1. Boiler’s use
Wood is the main fuel for the Eko-Vimar Orlański boilers.
Wood at 15-25 % humidity and length about 5 cm smaller than the loading chamber should be
used as the main fuel (billet’s diameter - 15-25 cm - check „technical data”).
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 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
temperature’s range and protects the boiler against its overheating by fan’s turning
on.

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
according open system boilers’ producing should be taken into account. These norms and
rules should be followed, however, caution is required as national rules in countries in which the
product is sold may replace above-mentioned norms.
In case of boiler assembly outside the Poland, rules and norms should be followed according
to solid fuel boiler assembly in countries in which the product is sold. Eko-Vimar Orlanski wood
gasi cation boilers type SUPER are adjusted for installation in closed systems.
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 CHOOSING
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 placing”.
4. There shouldn’t be any cables nor electric installations which aren’t for boiler room using.
Rys.1 Orlan-W boiler placing.
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 of the boiler. Such method of wood
burning allows 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).

5
Chimney sweep should approve smoke outlet before its connecting to a chimney ue.
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 of the norm above.

4.3. The functions of EKOSTER 2 regulator
Use
The microprocessor temperature regulator for central heating boiler is designed to control the air
blow in wood-red boiler and to actuate 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 a blower,
• setting the blower power (service mode),
• programmable boiler „blow-through”,
• automatic control switch-off after boiler burnout (extinguishes),
• blower interlocking 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
settings,
• control panel connecting possibility,
• room thermostat cooperation,
• automatic turning off in case of wrong burning up in the boiler,
• EKOSTER CONTROL cooperation.
Regulator working description
After switching on, the regulator passes into state signalled by switching on of
corresponding 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
receptacle 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 interlocking signalled by pulsation of
indicator, enabling feeding of fuel into the boiler. Automatic return to operation
pressing.

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 (in the type 3.4: +97 °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 excees over the set one, regulator will turn the fan ON from time to time.
NOTE!
- setting the blow-through time to „0” causes blow-through switching off,
- above temperature of 85 °C (in the type 3.4: +98 °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.

9
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 (65 °C), after room thermostat’s connecting we
change regulation for below 65 °C (in the type 3.4: +65 °C up to +90 °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
difference from the one set by regulator will turn into or (10 °C - 30 °C)
ex. dt = 20, temperature set = 70 °C after temperature’s decreasing to 50 °C (temperature
decreased of set „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 blower in % (3:30 % - 10:100 %).

6. Connecting and exploitation
6.1. Connecting
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 doesn’t procees 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 temperatures
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 15 up to 25 % humidity. Using different kinds 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).
Right quality of wood warranties proper boiler’s working. Using the fuel at different parameters
doesn’t guarantee correct boiler’s operating.

15
6.3. Accumulation
The best results in heating gives boiler’s connecting with an accumulation tank. Such installation
causes less wood using - even up to 40 %. Gasication process (if it runs in optimum way) generates
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 uctuaction 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
accelerates 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.
12. When the boiler reaches 60 ° C fan will start working automatically.
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cat-ion chamber and
thickness 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 chamber 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 7).
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.

17
NOTICE!
Lack of fuel is signalled with a red indicator .
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. Optimum 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 water 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
happens 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).
NOTICE!
Water temperature in a system with accumulation tanks at the boiler outlet should be
80 ° C.

18
IMPORTANT!
In the longer periods of the boiler stand-by it is advisable to unplag it.
7. Conservation
7.1. Boiler’s conservation
Except for the elements described 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
occuring 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.
IMPORTANT!
It is advisable to control the boiler annually in order to
prepare it for the next heating season.
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.
IMPORTANT!
It is unacceptable that the boiler works with the lower
door opened as then its 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.

19
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
leakproof 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 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!

Four steps to clean out the exchanger (except for the SUPER 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.
