Darkening Of Sauna Walls; Ventilation In The Sauna Room - Harvia Concept R Installation Und Betriebsanleitung

7.3. Darkening of sauna walls

It is normal for the wooden surfaces in the sauna room to darken over time. Darkening may be acceler-
ated by
• sunlight
• sauna heater heat
• protective materials for wall surfaces (protective materials have poor heat resistance)
• fine particles loosening from the sauna heater stones and rising with air currents.

7.4. Ventilation in the sauna room

The temperature sensor must always be installed in the specified place. If the minimum
distance from the supply air vent is not met, the ventilation must be altered!
Do not position the supply air vent so that the air flow cools the heat sensor!
• The air in the sauna room should change six times an hour.
• Mechanical ventilation: The supply air vent must be located in the upper part of the sauna so that
it does not interfere with the operation of the temperature sensor. (Figure 9. Minimum distance from
the supply air vent to the temperature sensor)
• Pressure ventilation: The supply air vent should be installed below or next to the sauna heater. The
diameter of the supply air vent should be between 50 mm and 100 mm.
• Exhaust air vent: Place the exhaust air vent as far away from the sauna heater as possible and close
to the floor. The diameter of the exhaust air vent should be twice the diameter of the supply air vent.
• Possible drain valve (closed during heating and bathing). You can also dry the sauna by leaving the
door open after the sauna.
• If the exhaust air vent is on the washroom side, the threshold gap of the sauna door must be at least
100 mm. Mechanical exhaust ventilation is mandatory.
