“EasySteam” company's furnaces are made from stainless heat-resistant steel with chrome
content not less than 17%. The furnace body (point 1), which is 3 mm thick, is a complex bent-welded
structure with additional elements to reinforce the construction. There are convection canals (point 2)
on the outside of side-walls.
The protective heat-retaining shield (point 13), which is made of 2 mm thick construction
steel, is installed around the furnace. The clearances between the wall of the furnace and protective
cover are filled in with stones and make up an outer heater. A big amount of stones in the inner heater
will keep the temperature within the design limits and will facilitate subsequent dehumidification of
the sweating room.
Maintaining the flame temperature high inside the furnace is essential for the heating up of
the inner heater (point 3) to the uttermost. There are protective heat-retaining shields (point 4) made
of 20 mm chamotte tiles on the inner surface of the burner which help to redistribute the temperature
load inside the furnace, significantly increase the heat energy transfer to the bottom of the heater
and to take the load o the load-bearing wall.
The inner heater is a complex bent-welded reservoir made of 4 mm stainless steel in the
center of the furnace.
In order to equally distribute the load of massive heater's filling, the heater's bottom is made
semicircular that also lets to increase the heating area and to prevent the bottom elevated-
temperature deformation. Maintenance of the equipment is done through the steam pipe (point 5).
Due to the fact that in the operating process the heater is one of the most loaded elements, total
mass of the filling shouldn't exceed the maximum value mentioned in this manual!
Steam generating unit (point 6), which is a complex system of vertical and horizontal pipes,
is installed in the heater to get high quality finely dispersed steam. Pin-holes are made in horizontal
pipes to ensure even distribution of steam-water mixture over the most heated-up bottom layer of
the heater's filling. The dispensing unit (point 7) is attached to the upper part of the steam generating
unit. There is a safety (back pressure) valve in order to prevent an unpermitted emission of steam-
water mixture in the opposite direction.
Before usage, it is necessary to check the performance capability of the dispensing unit. Remove
(screw o) the dispensing unit and examine the safety valve. In case of discovering of foreign
object (small pieces of bath besom or so on), remove them and wash the device properly.
Performance capability of the safety valve is checked by shaking if the valve is functional, you will
hear a distinctive sound of valve jingling in both ways which indicates that nothing blocks its
movement.

The boiler grate (point 8) is installed at the bottom of the furnace. Through the slots in the
grate the air comes to the heater which is essential for high-temperature combustion process.
Combustion products also get to the ash box (point 12) through the boiler grate.
At the top of the furnace there is a flue-gases outlet (point 9), a steam pipe (point 5), a pipe
of a steam generating unit to connect it to the dispensing unit, and a cleanout port (point 14).
The cleanout port serves to clean and examine manufacturing clearances between the
heater and the furnace body. Examine manufacturing clearances not less than once a year or when
there is a diculty of a chimney draft. In case if there is a lot of soot in the clearances, clear it o with a
flexible brush for smoke pipes (pic.1). In order to get to cleanout port, ease o the cap nut on the lid of
the cleanout port with a 13 mm wrench. While lifting the nut up, make three full rotations (don't
unscrew the nut completely) then move the lid of the cleanout port aside and take it out of the port.
Put the lid of the cleanout port back after the examination and tighten the cap nut.
The front of a furnace consists of a specially shaped frame with a door (point 11) and air
governor (point 15) attached to it.
The front of a furnace and its body are separated by the fuel channel (point 10) which allows
lighting the furnace from a room adjacent to the sweating one.
The furnace is painted with black organosilicone enamel.

FURNACE PREPERATION FOR
EXPOLOITATION
Before installation, you should test-light the furnace outdoors for 4-5 hours. During the first
burning, all technical components (dirt, occupational dust and so on), which got on the furnace
during the transportation and warehouse or production storage, will burn out.
Before putting the furnace into exploitation, make sure that all installation works were
completed according to the requirements of this manual or to instructions for constituent parts made
by other supplier!
When developing your banyas' project and installing the furnace, it is NECESSARY to ensure that
all fire safety standards mentioned in the Code of Practice (CP) 112.13330.2011* “Fire safety of
buildings and facilities” and CP 7.13130.2013 “Heating, ventilation and conditioning. Fire safety
requirements. With Amendment No.1 & Amendment No.2” are met. Non-compliance with safety
standards can cause a fire.
Furnace and chimney should be regularly checked. In case if there is any malfunction of the
equipment, you should immediately stop exploiting the furnace and contact our specialists to
get a troubleshooting assistance on a possible cause of this failure and remedial procedures to fix
it.
Our main chimneys are made of stainless heat-resistant steel AISI 316 (310, 321) with wall thickness
not less than 0.8 mm in the brick or stone veneer which is fixated with a decorative sheet
(economizer).
The pass-through in floors and in the roof should be made fire-proofed according to the CP
7.13130.2013. The floor in front of the door should be covered with a metal sheet in size of 700*500 mm in
order to shield it from the combustible materials.
Combined extract-and-input ventilation is installed in the sweating room to insure good
ventilation.
In the far corner away from the furnace, there is should be a small window under the ceiling to remove
the carbon dioxide accumulated during the respiration.
The minimum distance between the cover and inflammable surfaces is 500 mm.
The protective heat-resisting shield in the front of the furnace should be as high as the full height
of the room (pic 2).
While in operation the furnace has a thermal expansion of 3-5 mm. This should be taken into
account in the process of installation.
It is prohibited to place the flue channel of the furnace outside. The furnace cannot be lighted up
from the outdoors.

