- rare - 300 mm,
- front - 800 mm.
- floor –the boiler must be placed on a non-combustible floor.
The manufacturer is not responsible for consequences caused by not
following the instructions.
6.2. Smoke exhaust system
The correct assembly and connection of the flue gas exhaust system is extremely
important for the trouble-free operation of the pellet boiler.
The pellet boiler works constantly with pressure in the flue.
It is forbidden to vent flue gases directly from the pellet boiler through the wall into
the atmosphere.
It is mandatory to install a flue to remove flue gases at a height safe for human health

8
and to be equipped with wind protection.
The flue must be used only by the pellet boiler and no other appliances must be
connected to it.
Flue gases are released from the combustion chamber of the pellet boiler to the
atmosphere through an opening with a diameter of Ø 80 mm, located in its rear part.
If the outlet of the pellet boiler is connected to a metal flue, it must have a vertical part with a
length of not less than 2.5 m, equipped with wind protection device. The pipe system must be
airtight insulated with materials resistant to high temperatures (heat-resistant silicone).
Classic masonry chimneys can be used to vent the smoke. If the pellet boiler is connected
to a brick chimney, it must be well built and plastered (no cracks).
All parts of the flue must be freely accessible for inspection.
In the lower part of the flue there must be an inspection opening, allowing
opening and cleaning.
It is forbidden to install regulating flaps in the smoke outlet (valves that can prevent the
removal of smoke, respectively make it difficult to draft).

Avoid contact with combustible material (such as wooden beams) and in all cases it will
be necessary to isolate them from the metal flue with fireproof materials (see figure 7).
ATTENTION! Do not connect the exhaust gas system of the pellet boiler to a chimney to
which another stove, boiler or aspiration system is already connected.
6.3. Combustion air supply
The air needed to burn the pellets is taken from the room where the pellet boiler is
installed. It is sucked from the smoke fan through a pipe with a diameter of Ø 43 mm.
If there is another heating appliance in the room, the necessary amount of air
must be provided for the proper functioning of all appliances.
6.4. Connecting the pellet boiler to the power supply
The pellet boiler works with a supply voltage of 230 V / 50 Hz and therefore it must
be connected to an electrical supply.
Before connecting the pellet boiler to electricity, make sure that:
•the characteristics of the electrical network correspond to the data or
specification given on the nameplate of the boiler.
•The power cord must be kept away from hot places and must not come into contact
with sharp edges that could injure it.
•When the boiler is installed in the appropriate place, the two-position switch and the
socket must be easily accessible.
•Check that the connection is properly grounded.
•If the boiler is not used for a long time, you must disconnect it from the electrical
network. Place the switch in the OFF position, position (0).
•In case of damage or malfunction, turn off the engine or the switch in the OFF position (0)
and contact an authorized service center.

11. Pellet quality requirements
ATTENTION! The pellet boiler has been tested only with wood pellets with a diameter of 6 –
8 mm, class EN plus A1, acc. EN ISO 17225-2:2014. The manufacturer accepts no
responsibility if you use fuel other than that recommended by the manufacturer.
This pellet boiler is made to use pressed wood (pellets).
There are many products of this type on the market, it is important to choose pellets that
have the lowest ash content and are not too wet (always ask for a pellet test certificate
from the supplier).
The correct functioning of the pellet boiler depends on the type and quality of the
pellets.
When the pellets are of low quality, the boiler must be cleaned frequently.
Benefits of using pellets:
-Allow easy loading.
-Better regulation of fuel quantity.
-The small size of the pellets allows the precise supply of the fuel.
-They allow air supply to achieve optimal combustion efficiency.
The high combustion efficiency is also determined by the low moisture content in
pellets (constantly below 10% compared to 20% to 30% moisture content of sawn wood).
-Pellet bags can be stored in a small area in a dry garage, basement, utility room or
shed.
Pellets should be stored in a dry place that is not too cold. Cold and wet pellets reduce the
thermal power of the fuel and require additional cleaning of the combustion chamber .
Pellets should not be stored near the pellet boiler - at least 2 meters away from it. Do not
crush them.
The manufacturer of the boiler is not responsible for the use of wood pellets with poor
quality, nor for the poor performance of the pellet boiler stove due to such fuel.
12. Information relating to dismantling and destruction of the boiler
Dismantling, disposal and destruction of old, used boilers is the responsibility of the
owner.
The owner of the boiler must comply with all legal regulations of his country and the
European Union regarding safety and environmental protection.
The dismantling and storage of materials from the boiler can be entrusted to a third party
authorized to collect and dispose of these materials.
