3. Preparing for sauna heater installation
Check the following before installing the sauna heater.
- The ratio of the heater's input (kW) and the sauna room's volume (m
3
). Volume recommendations are
presented in Table 1 on page 8. The minimum and maximum volumes must not be exceeded.
- The sauna room height must be a min. of 1900 mm.
- Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling
or wall surface adds 1.2 m
3
to the sauna room's volume.
- Check page 9 Table 2 for a suitable fuse size (A) and the correct diameter of the power supply cable (mm²)
for the sauna heater in question.
- Conform to the specified safe clearance around the sauna heater. Please refer to on page 8.
- There should be enough room around the sauna heater for maintenance purposes. Also a doorway can be
considered as a maintenance area.
3.1 Installation
Note! The installation template is printed on the lid of the sauna heater box.
Follow the safety clearance specifications on page 8 when installing the sauna heater. Thin panel is not a suitable
mounting base. The mounting base must be reinforced with timber behind the panel. The minimum clearances
specified on page 8 must be followed also in case the sauna room wall materials are incombustible.
An optional stand is available for floor installation. The sauna heater must be fixed to the wall using the upper fas-
teners even if the stand is used. For more detailed instructions, see page 7, paragraph 3.2.
Walls or ceilings must not be clad with fibre-reinforced plaster board or other light-weight cladding, because they
may cause a fire hazard.
A single sauna heater is allowed per a sauna room.
