1.5 Basic principles and operation
The Interio pellet stove is a special heater intended exclusively for domestic use and
intended only for burning wood pellets of 6 mm diameter and 30 mm length. During
operation, the integrated heat exchanger produces hot water which is delivered to a
central heating system. The integrated pump only switches on when the preset water
temperature in the system (50°C) is reached. For normal operation, it is only necessary
to start the stove and select the desired power value or temperature. By installing the
room thermostat, it is possible to automatically ignite and control the stove. The pellets
automatically fall into the burn pot and then are ignited with an electric heating
cartridge. Depending on the set value of the power, the pellet conveyor automatically
adds the required amount of pellets. The required air supply for combustion into the
combustion chamber is controlled. The resulting heat energy in the combustion
chamber is supplied to the central heating. At the end of the combustion chamber
there is an exhaust fan, which releases the flue gases created in the chimney. Every
day it is recommended to clean the ashes. Every 1-2 months or after consumption of
approx. 500kg Enplus (A1) pellets a cleaning of the flue gas chamber and the pipe
heat exchanger is required. The devices are designed and tested so that they can be
installed in homes and have the necessary approvals. For the combustion air is needed.
For this reason, the combined use of kitchen exhaust systems, and the ventilation in
the same room with a stove is not allowed.

3 SAFETY INSTRUCTIONS
3.1 Proper use
3.1.1 Basic princ iples
The Interio pellet stove has been designed and tested in accordance with the safety
regulations deriving from the EN 14785 directive (and agreed standards). However,
improper use of the stove can ultimately result in the death of users and/or third
parties as well as damages to the stove itself or other property.
3.1.2 Handling wi th the stove
The stove can only be used when it is in proper condition. Use the stove in the manner
described in this manual. Get acquainted with security measures and possible dangers.
Remove all faults and malfunctions that could affect your safety.
3.1.3 Use of the stove
The stove in intended for combustion of wood pellets. Any other use is improper. The
manufacturer will not be held responsible for any damage caused by improper
handling. Proper use implies maintenance of the installed stove, operation and
maintenance conditions prescribed by the manufacturer.
The user can enter or change only those values that are specified in this manual. Any
other parameter value will affect the control program and boiler operation itself, which
can ultimately lead to a Failure of the system or improper operation.
3.1.4 Changes on the stove
It is forbidden to make any changes to the stove and to the equipment supplied with
it. It is forbidden to deactivate the security functions. The manufacturer will not give
any warranty if the user or a third party performs unauthorized intervention on the
stove and equipment that comes with it.
The stove may only be used for the purpose for wich it is produced. The
manufacturer does not accept any responsibility for damage caused to
persons, animals or property resulting from faults in installation, incorrect
regulation and maintenance, and improper use of the boiler.
16
3.2 Pellets that can be used in boilers
The boiler is designed exclusively for burning wood pellets with a
diameter of 6 mm and a length of 10-30 mm.
3.2.1 What is pellet
Pellet is obtained from wood, if it is
possible, from the core of the trunk with
the lowest proportion of bark. The bark
contains the most moisture, dust and
impurities that wood gets during growth,
therefore has a lower caloric value than
the core, and another problem is that it
leaves the sediment when burning. Ideal
wood for pellet production is one that does
not burn too long or too short and creates
a long-lasting glow. Pellets are made from
sawdust waste (typically in a ratio of 20-40% softwood + 60-80% hardwood), in
special machine under high pressure which leads to thickening. It is not allowed to
use any additives or glue during the pellet. production The pellet contains a minimal
amount of moisture and ash, and has a maximum energy value for the type of
wood from which they are produced.
3.2.2 Recommended wood pellets and standars
Pellets quality arises from Standard pellets C1 to EN 303-5: 2012 Table 7; Water
content less than 12% according to DIN 51731 - HP 5, DINplus certification program
and ÖNORM M 7135 - HP 1 or EN PLUS - UNI EN 14961 - 2 (UNI EN ISO 17225-2)
class A1 or A2, 6 mm diameter, length 10-30 mm.
Particular attention should be paid to the quality of wood pellets. Lowgrade pellets can cause malfunction of the stove.
3.2.3 Unallowed fuels
The pellets not consisting the standards mentioned in this manual is not allowed
to burn in a stove. Using a bad quality pellet or any other material can lead to
damaging your stoves's important functions and may result in the termination of
the warranty and associated liability.
17
3.3 Obligatory information
All persons managing the stove must read the manual before starting to
use it and in particular the "Safety instructions".
This applies especially to persons who occasionally work on a stove, e.g.
cleaning and maintaining stoves.
This instruction should always be kept near the installed stove.
Children aged 8 and over, persons with reduced physical, motor or mental capacity,
persons with insufficient experience and training, may use a device of this kind if they
have been provided with supervision or have been given instructions regarding the
safe use of the device and have been presented the dangers arising from it. Children
should not play with such devices. The devices must not be cleaned or maintained by
children without proper supervision.
3.4 Local standards
All local laws must be respected during installation, as well as standards
and norms that are in force in the country where the stove is installed
even though it is not listed in this manual.
During the first installation of the stove or in the event of changes on central heating
system, it is necessary to inform the competent authority in charge for control, and
provide all the necessary permits.
3.5 Safety instructions for the heating room
The heating room must be made according to current regulations, especially regarding
fire protection. Storage of flammable materials, cleaning agents and similar materials
