6. Components.
Ignition:
Performs ignition of the pellets..
Fume extractor:
Extracts the flue gases from the combustion chamber to the flue pipes and sucks in fresh combustion air by means of vacuum.
Gear motor:
Driven auger screw by means of which the pellets are conveyed from the pellet fuel hopper to the combustion chamber.
Circulation pump:
Provides forced circulation of the fluid in the heating system.
Air vents (manual and automatic):
They are placed in the upper body of the pellet boiler and allow removal of air entered when filling the heating system with
liquid (Figure 3).
Do not forget to connect the heating system to the sewer.
7. Operating mode.
Pellet boiler works with wood pellets. These are cylindrical granules, made of pressed wood whose combustion is controlled by
an electronic control system. The heat from the combustion process is given to the fluid in the heating system.
The pellet fuel hopper, position (A) in Figure 2, is located at the rear of the pellet boiler. Filling of the hopper is through a hatch
located in the rear part of the upper top plate of the pellet boiler. The pellets are transported from the hopper (A) to the
combustion chamber (D) by means of a screw auger (B) driven by a gear motor (C).
The initial ignition of the pellets is carried out by hot air which is sucked in around the ignition (E) in the combustion chamber (D)
through the fume extractor (F). Fume extractor (F) provides combustion air by sucking in from air inlet Ø 50 mm (pos. A in Figure
1) by the room or by outside atmosphere. Upon submission of air from the room there must be provided an influx of outside air.
The flue gases are extracted from the combustion chamber through the fume extractor (F) and are conducted to flue socket Ø 80
mm (pos. D in Figure 1).
Fig.2. Fig.2.1. Fig.3.
The ash from the combustion process is conducted in an ashtray underneath the combustion chamber. The ashtray must be
periodically cleaned by pouring in a metal container or by a vacuum cleaner, but only when the pellet boiler is cold.
Through built-in circulating pump position (K) of Figure 2.1, hot water passes from the integral boiler to the heating system. The
filling and emptying of the heating system is carried out via a built-in shut-off valve position (J) of Fig.2.1. The system pressure is
controlled by pressure gauge built into the front of the top plate.

High efficiency and low emission of the pellet boiler is guaranteed by an electronic control system that manage the amount of
fuel, the flue gases conduction, supplying of combustion air and operation of the circulating pump. The control panel of the
control system is placed in front of the upper panel of the pellet boiler (G) in Figure 2. The control panel can visualize and
manage all stages of the operation of the pellet boiler.
8. Fuel.
Pellet boiler e designed and programmed to burn wood pellets. They have a cylindrical shape and they are made of compressed
by a high-pressure timber, without adhesive and additive materials. The wood pellets are sold in packages weighing 15 kg.,
which facilitates their storage. Better combustion, the wood pellets must be stored in dry and ventilated area. Pellet boiler is
designed, developed, programmed and tested to operate with wood pellets class A1, according to EN plus and BDS EN ISO
17225-2: 2014 with the following parameters:
Maximum diameter: Ø 6 mm
Maximum length: 25 mm
Maximum moisture content: 8 %
Maximum ash content: 0.5%
Minimum calorific value: 4300 ccal/kg
Good quality wood pellets ensure good combustion and lower emissions into the atmosphere.
The use of wood pellets with a lower quality results in a need for more frequent cleaning of the combustion chamber, reducing
heat output and efficiency. They are increasing the fuel consumption sensitively. Inadequate wood pellets can cause blockage of
the auger and to stop the operation of the pellet boiler.
IF PELLET BOILER IS BLOCKED, THE REASON WILL APPEAR ON THE DISPLAY AND IT WILL BE SAVED.
Using wood pellets of poor quality or non-manufacturer recommended as above may compromise the operation of
the pellet boiler and lead warranty void.
Pellet boiler should not be used to burn other types of fuels or materials. Invalid guarantee!
9. Appliance installation.
Trained and competent technicians or companies must perform installing a pellet boiler and heating system! The
manufacturer does not guarantee the operation of the heating system, but only for the pellet boiler. Qualified
technicians should perform all activities in inspection and repair of electrical components. Switch off the pellet boiler
from the grid-circuit before any inspection or repair!
Refer to the regulations valid for the country, which will be used pellet boiler if you do not find the information you are
interested in this instruction manual.
Not recommended installing a pellet boiler in room where there is mounted another heater. If it does, it must be equipped with
a separate air duct.
Compatibility with other devices:
Pellet boiler should not be installed in the same room in which there are absorbers and / or devices that reduce ventilation in the
room.
Checking electrical connections:
Pellet boiler is equipped with a power cable to be connected to a voltage 230V / 50Hz. Changes exceeding by 10% the voltage
can damage the appliance. Grid-circuit must comply with the provisions of the laws and requirements for grounding. According
to the requirements for grid-circuit connection, pellet boiler should be installed so as to ensure free access to the plug and
socket (230V / 50Hz). According to the safety requirements is prohibited the room in which is mounted pellet boiler to an
electrical installation that is located on the floor. Lack of bonding / grounding can cause damage for which the manufacturer is
not responsible.
Positioning:
To have well operating the pellet boiler should be leveled. The floor on which is placed the pellet boiler must be of non-
combustible materials (concrete, terrazzo, marble, terracotta, etc.).
Given the easy servicing and refueling, we recommend the following minimum free distance around the pellet boiler: 1000 mm
at the front, back and sides -500 mm, top -minimum 1000 mm.

