PRODUCT PERFORMANCE CHECKS.
All our products undergo ITT TESTS carried out by a notied third party laboratory (system 3) and in accordance with Regulation (EU)
number 305/2011“Construction products”, according to standard EN 14785:2006 for household appliances and“Machinery Directive”EN
303-5 for boilers.
In the case of tests for any market surveillance or inspections by third parties, please consider the following warnings:
• To reach the declared performance levels, the product must perform an operating cycle of at least 15-20 hours beforehand.
• Set the average draught of the combustion fumes as specied in the“technical product features”table
• Thetypeofpelletsusedmustcomplywiththe currentEN ISO17225-2class A1 regulation.Fir pellets areusually used for certication.
• The amount of thermal energy can vary according to the length and caloric value of the fuel. This may require some adjustments
(accessed from the user menu) to comply with the hourly consumption specied in the“technical product features”table. Using class
A1 pellets guarantees a caloric value that is likely to be close to that used in the product certication; the size of the pellet grains can
signicantly aect hourly fuel loading and consequently performance; it is therefore suggested to use pellets with a 6 mm diameter
and an average length of around 24 mm (avoid pellets that are too long or excessively crushed).
• Withwood-burningappliances,the fuel mustcomply with thecurrentENISO 17225-5 class A1regulation.Check the correctmoisture
of the fuel, as it must be within the range of 12 - 20% (it is best if the moisture is close to 12%, as is normally used in certication). As
the fuel moisture increases, dierent combustion air settings are required, which are implemented from the combustion air register,
thereby modifying the mixture of primary and secondary air
• It is important to check the operation of devices that can aect performance (for example air fans or electric safety devices) in case
of damage due to handling.
• Nominal performance has been obtained by setting the maximum ame power and room ventilation in manual mode.
Performance at reduced power was achieved at minimum ame and ventilation power (P1 andV1) in manual mode.
The other conditions correspond to intermediate ventilation and power.
• If a “verication”mode is provided in the menu, set this function during the readings to ensure that no temperature modulation
occurs due to an incorrect setting of the operating parameters.
• Lastly, strictly comply with the sampling points specied in the regulations in terms of emissions as well as temperature

Technical Dept. - All rights reserved - Reproduction prohibited
The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case,
always observe the regulations in force in the country of installation.
PELLETS
The pellet is obtained from natural dried wood sawdust (without paint). The compactness of the material is guaranteed by the lignin
contained in the wood itself, without glue or binders.
The market oers dierent types of pellets with characteristics that vary according to the wood mixtures.The most common diameter on
the market is 6 mm (although 8 mm diameter is also available) with a length, on average, between 3 and 40 mm. A good quality pellet
has a density of between 600 and 750 or more kg/cubic metres and a moisture content that accounts for 5 to 8% of its weight.
Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner
combustion than that of fossil fuels.
While good-quality wood has a caloric value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), that of pellets is around
4.9 kW/kg.To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually supplied in 15
kg bags, therefore, storing them is very convenient.
Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.
The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber need to
be cleaned.
The main quality certications for pellets currently available on the European market guarantee that the fuel complies with class A1/
A2 according to ISO 17225-2. These certications include, for example, ENPlus, DINplus, Ö-Norm M7135, and specically assure that the
following characteristics are complied with:
• caloric value: 4.6 - 5.3 kWh/kg.
• Water content: ≤ 10% of the weight.
• Percentage of ash: max 1.2% of the weight (A1 less than 0.7%).
• Diameter: 6±1/8±1 mm.
• Length: 3-40 mm.
• Content: 100% untreated wood without the addition of binding agents.
The company recommends using certied fuel for its products (ENPlus A1, DINplus, Ö-Norm M7135).
The use of pellets that do not comply with the characteristics specied previously may compromise the operation of
your product and therefore invalidate the warranty and product liability.

