BEFORE INITIAL STARTING THE STOVE
Before initial starting of pellet stove for indoor central heating, following conditions
should be checked and confirmed:
- Is stove properly connected to electric power supply?
- Is stove properly connected to chimney?
- Distance from obstacles and flammable materials,
- Check the quality of fuel/pellet
- Is there a fresh air inlet in to the room and what is the quality of air circulation?
- How far is ambient temperature probe far from heat source?
Original probe cable is 80cm long so it is recommended to put probe 10cm above the floor.
Optionally, customer could use external thermostat (wireless thermostat) in which case it is
possible to connect it to stove.
- Is stove connected to a heating system in proper way?
-What is the quality and condition of residential heating system?
Before kindling the stove, it is preferable to inform stove user about maintenance
procedures:
- Daily maintenance
a) Cleaning of glass
b) Cleaning burning pot
- Weekly maintenance
a) Cleaning of glass
b) Cleaning burning pot
c) Cleaning of ashtray
- Monthly maintenance OR after 1 ton of used pellet
a) Cleaning of glass,
b) Cleaning of burning pot,
c) Cleaning of ashtray
d) Cleaning of Heat exchanging tubes connected to boiler,
e) Cleaning of space below boiler (Take out the ashtray and open Inspection covered
chamber),
f) Cleaning of chimney
- Seasonal maintenance
a) All above mention cleanings but also checking of all stove features and parts by
authorized person (it's recommendation that season maintenance is done by qualified technician)

ADJUSTING THE PELLET STOVE
Process of setting parameters is having 2 (two) phases:
1. Following and setting of starting fire (kindling), and establishing of stabile fire
2. Following and setting of working mode
Pellet stove is produced with basic settings included and those setting should be suitable
for majority of real situations which installer could meet in most of cases‚ but it is apsolutely
necessary to check pellet stove work (in several cycles of burning and cleaning burning pot).
REMARK: Check if option “WINTER SEASON” is turned ON
(There is instruction in OWNERS MANUAL how to turn it ON).
ENTERING THE MENU FOR SETTING PARAMETERS
To enter Menu for setting parameter you should do the following:
- Press the button SET (3) after which display will show MENU 01 SET CLOCK - Then use the
buttons (5) or (6) in order to reach 9.
Display will show MENU 09 SETTINGS TECHNIC
- Press the button SET (3). Display will show MENU 09 KEY ACCESS, which mean you should
enter the PASSWORD for entering parameters.
In upper left corner of the screen you will find symbol 00 .Press the button (1) to get to symbol
A9 (1,2,3,......98,99,A1,A2,...A9)
A9 is PASSWORD to enter PARAMETER SETTINGS
- Push the button SET (3), to enter parameter settings. Display will show N-9-1 TYPE PELLET.
- To exit parameters, push the button ON/OFF shortly for several times (4)
PHASE OF IGNITING/LIGHTING THE STOVE (LOAD PELLET)
In this phase it is necessary to control loading of burning pot with pellet and to check
quantity of pellet after initial loading which last 30 seconds. This period of time (30 sec.), is defined
with parameter N-9-4-03
In lighting/igniting phase, pile of pellet is filling 1/3 of burning pot (approximately, almost
closing the hole in burning pot which is made for Lighter/Igniter. Parameters which are influencing
igniting/lightning are:
- Parameter N 9-4-03 (30 seconds) initial loading of burning pot
- Parameter N 9-6-16 (1400 RPM.) Fan speed in lighting/igniting phase
- Parameter N 9-6-04 (0, 8’’) Time of loading pellet in lighting/igniting mode
* RPM stands for: Round per Minute
REMARK: working period + Auger pause = Auger cycle of 8 seconds ( If auger working
period is 0,8 seconds, than 7,2 seconds is period of auger pause.)

EXPLANATION OF STARTING FIRE PROCESS:
When igniter / lighter start to radiate heat, wood pellet is starting to produce gases. Heating of
that gases cause the small fire near the “hole which allows lighting ” which is drilled on burning pot.
After the critical temperature is reached, wood pellet starts to burn. In the moment of starting fire,
there should not be to much gases in the firebox because it could cause fire and explosion of gases.
Most usual causes of explosion are: small speed of exhaust gases fan, wet wood pellet, weak
igniter, overdose of pellet in burning pot during lighting/igniting phase.
Basic setting of Fan speed in ignition phase is 1400 (Parameter N-9-6-16). Diameter and
height of chimney could influence preferred value of this parameter. (High fan speed in lightning
mode could influence the parameter in negative way because temperature of igniter will be
influenced by high speed of blowing fan. After initial pellet loading, Auger will make a brake of 100
seconds (Par. N-9-4-04), in order to wait for establishing of fire. After this, Ager will start working
according Parameter N-9-6-04 (0, 8’’) until the moment when stove starts to work with established
and stabile fire.