Safe distances for fire safety:
When installing a pellet boiler and storage of wood pellets, must be respected the fire safety requirements!
It is recommended that an appropriate place to mount a fire extinguisher.
It is forbidden to store the wood pellets directly to the pellet boiler or a distance of less than 400 mm.
The optimal distance between the pellet boiler and combustible materials is 1000 mm.
Inflammable objects should not be placed on the top plate of the pellet boiler.
If the chimney is connected to the timber wall or other inflammable material, suitable materials such as ceramic wool or similar
must isolate it.
Fresh air opening:
Imperative to ensure submission of fresh air!
The room, in which is mounted pellet boiler must have an opening for fresh air with a cross section of not less than 80 cm² in
order to ensure a sufficient supply of oxygen necessary for combustion. Additionally, it can be delivered outside air through a
steel pipe of Ø 50 mm. In this case, it is possible emergence of condensate. If necessary, the opening for external air can be
protected by a grid. Pipe for outside air has to be mounted on the nearest outer wall to the pellet boiler. Its length should not
exceed 1 m, should not have curves and its location has to prevent clogging. The outer end of the pipe must end with a knee 90˚,
downward or be provided with protection against wind.
Chimneys:
Pellet boiler works constantly with a fume extractor and pressure in the flue pipes and chimney.
It is forbidden flue gases are discharged directly from the pellet boiler through the wall into the atmosphere. Required installed
chimney, which takes flue gases safe for human health altitude over the area of habitation.
It is recommended that the pellet boiler be installed as close as possible to the chimney in order to reduce the number of
connecting flue pipes. Pellet boiler operates at low temperature regime and it is therefore possible occurrence of condensation
in the chimney, which requires more frequent inspection and cleaning.
Chimney should be used only by the pellet boiler and no other appliances have to be connected to it. The flue gases are emitted
from the combustion chamber of the pellet boiler to the atmosphere through a flue socket Ø 80 mm located in the rear. It is
recommended at the beginning of the vertical section of the chimney to mount a T-fitting, with a section for collecting
condensate. Pellet boiler must be connected to the chimney by steel flue pipes, certified according to EN 1856. The flue pipe
system must be hermetically insulated with materials resistant to high temperatures (heat-resistant silicone or grease). Allowed
to have a horizontal section with a length of 2 m. Horizontal section must be a minimum slope of 3% and not more than two
curves at 90°.
If the flue socket of the pellet boiler is connected to a metal chimney, it must have a vertical portion length of not less than 1.5 m
and fitted with a wind protection. Chimney may be located internally or externally. It should be well insulated.
If the pellet boiler is connected to a masonry chimney, it must be intended for appliances for solid fuel. If the chimney has a size
larger from Ø150 mm in diameter, internally along its entire length must be installed tube of stainless steel with a diameter of
Ø150 mm as the free space has to be isolated by masonry. All parts of the chimney should have free access to inspection. At the
bottom of the chimney must be built manhole allowing opening and cleaning at least once a year. On top of the chimney must
be installed a wind protection hat, according to current local regulations.

