6. AIR EXCHANGE FOR THE STEAM ROOM:
- The air exchange in the steam room must be as efcient as possible, in order to
guarantee sufcient oxygen content and availability of fresh air. The air in the steam room
should be changed 3-6 times in an hour.
It is recommended that the ventilation be realised in accordance with the HVAC designer’s plan
- The fresh air is directed through a ca. 100-mm diameter duct. The outlet duct should be larger
in diameter than the inlet duct. If the ventilation is mechanical, we recommend placing the inlet
air valve in the ceiling near the heater. Locate the temperature sensor at a sufcient distance
from the inlet air valve!
- There must be a space of at least 1,000 mm between the temperature sensor and
the fresh air duct or 500 mm if the duct end can be turned.
- If the ventilation is natural, we recommend placing the inlet air valve on the side of the heater
or under it, either in the wall or in the oor.
- It is important to introduce fresh air, so that the air mixes with the air and the steam.
- The exiting air should be exhausted from near the oor as far as possible from the incoming air.
- The air exhaust valve may be located under the sauna benches.
- The exiting air may be directed out of the steam room through the washroom,
for instance under the door. There must be an approximately 100-150-wide slit
between the door and the oor.
- If you provide your sauna with a separate drying valve, place it in the ceiling of the steam room.
(This valve shall be closed during the use of the sauna.)
7. CONSTRUCTION OF THE STEAM ROOM:
- The steam room must be well insulated, especially the ceiling, through which most of the steam
escapes. Because of the humidity, it is recommended the insulation be covered with a moisture
resistant material, for instance aluminum foil. The surface (panels) of the sauna rooms interior should
always be wooden or made of non-combustible material.
- Floor is recommended to be of dark color, because water impurity and stones may stain lighter oor
materials.
8. PROTECTIVE BARRIER:
- A protective barrier may be built around the heater if necessary. In this case, you should
denitely adhere to the minimum clearances from structures made of ammable materials.

9. IMPORTANT ADDITIONAL INSTRUCTIONS:
- A suitable temperature for the sauna room is between 60–80 °C.
- Staying in the hot sauna for a longer time, makes the body temperature rise, which may be dangerous.
Do not sleep in sauna.
- You should be careful in the vicinity of the hot heater, because the stones and
metal parts of the heater may cause burns.
- Only a small amount of water (1-2 dl) should be thrown onto the heater stones, because
the steaming water is scalding hot.
