Fuel properties
Use of liquid or any other solid fuel other than wood pellets is strictly forbidden.
The main characteristic of this stove is that it burns natural fuel (wood pellets), which is ecologically produced from
waste in the wood-processing industry (chips/sawdust). Having been properlycleaned and dried, the chips and the sawdust
which are produced in the wood-processing processes, are compressed under extremely high pressure to produce small
cylinders of pure wood: pellets. Each tiny cylinder can vary in length and thickness, from 1 to 3 cm in length and 6 to 8 mm
in diameter.
Wood pellets are primarily distinctive by a low moisturecontent (below 12%) and high density (=600 kg/m3), as well
as with their uniformity and compactness, which gives thistype of fuel characteristics of high caloric value (DTV 4100-5000
kcal/kg).

Wood pellets that are used as fuel for this stove must have excellent quality properties such as the ones prescribed by the
standards DIN 51731, ONORM M 7135, and EN plus A1, for which numerous basic items are given below.
CAUTION: To achieve the best possible level ofoperation of the stove, we recommend the use of the wood pellets that
are verified by the accredited body. Use of pellet typesother than those defined by the manufacturer maycause defect of the
stove and annul the warranty.
Storage and handling of the wood pallets are importanttasks that must be performed carefully.
-The fuel must be stored at a dry and warm place.
-The pellets must be handled in such a way as to prevent theirexcessive crushing and becoming fine powder.
Adherence to these two simple rules shall enable better efficiency of the combustion and even preserve the proper
operation of the movable mechanical parts of thedevice.
CAUTION: If the device is not used for a sufficient period of time (more than fifteen days), all remaining pellets should
be removed from the tank in order to prevent their excessive moisture since it may lead to deterioration of the product.

INSTALLATION
To install the product successfully and avoid the occurrenceof failures, we give you below a number of simple advice for
assembling, in line with applicable relevant regulations. You must adhere to all local and national laws and the European
standards when installing, using and maintaining the device.
Placing the device
Our product produces heat by entering air necessary for the combustion process directly from the environment that is to
be heated.
For this reason, as well as for the reason of safety of users of the stove, the device has always to be installed within an
adequately ventilated environment to ensure a constant flow of air for combustion. Therefore, it is necessary to install
openings for the air intakethat is connected to the outside air (as shown in the Figure 2.1).
The openings for the air intake must have the following properties:
1. They must have internal cross-section not smaller than 80 cm2;
2. They must be placed at the approximate floor height;
3. They must be appropriately protected with a wire mesh ora grate in order not to decrease the minimal condition of the
radius for the air flow;
4. They must be installed so as not to be blockedin any way
5. Proper flow of fresh air can also be provided by using an opening to the adjacent room, if it is a room equipped with
direct ventilation and if it does not present a risk of fire, such as a warehouse, garage, or storage area.
You are recommended to avoid installation of the heatingdevice in rooms where there are devices that cannot operate in
a closed mode relative to the environment or in rooms where there are devices that can decrease the pressure inthe room
itself relative to the outside environment, since it can lead to problems of poor intake of air for our product.
CAUTION: It is forbidden to place the stove in a common chimney..
During the check of the system compatibility, you are recommended to verify that the supporting area (the floor) has the
adequate weight capacity (kg) to withstand the weight of the product. If this is not so, you are recommended to undertake
adequate safety measures (e,g.use of a panel for the weight distribution).
CAUTION: Place the external parts of the stove at a distance from any fuel or flammable material: 30 cm from the rear,
30from the lateral and 80 cm from the front side. Ifkeeping of theabove distances is not possible, please provide
corresponding thermal protection.
Figure 2.1: Example of required air intake openings
CAUTION: Never allow the flammable materials to get close to each other, or even get intocontact with theexternal surfaces of
the combustion chamber, since they may reach extremely high temperatures while the product is operational.
CAUTION: If the floor is made of flammable material (e.g. hard wood), you are recommended toprotect it by placing a layer
of non-combustible material below and around the stove.
During the installation phase, pay attention that the electrical cable is accessible when the installation is completed.
⚠CAUTION: The electrical cable must be equipped witha corresponding earthing terminal.

