1. GENERAL DATA
IMPORTANT! Carefully select the heater for the volume of the room. A heater with a small
heating capacity will require a more intensive heating during a longer time, which will
shorten its service life.
Kindly note that:
When selecting a heater, it is necessary to give consideration to the material of the walls
and the ceiling of the room of installation. If they are not heat-insulated (concrete, brick,
glass, etc.), a heater of greater power is required, and additional 1.2 m
3
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 sauna room volume equals 10 m
3
. The sauna has a 3-m wide and 2-m high brick wall. Cal-
culations: 10+2х3х1.2 = 17.2. Consequently, this room is equivalent for a sauna room with a
volume of approximately 17 m
3
.
Example 2:
A sauna room volume equals 10 m
3
. The sauna has a 0.8-m wide and 2-m high glass door.
Calculations: 10+2х0.8х1.2 = 11.9. Consequently, this room is equivalent for a sauna room
with a volume of approximately 12 m
3
.
Example 3:
A sauna room volume equals 10 m
3
. The sauna walls are made of massive logs. Calculations:
10х1.5=15. Consequently, this room is equivalent for a sauna room with a volume of ap-
proximately 15 m
3
.
2. OPERATION MANUAL
Read this manual carefully before commencing installation and operating the heater. Keep it
for future use.
2.1. Safety measures
IMPORTANT! Consult your doctor about your health-related limitations. Bear in mind that
prolonged exposure to hot sauna environment can be harmful. Avoid being in a heated
sauna and steam bathing under the influence of alcohol, drugs, medications, etc. Do not
sleep in the heated sauna. Take care while moving around in the sauna as benches and
floor can be wet and slippery.
IMPORTANT! Consult your pediatrician whether visiting sauna and steam bathing is al-
lowed 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 unattended in the sauna.
IMPORTANT! Be careful with hot parts of the heater and stones, and also avoid putting
steam on if you or someone else is near the stone heater, as it can cause burns.
IMPORTANT! Do not use the steam room or the heater surface to dry clothes or other
objects to prevent fire.
Note: metal surfaces of the heater can corrode in coastal and humid climate.
2.2. Heater design and operation
Note: overall view and location of the heater main elements are shown in Appendix 2. Internal
design and operation of the heater is shown in Appendix 3.
