1. Boiler’s use
Wood is the main fuel for the Eko-Vimar Orlański boilers. Lignite or minced coil could be an alter-
native fuel.
Wood at 15-20% humidity and length at about 5 cm smaller than the loading chamber should be
used as the main fuel (billet’s diameter - 15-25 cm - check „technical data”).
Some alternative fuel is acceptable:
- lignite as 10-15 cm diameter blocks
- wood at different quality parameters (humidity) and mince range (shavings, furniture waste
and so on) is acceptable as the mix for the main fuel (50%/50%).
NOTICE!
Using different than ordinary fuel doesn’t guarantee boiler’s right operating - as it
was featured in technical data and it can inuence the boiler’s way of working and its
long-lasting.
NOTICE!
Using different type of fuel that the main one (including alternative one) is treated as
wrong boiler’s using and its effects can not be the reason for any complaint to the
producer.
NOTICE!
Wood boiler should be installed in open system together with an expansion tank (it
assures boiler’s working with nominal pressure - look “technical data”).
NOTICE!
Wood boiler is equipped with a regulator which assures its working in right tempera-
ture’s range and protects the boiler against its overheating by fan’s turning on.
2. Procedure rule
Wood gasication boilers work in pirolitic wood distillation process. When the air is limited
wood changes into charcoal while burning up. In the same time wood gas appears, which next
relocates to burner’s nozzle and there it is burnt at the bottom part of the boiler. Such method of
wood burning allow for its effective using as fuel. Orlan boilers are made for burning wood billets
(use minced wood only as an addition - it should be mixed with bigger wood parts as not to allow
for burner’s nozzle littering).

3. Installation
Wood boilers are to be installed according to the present norms and rules. The requirements of
norm PN 87/B 02411 according building of solid fuel boiler room and the norm PN-91/B-02413 ac-
cording open system boilers’ producing should be taken into account.
Eko-Vimar Orlański company prescribes using chimney inputs which preserve against the
chimney permeating. The company doesn’t take responsibility in case of faults resulting from not
using chimney inputs.
1. Chimney ue should correspond to the parameters of „DIAGRAM OF CHIMNEY CHOSING
ACCORDING TO THE DIN 4705 NORM”.
2. Boiler room should be large enough to enable boiler’s cleaning (>2,2 m).
3. The distance between the boiler and the partitions should enable right access for all of the
boiler’s parts - it shouldn’t be less than - look at “Orlan boiler’s placing”.
Orlan boiler’s placing
4. There shouldn’t be any cables nor electric installations which aren’t for boiler’s room using.
Before smoke outlet’s connecting to the chimney ue, there should be a chimney sweep’s ap-
proval.
According to the PN-EN 303-5 norm accumulation tank should be assembled together with wood
boiler - its capacity is listed in reference to the . 4.2.5. point in the norm

4. Regulator’s description
Since the 30.06.2006 wood boilers were equipped with RK 2001 regulator. In 01.07.2006 new
ones were brought out - EKOSTER 2. Main functions of both regulators are similar, but there is a
difference in parameters’ modication ( EKOSTER 2 ).

lisationl
If in 30 minutes temperature doesn’t reach 60°C, the indicator (8) and the fan will turn on.
Wrong burning up
signallization
If the boiler doesn’t reach 60°C during burning up (up to 2 hours) , the indicator (8) will light
up and the fan will turn off.
NOTICE! In the case wood can remain in the boiler.
Fan’s operating
controlling
Regulator modulates fan’s operating and it upholds its depending on boiler’s temperature.
Pump’s operating
controlling
If pump is connected to regulator:
• while burning up pump is turned off till the time when boiler reaches 65°C
• when here is more than 65°C the pump still works till the time of temperature decreasing
(60°C) then it stops. Next time it activates when temperature reaches over 65°C
Room temperature
controlling
Boiler comes together with the sensor which can be placed in the room. Regulator control
with the boiler’s work in such a way that it keeps temperature needed in the room.
Cooperation with
room thermostat
Boiler can cooperate with any room thermostat* which should be connected instead of a
room thermostat
* NOTICE! If there is a room sensor or room thermostat connected to the boiler then
the boiler will stay in watching stage and then its continuous temperature is 60 - 65°C. If
temperature decreases under the needed one , boiler starts working again.
Scavenging Regulator can ush of the loading chamber in order to get rid of gathered wood gas. The
function activates while boiler’s lay over after reaching the temperature congurated. When
the boiler reaches the temperature 10% higher from the one setted on regulator, ushing
function will turn off till the time of the temperature’s decreasing to the level underneath.
Flushing time is 5 seconds , timing interval between next ushes depends on the regulator
settings and it is 1 up to 9 minutes.
NOTICE! Technical service should deal with ushing regulation.
4.3. Pump’s and room sensor’s connecting
There is a connecting board at the back side of regulator where pump and room sensor can be
connected. The access for connecting board is possible only after the regulator’s disconnecting
and safety lid unscrewing. At the back panel there are some graphic markers and descriptions
featuring right elements’ connection placement.

