INSTRUCTIONS FOR CONNECTING, OPERATION, AND MAINTENANCE OF THE STOVE
Heating devices (in this manual they are called “stoves") by TERMAL INT LTD (in this manual
titled producer) are assembled and tested in accordance with the safety and applicable measures,
and regulations of the European Community.
This manual is intended for users of the boilers, contractors who install the boilers, operators and
workers for boiler maintenance that is shown on the front page of the manual.
If you do not understand something in this manual, please contact our professional services or an
authorized Termal int service center. In doing so, always specify the number of the chapter where
there is some ambiguity.
Printing, translation and reproduction, even in part, of this manuLal is subject to licensing by Termal int
ltd, which means that producer, must approve these actions. Technical information, figures, and
specifications in this manual must not be given to a third party.
WARNING:
IMPORTANT: Connecting the appliance to the electrical installation must be carried out by
qualified and authorized persons in accordance with applicable regulations.
This appliance is not intended for use by persons (including children) with reduced physical,
motor, and mental capabilities, or to persons with a limited knowledge and experience in the
absence of the person responsible for their safety or care.
Boiler is not a toy; Children without supervision cannot be allowed near this appliance.
DOUBLE COMBUSTION SYSTEM
The flame obtained by proper combustion of the pellet in the stove emits the same amount of carbon
dioxide (CO2), which would be freed as a result of the natural decay of wood.
The amount of carbon dioxide (CO2) obtained through combustion or decomposition of plant mass
corresponds to the amount of carbon dioxide (CO2) which the plant mass is able to obtain from the
environment and to transform it into air and carbon of the plants during its entire lifetime.
The use of non-renewable fossil fuels (coal, oil, gas), contrary to what happens with the wood, releases
into the atmosphere huge amounts of carbon dioxide (CO2), that have been gathering up for millions of
years, creating a greenhouse effect. The use of wood as fuel is therefore perfectly balanced with the
environment, because the wood as a renewable fuel is in ecological harmony with nature.
Using the principle of clean combustion, we fully achieve these objectives, and so producer has directed
its development and all activities towards fulfilling this goal.
What do we consider clean combustion and how does it work?
Controlling and adjusting the primary air and injecting the secondary air causes secondary combustion, or
the so-called post-combustion, which provides a secondary flame that is by its nature lighter and stronger
than the primary flame. The addition of new oxygen (inserted through the air) allows further combustion of
gases that are not completely burned. This significantly increases the thermal efficiency and reduces
harmful emissions of carbon monoxide (CO), because the incomplete combustion is minimized. These
are the basic characteristics of these stoves and other products of this produce.

2. THE PURPOSE OF THIS MANUAL
The purpose of the instructions is to enable the user to take all the necessary measures in order to
ensure safe and proper use of the stove.
2.1 UPDATES
This manual reflects a work of art at the moment when the boiler was placed on the market. Therefore,
producer does not take into account the boilers that are already on the market with the appropriate
technical documentation and considers them as defective or inadequate after any kind of modification,
adaptation or application of new technologies to newly produced machines.
The contents of this manual should be carefully read and studied. It is necessary to strictly follow all the
instructions given in this manual. All information contained in this manual is necessary for proper
connection, use, and maintenance of your stove.
Therefore, this manual has to be carefully stored for the necessary instructions in the event of any
problems or concerns.
If the stove is given or sold to another person, the new owner must also be given this instructions manual.
If you have lost your manual, you can request a new copy from the manufacturer, authorised distributor or
service person.
3. RESPONSOBILITIES OF THE MANUFACTURER
In issuing these instructions, producer accepts no civil or legal liability, direct or indirect, due to:
•Accidents caused by not respecting the standards and specifications given in this manual,
•Accidents caused by improper handling or use of the stove by the user,
•Accidents resulting from modifications and repairs, which were not approved by producer,
•Poor maintenance,
•Unforeseen events,
•Accidents resulting from the use of spare parts that were not original or not intended for
these models of stoves.
Responsibility for connecting is fully assumed by the installer - contractor.
3.1 GENERAL TERMS OF USE
The user of the appliance must have the following basic characteristics:
•be an adult and responsible person,
•have a specific technical knowledge that is needed for routine maintenance of electrical and
mechanical components of the stove.
CHILDREN ARE NOT allowed near the boiler without adult supervision.BOILER is not a toy.

