1. GENERAL DATA
IMPORTANT! Carefully select the heater for the volume of the room. A heater with a small
heang capacity will require a more intensive heang during a longer me, which will
shorten its service life.
Kindly note that:
When selecng a heater, it is necessary to give consideraon to the material of the walls
and the ceiling of the room of installaon. If they are not heat-insulated (concrete, brick,
glass, etc.), a heater of greater power is required, and addional 1.2 m3 of volume should be
added per each square meter of surfaces made of such materials. If the walls are made of
massive logs, the design cubing shall be increased by a factor of 1.5.
Example 1:
A bath house room volume equals 10 m3. The bath house has a 3-m wide and 2-m high brick
wall. Calculaons: 10+2х3х1.2 = 17.2. Consequently, this room is equivalent for a bath house
room with a volume of approximately 17 m3.
Example 2:
A bath house room volume equals 10 m3. The bath house has a 0.8-m wide and 2-m high
glass door. Calculaons: 10+2х0.8х1.2 = 11.9. Consequently, this room is equivalent for a
bath house room with a volume of approximately 12 m3.
Example 3:
A bath house room volume equals 10 m3. The bath house walls are made of massive logs.
Calculaons: 10х1.5=15. Consequently, this room is equivalent for a bath house room with a
volume of approximately 15 m3.
2. OPERATION MANUAL
Read this manual carefully before commencing installaon and operang the heater. Keep it
for future use.
2.1. Safety measures
IMPORTANT! Consult your doctor about your health-related limitaons. Bear in mind
that prolonged exposure to hot bath house environment can be harmful. Avoid being in a
heated bath house and steam bathing under the inuence of alcohol, drugs, medicaons,
etc. Do not sleep in the heated bath house. Take care while moving around in the bath
house as benches and oor can be wet and slippery.
IMPORTANT! Consult your pediatrician whether vising bath house and steam bathing
is allowed to your children. Do not let your children approach the heater. Do not leave
children as well as handicapped people and people with fragile health unaended in the
bath house.
IMPORTANT! Be careful with hot parts of the heater and stones, and also avoid pung
steam on, if you or someone else is near the stone heater, as it can cause burns.
IMPORTANT! In order to prevent re, do not use the steam room or the heater surface to
dry clothes or other objects.
Note: metal surfaces of the heater can corrode in coastal and humid climate.

2.2. Heater design and operaon
Note: overall view and locaon of the heater main elements are shown in Appendix 2. Internal
design and operaon of the heater is shown in Appendix 3.
Firebox, as well as other crical elements of the heater, is made of corrosion-resistant steel
of AISI 439 grade. Corrosion-resistant steel of AISI 310 grade is used for the above heater
elements in Retro models, which extends heater operaon life signicantly due to enhanced
heat resistance and high-temperature strength.
The eecve design for heang up the stones and the steam room is due to numerous
bends, heat-conducng structural elements, which increase the heat dissipaon area. The
air heang and discharge system allowing to control convecon streams inside the steam
room, as well as heang an adjacent room, also plays a signicant role.
Heater models of Long version are equipped with retractable heang ue and ash drawer that
allow adjusng the length depending on the wall thickness, and also allow ring the heater
from the adjacent room.
Note: dimensions of heaters with a telescopic heang ue are shown in Table 1 and
Appendix 1 as a range of values.
All heater models can be oponally equipped with special reinforcing devices (refer to Appendix
4) made of heat resistant high-alloyed corrosion-resistant steel, that enhance combuson and
addionally protect the heater rebox from destrucon due to exposure to high temperature.
The devices have ducts for supplying addional combuson air, and when it enters the rebox,
the air passes parally above the re into its upper part, where post-combuson of ue gases
occurs. Addional heat is generated during this process, thus enhancing the heater’s eciency.
There is a grate at the boom of the heater (refer to Appendix 4). Ash falls through the sheets
of the grate into the ash drawer, which allows convenient cleaning of the heater without
interrupon of burning. The grate is one of the most thermally loaded parts of the heater, it is
fabricated of high duty rolled steel with a thickness of 5 mm.
The heater rebox door is fabricated of steel and thermal glass. The door opening angle is
sucient for convenient loading of fuel and allows visual monitoring of the burning process due
to the availability of the glass.
The outer surface of the heater is covered with an-corrosion heat- resistant enamel.
IMPORTANT! Unauthorized modicaon of the heater is prohibited. The manufacturer
reserves the right to make modicaons to the design of the heater that do not impair its
consumer properes.
Retro series
Removable lid allows accessing to the inner compartment of the stone heater and also
serves as a steam restricng device. Water is supplied to the inner compartment of the
stone heater through funnels.
