SPARE PARTS
In the event of a malfunction, consult the retailer who will forward the call to the Technical Assistance Department.
Only use original spare parts. The retailer or service centre can provide all necessary information regarding spare parts.
We do not recommend waiting for the parts to get worn out before having them replaced. It is important to perform regular maintenance.
The company declines all liability if the product and any other accessory is used improperly or modied without
authorisation.
All parts must be replaced with original spare parts.
WARNINGS FORTHE CORRECT DISPOSAL OF THE PRODUCT.
The owner is the sole party responsible for demolishing and disposing of the product. This must be performed in compliance with laws
related to safety and environmental protection in force in his/her country.
At the end of its working life, the product must not be disposed of as urban waste.
It must be taken to a special dierentiated waste collection centre set up by the local authorities or to a retailer that provides this service.
Separating and recycling prevents potential negative eects on the environment and health (often caused by inappropriately disposing of
product parts). It also allows materials to be recovered in order to obtain signicant savings in energy and resources.
WHY SEALED
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 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 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.

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 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 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), 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.
• 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 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 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 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 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 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.
Non-ammable walls Flammable walls

If the oor is made of combustible material, it is recommended to use protection made of non-combustible material (steel, glass...) that
also protects the front from falling combusted material during cleaning operations.
The appliance must be installed on a oor with adequate load capacity.
If the existing construction does not meet this requirement, one must take appropriate measures (for example a load distribution plate).

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 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 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 negative pressure (draught) of a ue depends on its height. Check the negative pressure 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
15x30).

MAINTENANCE
The ue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draught and thus
compromising the ecient operation of the stove and, if large build-ups accumulate, can catch re. The ue and chimney pot 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 chimneypot is a crucial element for the heating appliance to work properly: we recommend a wind proof chimneypot (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
outlet 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 (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, 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 intake must have a minimum total net area of 80 cm2: the surface must be increased accordingly if within the room there are
other active generators (for example: electric fan for stale air extraction, kitchen hood, other stoves, etc...), which could cause 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.
It is possible to connect the air required for combustion
directly to the outside air inlet, with a pipe of at least
Ø50mm, with maximum length of 3 linear metres;
each pipe bend shall be considered equivalent to a
linear metre. To attach the pipe see the back of the
stove.
For stoves installed in studio ats, bedrooms and
bathrooms (where allowed), it is mandatory to
connect the combustion air outside. In particular for
sealed stoves the connection must be sealed in order
not to compromise the overall sealed characteristic of
the system.

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 conforms 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 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.

2-INSTALLATION
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 windproof 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