Not every type of stone is suitable for the furnace! Undefined stones of unknown origin should not
be used!
As the filling for the inner heater we recommend you to use following stones: gabbro-diabase, jadeite,
quartzite, quartz, porphyrite, jasper and so on. They have high heat absorption capacity, don't
contain any harmful impurities and won't be aected by changes of temperature. Before laying
stones in the heater, clean them of any foreign particles and wash properly with hot water.
On the bottom of the heater, under the steam generating unit, lay stones of 100х80х70 mm
fraction. Then it is recommended to lay bigger stones and fill up cavities with smaller fractions.
In order to avoid damaging the furnace, it is not recommended to make a monolithic-type laying of
stones. You should always leave some space between the stones. Total mass of the filling shouldn't
exceed the maximum value mentioned in this manual!

Burner units are installed in the burner and fixated with fasteners. For more detailed information on
the installation, utilization and technical characteristics see the instructions for burner units.
The appearance of burners unit may dier from the one presented in the picture 2
The laying of the filling in the inner heater is done through the steam pipe at the top of the
furnace. The laying of the filling in the outer heater is done through clearances between the cover and
the wall.

Side walls of the protective cover (point 1) are attached to legs (point 1) with screws (point 3).
Put the assembled protective cover on the furnace (the cut-out notch should be placed on the flue
chimney side). The clearances between the wall of the furnace and protective cover are filled in with
stones (this makes up an outer heater). Then put boards (point 5) on the top. Lay stones on the top of
the furnace.

STRUCTURE OF HOT WATER
PRODUCTION SYSTEM
In the system of hot water production there are 2 main elements: heat-exchange unit (point
1) and water receiving tank (point 2) connected by pipes.
Heat-exchange unit is a rectangular tank with a volume of 3,5 liters. Its function is heating
up of water by receiving heat of the furnace. The heat-exchange unit is attached directly to the side
wall of the furnace. There are one inch threaded joints (points 3 and 4) on the top and on the bottom of
the heat-exchange unit that connect pipe-lines to the side-mounted tank.
Heat-exchange unit is a structural section of the furnace. When the furnace is heated up, it is not
allowed to fill up the system if there is no water in the water level gauge of the side-mounted
water receiving tank.
Constant exploitation of the system without water is not permitted because it leads to short life of
a furnace.
Side-mounted water receiving tank is a rectangular, cylindrical or dierent shape reservoir
(shape and dimensions can vary based on customers wishes and technical peculiarities of the
installation site). At the top of a tank there is a tank fillet pipe (point 5) which is needed to fill the system
with water, with a hermetic lid (point 6) and one inch threaded joint (point 7) for steam removal from
indoor space. There are one inch threaded inlet and outlet joints (points 8 and 9) at the bottom of a
tank. The hot water faucet (point 10) is on the front wall of a tank. All water receiving tanks are
equipped with water level gauges which allow monitoring water level while in operation.
Fill the tank with water not exceeding upper point of the water level gauge.
The heat-exchange unit and water receiving tank are connected by metal pipes (points 11 and 12) one
inch in diameter. There is a T-tube (point 13) with connected discharge pipe on the bottom tube which
allows discharging water system via faucet (point 14) in wintertime.
In circumstances when the distance between heat-exchange unit and water receiving tank is
less than 1 metre, when water level lowers while in use or when the furnace burns for more than 3
hours, water can start boiling. Water boiling goes along with insignificant noise.
To prevent boiling add some cold water in the system (if water level lowers when in use).
Choose water receiving tank based on assumption that there's should be 15 litres per person plus 10
litres to steam the bath besom.

OPERATION OF HOT WATER
PRODUCTION SYSTEM
14
To start the system, unscrew the lid and fill the tank with water.
Fill the system with water before lighting up the furnace. It's prohibited to fill the empty system
when the furnace is hot!
When the furnace is burning, its walls release the heat, a significant part of which goes to
the heat-exchange unit and heats up the water. The process of natural water circulation starts as a
consequence of water temperature dierences in heat-exchange unit and water receiving tank.
Water from heat-exchange unit and water from water receiving tank start to mix up. The system
starts to operate.
Open a faucet (point 10) on the front wall of the tank to get hot water.
Estimated time of water heating to the temperature of 80 degrees is between two and
three hours and depends on layout of heat-exchange unit and water receiving tank connection as
well as on their physical distance.
In case if there is a big distance between heat-exchange unit and water receiving tank or when
the geometry of inlet pipes is complex, cut the low-power circulating pump into the system.
The process of system heating up is inevitably linked to a process of water evaporation. The higher
water temperature in the system, the more intensive the process of evaporation. All generated steam
should be removed from indoor space via exhaust steam pipe.
Exhaust steam pipe must be regularly examined before each burning of the furnace. For the
purpose of your own safety and maintaining systems' working capacity, avoid pipes full or partial
clogging.
To prevent breaks during winter, don't leave the water in the system!

