5. AIR EXCHANGE FOR THE STEAM ROOM
- The air exchange in the steam room must be as efficient as possible, in order to guarantee
sufficient oxygen content and availability of fresh air. The air in the steam roomshould 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 sufficient 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 floor.
- 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 floor 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 floor.
- 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.)
6. CONSTRUCTION OF SAUNA
- The sauna shall be well heat insulated, particularly the ceiling, where most of the steam rises.
Due to the high level of humidity, the heat insulation should be covered with moisture-proof
material, such as aluminium paper. Wood should always be used for cladding.
- The floor under the sauna heater must be heat resistant. Hot pieces of the stones might drop on
the floor from the heater and cause fire risk.
7. 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.
- This equipment is not to be used by children or people whose physical and psychological
traits, mental functions, lack of experience or knowledge may hinder the safe operation of the
equipment, if the person who is responsible for safety cannot supervise them or instruct them in
the use of the equipment.
- Do not go to the sauna if you are under the influence of substances causing intoxication.
- Children may not be left unsupervised and they should be supervised to make sure they do not
play with the equipment.
- Always inspect the steam room before plugging in the heater.
- The improperly filed stone container is a fire hazard.
- Covering the stove will cause a fire hazard.
- Do not place any objects top over the heater or dry clothes near by the heater.
- Door and window must be closed when using the heater.
