above and from non-compliant product installation.
Install the stove according to the regulations in force in the country of use.
For example, in Italy this refers to UNI 10683: 2012, which dictates 4 points:
1. preliminary activities - for which the retailer/installer is responsible and liable for at the time of the inspection before definiti e installation.
The preliminary acti ities include:
• installation site suitability erification;
• fume e acuation system suitability erification;
• external air inlet suitability erification.
At this stage it is necessary to check that the product can be safely operated and that it satisfies its technical characteristics.
The safety conditions must be ascertained by means of a prior inspection.
Stoves and fireplaces are heating systems and must be installed safely and comply with the manufacturer's instructions!
2. installation - responsibility of the installer. At this phase the aspects of installation of the product and of the fume e acuation system are
taken into account and the following issues are addressed:
• Safety distance from combustible materials;
• Chimney flue construction, smoke ducts, intubated systems and chimney cowls.
3. issuing of additional documents - responsibility of the installer.

Use a ent pipe and an anti-corrosion fume connection to the ent pipe. The temperature of the pellet sto e fumes is ery low.
It could create condensation and corrode the fume exhaust.

03 PRODUCT INSTALLATION
11
The ent pipe is one of the key features to guarantee correct functioning of the sto e. Thanks to the quality of the materials, the strength,
the durability, the easy cleaning and maintenance, the best ent pipes are made of steel, either stainless steel or aluminised.
•The sto e is fitted with a round fume outlet and a joint connection to be connected to the ent pipe.
•Use telescopic joint connections to facilitate connection to the steel rigid ent pipe and counterbalance the thermal expansion of both
the firebox and the ent pipe.
•Seal the ent pipe joint connection with high temperature silicone sealant (1,000°C). Should the existing flue opening not be perfectly
perpendicular to the firebox fume outlet, use an elbow to connect them. Inclination must ne er exceed 45°, with respect to the ertical axis.
•No constrictions. Use 10 cm-thick insulating thimbles if pipe ent passes through floors.
•The ent pipe must be insulated along its entire length. Thanks to the ent pipe, insulation fume temperature will remain high
optimising draught, pre enting condensation and reducing the build-up of non-ignited particles along the ent pipe walls. Use proper
insulating materials (glass wool, ceramic fibre, Class A1 non-combustible materials).
•Install a ent pipe with a minimum ertical run of 2 m to guarantee proper draught.
•The ent pipe must be weather-proof and as linear as possible.
•Flexible and length-adjustable metal pipes may not be used.

03.3 C IMNEY COWL
A properly installed chimney cowl ensures optimum sto e functioning. The anti-downdraught chimney cowl consists of a number of components
whose outlet section sum always doubles the ent pipe section. Make sure the chimney cowl is at least 150 cm abo e the roof top so that it is
fully exposed to the wind.
The chimney cowls must:
•ha e useful outlet section that is at least twice that of the ent pipe.
•be made in such a way as to pre ent the penetration of rain or snow.
•be constructed in such a way as to ensure, in the e ent of winds coming from any direction, the e acuation of combustion products.
•be free of mechanical intake auxiliaries.

03.4 DRAUG T
Fumes heat up during combustion, increasing their olume. Their density is therefore lower than the one of the surrounding colder air.
This difference between the inside and outside temperatures of the chimney results in a negati e pressure which increases proportionally to the
ent pipe length and the temperature.
The draught must be stronger than the fume circulation resistance so that all exhaust fumes generated during combustion inside the sto e are
drawn upwards through the outlet and the ent pipe. Many weather conditions affect the ent pipe functioning, such as rain, fog, snow, altitude,
and wind being the most important as it can create both negati e pressure and dynamic loading.
The wind action aries depending on whether it is ascending, descending or horizontal.
•Ascending wind always results in an increased negati e pressure and draught.
•Horizontal wind results in an increased negati e pressure as long as the chimney cowl was properly installed.
•Descending wind always diminishes the negati e pressure, sometimes in erting it.
Excess draught causes an increase in the combustion temperature and consequently a loss of sto e efficiency.
Part of the combustion fumes is drawn up through the ent pipe together with small pellet particles before combustion reducing sto e efficiency,
increasing fuel consumption and resulting in the emission of polluting fumes.
At the same time the high fuel temperature, due to an excess amount of oxygen, wears down the combustion chamber sooner than expected.
On the other hand, poor draught slows down combustion resulting in a decrease in the sto e temperature, fume spillage inside the room, a loss
of sto e efficiency and dangerous build-up in the ent pipe.
In order to a oid excessi e draught it is appropriate to use:
Draught regulator

