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
•The type of pellets used must comply with the current EN ISO 17225-2 class A1 regulation. Fir pellets are usually 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).
•With wood-burning appliances, the fuel must comply with the current EN ISO 17225-5 class A1 regulation. Check the correct moisture
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 and V1) in manual mode.
The other conditions (COMFORT SETTING) correspond to intermediate ventilation and power.

6
1-WARNINGS ANDWARRANTY CONDITIONS
•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

2-INSTALLATION
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
Wood pellets are manufactured by extruding sawdust which is produced during the processing of natural dried wood (without paint).
The compactness of the material is guaranteed by the lignin contained in the wood itself and allows the pellets to be produced without
glue or binders.
The market oers dierent types of pellets with characteristics that vary according to the wood mixtures used. The diameter varies
between 6 and 8 mm, with a standard length ranging from 3 to 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 (ex EN 14961). 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 (max 5% bark).
•Packaging: in sacks made from ecologically compatible or biologically decomposing material.
The company strongly recommends using certied fuel for its products (ENplus, DINplus, Ö-Norm M7135).
Poor quality pellets or others that do not comply with the characteristics specied previously may compromise the
operation of your product and can therefore make the guarantee and product liability invalid.

FOREWORD
The installation position must be chosen according to the room, smoke extraction system and ue. Check with local authorities whether
there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the ue or the chimneypot.The
manufacturer declines all responsibility in the event of installations that do not comply with the laws in force, incorrect room air exchange,
electrical connection non-compliant with the standards and inappropriate use of the appliance. The installation must be carried out by
a qualied technician, who must issue a declaration of conformity of the system to the purchaser and shall assume full responsibility for
nal installation and consequent good operation of the product.
In particular one must ensure that:
•there is a suitable combustion air inlet and smoke outlet in compliance with the type of product installed
•other stoves or devices installed do not cause negative pressure in the room where the product is installed (for sealed appliances only,
a maximum of 15 Pa of negative pressure in the room is allowed)
•when the product is switched on there is no reux of smoke in the room
•smoke extraction takes place in full safety (sizing, smoke seal, distances from ammable materials...).
We especially recommend checking the data plates of the ue for the safety distances that must be observed in the
presence of combustible materials and the type of insulating material to be used. These indications must be followed
strictly to prevent serious harm to people and to the integrity of the home. Installation of the appliance must ensure easy access
to clean the appliance itself, the smoke outlet pipes and the ue. It is forbidden to install the stove in rooms with a re hazard.
Installation in studio ats, bedrooms and bathrooms is only permitted with sealed or closed appliances equipped with
suitable combustion air ducting directly outside. Always maintain adequate distance and protection in order to prevent
the product from coming into contact with water.
If there are several appliances installed, the external air inlet must be sized accordingly.
MINIMUM DISTANCES
It is recommended to install the stove detached from any walls and/or furniture, with a minimum clearance to allow eective aeration
of the appliance and a good distribution of heat in the room. Comply with the distances from ammable or heat-sensitive objects (sofas,
furniture, wood panelling, etc.) as specied below. The frontal distance from ammable materials must be at least as specied in the
product’s technical data table.
If there are particularly delicate objects such as furniture, curtains or sofas, increase the stove distance accordingly.
If the oor is made of wood, it is recommended to t a oor protection sheet in compliance with the standards in
force in the country of installation.

FOREWORD
This Flue chapter has been drawn up with reference to the provisions of European Standards (EN13384 - EN1443 - EN1856 - EN1457).
The chapter provides indications for installing an ecient and correct ue but is under no circumstances to substitute the regulations in
force, which the qualied manufacturer must be in possession of. Check with local authorities whether there are any restrictive regulations
in force regarding the combustion air inlet, the smoke outlet system, the ue or the chimneypot.
The Company declines all liability relating to the poor functioning of the stove if this is due to the use of an insuciently sized ue in
violation of the standards in force.
FLUE
The ue or chimney is of great importance for the proper operation of a solid fuel-burning heating appliance with forced draught. As
modern heating appliances have high eciency with cooler ue gases and consequently less draught, it is therefore crucial for the ue
to be built to professional standard and always kept in perfect working order. A ue for a pellet/wood red appliance must be at least
category T400 (or greater if the appliance requires so) and resistant to soot res. Smoke must be extracted through a single ue made of
insulated steel (A) or an existing ue that complies with the intended use (B).
A simple air shaft made of cement must be suitably piped. In both solutions there must be an inspection cap (AT) and/or inspection access
panel (AP) - FIG.1.
It is prohibited to connect more than one wood/pellet appliance (*) or any other type of appliance (cowl vents ...) to the same ue.
(*) unless there are national derogations (for instance in Germany), which under suitable conditions allow for the installation of several
appliances in the same replace. In any case, strictly follow the product/installation requirements of the relative regulations/legislation
in force in that country

TECHNICAL SPECIFICATIONS
Have the eciency of the ue checked by an authorised technician.
The ue must be sealed against ue gases, in a vertical direction without narrowing, be made with materials impermeable to smoke,
condensation, thermally insulated and suitable to resist normal mechanical stress over time (we recommend replaces made of A/316
or refractory material with insulated round section double chamber). It must be suitably insulated externally to avoid condensation
and reduce the smoke cooling eect. It must be separated from combustible or easily ammable materials via an air gap or insulating
materials: check the distance specied by the chimney manufacturer according to EN1443. The chimney opening must be in the same
room as the appliance, or at most in the adjoining room, and have a soot and condensation collection chamber beneath the opening, and
be accessible via a sealed metal door.