must not be stored in the boiler room
The room where the stove is installed must be frost-resistant.
The stove should not be exposed to colds or freezing temperatures. Extreme low
temperatures can cause malfunction and unexpected behavior of electronic
components.
18
3.6 Fresh air supply
For combustion of pellets and normal work the stove needs fresh air. The room in
which the stove is installed must have an opening for fresh air supply. The
recommended minimum dimension is 30x15 cm.
3.7 Boiler safety devices
The pellet stove is equipped with safety systems which, in the case of
unforeseen situations, serve to stop the power supply and thus stop the boiler
operation.
Microprocessor control: Intervenes directly, turns off the stove until it cools down
and shows an error on the display screen in case of a failure of exhaust fan, malfunction
of the dispenser engine, or failure of the ignition.
Fuse: Quick fuse, protects the stove from large current drops and short circuit inside
the boiler.
Safety limit Thermostat STB: Intervenes with an interruption (turn off) off the
circuit of the auger (pellet feeder) and on the display is displayed AL6.
Vacuum gauge: Intervenes if there is insufficient pressure in the pellet stove (open
door of the stove, clogged chimney) and disconnects the circuit from the auger
(feeder) motor.
19
4 Installation
The commissioning of the system must be carried out by the authorized
personnel by ThermoFLUX d.o.o. or the importer.
The Warranty will not be valid if the stove has not been commissioned by an
authorized repairer.
The first start-up includes the basic operation and maintenance of the stove. The
service technician authorized for the first commissioning must check the functioning of
the stove at least during one complete work cycle. In some countries, it is obligatoy for
first commissioning to be controled and autorizied by chimney sweep or a person
authorized to control.
Risk of material and physical damage due to improper commissioning. If
the first start-up is done by an unprofessional person, damage to the boiler
and the heating system may occur.
4.1 Installation conditions
The minimum distance from the stove must be observed.
A – Minimum distance in front of the door - 100 cm
B – Minimum distance from the left side - 20 cm
C – Minimum distance behind the chimney - 20 cm
D – Minimum distance from the right side - 20 cm
20
4.1.1 Switch off main power supply
Be sure to turn off the main power before any work.
4.1.2 Check mechanical connections
Check that all components are properly connected.
Check that all mechanical components are securely attached.
4.1.3 Check hydraulic connections
Check that the circulation pump and the mixing valve are properly
connected.
Check that the safety equipment is properly connected.
After completing the work, fill the system and wait an hour to control
all the connections.
The pellet stove comes with a built-in expansion tank and can only be connected to a
closed heating system.
4.2 Chimney and flue gas pipes
The chimney should be calculated and constructed in accordance with the EN
13384-1 standard.
The venting of flue gas must be done in accordance with all applicable laws including
those related to dimensions of the chimney and materials used for its production. Flue
gas channel should be made of adequate materials, such as steel tubes, with various
sealing.
In any case, materials that could potentially catch fire, e.g. wooden planks, beams,
cloth, should be adequately protected with non-combustible material. For the sake of
parity of dimensions, chimneys that are round in shape of the inner part should have
an advantage over the rectangular-shaped chimneys.
Too small inner zone can cause irregular flow from the stove to the top which could
lead to poor stove performance and excessive exhaust gas production that discharges
the exhaust gas to the environment. Gas flue pipe should be permanently installed and
it would be good to make safety door which would enable the cleaning of inner parts,
especially the horizontal parts.
Smoke pipe should be installed fixed. It would be good to leave safety gates that could
do the interior cleaning, especially in their horizontal parts.
You should avoid as much as possible horizontal mounting parts. Horizontal parts must
have a slope of at least 3% upwards.
Length of the chimney pipes should be minimal and in any case not more than 3
meters.
ALL PARTS OF THE FLUE GASN PIPE NEED TO BE SECURED AND REPLACEABLE
IN ORDER FOR INTERNAL CLEANING. AVOID MULTIPLE HORIZONTAL
DEVIATION AND ANGLES.
21
The internal cross-section of the exhaust pipes should be smoth and all connections
must be hermetically sealed. Avoid as much horizontal mounting as possible.
Horizontal parts should have a slope of at least 3% upwards. The length of the
horizontal part of the saddle shall be minimum and in any case not more than 2 meters
with the possibility of cleaning and removing the accumulated ash.
The connection to the chimney should be made with a maximum of two exhaust pipes.
For stove operation, a constant negative pressure is required. At reduced power, the
flue gas temperature is low and condensation may occur. It is therefore important that
the chimney is well insulated.
The flue pipes should be made of non-combustible materials that are suitable and
resistant to combustion products and their possible condensation. In any case, the
parts or zones that are flammable, must be properly protected, such as wooden boards
or beams.
FOR SMOKE PIPES, DO NOT USE METAL-FLEXIBLE CABLES. ALL
PARTS OF THE SMOKE PIPE SHOULD BE SAFE AND REMOVABLE TO
CLEAN CLEANING. AVOID HORIZONTAL DEVIATIONS.
22
If the chimney has a too high underpressure (over 20 Pa), the regulation can be
achieved in different ways. One way is to easily open the cleaning door. We
recommend to install the draft regulator.
The pellet stove can not be connected:
To the chimney or the flue pipe to wich another heat source is connected (gas
boiler, pellet boiler, etc.)
Ventilation system
When connecting the pellet stove to the chimney, smoke pipes with a diameter of
80mm and temperature-resistant gakets must be used. It is recommended to install a
T-piece with revision or a knee after the chimney outlet, and a piece of flue pipe of a
length of min. 0.5m and then connect the stove to the chimney. It is not recommended
to connect directly between the stove and the chimney without flue pipes. It is also
not recommended to attach a connection of the flue pipes on the left or right, which
means you do not make knee in the flue pipes in the sides.

