Blackening Of The Sauna Walls; Sauna Room Ventilation; Sauna Room Hygiene - Harvia Spirit Instructions D'installation Et Mode D'emploi

Blackening of the Sauna Walls

It is perfectly normal for the wooden surfaces of the sauna room to blacken in time. The blackening may be accelerated by:
• sunlight
• heat from the heater
• protective agents on the walls (protective agents have a poor heat resistance level)
• fine particles disintegrating from the sauna stones which rise with the air flow.

Sauna room ventilation

The air in the sauna room should change six times per hour. Figure 11 illustrates different sauna room ventilation
options.
Note! Do not place the supply air vent so that the air flow cools the temperature sensor

A. Placement area for air supply vent (Ø 50 – 100 mm). If mechanical ventilation is used, air supply vent should be
placed above the heater. If natural ventilation is used, air supply vent should be placed under or next to the heater.
The diameter of the supply air pipe must be 50–100 mm.
B. Exhaust air vent (Ø 100 – 200 mm). Place the exhaust air vent near the floor, as far away from the heater as
possible. The diameter of the exhaust air pipe should be twice the diameter of the supply air pipe.
C. Optional vent for drying (closed during heating and bathing). The sauna can also be dried by leaving the door open
after bathing.
D. If the exhaust air vent is in the washroom (Ø 100 – 200 mm), the gap underneath the sauna door must be at least
100 mm. Mechanical exhaust ventilation is mandatory.

Sauna Room Hygiene

• Bench towels should be used during bathing to prevent sweat from getting onto the benches.
• The benches, walls and floor of the sauna should be washed thoroughly at least every six months. Use a scrubbing
brush and sauna detergent.
• Wipe dust and dirt from the heater with a damp cloth. Remove lime stains from the heater using a 10% citric acid
solution and rinse.