4.6. The functions of EKOSTER 2
Use
The microprocessor temperature regulator for central heating boiler is designed to control the air
blow in wood-red boiler and to actuate the circulating pump in central heating system
The regulator performs the following functions:
• maintaining the set temperature of boiler by controlling air blow,
• smooths start-up of blower,
• setting the blower power (service mode),
• programmable boiler “blow-through”,
• automatic control switch-off after boiler burnout (extinguishes),
• blower disable when feeding the boiler,
• control of central heating circulating pump depending on its set operating temperature,
• „COMFORT SYSTEM”,
• protection against freezing or overheating of boiler,
• signalling of temperature sensor’s damage,
• regulating the brightness of display - increased during read out and change of regulator set-
tings,
• control panel connecting possibility,
• room thermostat cooperation,
• automatic turning off in case of wrong burning up in the boiler.
Regulator’s working description
After switching on, the regulator passes into state signalled by switching on of cor-
responding lamp. Operation commences after pressing button or automatically when
boiler’s temperature rises above operating threshold - that is, difference between set boiler
temperature and factory-set temperature difference “dt”. Automatic transition into state
occurs 30 minutes after boiler temperature drops below operating threshold. CONTROL recepta-
cle is for connecting remote control.
Pushbuttons and serve to change the settings. During normal operation, pressing them
causes display and change of set boiler temperature. Pressing and holding pressed causes
increase in speed of temperature setting change.
Pressing the button causes:
• with temperature below operating threshold: switching on or switching off control, signalled
by or indicators respectively,
• with temperature above operating threshold: blower disable signalled by pulsation of
indicator, enabling feeding of fuel into the boiler. Automatic return to operation .

NOTICE!
If the “Er” appears on the screen it means that temperature either raised over 99°C, it
decreased below -9°C or the sensor got damaged. To secure together the boiler and
installation up to the time of the sensor replacing pump should be continuously on till
that time.

COMFORT SYSTEM facility
The COMFORT SYSTEM function built into the regulator prevents against stone deposition
between pump rotor and stator. The regulator automatically actuates the pump after the heating
season for about 30 seconds, every 14 days. Operation of the pump in this mode is signalled by
pulsation of PUMP indicator. The system begins to operate 1 minute after regulator’s switching
on. Actuation of the pump in automatic mode causes re-counting of the 14-day period from the
beginning.
Antifreeze and overheating protection system.
When the temperature decreases below 4°C regulator secures the installation against its freezing
by the pump’s turning on. Temperature’s rising to more than 90°C causes the fan’s turning off and
the pump’s turning on. The button beating alarms of the boiler’s overheating. In the case
reasons for overheating should be found, eliminated and as it follows boiler should be engaged
again by the button pressing. Pump is continuously on in case of the temperature’s
sensor breaking down.
Programming of blow-through
• Press and hold for about 3 s until the OPERATING TIME indicator switches on,
• set the blow-through time in seconds with pushbuttons , ,
• Press
• set the blow-through interval in minutes with pushbuttons , ,
• Press .
If the temperature excess over the set one, regulator will turn the fan off from time to time.
NOTE!
- setting the blow-through time to “0” causes blow-through switching off,
- above temperature of 85°C, blow-through is switched off to prevent overheating of
the boiler.
Remote control
Regulator is accommodated for the remote „EKOSTER Control” connecting, which enables to
control and change current boiler’s temperature, preview of the pump connection and START-
STOP mode, in the same time sonic gauge alarms when the boiler’s temperature abruptly
increases to hazardous level. Remote control with 10 m wire doesn’t go as a standard set - they
are to be bought separately.
Service mode
It is for regulator’ s settings changes. To work on the mode you should:
• Swtch off the power,
• Switch the power back and in the time of some regulator’s version displaying (for example
2.2) press the button and hold it up to the moment of “HI” appearing on the screen.
Since the time screen alternately shows the symbol and value of regulation task.
With , buttons the value can be changed and button causes moving to the next
regulation settings.

