1.3. Heating of the Sauna Using the Steamer

With the Combi heater, the sauna can be heated
either in the usual way or by using its evaporator.
Always fill the water reservoir before use!
•
The evaporator has a 1,3 gal (5 l) water tank
•
so it can be on continuously for approximately
2 hours. The tank should be filled when the
heater is cold.

1.3.1. Filling the Water Reservoir
