1-WARNINGS AND WARRANTY CONDITIONS
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 modified without
authorisation.
All parts must be replaced with original spare parts.
WARNINGS FOR THE 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 differentiated waste collection centre set up by the local authorities or to a retailer that provides this service.
Separating and recycling prevents potential negative effects on the environment and health (often caused by inappropriately disposing of
product parts). It also allows materials to be recovered in order to obtain significant 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
efficiency” 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 efficiency 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 offers different 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 calorific 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.
BAG OF PELLETS 15 kg
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 certifications 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 certifications include, for example, ENPlus, DINplus, Ö-Norm M7135, and in particular,
guarantee the following characteristics:
•
•
•
•
•
•
•
calorific 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 certified fuel for its products (ENplus, DINplus, Ö-Norm M7135).
Poor quality pellets or others that do not comply with the characteristics specified previously may compromise the
operation of your product and can therefore make the guarantee and product liability invalid.

2-INSTALLATION
FOREWORD
The installation position must be chosen according to the room, smoke extraction system and flue. Check with local authorities whether
there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the flue or the chimney pot. 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
qualified technician, who must issue a declaration of conformity of the system to the purchaser and will assume full responsibility for final
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 reflux of smoke in the room
• smoke extraction takes place in total safety (sizing, smoke seal, distances from flammable materials..).
We especially recommend to check the data tags of the flue 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 flue. It is forbidden to install the stove in rooms with a fire hazard.
Installation in studio flats, 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 effective aeration
of the appliance and a good distribution of heat in the room. Comply with the distances from flammable or heat-sensitive objects (sofas,
furniture, wood panelling, etc.) as specified below. The frontal distance from flammable materials must be at least as specified 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 floor is made of wood, it is recommended to fit a floor protection sheet in compliance with the Standards in
force in the country of installation.

If the floor 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 floor 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 efficient and correct flue but is under no circumstances to substitute the regulations in
force, which the qualified 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 flue or the chimney pot.
The company declines all liability relating to the poor functioning of the stove if this is due to the use of an insufficiently sized flue in
violation of the Standards in force.
FLUE
The flue 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 efficiency with cooler flue gasses and consequently less draught, it is therefore essential that the
flue is built up to standard and always kept in perfect working order. A flue that serves a pellet/wood fuelled appliance must be at least
category T400 (or greater if the appliance requires so) and resistant to soot fires. Smoke must be extracted through a single flue made of
insulated steel (A) or an existing flue 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 flue.
min.3,5 metri
(*) unless there are national derogations (for instance in Germany), which under suitable conditions allow for the installation of several
appliances in the same fireplace. In any case, strictly follow the product/installation requirements of the relative regulations/legislation

TECHNICAL CHARACTERISTICS
Have the efficiency of the flue checked by an authorised technician.
The flue must be sealed against flue 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 fireplaces 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 flammable materials with an air gap or insulating materials: check the distance
specified by the manufacturer of the fireplace 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 flue 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 flue 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
configurations must be correctly sized in accordance with the general method of calculation of UNI EN13384-1 or other proven efficiency
methods.
Below is a list of some flues available on the market:
AISI 316 steel chimney with
double chamber insulated with
ceramic fibre or equivalent
resistant up to 400°C.
Refractory chimney with Traditional square-section clay
double insulated chamber and chimney with insulating empty
external lightweight concrete inserts.
cladding with cellular material
such as clay.
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 flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draught and thus
compromising the efficient operation of the stove and, if large build-ups accumulate, can catch fire. The flue and chimney pot must be
cleaned and checked by a qualified chimney sweep at least once a year. Once the inspection/maintenance has been performed, request a
written report that the system is safe.
Cleaning is critical to the safety of the system
CHIMNEYPOT
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 flue/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 outflow into
the atmosphere must be beyond the
reflux 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
flow 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 fire 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 flow 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 floor 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 flats, 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.

withstand the high operating temperatures of the appliance (min. T200 class P1). The use of flexible metal hoses made of fibre
cement or aluminium is forbidden. For direction changes, we always recommend the use of a T fitting 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 flammable or heat-sensitive structures.

Attention! It is mandatory to install the vents with “V” netting (1 or 2 depending on the type of appliance) on the
rear “S” output for safety purposes and to prevent the rear wall from being hit directly by the hot air flow, generating
halos, blackening or even dangerous heating in the case of flammable walls.
When positioning the stove near a wall (see image below) direct the hot air “V” vent towards the free part.
If this warning is not complied with, the manufacturer cannot be held liable for any damage to property and/or

8-LOADING THE PELLETS
LOADING THE PELLETS
Fuel is loaded from the upper part of the stove by lifting door “W”.
Pour the pellets in slowly so that they are deposited at the bottom of the hopper.
If loading pellets when the stove is running, open the door of the tank using the stove mitten that comes with the
stove itself.
When loading, do not let the pellet bag come into contact with hot surfaces.
Never remove the protection grid inside the hopper.
No other type of fuel other than pellets is to be inserted into the hopper, in compliance with above-mentioned
specifications. Store the spare fuel at an adequate safe distance.
Do not pour pellets directly onto the brazier but only into the hopper.
When the appliance is running and when it is turned off, most of the stove surfaces are very hot (door, handle, glass,
smoke outlet pipes, etc.). Therefore it is recommended to avoid coming into contact with these parts.
