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 take the following warnings into account:

• 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“product technical specications”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“product technical specications”table. A1 pellets ensure an overall caloric value

within tight margins compared to the test pellets used. However, size considerably aects performance, therefore 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 required 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 required by regulations both in terms of emissions and temperature.

1-WARNINGS ANDWARRANTY CONDITIONS

SPARE PARTS

In the event of a malfunction, consult the retailer who shall 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 crucial to perform regular maintenance

checks.

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.

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 avoid harming the environment or health, the user is required to separate this equipment, and/

or the batteries or accumulators included, from other types of waste and deliver 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 SEALED

Products constructed with a perfectly sealed structure do not consume the room’s oxygen but draw all the air from the outer environment

(if suitably ducted) and may therefore be installed in all houses 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 on the installation premises.

Consequently, there will be no more draughts of cold air in the room, which make it less comfortable and reduces 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 extruding sawdust which is produced during the processing of natural dried wood (without paint).

The compactness of the material is guaranteed by the lignin contained in the wood itself and allows the 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 also available) with a length, on average, between 3 and 40 mm. A good quality pellet

has a density of between 600 and 750 or more kg/cubic metres 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), 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 specically

assure that the following characteristics are complied with:

• 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 warranty and product liability invalid