serve.
It is obligatory installation of filter for incoming water. Failure to comply
with this condition leads to FAILURE WARRANTY of circulation pump!
Circulation pump
The circulation pump is with a high efficiency for water heating systems with an integrated
control of differential pressure.
Control modes:
Variable differential pressure (∆р-v)
Set value of differential pressure H varies within the acceptable range of flow between 1
2Нsand Нs. Factory setting: ∆р-v , 1 2Нmax.
Constant differential pressure (∆р-c)
In this mode of regulation is maintained constant set value of the differential pressure.
Venting function
The pump is vented automatically upon initial startup. If the pump is not vented automatically, select manual mode of venting
"air". The process starts in a few seconds and lasts up to 10 minutes. Select the desired mode of operation of the pump after
completion of venting.
10. Appliance operation.
10.1. Initially ignition.
The installer of the pellet boiler should perform the initial release!
The installer is required:
- to verify that the installation is completed correctly and the expansion vessel meets in size, ensuring safe operation.
- to check the dimensions of the connecting flue pipes and chimney;
- to switch on the power of the pellet boiler and to perform test of the out connectors ;
- to fill up the heating system with liquid through the inlet at pressures to 1.5 bar and make sure that there are no leaks;
- to ensure that all taps between the pellet boiler and heating system are open;
- to bleed the system before starting ( see fig.3);
This operation must be repeated in the first days of use, and when the system is recharged, even partially. The
presence of air in the heating system can aggravate proper operation of the pellet boiler. In order to facilitate venting,
the appliance is equipped with plastic tubing that connects to the air vent.
- to set the pellet boiler according to the type of wood pellets used;
- to carry out emission control of flue gases after installation;
- to make a detailed instruction of the user;
Pellet boiler is coated with high temperature resistant paint, but not against corrosion. In case of accumulation of dust, surfaces
can be cleaned with a soft brush or a dry cloth, but in any case not with a damp cloth or water.
Upon initial ignition do not place any objects on the pellet boiler and do not touch the outer surface to avoid damaging the
coating. The flavor, which is obtained as a result of the drying of the paint, disappears after a few hours. Ventilate the room
where is located the pellet boiler.
If as a result of overheating or due to incorrect operation the color changes, appeared stain rust or damaged part of the
coverage, it is not a problem. You can order spray in the color with your dealer.

11. Instruction manual.
11.1. Wood pellets loading.
The capacity of the pellet fuel hopper is 50 kg. The opening for loading the hopper is with dimensions 150 x 320 mm.
Pellet boiler is equipped with an electronic control system that monitors the remaining amount of wood pellets in the hopper in
kg. The check is carried out continuously until the pellet boiler works.
For proper appliance operation, it is important the person who has installed the unit to comply with the following procedure in
the initial ignition. Have to load and use 15 kg. of wood pellets. This will allow loading of the supply system. Load a new supply of
15 kg wood pellets..
11.2. Wood pellet refueling.
When the pellet fuel hopper is completely empty, it means that the screw auger is also empty. Before re-ignite the pellet boiler
is necessary to load it with wood pellets. Follow these steps:
•Load the pellet hopper with pellets.
•From main menu select „manual mode” . Choose „Feed screw” and start with button
When the feed screw is full with pressing the same button the filling stops.
•Press and hold button „Start/Stop” for more than 3 sec –starts the automatic working process.
It’s possible sometimes few pallets to remain in the fuel hopper. It’s necessary to clean it once a month, to remove any dust
particles or other materials.
12. Maintenance.
Disconnect the power supply of the pellet boiler before performing any activity!
Vacuum the combustion chamber before each ignition. If combustion is stopped, do not start the pellet boiler again until you
have emptied and cleaned the combustion chamber.
The wood pellets, which are subtracted from the combustion chamber, should not be put back in the pellet
fuel hopper!

To operate properly, the pellet boiler must be regularly serviced.
12.1. Daily cleaning.
For better heat transfer and reduce fuel consumption, its need daily cleaning of the soot in flue channels. While pellet boiler
works, open the top door and by energetic movements move up / down of the cleaning elements through the handle (Figure 6).
Suffice cleaning once a day. Durring the manipulation, wear protective gloves.
Fig.6. Fig.7. Fig.8. Fig.9.
Activities to be carried out during the cleaning, when the pellet boiler is cold.
Clean pellet boiler with a vacuum cleaner only when it is completely cold. The procedure takes a few minutes.
- Open the lower door and throw away the ashes from the ashtray (Figure 7);
- Open the middle door and remove the combustion chamber or use spatula to scrape off any scales that clog the holes (Figure
8);
- Vacuum the combustion chamber and all contact edges;
- Clean the glass when it is cold. If necessary, use appropriate detergent.
Never vacuum hot coals, because this may damage it!
12.2. Weekly cleaning.
- Empty pellet fuel hopper and clean with a vacuum cleaner if the pellet boiler was not used for an extended period.
- Clean ignition (figure 9).
12.3. Cleaning ash from the flue channels.
Vigorously shake the cleaning elements by the handle (Figure 6) when the pellet boiler is not working and it is cold. Open the left
and right manholes (Figure 10 and 11) and clean with a vacuum cleaner the accumulated deposits.
Fig.10. Fig.11.
The amount of soot depends on the quality of fuel used. If this cleaning procedure is not performed, pellet boiler may jam. Upon
completion of the cleaning, make sure that all manholes are properly closed.
12.4. Seasonal maintenance (performed by the installer).
Disconnect the power supply of the pellet boiler before performing any activity!
- Clean pellet boiler internally and externally;
- Carefully clean the pipes of the integral boiler;
- Carefully clean and remove dirt and ashes from the combustion chamber and related divisions;
