2 Safety notes
2.1 Proper use
2.1.1 Basic principles
Minitherm stove was built in accordance with safety regulations. However, its use can
result in the injury or death of the user and/or third part and in impairments to the
stove itself or to other material goods.
2.1.2 Using the stove
Use the stove only when it is in perfect condition. Use it properly, as described in this
manual. Stay aware of the safety and of the dangers involved. Have any faults which
can impair safety immediately fixed.
The stove was designed to burn wood pellet and wood. The manufacturer will accept
no responsibility for any damage resulting from improper use. Proper use includes
maintaining the installation, operation and maintenance specified by the
manufacturer. The user may only enter or change the operating values specified in
this manual. Any other entries will affect the stove's control program and operation,
which can lead to a malfunction.
2.1.3 Permissible fuel for the Minitherm - stoves
Only wood pellets and wood are permissible as fuel for the stove. Wood pellets are
pressed into a cylindrical shape. They consist of untreated sawdust from the wood
processing industry as well as unprocessed forestry waste. They have a standardized
diameter and length and very low air content.
2.1.4 Recommended wood pellets
Thermo FLUX d.o.o. recommends wood pellets with a diameter of 6 mm and a
length of 10 - 30 mm.
Other requirements on the fuel result from either standard O-Norm M 7135,

2.3 Other risks of the side effects
Despite the precautions taken there are also certain risks of side effects:
DANGER OF CARBON MONOXIDE.
If the stove is running during cleaning time may occur
transmission of CO through the open door. Do not open the
door longer than necessary.
2.4 Duty to inform
Reading the manual
Everyone who works on the stove must have read the Use and maintenance manual
before starting work and, in particular, have read the second chapter „Safety notes“.
This holds especially true for persons who only occasionally work on the stove e.g.
when cleaning or maintaining the stove. This manual must be kept ready to hand at
the stove's installation location.
Pay particular attention to the applicable local standards and guidelines.
2.5 Safety devices
Stove is equiped with safety devices that in case of unexpected situations
stop the power supply and thereby stop the operation stove.
Stove electronic regulation: operates directly and stops the operation of the stove
until it cools down.
* In case of the suction fan failure, failure of the motor for auger (doser), black out
(if the blackout was longer than 10 seconds), an unsuccessful firing.
Fuse F 4 A 250V : Fast fuse , protects the stove from large voltage changes of
electricity and short circuits inside the stove.
Safety thermo switch (STB) : intervenes by breaking the circuit in the stove
(automatically stops motor of the auger and exhaust gasses fan) if the stove
temperature reaches the limit of 95 °C.

3Installation and commissioning of
the stove
Commissioning system in the operation is performed by personnel
authorized by ThermoFLUX Ltd or autorized seller.
Commissioning includes referral to operation with the basic operations and
maintenance of the stove. Authorized service for the first start, must control the
functioning of the stove at least during one full operating cycle.
Danger from material and body due to improper
commissioning. If the commisioning is performed by
unautorished personel, it may cause damage to the stove
and heating system.
3.1 Conditions
The following conditions must be fulfilled before the system is put into
operation.
Turn OFF electrical power.
Check mechanical connections
Check that all components are properly connected
Check that all mechanical components are connected.
Check whether combustion chamber properly seated
Check hidraulical connections
Check whether the circulation pump and the mixing valve is properly
connected.
Check whether the safety equipment properly connected.

3.2 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.

10
ThermoFLUX
Minitherm -
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 Minitherm -r 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 horizontal part 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.
3.3 Minimum distances of the stove from wall
and objects
A –minimum distance front - 100 cm
B –minimum distance from side - 20 cm
C –minimum distance back side- 20 cm
D –minimum distance from side - 20 cm
ThermoFLUX leaves itself the right to later perform changes without notice.

Air temperature indicator
Regulation on the stoves ''Minitherm'' 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 STAND-BY is ON )

5.2 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
Start PELLET IGN. Flame