The heater allows having a bath house with exible temperature control, and achieving
various steam room modes:
Fine steam mode is a mode for special ultralight steam obtained by pouring water
through the funnels to the inner compartment of the stone heater, the stones in which
are heated up to temperatures above 400 °С, while having a moderate (60-70 °С) steam
room temperature. Owing to the special design, Retro is capable of restoring serviceability
of the inner stone heater aer pouring water (0.5-1 l) onto it, in less than a minute, and
connue operang in ne steam mode. Given the stone heater lid is installed conguously
and the pressure is growing, the steam escapes through a nozzle located on the lid imitang
the singing of blizzard. Hand-formed bricks, used as the heater cladding material, ensures
operaonal safety (precludes the propagaon of IR-radiaon, signicantly reduces the rinks

6
of burns), as well as has a greater heat capacity compared to metal cladding, which allows a
longer heat retenon. Stone cladding has the form of panels with a fastening system, which
signicantly speeds up the heater assembly and installaon.
IMPORTANT! Unauthorized modicaon of the heater is prohibited. The manufacturer
reserves the right to make modicaons to the design of the heater that do not impair its
consumer properes.
IMPORTANT! Overall views of the heaters and (or) of their elements may be slightly
dierent from the ones shown in the gures in documentaon, catalogue, promoonal
materials, on the website.
IMPORTANT! Hand-formed bricks may have cracks, chipped corners and parts, and can
dier in shape and dimensions, which is linked to peculiaries of manufacture, deburring
in parcular, and is not a defect.
Tradional steam mode is achieved when water is poured onto the outer stone heater at a
moderate (60-70 °С) steam room air temperature.
Finnish sauna mode is achieved at high air temperature in the steam room, and low
humidity. Water is not poured onto stone heaters.
2.3. Heater commissioning
It is recommended to preheat the heater prior to operaon. Compound for metal protecon
and volale components of the heat-resistant enamel evaporate as a result of heang up of
the heater.
Note: remove all packing elements and paper sckers before the rst heang up of the
heater.
The preferable opon for heang up is outdoors, away from combusble surfaces and
materials, in compliance with re safety measures and safe work pracces.
Install a poron of chimney stacks vercally (about 2 meters), load 3-4 logs into the heater
rebox and start up a re. Fully open the damper on the door to supply air for combuson.
Once the rewood begins to burn and stable dra develops, fully close the damper.
Add rewood into the rebox as it is consumed. Connue heang up unl smoke and odor
disappear.
IMPORTANT! During the rst heang up avoid the chance of mechanical impact on the
paint coang of the heater (do not put the stones into the stone heater, do not rub the
surface, do not pour water).
IMPORTANT! Do not heat up the heater at constant excessive dra which can lead to
heang of the rebox red hot, as this will reduce its service life. Adjust the dra via the
damper on the door.
IMPORTANT! Install the heater on the place of permanent operaon only aer complete
cooldown.
IMPORTANT! In case a water tank is installed, it shall be cleaned thoroughly before use.
The water tank shall be lled before heang.
2.4. Combuson material
Approved fuel type: dry wood, fuel briquees without arcial binder resins with a
maximum burning point less than 820 °C.
Recommended fuel type: hardwood with a moisture content not more than 20 % with a
maximum burning point less than 820 °C.

7
The moisture contained in the rewood has a signicant impact on the combuson process
and the heater eciency, hence to reduce the rate of soot formaon on the walls of the
chimney and the ues of the rebox, it is necessary to use the recommended fuel types.
Owing to the special design, Retro has an economical fuel consumpon, from 2-5 kg/h,
depending on the selected operang mode, characteriscs and thermal insulaon of the
room, combuson material quality, etc.
IMPORTANT! Dierent fuel types have dierent heat of combuson. When a large amount
of rewood with a high heat of combuson is burned, as well as when the heater is
operated at a constant excessive dra, the heater service life decreases.
IMPORTANT! The following is not recommended as fuel:
‒ coniferous, resinous tree species (spruce, r, pine, etc.);
‒ construcon and other materials containing chemicals, glue, etc.;
‒ vegetaon residues (grass, leaves, etc.).
IMPORTANT! The following is prohibited to be used as fuel:
‒ combusble materials with a high heat of combuson (coal, wood chipboard, plasc,
pellets, and so on);
‒ painted or impregnated wood;
‒ waste (plasc, rubber, texles, leather, etc.).
2.5. Stones for stone heater
The permissible stone sizes are given in Table 1.
Only the stones intended for bath house and sauna shall be used as heater stones. For lling
in the inner stone heater, please also use the stones included into the contents of delivery.
