1. If you have selected a wall-mounted heater, there needs to be a supporting structure for it behind the panelling boards. The mounting screws will not hold on panelling boards alone and the heater may fall onto the floor. In practice, sturdy boards for the mounting screws or a similar solution will suffice as a supporting structure. See the heater’s instruction manual for the locations of the mounting screws.
2. Familiarise yourself with the wiring required by the lights, the heater and the control unit (if one is used) and decide whether you want to have the cables under or on the panelling boards:
A. Wires for the temperature and/or humidity sensors of the heater
B. Electrical wiring for the heater
C. Wiring for the sauna lights
D. Any other wiring (special lights etc.)
3. Note that the benches require supports on the walls. There must be sturdy supporting structures behind the panelling boards for the bench supports.