When installing the hot water production system, pay special attention to equipments'
location. The heat-exchange unit should be placed in such a way to minimize the distance to water
receiving tank and connect them in the most eective and practic way possible.
Water receiving tank should be placed in such a way that tanks' bottom surface would be
not less than 100 mm higher than the top surface of the heat-exchage unit.
Maximum margin between the top surface of a heat-exchage unit and tanks' bottom
surface should be not more than 2 meteres. The water receiving tank is attached to the wall, in order
to do that there are fasteners on the back wall of the tank.
Systems are connected via metal pipes and pipe branches. Avoid sagging of the connecting
pipes, as they must be sloped from water receiving tank to heat-exchange unit.
Each additional bend of connecting pipes negatively aect the process of circulation.
Connect water receiving tank and heat-exchange unit, avoiding unnecessary bends of
connecting pipes.
You should only use high-temperature materials (flax fiber) as a seal for threaded
connection joints of the heat-exchange unit.
To remove the steam from indoor space, connect the steam outlet joint to a pipe (hose)
which removes the steam.
Place one end of the pipe (hose) somewhere where coming out steam would be safe for people
around! When in use, watch carefully for the hose, so it doesn't have any bends!
For safe exploitation, tank should be covered with a wooden crate.
Pipes connecting the heat-exchange unit and water-receiving tank should be free to move in
places where they pass through the cover made of bricks or natural stones. The diameter of the
passage in the cover made of bricks or natural stones should be 5-10 mm larger than the pipes
coming out of the heat-exchange unit.

ASSEMBLY SCHEME FOR THE VENEER

FURNACE OPERATION
Proper burning of the furnace significantly increases the service life and reduces a risk of fire
breaking-out. A recommended heater's load is 50-70 % of its volume. The most appropriate fuel for
the furnace is dry wood of deciduous hardwood trees (birches, aspens, alders). High quality fuel
briquettes made of pressed sawdust may also be used.
It is prohibited to burn coal or peat in the furnace.
High-temperature combustion is a process directly connected with oxygen input, which is
regulated by using the air governor.
To light a furnace, put a woodpile (3-5 logs) in the burner.
Log must not be longer than the length specified in the technical specifications! This could lead to
smoking of the glass and overheating of the furnace portal.
Some time after firing up the furnace, an intensive combustion process starts, and high-
temperature gases go up through manufacturing clearances between the heater and the furnace
body as well as through the main chimney and engulf the heater in flames.
At the highest point high-temperature gases run against the top of the furnace and form a
circle around the heater, in so doing, enhancing the heating-up of the inner filling.
Oxygen, that is essential for high-temperature combustion in the lower part of the heater,
comes in directly through the boiler grate.
Proper installation of main chimney prevents flue gases from getting into the room even if the
furnace door is open.
Heating-up of the heater is directly connected to stones' (inner filling) heating-up.
Well heated heater guarantees that you'll enjoy your easy steam!
It is prohibited to light a furnace with highly inflammable liquids.
When in service, walls of the furnace and the heater can undergo a slight deformation, which
won't aect weld's leak-tightness. This is not a spoilage.
Before lighting the furnace, make sure that there are no combustion products left in the
burner and ash box, clean them if needed.

Protective shield absorbs direct radiation of heated furnace walls, prevents getting burns, makes
outcoming warmth even more gentle and comfortable.
Be careful! The process of water (volume of which is equal to one of the dispensing unit) transfor-
mation into the steam takes no longer than 5 seconds!
High quality steam is obtained by supplying water to the steam generating unit. From the dispensing
unit water gets in horizontal pipes where preliminary preparation happens (water transforms into
water-steam mixture). Then under the pressure, water-steam mixture comes out of small holes made
along the whole length of horizontal pipes into the most heated layer of heater's filling. Going from the
bottom up, water-steam mixture comes out of the steam pipe and fills the sweating room with an
easy steam. Every stone (total volume of the filling) is involved in the steam production process, that
why the steam comes out nothing else but finely dispersed (invisible) – easy! To get the steam you can
also use stones of the outer filling.
Chromium (Cr), as furnace compound, prevents oxygen combustion by metal surfaces of the
furnace!
In order to create true Russian banya temperature-humidity conditions in your sweating room,
the furnace is installed with protective heat-retaining shields.