SIZING
The negative pressure (draught) of a ue also depends on its height. Check the negative pressure with the values indicated in the technical
specications.The minimum height of the chimney is 3.5 metres.
The interior cross-section of the ue can be round (best solution), square or rectangular (the ratio between the internal sides must be
≤1.5) with the sides joined with a minimum radius of 20 mm. The dimension of the cross-section must be minimum Ø100mm.
The cross sections/lengths of chimneys must be correctly sized in accordance with the general method of calculation of UNI EN13384-1 or
other proven eciency methods.

MAINTENANCE
The ue must be kept clean, since the deposit of soot or unburnt oils reduces the cross-section, blocking the draught and thus
compromising the ecient operation of the stove and, if large build-ups accumulate, can catch re. The ue and chimneypot must be
cleaned and checked by a qualied chimney sweep at least once a year. Once the inspection/maintenance has been performed, request a
written report that the system is safe.
Failure to perform cleaning jeopardises the system’s safety.
CHIMNEYPOT
The chimneypot is a crucial element for correct operation of the heating appliance: we recommend a windproof chimneypot (A), see
Figure 7.
The area of the opening for smoke
extraction must be at least double the
cross-section of the ue/piped system,
and arranged so that the smoke outlet is
ensured even in the presence of strong
wind. The chimneypot must prevent
rain, snow or animals from entering the
chimney. The height of outow into the
atmosphere must be beyond the reux
area caused by the shape of the roof or any
nearby obstacles (see Figures 2-3-4-5-6).

EXTERNAL 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 may be direct, through an inlet in an external wall of the room (preferable
solution see Figure 9 a), or indirect, via air intake from adjoining rooms and connecting permanently with the installation room (see Figure
9 b). Adjoining areas may not include sleeping areas, bathrooms, garages or in general areas with a re hazard. During installation it is
required to check the minimum clearances required to draw air from outside. Take into account the presence of doors and windows that
could interfere with the proper ow of air to the stove (see diagram below).
The air inlet must have a minimum net total area of 80 cm2: the surface must be increased accordingly if there are other active generators
(for example: electric fan for stale air extraction, range cooker hood, other stoves, etc.), which could cause a depression in the room. Make
sure that, with all appliances on, the pressure drop between the room and the outside does not exceed the value of 4 Pa (also for Oyster
appliances if the combustion air has not been suitably ducted outside). If required, increase the intake section of the air inlet, which must
be made at oor level and always protected with a bird-proof outer protection grid and in such a way that it cannot be obstructed by any
object.
It is possible to connect the air required for combustion
directly to the outside air inlet, by using a pipe of at
least Ø50mm, with maximum length of 3 linear
metres. Each pipe bend must be considered equivalent
to a linear metre. To attach the pipe see the rear of the
stove.
For stoves installed in studio ats, bedrooms and
bathrooms (where allowed), it is mandatory to
connect the combustion air outside. Specically for
sealed stoves the connection must be sealed in order
not to compromise the overall sealing of the system.

1.5 m AT A DISTANCE from smoke outlet
CONNECTION TO THE FLUE
The connection between the ue and the appliance must be via a smoke duct compliant to EN 1856-2. The connecting section must
extend no more than 4 m horizontally, with a minimum slope of 3% and with a maximum of 3 x 90° bends (accessible for inspection - do
not count theTee tting at the appliance outlet).
The diameter of the smoke duct must be equal to or greater than that of the outlet of the appliance (Ø 80 mm).

Use a smoke duct according to the regulations in force in the country of installation and verify that it is compatible with the product and
installation characteristics.The temperature class of the smoke duct must exceed operating temperatures of the appliance.
It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from hoods above it. It is forbidden to extract
the combustion products directly through the wall, whether towards indoor spaces or outdoors.
Should there be ammable or heat-sensitive structures, the smoke duct must respect the safety distances specied in the data plate.

EXAMPLES OF CORRECT INSTALLATION
1. Installation of Ø120mm ue 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, minimum pipe Ø100mm 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 minimum Ø100mm: all securely
mounted on the wall. With windproof chimneypot. See
g. 7 type A.
4. Ducting system using Tee ttings that allow easy
access for cleaning without having to remove the pipes