10
Settings in correct order:
• „HI”: hysteresis of boiler’s temperature regulation (2°C - 9°C), that is temperature’s decreasing
to the low enough to cause fan’s turning on.
• „Po”: temperature when the pump turns on (35°C - 70°C), after room thermostat’s connecting
we change regulation for below 65°C till the time when „rP” appears on a display - Ekoster
on basis of the signal transmitted by the room regulator will control with pump’s working on
its own.
• „dt”: temperatures’ difference at the beginning of working, that is on what temerature’s dif-
ference from the one setted by regulator will turn into or (10°C - 30°C)
ex. dt=20, temperature setted = 70°C after temperature’s decreasing to 50°C (temperature
decreased of setted „dt” parameter from boiler setted temperature) regulator holds on for
30 minutes to burn out the rest of the fuel, after the fan turns off signalling in the same time
fuel shortage with diode.
• „┌ ┐”: max power of the ower in % (2:20% - 10:100%).
Installation instructions
1. Temperature regulator is designed for operating with central heating boilers.
2. Regulator’s connection is to be done by an authorized person only.
3. Regulator should be placed in the room enabling its warming to more than 40°C.
4. Installing should be made according to MONTAGE features.
5. The regulator must be safeguarded against spilling of water and against conditions causing
condensation of vapour (e.g. sudden changes in ambient’s temperature).
6. The device should be installed and operated in accordance with the principles of procedure
with electrical equipment.
7. Fuse burnout does not constitute basis for warranty repair.
8. It is recommended to check the regulator settings before starting up the boiler.
9. The regulator is protected with 1.25 A fuse.
10. Sensor is to be montaged with no oil.
NOTICE!
Connecting up of the pump supply cables as well as replacement of fuse should be
done with regulator supply switched off (regulator supply plug removed from the
supply socket). Connecting up the pump with regulator supply plug in supply socket
forms electric shock hazard.

6. Connecting and exploitation
6.1. Connection
Four-way mixing valve is essential for any installation. It’s role is to mix hot water (contribution
water) with the one returning from the system. Water mixing is necessary as to avoid „cold return
of the water” and to keep the same temperature of the boiler. What follows the temperature of
heating system’s feeding can be lowered to the temperature of satisfactionary warmth in the
house. Mixing valves should be used both in gravity system and with extorted ow (pump).

6.2. Wood and gasication
It is important that wood gasication boilers worked in specic conditions. Boiler’s temperature
accounts for 70 - 80°C. At lower temperatures gasication process doesn’t proceed in a correct
way and what follows - wood intake is relatively higher. Wood drying in a loading chamber is an
essential stage in gasication process - wood doesn’t have adequate temperature at lower tem-
peratures and all of the process is inadequate. Main warmth source in Orlan boilers is gas ame
arising during gasication , if main conditions according correct burning process aren’t taken,
then both quality and quantity of released gas won’t be sufcient.
Very important are: quality, humidity and kind of burned wood. Hard wood is the best - (beech,
oak, hornbeam etc.) at 25 up to 15% humidity. Using different kind of wood, such as pine, spruce
etc. is possible but there will be more burning waste at the sides and it will be necessary to load
the chamber more often. Hygrometer is for humidity measuring - it helps to select wood at best
quality (there is a guideline diagram of wood’s humidity on the next page).
NOTICE!
Mixing valve „1” should be set-
ted at 50% mixing