Burning pot with correct fumes / Burning pot with wrong fumes
ESTABLISHING FLAME (FLAME LIGHT):
When temperature probe of exhaust gases register increasing of temperature (40 °C) , stove
is entering in mode of establishing stabile flame. The aim of this phase is to increase temperature by
the burning the residual pellet in the burning pot. In the moment of entering working mode, there
should be a appropriate quantity of hot glowing ash (approx. 1/3 of burning pot).
Parameters which are influencing establishing fire phase are:
- Parameter N-9-6-05 (0,6'') Time of loading pellet in “Cleaning of burning pot mode "before stove
enter working mode

6
- Parameter N-9-6-17 (1500 RPM*) Speed of exhaust gasses fan in period between detecting stabile
fire and working mode
* RPM stands for : Round Per Minute
In this phase it is important to follow up the way of burning in the burning pot. In case of high
speed or low speed of exhaust fan, parameters should be tuned and corrected (depending on air flow
and draft of chimney). Check the look of flame, if the flame is “dancing” and wood pellet is
“bouncing” in the burning pot, fan speed should be reduced.
“Dancing fire” and “bouncing pellet” / Stabile and established fire
WORKING MODE
After entering working mode, Installer is obliged to monitor and to follow up the way stove is
working in Mode 5 and Mode 1 (maximum and minimum).
Stove is set to maximal power 14 kw (4 kW given to room, i 10 kW given to water), until in MODE
1, WORK MODULATION (on minimum) Power is set to 6kW (2,2 kW given to room and 3,5 kW
given to water). Thermal output is influenced by quality of pellet.
Having in mind that one working cycle of stove is determined with parameter N-9-6-3 (15 minutes)
and that cleaning is determined with parameter N-9-6-12 (30 second).
WARNING:
Installer is obliged to follow up at least 3 working cycles including cleaning of burning pot
(both minimal and maximal values).
REMARK:
Parameters which are influencing cleaning of burning pot are:
- N-9-6-3 Time duration of burning pot cleaning. Every 15 minutes, exhaust gasses fan blowing is
increasing in order to clean burning pot.
- N-9-6-12 Time interval of burning pot cleaning (45 seconds)
- N-9-6-29 Fan speed during cleaning of burning pot (2100 RPM)
- N-9-6-30 Loading pellet during cleaning of burning pot (0,5 second)
In this phase it is important to follow up the way of burning fuel in the burning pot in order to
prevent high speed of exhaust fan which result with “bouncing pellet”

“Bouncing pellet” / Fuel is entering and burnining in correct way
IMPORTANT!!! There are two (2) cases which are inconvenient for installer / user:
1. Sometimes, after the cleaning of
burning pot, quantity of hot glowing
ash is smaller than it was last time. In
time, this quantity will be smaller and
smaller and finally, there will be no
hot glowing ash in the pot.
When new working cycle of 15
minutes comes, pellet is entering in
the empty burning pot and it doesn’t
start to burn. This “pile” of unburned
pellet is growing in the pot and
temperature in firebox is falling down.
This lower temperature is detected by
the temperature probe and in time,
Sound alert “NO FIRE” is appearing.
This moment is determined with
parameter N-9-6-13 (50 °C).
Solution to this problem:
- If you decide to leave 15 minutes
working cycle that interval of burning pot
cleaning should be reduced (from 30 to 25
seconds).
- If you decide to leave interval of
burning pot cleaning (30s) than you should
increase interval of working cycle (from 15 to
20 minutes)
- You should reduce speed of exhaust fan
(without changing other parameters)
- You should reduce speed of exhaust fan
from 2100 RPM to some lower value.
This lower value must be set according to
assessment and visual impression.
Installer is obliged to follow up at least 3-5
working cycles including cleaning of
burning pot to get this impression.
It is important to make this by adjusting
regimes of stove in Mode 1 and in Mode 5.

2. Sometimes, after the cleaning of
burning pot, quantity of hot glowing
ash is bigger than it was last time. In
time, this quantity will be bigger and
bigger and finally, there will be to
much hot glowing ash in the pot. In
this case, when, quantity of glowing
ash is bigger than 2/3 of pot, air flow
is disabled and pellet is not burning
properly.
It is most important to be careful with
this case because unburned pellet and
glowing ash could spill over in to the
ashtray or create layer which will
block entrance trough witch pellet is
falling from auger to burning pot. This
could result with fire inside auger
and consequently inside fuel
storage.
Solution to this problem:
- Before you start changing the Parameters you
should check if the stove is sealed properly
because false air could be one of the reasons of
the problem.
Check the sealing gasket, on doors and
burning pot, position of burning pot,
Check if the ALL Inspection covers are
properly closed and condition of chimney).
Also, wet pellet could be one of the reasons
for this problem.
- Increase speed of exhaust fan (without
changing other parameters)
- If you decide to leave 15 minutes working
cycle that interval of burning pot
cleaning should be increased (from 30 to 35
seconds).
- If you decide to leave interval of burning pot
cleaning (30s) than you should decease interval
of working cycle (from 15 to 10 minutes)
It is important to make this by adjusting
regimes of stove in Mode 1 and in Mode 5
RECOMENDATIONS RELATED CHIMNEY:
Before installing of stove check if chimney is build according regulations and condition of
chimney. If there are some damages, they must be repaired.
For fume exhaust, classic chimney made of brick and chimney made of metal tubes are both suitable.
In case of tubes, the must be SEALED and INSULATED in order to prevent condensation.
Stove cannot be installed without chimney!
If that is the case, TIM SISTEM have no legal or any other responsibility for
damage and injuries caused by inappropriate installation and use or for any kind
of disfunctionality of the stove. This case must be noted to user!!!!
Following characteristics of chimney are mandatory:
a) Top of the chimney must be resistant to strong winds
b) Top of the chimney must be covered and protected from the rain and snow
c) Maximal diameter should not be bigger than 16cm (or 15x15 cm),
d) Maximal height should not be bigger than 5m

