SPARE PARTS
In the event of a malfunction, consult the retailer who will forward the call to the Technical Assistance Service.
Use only 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 be worn 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 OYSTER
Products constructed with the Oyster technology do not consume the room’s oxygen thanks to their perfectly airtight structure, but take
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.

2-INSTALLATION
The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always
observe the domestic regulations in force.
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.
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 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. (formerly 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 render the guarantee and product liability invalid.

FOREWORD
The installation position must be chosen according to the room, to the smoke extraction system, to the chimney 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 chimney cap. 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 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
• fumes 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.Observe distances from ammable or heat-sensitive objects (sofas, furniture,
wood panelling, etc..) as specied below.The front distance from ammable materials must be at least as set out 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
EGO 2.0 AIR OYSTER A = 5 cm

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
This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856
- EN1457).
The chapter provides indications for installing an ecient and correct smoke 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 chimney.
The company declines all liability relating to the poor functioning of the boiler if this is due to the use of an insuciently sized ue in
violation of regulations in force.
SMOKE 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, 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 in 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.

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
watertight metal hatch.

DIMENSIONING
The drop in pressure (draft) of a ue depends on its height. Check the drop in pressure with the values indicated in the technical
characteristics.The minimum height of the chimney is 3.5 meters.
The interior cross-section of the ue can be circular (best variation), square or rectangular (the ratio between the interior 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 dimensioned 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:
Steel chimney AISI 316 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 draft and thus compromising
the ecient functioning of the heater and, if large build-ups accumulate, can catch re. The ue and chimney must be cleaned and
checked by a skilled chimney sweep at least once a year. Once the check/maintenance has been performed, request a signed report stating
that the system is safe.
Failure to clean the system jeopardises its safety.
CHIMNEY
The chimney is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney (A), see Figure 7.
The area of the opening for smoke extraction must be at least double the cross-section of the smoke duct/ue 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 zone created by 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 intake 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 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 cause depression
in the room. A check must be carried out to ensure that, with all equipment on, the pressure drop between the room and the outside does
not exceed a value of 4 Pa. (also for Oyster appliances if 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.

Technical Dept. - All rights reserved - Reproduction is prohibited
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
maximum length 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.
In the event a longer connection should be required, further extend with an 80mm smooth pipe. In any case do not exceed 8 linear metres
of ducting (also taking into account the elbows).
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 UNDER 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 AWAY from smoke outlet
CONNECTION TO FLUE
The connection between the ue and the appliance must be via a smoke duct that conforms with EN 1856-2. The connecting section
must extend no more than 4 m horizontally, with a maximum incline of 3% and containing a maximum of 3 90% bends (accessible for
inspection - do not count the T joint at the appliance outlet).
The diameter of the smoke duct must be equal to or greater than that of the appliance outlet (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 tubes in bre cement
or aluminium is prohibited. For direction changes, we always recommend the use of aT joint with an inspection cap allowing
easy access for cleaning the tubes. Always ensure that the inspection cap is replaced and hermetically sealed with the seal in tact after
cleaning.
It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from overhead cowling. It is prohibited to
extract the products of combustion directly through the wall, whether into indoor spaces or outdoors.
The smoke duct must be a minimum distance of 400 mm from ammable or heat-sensitive structures.

2-INSTALLATION
EXAMPLES OF CORRECT INSTALLATION
1. Installation of Ø150mm ue with hole for the passage
of the tube increased by:
minimum 100 mm around the tube if next to non
ammable parts such as cement, brick, etc.; or
minimum 300 mm around the tube (or as prescribed by
data tags) 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. See g.
7 type A.
4. Ducting system usingT joints that allow easy access for
cleaning without having to remove the tubes