6.3. Accumulation
The best results in heating gives boiler’s connecting with an accumulation tank. Such installation
causes less wood’s using - even up to 40%. Gasication process (if it runs in optimum way) gen-
erates large gas quantity, heating system however is characteristic for large uctuation amplitude
in warmth requirement scope. Gasication process is set only in certain way, heating system uc-
tuaction change more often, room might get overheated or some extra gas can get through the
chimney. Accumulation system allows for gas storing in an accumulation tank. Heating system
is contributed by accumulation tanks for about 48 h (depending on tanks’ capacity and thermal
conditions - at about 50 l of water for 1 kW of power). If the boiler cooperates with accumulation
tank, its long lasting is lengthened.
6.4. Starting
Before rst boiler’s use there should be checked: leakproof of the threaded joints (whether there
isn’t any leak) installation water level, the parameters of boiler’s operating are to be set as well.
6.5. Burning up
The steps to be taken to burn up in the boiler:
1. Switch off the power
2. Push the chimney ap (gas pass opened)
3. Place splinters and some bigger wood pieces to the boiler upper chamber
4. Burn the paper and close the upper door
5. Open the bottom door as to provide natural draught
6. Wait for about 15 - 20 min. for better wood burning
7. Put that much of wood to get the right quantity of embers which will cover boiler’s bottom

(ca. 10 cm) (chopping of the wood in about 5 cm pieces at the rst stage of burning up ac-
celerates embers’ producing)
8. Wait for 15÷20 minutes for the ember layer occurring
9. Fill up the whole combustion chamber
10. Close the upper and bottom door hermetically
11. Pull the chimney ap and switch on the fan
WARNING!
It is forbidden to switch on the fan when the upper door is opened.
IMPORTANT!
It is important to pay an attention on both depth of gasication chamber and thick-
ness of the upper door while chamber’s loading. If wood’s sizes aren’t adequate to the
elements mentioned above it may be difcult to close boiler’s door or load the cham-
ber with wood. You must not close the door by force - it may cause door’s damage.
IMPORTANT!
Wood storing for about a year ensures its right humidity (admissable humidity - 25%
- look at TECHNICAL DATA section). Advisable humidity level (15%) is to be obtained
after 2 years wood storing (look at the diagram no 5).
6.6. Fuel loading
If the boiler is chosen adequate to the place to be warmed up there is one loading for 8÷12 hours
needed. It is advisable however to control the boiler every 5÷7 hours. To control wood quantity
you should:
1. Switch off the boiler with the main switch,
2. Open the chimney ap,
3. Open the upper door and load the chamber if it’s necessary,
4. Close the door, chimney ap and switch on the boiler
It is important not to let the fuel to get between combustion chamber and chimney ap as it
would obstruct chimney ap’s closing.
When loading (it is recommended to burn out the fuel up to embers) there is a need of taking
down ash deposited on the loading chamber’s sidewall.
NOTICE!
Lack of fuel is signalled with a yellow indicator “no fuel”

16
6.7. Boiler’s putting out
Boiler puts out in two ways: after turning off button pressing or after all of the wood burning out.
6.8. Right boiler’s temperature assuring
Right boiler’s temperature maintaining during its exploitation is very important. To assure correct
gasication process water temperature should be about 70°C.
In the time of a large warmth need returning water’s temperature may lower. If returning water is
about 20°C lower than contributing one, there is a risk of gasication chamber cooling and it can
result in boiler’s efciency decreasing (gasication process may be limited). As a result - pitch can
deposit at the boiler’s sidewalls. To avoid such situation there should be „little water circulation”
build in the boiler. To build it in three or four way mixing valve should be installed at the boiler’s
outlet. It mixes hot water with returning one. By correct hot and cold water setting, returning wa-
ter is warm enough as not to let for temperature’s rapid decreasing in the gasication chamber -
then gasication process correctly. Temperature’s difference 15÷20°C doesn’t cause large charge
of material of which boiler is made of and as a consequence it lengthen boiler’s exploitation time.
6.9. Power failure and pump’s breakdown
There is a risk of power deciency or pump’s breaking down during boiler’s exploitation. If it hap-
pens in winter time, fuel lling should be stopped. Boiler’s working with a chimney ap opened
is unacceptable. Boiler’s working with full chimney draught may cause its uncontrollable working
and as a consequence it can cause water’s boiling and boiler’s overheating. In case of extorted
circulation installation, current ow’s breakdown causes fan’s and pump’s turning off . The case
of wrong warmth passing on from the boiler to the heaters may cause water’s overheating. It’s
advisable to install an additional container such as water heater to avoid water’s overheating.
Its role is to assure min power taking from the boiler ex 5 kW for the 25 kW boiler. It protects the
boiler against its overheating.
NOTICE!
To protect the boiler and its electric equipment against network’s voltage excees it’s
advisable to use some constant - voltage regulator (e.g. computer strip).

