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 AT THE SAME ZONE.

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