IMPORTANT! Put the stones into the heater only aer its complete cooldown.
• Clean the stones from dirt and dust before pung into the heater, thoroughly rinse them
with water.
• Fill in the inner compartment of the stone heater with stones up to no more than 70% of
the volume.
• Do not cover or shut o the nozzle located on the lid of the inner compartment of the
stone heater, while laying stones into it.
IMPORTANT! It is prohibited to use halite to ll stone heaters.
IMPORTANT! It is prohibited to lay stones between cladding panels and heater rebox. It
is allowed to lay stones solely into the inner stone heater and into the bowl of the outer
stone heater.
2.6. Heater operaon
IMPORTANT! Before each heang up of the heater, make sure that there are no foreign
objects in the rebox, ash drawer or in the chimney, and that there is chimney dra.
1. Remove all unnecessary and foreign objects from the rebox and chimney, remove ash
from the ash box.
2. Put 3-4 logs on the grate in such a way as to ensure free access of air to the combuson
area: lay the rewood loosely, fully open the damper of the door.
3. Ignite the rewood loaded into the rebox. The preferred ignion method is using
birch bark, wood chips and other natural materials, or using paper or throwaway
newspapers.
4. Close the door.

8
5. Partly close the ash drawer aer heang up of the chimney and development of
stable dra (usually aer burning of the rst load of rewood, approximately in 30-45
minutes), leaving a gap within 10 mm. It is necessary to constantly ensure sucient
dra, while avoiding the development of excessive one (it can manifest itself as
humming of the heater, too errac ame), that leads to heang of the rebox red hot,
which signicantly reduces the heater service life. Control the dra by adjusng the ash
drawer gap.
6. Close the ash drawer completely aer the air in the bath house heats up to a
temperature of 60-70 °C.
7. As a rule, 1-2 logs are enough to maintain the temperature in the steam room. In case
the temperature decreases, open the ash drawer and adjust the gap within 3-10 mm in
order to kindle the rewood (it takes more me, when the ash drawer is closed), and
close the ash drawer aerwards. If the temperature keeps decreasing, then adjust the
ash drawer gap within 3-10 mm and keep it unl the temperature reaches 60-70 °C,
then close the ash drawer. Bear in mind, that excessive heang (for example, several
full loads in a row) leads to overheang and shortens the heater and chimney service
life, and can also cause a re.
8. When addional rewood is required, open the door smoothly, without jerks. Load the
rewood and close the door. Adjust the dra.
9. Aer the compleon of bathing procedures prepare the room and the heater for
closing: they are to be aired and dried. To do so:
• Put 4-5 logs into the heater rebox, kindle them. Set the ash drawer gap to be
approximately 10 mm. Open the hatches/windows, that serve for airing, and the door
in order to develop a small dra.
Note: the air and the bath house to remain heated, the air to move barely noceably,
i.e. it shall be quite warm and even hot in the bath house (up to 60-70 °C).
• Heat up the bath house in this mode, the rewood will burn in approximately 30-45
minutes. Completely close the ash drawer aer formaon of acve red coals. Close the
hatches/windows and the door, leave the bath house unl next use.
• The room and the heater to be periodically checked aer such stokings: there shall be
no water or moisture in the stone heater, the stones shall be dry, and so shall be the
boards in the rooms. If the rooms and the heater did not dry thoroughly, it is allowed to
carry out addional stoking of the heater with a completely closed ash drawer.
For a faster heang up of the room, the heater upper and lower convecon dampers to
be fully open (refer to Appendix 2). Aer a sucient heang up, convecon intensity and
temperature in the room can be adjusted via the dampers: when the upper damper is fully
closed, convecon intensity decreases signicantly; when both are closed, convecon ceases
almost completely. The operang mode is selected individually based on own preferences.
The heater allows ne-tuning the micro climate in the steam room, as well heang air in
an adjacent room aer the connecon of air ducts: lower duct for supply of air for heang,
upper duct for discharge of hot air into the room.
IMPORTANT! The following is prohibited:
‒allowing rewood to burn inside the heang ue;
‒using explosive, toxic, highly ammable substances, paints, solvents, gasoline, etc., to
ignite the rewood;
‒operang the heater at a constant excessive dra in the rebox.

9
IMPORTANT!
• Paral burning out of heat-resistant enamel is possible on the most thermally loaded
elements of the heater during operaon, which is not a manufacturing defect.
• The rebox metal may become slightly deformed during operaon, which is not a
manufacturing defect provided the integrity of weld joints is preserved.
• In case there is a hot water tank, water shall be drained from the tank every me
aer terminaon of the heater operaon, if the room temperature drops below + 5 °С
during interrupons of the heater operaon.
