Environmental instructions
Packing Packing is made of 100 % waste materials.
Dispose of packing in accordance with local
waste disposal requirements.
Removal from Service The boiler should be delivered to a waste dis-
posal point for electric and electronic compo-
nents.
Operating Principle
ECONATURE-40 is a solid-fuel water-
heating boiler operating on a rotating combus-
tion principle designed for heating systems in
private houses. The rotating combustion tech-
nique used in ECONATURE-40 is even 30 %
more energy saving than the conservative
upper burning technique.
Firewood Burning Phases
DRYING: Dehumidification of firewood.
PYROLYTIC DECOMPOSITION: Wood starts to
break apart and change to coal and gas. Pyro-
lytic decomposition begins at a temperature
above 100 ºC; when the temperature exceeds
280ºC the resulting reaction causes heat re-
lease. Secondary combustion (the reaction
between pyrolytic gases and oxygen) begins
at a temperature over 600 ºC.
REMAINING COAL BURNING: Remaining coal
burns after pyrolytic gases are removed.
After firewood starts to burn the temperature
must rise quickly since secondary burning
will not be efficient until the combustion tem-
perature is high enough. Efficient and clean
combustion implies full control over the burn-
ing process throughout its phases. The rotat-
ing combustion technique uses secondary
firewood burning efficiently where flue gases
provide additional burning in a separate firing
throat and obtain the hottest and cleanest
flame possible simultaneously reducing haz-
ardous flue gas emissions notably. During the
secondary burning process, the flame tem-
perature exceeds 1000 ºC making combustion
efficient and clean.

Installation
When installing follow the requirements be-
low.
The boiler should be installed upright on a
safe level support/surface. There are four ad-
justable legs supplied with the boiler.
It is recommended to fit the boiler with a flue
gas sensor.
Boiler Room
Leave free space of at least 1000 m in front of
the filling and maintenance hatches of the
boiler, at least 600 mm over the cleanout
hatch, and 400 mm on one side of the boiler.
Combustion air required for the boiler is sup-
plied from outside and the duct or valve area
should be at least half as large as the stack
area.
Stack
The stack should be round, Ø 150 mm, whole
brick lined.
The minimum required boiler draft is 10 Pa.
The stack should be high enough to prevent
flue gases from polluting environment nearby.
Piping Installation
The boiler is always connected to a 1800-
3000 liter energy accumulator.
We recommend to install three thermometers
into the battery: bottom, middle, and top.
The system should be fitted with shutoff val-
ves in order to ensure easy filling and empty-
ing of the boiler, accumulator, and heating
system.
The boiler should contain at least one 1.5 bar
safety relief valve with a blowoff capacity of
at least 150 kg/h if the maximum boiler power
is 60 kW. The blowoff capacity can be dis-
tributed among two or three (maximum)
valves if necessary. To confirm functionality,
at least two safety relief valves are recom-
mended to be used at all times, each having
the required blowoff capacity. The blowoff
line of the safety valve should be laid to the
floor drain to ensure that the drain can be no-
ticed and escaping vapor cannot constitute a
hazard for people or property.
The volume of the membrane expansion tank
should be at least 5 % of the entire water spa-
ce in the system.
Piping should be installed to ensure that boiler
operation, maintenance, and cleaning are un-
obstructed.
Electric Wiring
The boiler power supply is 230 V / 50 Hz. The wiring should be connected to the termi-
nal block located behind the openable sensor
panel.

Boiler Operation and Maintenance
Fuel
Use dry firewood for burning. Using wet fi-
rewood will absorb energy during evaporation
and remove most of it through the stack as
unburnt flue gases, thus uselessly loosing part
of energy and resulting in soot formation in
the stack.
Firewood is considered dry when the moisture
content is 20 %. Such wood is lighter in
weight and smashing logs against each other
produces a clearer sound.
ECONATURE-40 is mainly designed for
birch firewood which has a length of 50 cm, a
diameter of 12 cm, and a weight of 1.5 to 1.9
kg.
Other foliferous and coniferous woods are
also suitable for combustion but coniferous
woods cause more contamination to the boi-
ler. Different woods burn differently. Lighter
woods with a smaller wood diameter will
burn better.
Start-up
Check that:
•The flue is open and there is no installa-
tion or other waste at its base.
•The boiler and the heating system are fil-
led with water and circulation is working.
•Piping connections are tight.
•The system is under pressure.
•The safety relief valve is working, i.e.
water runs from the drain line during val-
ve testing.
Use a small amount of firewood for the first
burning to avoid bar splitting by boiling water
that could soak in the ceramic fire bar.
If the system is filled for the first time the air
dissolved in water will penetrate into the sys-
tem but will be removed from the boiler water
when the temperature exceeds 90 ºC. When
used for the first time, the system should be
deaerated.

