2.7 If the sauna heater will not heat up

If the sauna heater will not heat up, please check that:
1. The power is on; And the heater main switch is in position I (close to the thermostat dial)
2. The timer is on the heating zone (operating zone);
3. The thermostat is switched to a temperature that is higher than the current temperature of the sauna room;
4. The front fuses of the sauna heater are intact;
5. The timer is not stuck. Make sure the knob doesn't chafe against the base; there should be min 1mm gap
between the knob and the base.
If the sauna heater has been exposed to freezing conditions, the temperature limiter may have gone off. The
limiter is reset by pressing the reset switch. Note that the limiter does not work until the temperature has risen
to approx. -5°C. If the sauna heater still fails to work, please contact an authorised service for repair.

2.8 Preparing for sauna heater installation

Check the following before installing the sauna heater:
1. The ratio of the heater's input (kW) and the sauna room's volume (m
presented in Table 1 on page 8. The minimum and maximum volumes must not be exceeded.
2. The sauna room ceiling must be min 1900 mm high.
3. Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling
or wall surface adds 1.2 m
4. Check page 9. Table 2 section for a suitable fuse size (A) and the correct diameter of the power supply
cable (mm²) for the sauna heater in question.
5. Conform to the specified safety clearance around the sauna heater. There should be enough room around
the sauna heater for maintenance purposes, a doorway etc.

2.9 Installation

Note! The heater delivery box includes a template for easy installation.
Follow the safety clearance specifications on page 8. Image 2 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 8 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.