25
The pellet stove is supplied with built-in circulation pump, expansion vessel and
safety valve. On the back of the stove is the connection for: power supply 230VAC,
50Hz with main switch, fuse and room thermostat.
5.2.1 Power supply
The stove needs to be connected to a 220V, 50Hz via a separate fuse 6-10A (FAST).
5.2.2 Room thermostat
The user has the possibility to place the room thermostat in one room and does not
need to be in the same room where the pellet stove is. Operation of the stove with an
external thermostat connected to the room thermostat connection may differ if we
have activated the STAND BY function. The connection for the room thermostat comes
from the factory with a bridged connection, wich means that its contacts are closed.
Only room thermostats with potential-free contacts may be connected. It is
recommended that the installation and connection of the room thermostat be carried
out by an authorized service technician.

Water temperature indicator
Regulation on the stoves ''Pelling'' is most important electronic component. It is
consisted of key controling modul set under the cover of the stove and controling unit
with display set on the front side of the stove. With controling unit it is possible to control
functions of the stove and also to check information about present state of the stove.
Due to the possibilty to work in 5 (five) different powers, regulation can satisfy needs
to increase or decrease heating by automatic adjustment of power.
If there is a need to increase power, this is registered by regulation and regulation
gives a signal to increase power by adding more pellet as well as proportional increase
of air flow in the burning basket.
When desired temperature is reached (need for heating energy is satisfied) regulation
is decreasing power ( modulates ), or when room thermostat gives signal that set
temperature is reached, stove then goes into SHUT DOWN mode (if mode STANDBY is ON )

6.2 Principle of stove operation
Principle of the stove operation is very simple.
When button for start is pressed stove goes into IGNITION MODE. START is displayed,
and after that PELLET IGNITION. Usually this phase lasts for 5-15 minutes depending
on type of the stove and pellet quality. At that point dosing system is activated, igniter
and suction fan. Dispenser is making initial dosing of pellet into burning basket. At the
same point igniter starts to ignite pellet and suction fan is on and is making necessary
underpressure needed for combustion. When temperature sensor for flue gasses
detects that temperature in the chimney has reached necessary value, regulation then
changes working mode of the stove into FLAME STABILIZATION.
This phase (FLAME STABILIZATION) lasts for 2-3 min. (depending on the type of the
stove and in this phase igniter goes off. After flame stabilization, stove goes into the
normal working mode and changes power from power 1 to set power. On display is
written WORK. On the right side set power is displayed and in the last

7 Ignition and shutting down of stove
Ignition sequence and description of regulation
Basic function of the regulation is to secure reliable ignition of used fuel, optimal
conditions for combustion and controled sequence for shutting down. Depending on
working power, and complexity of the heating system, parameters are read and
controled differently. Some of the most important ways of working are described with
relevant values.
Before start up following things needs to be checked:
Silo needs to be filled with pellet
Silo doors needs to be closed
Combustion chamber/basket needs to be cleaned
Ash pot needs to be clean
All doors on stove needs to be closed
Stove must be connected to electric source - 220 V, 50 Hz