9
3.2 TRANSPORTING AND MOVING THE BOILER - HANDLING
When moving the boiler, it is necessary to be careful and not allow the boiler to tilt forward. This is
because the brunt of the stove is forward.
During transportation of the stove, which has to be completely safe, make sure that the forklift has the
load that is greater than the weight of the stove that it is supposed to lift. Avoid twitching and jerking
movements.
ALL PACKAGING MATERIAL SHOULD BE REMOVED SO THAT IT IS OUT OF REACH OF
CHILDREN, BECAUSE THE MATERIALS THAT ARE INSIDE CAN LEAD TO CHILDREN
SUFFOCATING. THESE INCLUDE PLASTIC BAGS, FILM, POLYSTYRENE, ETC.
3.3 RESPONSOBILITIES OF THE INSTALLER
Installer's responsibility is to do all the tests of the flue pipeline, air supply, and all the things that are
necessary for connecting (installing) your stove.
Installer's responsibility is to harmonize the boiler installation to local regulations which apply where the
boiler is connected (installed).
The use of the stove must be in accordance with the instructions for use and maintenance, as well as
with all the security standards that are given by the local regulations that apply where the boiler is
connected (installed).
The installer has to check:
•the type of boiler to be connected,
•whether the room corresponds to the boiler where the boiler will be installed, which is
expressed as the minimum size required for installation, set forth by the manufacturer of the
boiler,
•heat generator
•manufacturer's instructions regarding the requirements of smoke removal systems (ducts and
pipes for smoke exhaust),
•inner cross section of the chimney, the material out of which the chimney is made, uniform
cross section,
•that there are no disturbances and obstacles in the chimney,
•height and vertical extension of the chimney,
•altitude at the place of connecting the boiler,
•the existence and suitability of the protective cover for the chimney that is resistant to the
wind,
•the possibility of securing the external air supply and the size of the necessary openings,
•simultaneous use of boiler that needs to be connected with other equipment that already
exists at that place.
If the results of all checks are positive, then we can proceed with connecting the stove. Make sure you
follow the instructions of the manufacturer of the stove, as well as the standards for fire protection and the
safety standards provided.
When you are finished connecting, the boiler has to be turned on in trial mode for at least 30 minutes to
test if the boiler is working properly.
When the installation and important details are completed, the installer must provide the client the
following:
•Instructions for use and maintenance issued by the manufacturer of the boiler (if such instructions
are not provided with the stove),
•The documentation necessary to comply with the existing standards.

10
4.INSTALATION – BOILER INSTALLATION
Responsibility for the work carried out at the place of connection is entirely on the user.
Before one turns the boiler on, the installer must meet all legal standards of safety, as well as the
following requirements:
•to check that setting up that boiler complies with local, national, and European regulations,
•that the location of setting up the boiler meets the requirements set forth in this manual,
•to set up the flue pipes,
•that air intake matches the type of the installed boiler,
•that the electrical connections are not set up using temporary and/or not insulated electrical cables,
•to evaluate the effectiveness of grounding electrical systems,
•to always use personal protective equipment and all means of protection that are prescribed by
local regulations,
•to always provide sufficient service space required for any maintenance and repair of boiler
4.1 INSTALLING THE BOILER
We recommend you to unpack the boiler only when the boiler is set up in the position where it will be
connected.
If the surrounding walls and/or floors are made of materials that are not resistant to heat, then one
should use adequate protection using the insulating material that does not burn.
Always make sure that you leave a safe distance (about cc 35/45 cm) between the boiler and furniture,
home appliances, etc. To protect the floor if it is made of combustible materials, we suggest you put a
metal plate under the stove on the floor with the thickness of 3-4 mm that will stretch at least 30 cm in
front of the boiler.
The boiler must be at least 25 cm away from the surrounding walls. Always leave at least 15 cm
between the rear side of the stove and the wall to allow for proper air circulation, or for the air to flow
properly in that area.
If the stove is installed in a boiler house with a existing devices for sucking out air or if it is placed in the
room with appliances that use solid fuel (such as a wood burning stove), always make sure that the
amount of inlet air in the room is sufficient to ensure safe operation of the boiler.
If a smoke channel goes through the ceiling, it should be properly thermally insulated using the protection
out of insulating materials that does not burn. When the boiler is set up into place, it should be levelled.
DANGER!
The exhaust gas Armour must not be connected to:
•the smoke pipe used by another heat generator (boilers, furnaces, fireplaces, stoves, etc.),
•the air drawing system (grilles, ventilation openings, etc), even if the system is inserted into the
drain pipe.
DANGER!
Postavljanje ventila na cijevi za protok (draft) zraka (ventili sprečavaju protok zraka i onemogućavaju
draft) je zabranjeno.

