PRODUCT PERFORMANCE CHECKS.
All our products undergo ITT tests carried out by a notied laboratory (system 3) and in accordance with (EU) regulation number 305/2011
“Construction products”, according to standard EN 14785:2006 (pellets) and“Machinery Directive”EN 303-5 (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.
• use the average draught of the combustion smoke specied in the“technical product features”table.
• the type of pellets used must comply with current EN ISO 17225-2 regulations.
• the amount of fuel may vary according to the length and caloric value of the fuel.This may require some adjustments to stay in line
with the hourly consumption specied in the “technical product features” table. A1 pellets ensure an overall caloric value within
tight margins compared to the test pellets used. However, size considerably inuences performance, so on average it must not be
less than 24 mm long and with a 6mm diameter.
• in the case of a wood-burning product, check the correct residual moisture content of the fuel, which must not be less than 12% or
more than 20%. As the moisture increases, dierent combustion air settings are required. The settings are to be carried out via the
combustion air register, thereby modifying the mixture between primary and secondary air.
• it is necessary to check the operation of devices that can aect performance (for example air fans or electrical safety devices) in case
of damage due to handling.
• maximum performance can be achieved at the maximum ame and ventilation power.
• strictly comply with the withdrawal points specied in regulations both in terms of emissions and temperature.

Information for management of waste electrical and electronic equipment containing batteries and
accumulators
This symbol appears on the product, on the batteries, on the accumulators or on their packaging or on their documentation; it indicates
that the product and the batteries or the accumulators included must not be collected, recycled or disposed of with household waste at
the end of their service life.
Improper management of waste electrical and electronic equipment, batteries or accumulators can cause the hazardous substances
contained within to leak out. In order to safeguard the environment and health, the user is required to separate this equipment, and/or
the batteries or accumulators included, from other types of waste and take them to the local collection centre.The distributor can be asked
to collect the waste electrical and electronic equipment under the conditions and according to the procedures laid down by Legislative
Decree 49/2014.
Separate collection and correct treatment of waste electrical and electronic equipment, batteries and accumulators contribute to
conserving natural resources, respect for the environment and ensure the protection of health.
For more information on collection centres for waste electrical and electronic equipment, batteries and accumulators, contact the
competent public Authorities for issue of the authorisations.
WHY A SEALED STOVE?
Products constructed with a perfectly sealed structure do not consume the room’s oxygen but draw all the air form the outer environment
(if suitably ducted) and may therefore be installed in all dwellings 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 intakes and relevant aeration
grilles are required in the installation premises.
Consequently, there will be no more drafts of cold air in the room, which make it less comfortable and reduce the overall eciency of the
system.The sealed stove may even be installed in the presence of forced ventilation or in premises that might have negative pressure with
respect to the outside.

2014/30/EU (EMC - Electromagnetic Compatibility directive)
2014/53/EU (RED – Radio Equipment directive)
2011/65/EU (ROhS)
Having specied the above, we highlight and report that:
• This manual and technical data sheet, also available on our website, bear all of the specic indications and necessary and
essential information to choose the product, to install it correctly and to properly size the smoke expulsion system;
• the Products must be installed, controlled and serviced by qualied personnel, according to the instructions in this manual
and in compliance with local laws and installation and maintenance standards in force in individual countries, so as to provide an
ecient heating system, properly sized according to the needs of the home;
• if the Products are thermally stressed, constantly operating for several hours at high power (e.g. 3, 4 hours a day at outputs P4
or P5), we recommend more frequent cleaning and reducing the interval between routine maintenance operations according to the
operating condition of the product. We furthermore point out that these operating conditions increase the risk of premature wear of
the product, especially those parts exposed to the direct heat of the re (e.g. combustion chamber), the original condition of which
can undergo modications and deterioration which, among other things, could generate noise during operation of the unit due to
mechanical expansion.
The manufacturer will not be held liable if the above information is ignored.
We therefore recommend, in addition to complying with the cleaning, routine and extraordinary maintenance instructions provided, to
make meticulous use of the unit using the intended Timer and modulation programs, to correctly manage the internal temperature of