Control Panel
1. Pressure gauge. Measures pressure in the
boiler.
2. Thermometer. Measures water tempera-
ture in the boiler.
3. Pump thermostat 60-90 ºC. Activates
the charging pump when the boiler water
achieves the setpoint. The setpoint should
be at least 85 ºC under normal operating
conditions.
4. Smoke exhauster thermostat 90 ºC. De-
activates the smoke exhauster if the boiler
water achieves the setpoint of 90 ºC.
5. Flue gas thermostat 0-150 ºC. Deacti-
vates the smoke exhauster when the flue
gas temperature drops to the setpoint.
6. Power switch. The power switch of the
smoke exhauster and the charging pump.
7. Pump thermostat indicator lamp. On
when the pump is on.
8. Flue gas thermostat indicator lamp. On
when the smoke exhauster is on.
9. Temperature limiter. Deactivates the
smoke exhauster and the charging pump if
the boiler water temperature exceeds
98 ºC. The limiter will not actuate unless
the instrumentation is improperly used or
until it fails. Acknowledgement is pro-
vided by opening the protective cap and
pressing the limiter. Note that the boiler
water should cool down before acknowl-
edgement.

Firewood burning
•Position the power switch (6) to ON.
•Put about eight 50 cm long pieces of
wood evenly onto the fire bar, altogether
weighing about 6 kg, and insert paper or
birch bark in between to ensure ignition.
•Fire the wood and start the smoke ex-
hauster by rotating the thermostat to posi-
tion 0. The filling hatch is kept slightly
open during ignition.
•Wait 15-20 minutes to allow about a 10
cm layer of live coals to form on the bar.
•Charge blocks (about 18-20 birch logs
altogether weighing about 32 kg) evenly
and closely, bark upward, onto the bar so
that the blocks touch the rear wall of the
furnace.
•Set the smoke exhauster thermostat to the
setpoint which is about 90 ºC. The set-
point is correct if the smoke exhauster
stops when there is a small amount of
coals left in the boiler.
•Put new blocks onto the remaining coals.
One firewood charge will burn about 2.5
hours producing about 100 kW heat, i.e. a
1800 liter energy accumulator will be heated
to approximately 50 ºC.
If the boiler has not been used for a long whi-
le, use a small amount of firewood for the
first burning to avoid bar splitting by boiling
water that could soak in the ceramic fire bar.
Charge the firewood on the fire bar so that
it does not block the firing hole located in
the middle of the bar.

11
Combustion Air Control
For clean boiler convection surfaces, the flue
gas temperature should be approximately 170
ºC. Raising temperature by increasing power
will reduce the boiler efficiency. Too low
power should not be used either as this will
drop the flue gas temperature below 150 ºC
due to corrosion hazard.
The required air quantity and ratio for burning
varies depending on the wood to be burnt.
Primary and secondary air is factory adjusted
for birch firewood.
Upper primary air does not have to be ad-
justed under normal operating conditions.
Lower primary air should be adjusted when
the boiler power needs to be changed. The
boiler power grows in correlation with the
flame length.
Secondary air can be adjusted when the boiler
water temperature has been unchanged for 45
minutes after the beginning of combustion.