03. INSTALLING THE PRODUCT

03.5 STOVE EFFICIENCY
Highly efficient sto es may pose difficulties for fume extraction.
In order for a ent pipe to work properly its internal temperature must increase as a consequence of the fumes generated during combustion.
Importantly, the efficiency of a heater is determined by its ability to transfer most of the heat produced to the en ironment to be heated:
consequently, the greater the efficiency of the sto e, the "colder" the residual fumes of combustion, and consequently, the lower the "draft".
A traditional chimney flue, with a rough design and insulation, is more efficient if used with a traditional open fireplace or a poor quality sto e
where most of the heat is lost with the fumes.
Therefore, purchasing a quality sto e often entails modifying the existing chimney flue to obtain better insulation, e en when it already works
properly with old appliances.
Poor draught results in the sto e not operating when hot or in smoke spillage.
•Connecting the sto e pipe to an existing chimney flue that has already been used with an old appliance is a common mistake. In this
way two solid-fuel appliances share the same chimney flue, which is wrong and dangerous.
•If the two appliances are used simultaneously, the fume load might exceed the existing chimney flue capacity resulting in downdraught.
If only one appliance is used, the fume heat will facilitate draught but the cold air coming from the other appliance not in use will cool
down exhaust fume temperature again blocking the draught.
•Besides the problems described so far, if the two appliances are placed on different le els the communicating essel principle might
be interfered with, causing combustion fumes to be drawn in an irregular and unforeseeable way.

03.6 INSTALLATION
Using coaxial tubes the air will be pre-warmed contributing to impro ed combustion and lower emissions into the atmosphere.
Follow the instructions before installing your sto e:
Select the position where the sto e is to be installed and then:
•Arrange the connection to the ent pipe for fume extraction.
•Arrange the external air intake (combustion air).
•Arrange the connection to the earthed mains.
•The electrical system of the room where the sto e is to be installed must be earthed, otherwise the control board may not work properly.
•Place the sto e on the floor in a con enient position for the connection to the ent pipe and close to the "combustion air" intake.
•The appliance must be installed on a floor with an adequate loading-bearing capacity.
•Should the existing floor not comply with the requirement abo e, proper measurements must be taken (for instance, the installation
of a load distribution plate).
•All the structures which could catch fire if exposed to excessi e heat must be protected. Floors made from wood or inflammable
materials must be protected using non-combustible materials (e.g. 4 mm-thick sheet metal or ceramic glass).
•The appliance installation must ensure easy access for cleaning the sto e, exhaust pipes and ent pipe.
•This appliance is not suitable to be installed on a shared ent pipe.
•During normal operation, the sto e draws air from the room where it is installed. Therefore, an external air intake must be positioned
at the same height of the pipe located on the sto e back. Exhaust fume pipes must be suitable for pellet sto es and must therefore be
made from coated steel or stainless steel, with a diameter of 8 cm and fitted with adequate gaskets.

17
03. INSTALLING THE PRODUCT
•The combustion air intake must be connected directly to the outside or to adjacent rooms pro ided they are fitted with external air
supply ents and are not used as bedrooms or bathrooms or, whene er a fire hazard exists, as storage rooms, garages, combustible
material warehouses, etc. The air ents must be placed in such a way that they cannot be clogged either from the outside or inside
and must be protected using a grille, a metal mesh or other suitable means pro ided they do not reduce the minimum section.
•If the sto e is to be installed in rooms where it is surrounded by combustible materials (e.g. furniture, wood cladding, etc.),
the following minimum clearances must be complied with:
SAFETY DISTANCE FROM COMBUSTIBLE MATERIALS: SAFETY DISTANCE FROM NON-FLAMMABLE
MATERIALS:
REAR WALL P = 200 mm
SIDE WALL = 200 mm
FLOORING F = 30 mm
FRONT R = 1500 mm
REAR WALL P = 100 mm
SIDE WALL = 100 mm
FLOORING F = 5 mm
FRONT R = 1000 mm
•Besides complying with the minimum clearances set abo e, we also recommend installing heat-resistant fireproof insulating panels
(rock wool, cellular concrete, etc.)

•When it is operational, the sto e can cause a negati e pressure in the room where it is installed. Therefore there should not be in the
same room other naked flame de ices, with the exception only of type c sto es (airtight).
•Make sure that the sto e can draw the necessary quantity of combustion air: this must be from an open space (i.e. a space without
exhaust blowers or pro iding adequate entilation) or directly from outside.
•Do not install the sto e in bedrooms or bathrooms.
•Unpack the sto e: be careful not to damage the product at the time of unpacking.
•Check the sto e's legs and adjust them so that the sto e is stable.
•Place the sto e so that the door and any window openings are not against the walls.
•After connecting the sto e to the combustion air inlet join the coupling de ice to the ent pipe.

INSTALLATION EXAMPLE:
ATTENTION (ONLY EV20 – EV24 MODELS) the measurement between the centre of the
fume outlet and the base of the stove is 170 mm. Check that the T-coupling has appropriate
measurements in order to ensure extraction of the lid for collecting of the ashes.
EXAMPLE OF INCORRECT INSTALLATION:
Exhaust pipes must ne er be fitted pointing downwards or horizontally so that fumes are discharged directly through the external wall.