6
CAUTION: Avoid touching the electrical cableswith wet hands.
Figure 2.2: Maximum safety distance of the combustionmaterial [cm]
CAUTION: After determining the place where you will place the stove, it is possible to adjust the legs on the side of the
stove to achieve the desired height.. Twopersons are needed for the lateral movement of the stove. After you adjust the legs,
place down the stove very carefully.
Characteristics of the flue pipe
Main properties of the flue pipe are listed below:
-Inspection opening (I);
-Maximum height of the pipe directly connected to the opening of the flue exit on the stove must be 2 to 3 m;
-If you need a horizontal segment, please do not exceed 1.5 m in length and a slope of 3 to 5% in order to facilitate the
exit of smoke;
-Use a wind and water resistant end piece on the flue to minimize the change in draft value.
Use the end part that is resistant to wind and waterto prevent change of the state of somewhat larger pressure
of the flue pipe itself (do not place a horizontal part at theend of the flue pipe);
The state of somewhat larger pressure of the flue pipeis needed to make easier flow of the smoke from the combustion
chamber towardsthe outside environment.
Have in mind that any removal of excessive heat ismade by the electrical controlpart (modulation, extinguishing, etc.).
-The exhaust channel must be made of materials that are resistant to the products of combustion and to moisture (the
check shall enable removal of any kind of moisture);
-The channels should be manufactured in such a way as toprevent any smoke leakage;
-The channel should be insulated, especiallythe external part that is exposed to weatherconditions.
Avoid using completely horizontal segments.
Figure 2.3: Exhaust channel
The room where the heating system is to be installedshould not have hoods since they may reduce the pressureof the
environment.
Closing of air openings is strictly forbidden.
The exhaust channel must be cleaned at least once ayear; we recommend thorough cleaning of both the exhaust
channel and its connections.
After a period of inactivity and before the start,check that there is no congestion.
CAUTION: The exhaust channel must be constructed in line with the provisions of applicableregulations.
CAUTION: Check with the appropriate tool whether the chimney has a minimum (draft) of 10 Pa.
One of the solutions that may be applied includes installation of the wood pellet stove near the external wall ofthe house
tolet the exhaust gases escape directly to the outside environment. (Figure 2.4). Some notes highlighted by the standard for

this type of system configuration are given below:
-Always ensure that there is an inspection opening (I) to allow for regular cleaning procedures as well as the removal of
moisture that may form.
-The chimney pot (T) must be made so as to be resistant towind and water;
-Pay attention that the chimney is properly insulated in the part that passes through the wall.
If the flue is located entirely outside, it must be made of double wall stainless steel to ensure greater resistance to
atmospheric conditions, as well as the correct temperature of the exhaust gases themselves.
Figure 2.4: Smoke exhaust toward the external wall
Flue gases of a stove may be removed via a traditional, already constructed chimney (Figure 2.5), if it meets the applicable
standards. The main properties of a good chimney (Т) are concisely listed below:
-Proper insulation, first of the external part that is exposed to atmospheric conditions;
-Constant internal diameter (there must be no segments with a smaller diameter);
-It must be made of material that is resistant to high temperatures, to the effects of the combustion product and to
corrosion effect of the moisture that may be formed;
-Mainly vertical position, with no deviations ofvertical angles exceeding 45°.
We recommend that the base of the chimney is equippedwith a chamber for collecting of solid particles or moisture(R).
The chamber must be accessible via hermetical door (I).
Figure 2.5: Smoke exhaust towards the roof viatraditional chimney
It is recommended to follow the guidelines established by the standards UNI 9615 and UNI 9731 in relation to the size
and diameter of the chimney (T). However, never use an exhaust duct with an internal diameter of less than 100 mm.
In the case of exhaust ducts with a larger diameter, a steel pipe (A) must be placed inside the brick or mortar of the
chimney (C), as shown in Figure 2.6.