FOREWORD
The heating system (generator + combustion air supply + combustion product expulsion system + any hydraulic/aeraulic
system) must be installed in compliance with the laws and regulations in force1, and carried out by a qualied technician,
who must issue a declaration of conformity of the system to the system manager and shall undertake full responsibility
for nal installation and consequent good operation of the product.
The manufacturer declines all responsibility in the event of installations that do not comply with the laws and regulations in force and
inappropriate use of the appliance.
In particular one must ensure that:
• the environment is suitable for installing the appliance (oor load-bearing capacity, presence or possibility of creating an adequate
electrical/hydrauic/aeraulic system when required, volume compatible with the appliance characteristics, etc.);
• the appliance is connected to a smoke expulsion system correctly sized according to EN 13384-1, which is resistant to soot re and
which complies with the distances prescribed by the combustible materials indicated on the plate data;
• there is a suitable combustion air ow to the appliance;
• other combustion appliances or extraction devices installed do not cause a negative pressure of more than 4 Pa in the room where
the product is installed compared to the outside (only sealed appliances are allowed a maximum of 15 Pa of negative pressure in
the room).
1The national reference standard for the installation of domestic appliances is UNI 10683 (IT) - DTU NF 24.1 (FR) - DIN 18896 (DE) - NBN B 61-002 (BE) - Real Decreto 1027/2007
(ES)
In particular, it is recommended to strictly observe the safety distances from combustible materials to avoid serious harm
to people and to the integrity of the home.
Installation of the appliance must ensure easy access to service the appliance itself, the smoke channels and the ue.
Always maintain adequate distance and protection in order to prevent the product from coming into contact with water.
It is forbidden to install the stove in rooms with a re hazard.
With the exception of sealed installations, it is also forbidden for liquid fuel appliances with continuous or intermittent
operation that draw the combustion air from the room they are installed in or B-type gas heating appliances, with or
without the production of domestic hot water, to coexist in the same room or in interconnecting rooms.
Sealed installation means that the product is certied as sealed and its installation (ducting of the combustion air
and connection to the chimney) is airtight with respect to the installation environment.
A sealed installation does not consume the room’s oxygen but draws all the air from the outer environment (if suitably ducted) and makes
it possible to install the product, therefore, it can be installed in all houses that require a high degree of insulation such as“passive”or
“high energy eciency”houses. Thanks to this technology there is no risk of smoke emissions in the room, hence no air inlets and relevant
ventilation grilles are required in the installation premises.
Consequently, there will be no more draughts of cold air in the room, which would otherwise make it less comfortable and reduce the
overall eciency of the system. The sealed stove may even be installed in a sealed installation that is compatible with the presence of
forced ventilation or in premises that might have negative pressure with respect to the outside.

If the oor is made of combustible material, use a protection made of non-combustible material (steel, glass...) that also protects the front
from any falling combusted material during cleaning operations.
Always t a oor guard if the oor is made of ammable material.
Install the stove also detached from any non-combustible walls/surfaces, observing a minimum clearance of 200 mm (back) and 300 mm
(side) to allow eective aeration of the appliance and a good distribution of heat in the room.

14
2-INSTALLATION
In any case, ensure adequate distance to facilitate access during cleaning and extraordinary maintenance. If this is not possible, it must
still be possible to distance the product from adjacent walls/elements.
This operation must be performed by a technician qualied to disconnect the combustion product expulsion ducts and their subsequent
restoration.
For generators connected to the hydraulic system, a connection must be provided between the system itself and the product so that,
during extraordinary maintenance, carried out by a qualied technician, it is possible to move the generator by at least 50 cm from
adjacent walls without emptying the system (e.g. by using a double shut-o gate or suitable exible connection).
Air inlet
It is mandatory to provide an adequate external air inlet that supplies the combustion air required for the product to work properly. The
ow of air between the outside and the installation room can take place with a free air inlet or by channelling the air directly to the
outside3.
The free air inlet must:
• be made at oor level
• always be protected with an outer grille and in such a way that it cannot be obstructed by any object
• have a minimum total free area of 80 cm2 (net of the grille)
The presence of other suction devices (e.g.: vmc, electric fan for stale air extraction, kitchen hood, other stoves, etc.), in the same room
could cause negative pressure in the room. In this case, with the exception of sealed installations, one must verify that, with all the
equipment on, no more than 4 Pa of negative pressure is created inside the installation room with respect to the outside. If necessary,
increase the air inlet section.
It is possible to duct the air required for combustion to the outside by connecting the external air inlet directly with the combustion air
inlet which is usually found on the back of the appliance.
The duct must comply with the following dimensions (each 90° bend is equivalent to one linear metre):
3in the event the combustion air is ducted on unsealed products, still verify that no more than 4 Pa of negative pressure is created inside the installation room with respect to the
outside, otherwise provide for an additional air intake in the room.

