2.3. Recommended sauna room ventilation
Figure 1 Rekommended sauna room ventilation
1. Sauna room
3. Electric sauna heater
5. Exhaust flue or channel
2. Washroom
4. Exhaust valve
6. Door to the sauna room
7. A ventilation valve can be installed here to be kept closed while the sauna is heated and during bathing.
Inlet vent can be positioned in the A zone. Make sure the incoming fresh air will not interfere with (i.e. cool down) the
sauna heater's thermostat near the ceiling.
The B zone serves as the incoming air zone, if the sauna room isn't fitted with forced ventilation. In this case, the exhaust
valve is installed min 1m higher than the inlet valve.
DO NOT ISTALL INLET VALVE WITHIN ZONE C, IF THE SAUNA HEATER'S CONTROL THERMOSTAT IS LOCATED
IN THE SAME ZONE.
2.4. Installing the sensor near a supply air vent
The sauna room air should be exchanged six times in an
hour. The diameter of the supply air pipe should be
between 50 and 100 mm.
A circular air supply vent (360°) must be
installed at least 1000 mm away from the sensor.
An air supply vent with a flow-directing panel
(180°) must be installed at least 500 mm away from
the sensor. Air flow must be directed away from the
sensor.
2.5. Ceiling installation of the sensor
In ceiling installation, a 5-mm hole must be drilled to the sensor case to allow any condensed water to drain.
Do not spray water directly towards the sensor or splash water at it with a sauna scoop.