11
ATTENTION!
If the ejection path of smoke creates such a bad draft, of a bad flow of air (many curves, improper
completion of the ejection of smoke, constriction, etc.) discharge of smoke can be bad, or in a situation
like this smoke discharging is not as good as it could be.
The smoke ejection system from the boiler operates under negative pressure in the stove chamber and
with mild pressure from the smoke drain pipe. It is very important that the smoke extraction system is
hermetically closed (sealed). This requires the use of a smooth tube on the inside. First of all you must
carefully study the plan and structure of the room when the smoke extraction pipe is set up through the
walls and roof, so that the installation of pipes is performed properly in accordance with the standards of
fire protection.
You should first ensure that the room where the boiler is located has enough air for combustion. It is
advisable to periodically perform check so as to ensure that the combustion air comes right up to the
combustion chamber. The stove operates at 220 V ~ 50 Hz. Make sure that the electrical cord is not
underneath the boiler, to be away from the boiler, to be away from hot spots, and not to touch any sharp
edges that it could penetrate. If the boiler is electrically overloaded, this can lead to shortening of the
lifetime of the electronics of the boiler.
Never turn off the power supply by pulling the plug when there is a burning flame in the boiler.
This could jeopardize the proper functioning of the boiler.
4.2 THE SMOKE EXHAUST SYSTEM
The smoke exhaust must be carried out in accordance with existing standards. Exhaust gas tube should
be well sealed (see Figures 2-9).
For smoke exhaustion, one can also use classic brick chimneys while flues can also be made of pipes
that need to be well insulated (double wall) and sealed, to avoid creating condensation in them.
The drain tube absolutely must not be connected to other systems of any kind, such as the systems
where the smoke is removed from the combustion chamber, exhaust grilles or air distribution system, etc.
Also, the smoke exhaust must not be set up in enclosed or semi-enclosed areas such as garages, narrow
corridors, underground passages, or at any other similar places. When the boiler is connected to the
exhaust gas pipeline, it is necessary to bring professional chimney sweep to verify that the chimney does
not even have the tiniest cracks or fissures. If in the exhaust gas chimney there are such cracks, the pipe
for smoke exhaustion must be wrapped in insulation for proper functioning.
For this purpose, the tubes that can be used are solid and made of painted steel (minimum thickness 1.5
mm) or from stainless steel (minimum thickness 0.5 mm).
The smoke extraction system (chimney) built out of metal pipes must have grounding in accordance with
existing standards and regulations. Grounding is required by law.
The grounding connection must be separated from the grounding for the boiler.
The smoke exhaustion pipe must be done according to the standards in terms of dimensions
and materials used for its construction (Table 1).

12
A) The top of the chimney is resistant to wind
B) Chimney dimensions are not limited; important is that chimney does not have more then 15 Pa
draft
C) Gasket /Sealed
D) Inspection hole - for control
Flue pipes that are in poor shape, or are made out of inappropriate materials (asbestos cement,
galvanized sheet, etc. with rough or porous surfaces) are inadequate and jeopardize the proper
functioning of the boiler.
The smoke can be drained through a classic smoke pipe (see next Figure), provided that it meets the
following requirements:
- Check the maintenance of the drain flue pipes or chimneys. If the smoke drain pipe is old it should be
replaced with a new one. If the chimney is damaged it is good to repair it or rebuild it by inserting a steel
pipe that is properly insulated with mineral wool.
- The smoke can be discharged directly into the smoke pipe (chimney) only if it has a minimum draft of 5
Pa, and not bigger then allowed limit (15 Pa), and if there is a cover for checking and cleaning.
- If the chimney draft is less then minimal needed (5 Pa), or if draft is bigger then maximum
allowed (15 Pa), possible increased regulation of draft (its decrease) in the chimney can be regulated ba
following ways:
1. If in the bottom of the chimney there is an opening for cleaning, on opening can be installed draft
regulator.
2. Insert a steel pipe in the chimney with a diameter of 12cm or more, if there is a possibility for such
reparation of the chimney.
3. Inspection of chimney by adequate chimney service and proposal solutions to problems from their part
4. By adjusting certain parameters in the stove. This adjustment must be done only by an authorized
service of Termal int.
- Make sure that the connection to home chimney is properly sealed.
- Avoid contact with material that burns easily (such as wooden beams), and in all cases they should be
isolated with anti-fire material.
A) Mineral wool
B) Steel pipes
C) A peripheral wall
The stove is designed to be connected to the chimney flue pipes with a diameter of 80mm. If you are not
using a standard chimney, but you have a new chimney, or you are modifying the existing one, use
insulated stainless pipes (double wall) with a diameter given in Table 1. Flexible pipes are not permitted.