2.7. Water in the bath house
The water poured onto the stones shall be clean tap water. Ensure the water quality. Water
with a high content of iron, salt, humus, or lime can lead to early corrosion of the heater
elements. For example, seawater will lead to rapid corrosion of the stone heater. The tap
water quality shall meet the following requirements:
‒humus content <12 mg/liter;
‒iron content <0.2 mg/liter;
‒calcium content <100 mg/liter;
‒manganese content <0.05 mg/liter.
IMPORTANT! Water shall only be poured onto the stones. If water is poured on heated
steel surfaces, they can be deformed due to high dierenal temperature.
IMPORTANT! It is prohibited to use salt soluon to generate steam during operaon:
pouring it onto the stone heater (if available), and the heater metal.
2.8. Maintenance
Roune maintenance of the chimney, heater and its parts is the key to their ecient and
safe operaon, your safety and safety of your close ones!
IMPORTANT! Carry out maintenance works on the heater and chimney only aer their
complete cooldown.
IMPORTANT! Take measures recommended for safety. Use personal protecve equipment
required for such works.
The heater and chimney shall be cleaned of soot before the commencement of the heang
season, as well as during the enre heang season at least once every three months. Cleaning
to be performed mechanically. Use special devices, tools and machines (brush, cleaner,
scraper, sinker, vacuum cleaner, etc.). The selecon of the necessary tools is made based
on the needs of the cleaning works. Cleaning the ue channels of the heater is carried out
through the cleanout hole aer removing the cap (refer to Appendix 2): unscrew both nuts,
remove the cap. Aer cleaning the ue channels, install the cap, makeup and ghten the nuts.
Soot in the chimney accumulated due to poor cleaning, as well as incomplete combuson of
fuel, can break into ames.
Procedure in case of re in the chimney:
1. Close the door, the ash drawer, and the ue damper (if available).
2. Call the local re department.
3. Do not aempt to exnguish the re with water.
4. Aer an ignion of soot, a specialist shall check the heater and the chimney for the
possibility of further operaon.
IMPORTANT! The use of cleaning log (briquees), homemade compounds creang high
temperature in the heater rebox and chimney, is prohibited for the purposes of burning
the soot deposited in them.

10
The stones deteriorate with me as the heater is operated, this is why it is necessary to
turn them over and reposion in the stone heater at least once a year, when the heater is
frequently operated. Remove the destroyed stones and their parts from the stone heater,
replace them with new ones. Before laying the stones, clean the heater with a wet cloth.
The ash drawer shall be cleaned at all mes before heang, so that the combuson air
passing through the ash drawer to cool the grate, thereby increasing its service life. If there
is a thermal glass door, use so cleaning waste with special agents for cleaning heat-
resistant glass of replaces and heaters in accordance with the applicaon instrucons.
Please, obey re safety rules!
2.9. Typical faults and troubleshoong methods
1) Fault: Odors appear during the heater operaon.
Possible cause:
• There is leover industrial oil on the heater surface, or/and the odor comes from heat-
resistant enamel.
• When heang up, the heater can enhance the odors present in the air, even if their
source is not the bath house itself or the bath house heater. Such sources, for example,
can be surfaces treated with paint, oil, glue and other materials.
Troubleshoong methods:
• Stoke the heater in accordance with paragraph 2.3.
• Select appropriate materials for treatment of the surfaces in the bath house; use them
in accordance with the applicaon instrucons.
2) Fault: The bath house room is not heang up.
Possible cause:
• The bath house room is too large for the heang capacity of the heater.
• Thermal insulaon of the room is not in compliance with the requirements.
• Insucient chimney dra.
• Low quality or wet combuson material.
• Blockage in the chimney or ue channels of the heater.
Troubleshoong methods:
• Check that the heater capacity matches the size of the bath house (secon 1).
• Check the thermal insulaon of the room (secon 1).
• Check combuson material for compliance (paragraph 2.4)
• Perform maintenance (paragraph 2.8).
3) Fault: The stones in the stone heater do not heat up.
Possible cause:
• The bath house room is too small for the heang capacity of the heater. The room is
heang up faster than the stones.
• Insucient chimney dra.
• Low quality or wet combuson material.
• Blockage in the chimney or ue channels of the heater.
• The stones are laid incorrectly.
Troubleshoong methods:
• Check that the compliance of the heater capacity against the bath house size (secon 1).
• Check combuson material for compliance with the requirements (paragraph 2.4).
• Perform maintenance (paragraph 2.8).
• Inspect the stone heater for compliance with the requirements (paragraph 2.5). Remove