Preparing the smoke expulsion system
The combustion product expulsion system is a particularly important element for the proper operation of the appliance and must be
correctly sized according to EN 13384-1.
Its creation/adaptation/verication must always be carried out by a legally qualied operator and must comply with the regulations in
force in the country where the appliance is installed.
The Manufacturer declines all liability for malfunctions caused by a badly sized and non-compliant smoke expulsion system.
Smoke duct (smoke tting)
The smoke duct is the pipe that connects the appliance to the ue.
This smoke tting must comply in particular with the following requirements:
• comply with product standard EN 1856-2;
• its cross-section must be of constant diameter and no less than that of the appliance outlet, from the rebox outlet up to the
connection in the ue;
• the horizontal section must be as short as possible and extend no more than 4 metres;
• the horizontal sections must have a minimum upward slope of 3%;
• changes of direction must have an angle no greater than 90° and be easy to inspect
• the number of changes of direction, including that for entry into the ue, and exclusion of theT in the event of a side or rear outlet,
must not exceed 3;
• it must be insulated if it passes outside the installation room
• it must not in any case cross rooms in which it is forbidden to install combustion appliances.
• the use of exible metal and bre cement or aluminium hoses is forbidden;
In any case, smoke ducts must be sealed against combustion products and any condensation. For this reason, it is recommended to use
pipes with silicone gaskets or similar sealing devices that withstand the operating temperatures of the appliance (e.g. T200 P1) and that
by removing the gaskets, are stillT400 N1 G certied.
Flue (chimney or piped duct)
When creating the ue, in particular comply with the following requirements:
• comply with the applicable product standard (EN 1856, EN 1857 EN 1457, EN 1806, EN 13063..);
• be made with suitable materials to ensure resistance to normal mechanical, chemical, thermal stresses and have adequate thermal
insulation in order to limit the formation of condensate;
• have a predominantly vertical conguration and be free of choke points along its entire length;
• be correctly spaced by air gaps and isolated from combustible materials;
• the ue inside the house must still be insulated and can be inserted in an air shaft provided it complies with the regulations for
piping;
• the smoke duct must be connected to the ue by means of aTee tting with an inspectable collection chamber for the collection of
soot and any condensate.
• where the sizing provides for wet operation, a suitable condensate collection and siphon discharge system must be set up.
We recommend checking the data plates of the ue for the safety distances that must be observed in the presence of
combustible materials and, if necessary, the type of insulating material to be used.
It is forbidden to connect the stove to a collective or shared ue (*) with other combustion appliances or with hood
outlets.
It is forbidden to use the direct drain on the wall or towards indoor spaces and any other form of drain not provided
for by the regulation in force in the country of installation.

Chimneypot
The chimneypot, meaning the end part of the ue, must meet the following characteristics:
• the smoke outlet section must be at least double the internal section of the chimney;
• prevent the penetration of rain or snow;
• ensure the outlet of smoke even in the event of wind (windproof chimneypot);
• the height of outow must be beyond the reux area (*) (refer to national regulations to identify the reux area);
• always be built at a distance from antennas or dishes, and never be used as a support.
(*) unless there are specic national derogations (clearly specied in the corresponding instruction manual in English) which under
appropriate conditions allow it; in this case, strictly follow the product/installation requirements of the relative regulations/technical
specications/legislation in force in that country.

EXAMPLES OF INSTALLATION4(DIAMETERS AND LENGTHS TO BE SIZED)
1. Flue installation with hole for the passage of the pipe
increased by:
• minimum 100mm around the pipe if next to
non-ammable parts such as cement, brick, etc.; or
• minimum 300mm around the pipe (or as
required by plate data) if next to ammable parts such
as wood etc.
In both cases, install suitable insulation between the ue
and the ceiling.
Always check and comply with the plate data of the
ue, specically the minimum safety distances from
combustible materials.
The previous rules also apply for holes made in walls.
2. Old ue, pipe with the inclusion of an external access
door for chimney cleaning.
3. External ue made of insulated stainless-steel pipes,
i.e. with double walls: all securely mounted on the wall.
With windproof chimneypot.
4. Ducting system using Tee ttings that allow easy
access for cleaning without having to remove the pipes