9
e) Connection between exhaust tube and chimney must be sealed
f) There must be Inspection control hole
g) “T” Inspection tube for collecting condensate
Stove is constructed in way that it is connected to chimney with tubes of 80mm diameter.
Flexible tubes are not allowed!
All mounted tubes and their connections must be hermetic.
ONLY ONE STOVE CAN BE MOUNTED PER CHIMNEY
ONLY ONE CHIMNEY CAN BE CONNECTED TO THE STOVE
The f is constructed in such a way that it is connected to the chimney with 80 mm diameter
flue pipes. Flexible hoses for connecting the stove to the chimney are not allowed. Installation of flue
pipes from the furnace to the chimney should be done in such a way that they are hermetically. The
stove must be installed only on one chimney (external or internal) and only one stove can be installed
on one chimney.
It is not permissible for the gases to run through the wall only through a horizontal pipe (see
figure below), due to possible disturbances to the operation of the furnace in the case of wind. In this
case, inform the user of the stove that it is obliged to install the vertical part of the flue pipe (insulted,
with double wall) with the obligatory cap on the top of the stove (wind protection).
Flue gasses outlet.: unsatisfactory / satisfactory

NEW FIRMWARE:
- Serbian Language
- Separate cleaning parameters for regime's P1/P2 and P3/P4/P5
- 3 different option for entering into STAND BY (by ambient temp., by water temper. or by external
thermostat temperature)
- new way of using external thermostat
Main improvements is:
In old firmware cleaning process of burning pot was defined by 4 parameters:
- speed of exhaust fan through cleaning process (was the same value for all 5 regimes modes)
- duration between two cleaning process (in minutes)
- duration of cleaning period (in seconds)
- auger work in cleaning mode
All parameters above parameters had the same values, no matter that stove is working on
minimum power or maximum power (and sometimes it's difficult to adjust cleaning for both max.
and min. power settings)
Changes are reflected in the way that cleaning mode is separated on 2 parts:
- cleaning mode with their parameters for regimes P1 and P2,
Parameters
speed of exhaust fan N-9-4-12
duration between two cleaning process
N-9-4-13
duration of cleaning period
N-9-4-14
auger work in cleaning mode
N-9-4-15
- cleaning mode with their parameters for regimes P3, P4 and P5
Parameters
speed of exhaust fan N-9-6-03
duration between two cleaning process
N-9-6-12
duration of cleaning period
N-9-6-20

STAND BY mode:
By default when user activate STAND BY mode, stove is entering into and exit from STAND
BY mode only by following water temperature .
If ambient temperature is reached some preset value of room temperature, and temperature of
water is below some preset values then stove goes into MODULATION mode.
By default it is entering into STAND BY mode by following water temperature, but technician can
chose three different mode options for activating STAND BY mode in technical menu:
N-9-6-36 (value 00)
Stove goes into STAND BY mode
following ambient temperature
If water temperature is reach
some preset water temperature
value, then stoves goes into
modulation (as long as water is
below 80
o
C),
Technician must activate this
mode in technical menu
N-9-6-36 (value 01)
Stove goes into STAND BY mode
following water temperature
(default)
If room temperature is reach
some preset room temperature
value, then stoves goes into
modulation,
User can choose ON or OFF
(directly from display)
N-9-6-36 (value 02)
Stove goes into STAND BY mode
following external room
thermostat ( in that case ambient
probe on stove back is automatically
disabled, and temperature probe on
external thermostat is primary)
If water temperature is reach
some preset water temperature
value, then stoves goes into
modulation (as long as water is
below 80
o
C)
Technician must activate this
mode in technical menu
External thermostat thermostat
If you want to use an external programmable thermostat, connect it to the clamps at
back side ( see pictures at page 7 in user manual for connector position)
Connecting the room thermostat allows the stove to work through room temperature
control!
If it is water temperature is reached then stoves goes into modulation.
Note: if technician enable external thermostat in technical menu, then when user press key
1 or key 2 on both cases on display is present information about water temperature setting,
while room temperature is displayed on external thermostat.
If user don't want to use external thermostat no more, then again technician person
must disable external thermostat option in hidden technical menu.
