2.7 If the sauna heater will not heat up
If the sauna heater will not heat up, please check that:
- the power is on;
- the main fuses of the sauna heater are intact;
- is there any error messages on the control panel. In case of an error message on the control
panel, please refer to the control panel instructions.
THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS AT THE
PREMISES FOR THE FUTURE USER.
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 7. 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 8 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 page 7
- 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
Follow the safety clearance specifications on page 7. Table 1 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 mini-
mum clearances specified on page 7 must be followed also in case the sauna room wall materials are incom-
bustible.
An optional stand is available for floor installation. The sauna heater must be fixed to the wall using the upper
fasteners even if the stand is used.
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.
