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 oers dierent 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 caloric 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.
15 Kg BAG OF FUEL
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 certications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2
according to EN14961-2. These certications include, for example, ENPlus, DINplus, Ö-Norm M7135, and in particular, guarantee the
following characteristics:
• caloric value: 4.6 ÷ 5.3 kWh/kg.
• Moisture content: ≤ 10% of the weight.
• Percentage of ash: max 1.5% of the weight.
• 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 certied fuel for its products (ENplus, DINplus, Ö-Norm M7135).
Poor quality pellets or others that do not comply with the characteristics specied previously may compromise the
operation of your product and can therefore render the guarantee and product liability invalid.

2 - INSTALLATION INSTRUCTIONS
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 qualied 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 reux 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 eective 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 specied 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.
Distance from ammable material (see p.18)
FLUX HYDRO
side = 2 cm (MIN. 30 cm to open the door)
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).

2 - INSTALLATION INSTRUCTIONS
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 ecient and correct smoke ue but is under no circumstances to substitute the
regulations in force, which the qualied 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 insuciently 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 eciency 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.
The stove must be connected to a ue pipe or an internal or external vertical duct conforming to EN 1856-1-2 to suit the
appliance and types of fuels to be burnt – refer to detailed guidance in sections 2, 3 and 4 in ADJ (ONLY FOR UK).

TECHNICAL CHARACTERISTICS
Have the eciency 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
specied 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.