When using the connecting pipe between the boiler and the flue drain hole, be sure to use a connector
(as shown in Figure 4a), with the clean-out cover (cap) next to the boiler. Applying this connector must
enable the collection of ash, which is produced inside the tube, and the smoke drain pipe must
occasionally be cleaned without having to remove the tube. The smoke is under mild pressure and
therefore it is required to check the cover (cap) for cleaning the exhaust gas system that is perfectly
sealed and it remains so after each cleaning. Make sure to perform the same sequence for assembly and
check the condition of the seals.
Install the flue pipes pursuant to Figure 9.
It is strictly recommended to avoid the use of horizontal extensions, and if necessary, make sure that the
pipe is not bent but that it has the slope of at least 5%. The horizontal part of the drain flue pipes must not
in any case exceed the length of 3 m.
It is not recommended to connect the smoke exhaust directly to the boiler with a horizontal part longer
than 1 m. See Figures 4 - 9. After the connector (figure 4a) it is necessary to set up a vertical extension of
Ø 80mm in length for at least 1-1.5 m, and only after that to move to the horizontal extension of Ø 80mm
and a vertical extension of Ø 80 or Ø 120mm, depending on the height of the flue pipe (chimney) as
shown in Table 1.
When connecting the boiler to the chimney using fittings, one must install a knee with a hole for cleaning
(Figure 4a). Using the knee with an opening for cleaning allows for regular cleaning, without the need to
dismantle the pipes. Drain gases in the chimney connector are under mild pressure so it is necessary to
check that the cover for cleaning the ashes is completely sealed and to seal it after each cleaning. Please
make sure everything is properly returned to its place, and check the condition of the seals.

14
Figure 4a. Cleaning elements
Ideal vacuum primarily depends on the absence of barriers such as narrowing and/or corner connectors.
It is recommended that the knees are 30°, 45 °, and 90 °. Knee at 90 ° shall be three-fold (Figure 4b).
In any case, it is necessary to ensure that the initial part of the vertical flue pipe has the length of at least
1.5 m. Only in this way can you achieve the proper removal of flue gases.
Figure 4b.
In Figure 5, left, we show how a complete (top) is supposed to look like when you have two chimneys
next to each other, and in Figure 5, right, how not to do the end part.

4.3 3 INSULATION AND THE DIAMETER OF THE OPENING (HOLE) ON THE ROOF (OR IN THE
WALL)
Once you determine the position of the boiler, it is necessary to make a hole through which a smoke pipe
must pass. This varies depending on the type of installation, diameter of the exhaust gas pipe (see Table
1) and the type of wall or roof for the tube to pass. See Table 2. Insulation needs to be made out of
mineral wool with a nominal density greater than 80 kg/m2.

Above all it is necessary to provide the PERFECT AIRFLOW (draft) in pipes for smoke exhaustion that
has to be free, without any obstacles, such as different narrowing or corners. All displacements of the axis
must have a tilted orbit with a maximum angle of 45 degrees from the vertical, while 30 degrees is the
best solution. This displacement would be best done near the top of the chimney resistant to the wind.
According to the regulations (the top of the chimney resistant to wind, distance, and placement of
the stove) the distances shown in Table 3 must be met:

However, it is required to provide an initial vertical extension of 1,5 m (minimum) in order to
provide proper discharge of smoke.

