. The expansion vessel
inserted inside the device is pre-charge at the pressure indicated in the plate, adjust the pre-charged pressure
of the expansion vessels to the operating pressure of the thermal system.
We recommend installing a 1” anti-condensation valve with 55 °C opening and softener systems.
It is best to keep in mind that deposit drastically lower performance due to their extremely low thermal
conductivity.
5.4.1 System filling
Before performing the boiler connections thoroughly wash the thermal system (pipes, heating bodies,
etc.) with appropriate paint or deposit removers able to remove any residues which may compromise the
correct operation of the boiler.
Hydraulic connections must be performed rationally using the connections of the boiler. The boiler safety
valve drain must be connected to a drain funnel. Otherwise, if the drain valve operates flooding the room, the
boiler manufacturer shall not be deemed responsible.
We recommend filling the system at a pressure of 1.0 - 1.2 bar (pressure is shown with the b symbol on the
boiler display) the boiler can still function from 0.6 bar to 2.5 bar.
In case of installation in spaces where temperature may drop below 0°C, inserting appropriate antifreeze in
the system is required since the boiler does not have an automatic antifreeze system.
Thermostoves with domestic hot water production
If the water hardness of your home is high, we recommend installing a softening system and a filter
upstream.
We recommend having the exchanger undergo yearly maintenance to remove limestone sediments and
mineral salts.

5.5.1 Indicative hydraulic diagram heating only
Caution: to prevent the heating system from having to be regularly cleaned it is best to install a magnetic
sludge remover, this filter aids routine maintenance, increases boiler life span, aid removal of impurities and
increased global efficiency of the system.
The magnetic sludge remover filters the heating system removing sludge, ferrous or sandy residues which
circulate in the pipes, if not removed they create surfaces which do not permit heat transmission, consequent
pellet consumption and possible boiler malfunction.
5.6 External thermostat installation
Stove operation can be adjusted to any external room thermostat connected to the circuit board (see electrical
diagram). The thermostat connection is made using a 2x0.5 mm2 cable.
This operation should be performed by qualified personnel.
If you choose to use an external thermostat, set the room temperature value on the stove display to the
minimum (7°C).
At this point, the stove will be controlled by an external thermostat.
During the work phase, the external thermostat is closed. The stove works at the set power level. A virtual
LED will activate on the upper left of the display. If the thermostat opens, the stove goes to minimum power
level and the display shows the message "modulating". This modulation stops only if the thermostat goes
back to being closed. In this case, the stove will return to the power set by the user, the display will show the
message "modulating" and an indication of the set power level will return.