7. Conservation
7.1. Boiler’s conservation
Except for the elements descried in „BOILER’S EXPLOITATION” preserving it is important that
the boiler was protected during its stagnation (summer time, householders’ absence). Boiler’s
interior, hest, exchanger, chimney ap should be cleaned through - it’s advisable to burn some
dry softwood (ex. spruce) in the boiler before its stopping over - it will burn out the waste occur-
ing during boiler’s exploitation. After boiler’s cleaning it should be left opened for aerating - in the
way you will avoid humidity condensation in the boiler.
7.2. Fan’s conservation
Fan is an essential boiler’s part. Keeping it in clean have a bearing on its longlasting. It’s advisable
to disassembly fan’s body from time to time and to clean it through (the waste deposited). Fan’s
blades can be cleaned with a soft bristle brush.
NOTICE!
Boiler’s working with the bottom door opened is unacceptable because in such a case
the fan can get overheated.
7.3. Boiler’s cleaning
The ash arising while burning process go down to the ash pit via the nozzle. The ash pit should
be cleaned every 3-5 days. Gasication chamber should be cleaned out between next burning
up. Ash is to be cleaned out via the nozzle - watch out as not to damage the boiler’s bottom. For
cleaning there should be used original appliances (enclosed as standard equipment). During
gasication process pitch occurs. Its quantity depends on wood, its humidity and contributing
and returning water’s temperature. It’s advisable to clean out gasication chamber with a scraper
(once a month). Carbon deposit subsiding at the pipes causes diminish of the exchanger’s section
and in the same time decreasing of the heat exchange. As a result it effects the thrust decreasing
and obstructs in heat transmitting. In accordance to this the exchanger’s pipes should be cleaned
out every two weeks to assure their permeability.
Four steps to clean out the exchanger (except for the SUPER 1 type)
1. Take off the boiler back upper casing
2. Turn on the nuts with M13 - M17 spanners (depending on boiler type). Important! Before
nuts turning on and turning off the thread should be preserved with a special anti corrosion
agent; do not turn on nuts with exertion
3. Each of the pipes in the exchanger should be cleaned with a cleaning shield. They should be
cleaned precisely in the whole length - it is important to avoid soot’s gathering at the bottom
part of the exchanger’s pipe and its blocking. Clean the soot deposited at the back part of the
chamber
4. It’s advisable to add some potato rind from time to time (about 10l). Potato starch works as
catalyst and it makes the matter of sediment burning out easier.

7.4. Leakproof securing
Leakproof of the boiler is very important especially leakproof of the door, the exchanger and
chimney ap. Leakproof causes the fumes’ coming out of the boiler and most of all it can cause
uncontrolled burning which may cause boiler’s overheating. To ensure the exchanger’s door leak-
proof the insulation rope should be sealed with a graphite oil or some other machine oil at least
once a week. It soften the rope and causes its tight adjoining to the boiler.
After some time of boiler’s operating (1 season for example) the door rope could get atted. To
assure right rope’s adjoining to the boiler’s door, door’s setting regulation is provided (regulation
on the hinge).
Hinge door setting:
a) take the door off
b) Loosen the cap
c) turn the hinge 360°
d) turn a tap tight to block hinge’s
regulating screw.
NOTICE!
Upper and down hinge should be
regulated in the same time.
Rys. 8 Cleaning elements
- only for STANDARD version
NOTICE!
Chimney ue’s leakproof should be controlled and if such a need occurs - it should be
cleaned out. All of the threaded elements before their unscrewing should be lubricat-
ed with grease. Door and hinges should be lubricated temporarily as well.

9. Allowance for Orlan super boilers
Wood boilers in version SUPER are equipped with a cooling coil (preserving against overheating)
and mechanical cleaning devices.
9.1. Cooling coil
In connection with thermostatic cooling valve cooling coil’s function is the boiler’s overheating
protection. We connect a cooling coil with thermostatic valve to the cold water installation (ex.
STS 20 Watts). Cooling coil outlet is to be directed into plughole installation.
9.2. Boilers’ cleaning
Mechanical cleaning devices allow for smoke tube heat exchanger’s keeping in clean. Cleaning
elements are made of spiral elements placed in pivot in furnace ue which are moved with a pivot
coming out of the boiler. It is important to use cleaning devices when boiler’s loading - it will stave
off their immobilizing with wood pitch.