4.4 COMMBUSTION AIR SUPPLY
The air required for combustion, which is taken from the environment, must be supplied by a single
ventilation grill mounted on the outer wall of the room. This will ensure better combustion and thus lower
consumption of pellets. It is not recommended to have outside air drawn directly from the tube, as it will
reduce the efficiency of combustion. A ventilation shaft must always be equipped with one ventilation
grille on the outer side as protection from rain, wind, and insects.
This hole must be made on the outer wall of the room where the boiler is located.
The supply of combustion air from the garage, a warehouse for combustible materials, or from a
room where there are risks of fire is prohibited.
The opening of the outer supply of combustion air must not be connected by pipes.
Opening for fresh air supply necessary for combustion, must not be connected by hoses
(limitation is hose fi 75mm, length 10 m, and maximaum 5 knees 900used.
If the room has some other devices for heating, the supply of combustion air must ensure the
amount of air that is required for proper operation of the all devices.
Figure 10. Minimum gaps for setting up ventilation grilles
For proper and safe placement of ventilation grilles see data given in Table 4. These are the minimum
distances from each airspace or smoke extraction. This value can change the configuration of the air
pressure. It should correspond to the ordering to secure that the open window draws outside air,
depriving the boiler of it.

4.5 CONNECTING THE POWER
These stoves are connected to electricity. Our stoves have electrical cables that are suitable for medium
temperature. If you need to replace the power cord (if it is damaged, for example) then consult with our
authorized technical staff. Before you plug in the electric stove note the following:
- That the characteristics of electrical systems correspond to the information that is specified in the data
on the identification plate on the boiler.
- If the smoke extraction system is metal, it must have a grounding terminal in accordance with the
existing standards and legislation. Grounding is the law.
- The electrical cable must not at any time reach a temperature that is 800C above the ambient
temperature. When the stove is installed and placed in its spot, a bipolar switch or socket must be easily
accessible.
- If the stove is not used for a long time, unplug it or switch to the switch off (0) position.
In the event of failure or malfunction, turn off the stove right away or switch to a switch off (0) position
and contact an authorized service center.
5. IMPORTANT INSTRUCTIONS
THE FOLLOWING INSTRUCTIONS ARE REQUIRED FOR THE SAFETY OF PEOPLE, ANIMALS, AND
PROPERTY.
We wish to inform the installer of the boiler on some of the general guidelines which must be followed for
proper installation and for proper boiler mounting. These standards are required, but not complete. For
further and more detailed information one needs to read the rest of this instructions manual.
•Plug the stove into an outlet that is grounded. Figure 12,
•The switch on the rear of the stove is set to position 1.
•Do not allow children or pets to be near the stove.
•Use pellets only, not other fuel.
•Notify all users about the potential risks and dangers and teach them how to handle the
appliance.
•If the biler is placed on a wooden floor, then it is recommended to isolate the pedestal on which it
stands.

The stove operates with a combustion chamber, which is in the negative pressure. Therefore, make sure
that the smoke is well thermally insulated.
When the stove is turned on for the first time then, due to the stabilization process a small amount
of paint (not harmful to health) that covers the stove vaporizes. It is therefore necessary to air the
room so that it is cleared from the fumes.

6. WARNING SAFETY MEASURES FOR STAFF
MAINTENANCE
The contractors who work in maintenance, in addition to following all safety measures, must:
•Always use safety equipment and personal protective equipment,
•Turn off the power supply before they start working,
•Always use the appropriate tools,
•Before they begin any work on the boiler they need to keep in mind that it should be cold and that
the ashes should be cold as well. They need to make sure the handles are cold as well.
•NEVER TURN THE BOILER ON if there is just one of the safety devices that is defective,
improperly set up or it does not work at all.
•Do not make modifications of any kind, for any reason, other than those permitted and explained
by the manufacturer himself.
•Always use original spare parts. Never wait until the components wear out before you replace
them.
•Replacing the worn parts or the components of the boiler before they stop working contributes to
the prevention of damage caused by accidents due to sudden failure, or breaking of the
components, which can lead to serious consequences for people and/or property located around
the boiler.
•Clean the firebox before lighting the boiler.
•Make sure there is no condensation. If condensation occurs it shows that there is water from the
cooling smoke.
We recommend you find the possible causes to be able to establish a regular and correct operation of the
boiler.