SECONDARY AIR ADJUSTMENT
FLAME CAUSE ADJUSTMENT
Red flame with black swirling. Secondary air is not enough for
burning. The stack discharges
black or dark smoke.
Add secondary air.
Yellow white flame. Good air distribution. The
stack discharges light grey
smoke.
No need to adjust burning.
Dazzling white flame. Too much secondary air. The
stack discharges white smoke. Reduce the amount of secon- dary air.
Maintenance
•Regularly check that the system is filled
with water; if you have to add water con-
stantly, then the system is leaking. Con-
stantly adding fresh water causes corro-
sion to the heating system since fresh wa-
ter contains air (oxygen).
•The hot system pressure should be lower
than 1.5 bar and the cold system pressure
higher than 0.5 bar ( 1.5 bar safety relief).
The water volume varies as the tempera-
ture, i.e. the higher the temperature, the
higher the volume and the pressure. The
expansion tank serves to smooth such vo-
lume variations.
•Check the pre-pressure of the expansion
tank at several years' intervals.
•Check the safety relief valves at least twi-
ce a year by rotating the knob/lever in or-
der to prevent sticking. Add water to the
system after the check.
•While burning firewood take care to en-
sure that the boiler water temperature is
always higher than the flue gas due point
i.e. at least 70 ºC and the flue gas tem-
perature is at least 150 ºC in order to pre-
vent corrosion.
•Remove ashes from the furnace and the
firing throat as required.

13
Cleaning
Keeping a daily watch on the burning process
in the boiler and making necessary adjust-
ments make the cleaning process a problem
free and infrequent job. Good burning forms a
thin grey or coffee colored layer on the firing
surfaces of the boiler, which falls off itself.
Poor burning forms a dirty layer of soot, as-
hes, and tar on the firing surfaces and inside
the flue. This prevents thermal energy from
transferring to water thus increasing the flue
gas temperature and lowering the efficiency.
Cleaning should be performed as follows:
1. Remove ashes from the fire bar and fur-
nace.
2. Remove turbulators from the convection
ducts.
3. Clean the convection ducts with a metal
brush.
4. Clean the firing surfaces with a metal
brush.
To control contamination of the boiler check
the flue gas temperature. When the tempera-
ture rises 30 …50 ºC higher as compared with
the clean boiler, it means that the boiler needs
to be cleaned.
Note that tar can stick to the walls of the stor-
age furnace, which is normal so you do not
have to clean the walls.
When cleaning the stack check also the smoke
exhauster blades.
Troubleshooting
The boiler water temperature does not rise to the desired level
•Ensure that the primary and secondary air
ratio and access are correct.
•Ensure that the firewood is dry.
•If there is a cooling coil in the boiler
•Make sure that the mixing valve functions
properly.
The boiler boils and sputters
•Ensure that there is enough water in the
system and the pressure is between 1 and
1.5 bar. If there is no water in the system
stop the heating process immediately by
extinguishing fire. Do not add water to the
boiler but let it cool down by driving cold
air through it. When the boiler is cool, you
can fill the system with water and restart
heating.
•Check that the pump and the mixing valve
are working and check the circulation
through the pump and piping. The air pre-
sent in the system can inhibit water circu-
lation.
•Ensure that the furnace bottom bricks are
in place and in good condition.
The flue gas temperature is too high
•Clean the boiler. Soot, ashes, and tar con-
taminate the firing surface and act as
thermal insulation.
•The flue gas temperature should not ex-
ceed 350 ºC as the boiler can break down
and the flues cannot withstand high tem-
peratures. Ensure that the primary and se-
condary air ratio and volume are correct.
•Ensure that turbulators are in place and in
good condition.
•Ensure that the firing throat seal is in good
order.

14
The flue gas temperature is too low
•Ensure that the primary and secondary air
ratio and volume are correct.
•Ensure that the firewood is dry.
•Shorten the turbulators if necessary by
removing the lower plate from each ele-
ment in order to increase the flue gas tem-
perature.
The extractor fan won't work
•Ensure that the boiler water temperature is
below 90 ºC and that the thermostat indi-
cator lamp is on since the set value of the
extractor thermostat is 90 ºC.
•Check the set value of the flue gas ther-
mostat.
•Check that the temperature limiter has not
tripped. For acknowledgement, open the
protective cap and press the limiter. How-
ever, let the boiler temperature cool down
before acknowledgement. Find out why
the temperature limiter tripped.
•If the extractor fan produces abnormal
sound when working the trouble can be
caused by a motor bearing or a blade.
•If the extractor power has dropped then
the blades have to be cleaned.