PELLETS
Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The
compactness of the material is guaranteed by the lignin contained in the wood itself and allows 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 most common
diameter on the market is 6 mm (although 8 mm diameter is available too) with a length, on average, of between 3 and 40 mm. A good
quality pellet has a density of between 600 and 750 or more kg/metres cubed and a water 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), whereas 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 must
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 in particular,
guarantee the following characteristics:
• caloric value: 4.6 ÷ 5.3 kWh/kg.
• Moisture 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 substances (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 will 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 exhaust in compliance with the type of product installed
• other stoves or devices installed do not cause depression in the room where the product is installed (for sealed appliances only, a
maximum of 15 Pa of depression 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 total safety (sizing, smoke seal, distances from ammable materials..).
We especially recommend to check the data tags of the ue for the safety distances that must be observed in 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 the integrity of the home. The installation of the appliance must ensure easy access to
clean the appliance itself, the smoke exhaust 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 allowed 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.
In the event 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 particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance 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
The Chimney 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 technician must be in possession of. Check with local authorities whether there are any restrictive regulations in
force regarding the intake of air for combustion, the smoke extraction 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 natural draught, as
modern heating appliances have high eciency with cooler ue gasses and consequently less draught, it is therefore essential that the
ue is built up to standard and always kept in perfect working order. A ue that serves a pellet/wood fuelled 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 lined. In both solutions there must be an inspection cap (AT) and/or inspection hatch
(AP) - FIG.1.
It is prohibited to connect more than one wood/pellet (*) or any other type of appliance (vent cowling...) 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 CHARACTERISTICS
Have the eciency of the ue checked by an authorised technician.
The ue must be sealed against ue gasses, 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). Be suitably insulated externally to avoid condensation and reduce
smoke cooling. It should be separated from combustible or ammable materials with an air gap or insulating materials: check the distance
specied by the manufacturer of the replace 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 hatch.

SIZING
The draught of a ue depends on its height. Check the draught with the values indicated in the technical characteristics. The minimum
height of the chimney is 3.5 metres.
The interior cross-section of the ue can be round (best), 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 the chimneys shown in the technical data tables are indications for correct installation. Any alternative
congurations must be correctly sized in accordance with the general method of calculation of UNI EN13384-1 or other proven eciency
methods.
Below is a list of some ues available on the market:
AISI 316 steel chimney with
double chamber insulated with
ceramic bre or equivalent
resistant up to 400°C.
Refractory chimney with
double insulated chamber and
external lightweight concrete
cladding with cellular material
such as clay.
Traditional square-section clay
chimney with insulating empty
inserts.
Avoid products with an internal
rectangular section where the
larger side is 1.5 times the
smaller side (e.g. 20x40 or

MAINTENANCE
The ue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft 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.
CHIMNEY POT
The chimney pot is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney pot (A), see Figure
7.
The area of the opening for smoke
extraction must be at least double
the cross-section of the ue/lined
system, and arranged so that smoke
extraction is ensured even in strong
wind. The chimney 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 due to the shape of the roof
or any obstacles near the outlet (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; 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, garages or general areas with a re hazard. During installation one must check the minimum clearances required for air
intake 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, 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 necessary 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.

2-INSTALLATION
In order to fully enhance the sealed features and heating performance of this Oyster appliance, and thus to avoid tting a free air intake
in the room, It is recommended to connect the air required for combustion directly to the external air intake through 60 mm piping
with a maximum length of 3 linear metres, using the suitable“j”48/60 adapter supplied with the appliance; each pipe elbow must be
considered as equivalent to one linear metre. If a longer connection should be required, increase further with an 80 mm smooth pipe.
However, do not exceed 8 linear metres of ducting (considering the curves too). In sealed stoves the connection must be sealed in order
not to aect the overall sealed features of the system.
For stoves installed in studio ats, bedrooms and bathrooms (where allowed), it is mandatory to connect the combustion air outside.
DISTANCE (metres) The air inlet must be at a distance of:
1.5 m BELOW Windows, doors, smoke outlets, cavities, ....
1.5 m HORIZONTALLY Windows, doors, smoke outlets, cavities, ....
0.3 m ABOVE Windows, doors, smoke outlets, cavities, ....
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 that complies with 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 90° bends (accessible for inspection - do
not count theT 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 smoke ducts with a diameter of 80mm or 100mm depending on the type of system, with silicone gaskets or similar gaskets that can
withstand the high operating temperatures of the appliance (min. T200 class P1). The use of exible metal hoses made of bre
cement or aluminium is forbidden. For direction changes, we always recommend the use of a T tting with an inspection cap
allowing easy access for cleaning the tubes. Always ensure that the inspection cap is put back in place and sealed hermetically with the
relevant seal intact after cleaning.
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 into indoor spaces or outdoors.
The smoke duct must be at a minimum distance of 400 mm from ammable or heat-sensitive structures.

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
rating plate) if next to ammable parts such as wood etc.
In both cases, install suitable insulation between the ue
and the ceiling.
Always check and respect the data tags on the ue,
in particular 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 wind-proof chimney pot. See
g. 7 type A.
4. Ducting system using T ttings that allow easy access
for cleaning without having to remove the pipes.
