1. Quick instructions for use of the sauna heater
1.1 Check before taking a sauna bath
- The sauna room is suitable for taking a sauna bath.
- The door and the window are closed.
- The sauna heater is topped with stones that comply with the manufacturer’s recommendations, the heating elements are covered with stones, and the stones are piled sparsely.
NOTE: Structural clay tiles are not allowed
1.2 Operation of the sauna heater controls
Set the heater’s thermostat to the desired temperature. You can find the ideal
temperature for taking a sauna bath by first turning the thermostat to the
maximum. Once the sauna room is warm enough, simply turn the thermostat
control backwards, i.e. counter-clockwise, until the heating elements turn off
(you can hear a clicking sound). You can fine-tune the temperature by slightly
turning the thermostat knob in either direction.
The sauna heater operates with a 12-hour timer.
The timer is operated by turning the timer knob clockwise from the 0 position.
In the 0 position, the power is off and the sauna heater is not on.
In the 1–4 hours zone, heating elements will turn on and the sauna heater is
warm for the selected period of time.
In the 1–8 hours zone, you can preset the time after which the sauna heater
will turn on. For example, by turning the knob at 6, the sauna heater will
turn on after six hours and stay warm for four hours unless the timer is
turned to 0 position earlier.
Pleasant, smooth sauna bath temperature is about 70 °C.
Rearrange the sauna stones at least once a year and replace any weathered
stones. This enhances air circulation between the stones, which extends the
useful life of the thermal resistors.
If you encounter any problems, please contact the manufacturer’s warranty
service shop.

1.3 Infromation for users
This appliance may not be used by children aged less than eight years, by
persons with reduced physical, sensory or mental capabilities, or by persons
lacking experience and knowledge regarding its operation only if such have
been given instructions on the safe use of the device and the risks involved.
Children must not be allowed to play with the appliance or to clean and
service it without supervision. (7.12 EN 60335-1:2012)
1.4 Sauna room
The walls and ceiling of a sauna room should be thermally well insulated. All
surfaces that store heat, such as tiled and stone surfaces must be insulated.
It is recommended to use wooden panel cladding inside the sauna room. If there
are heat storing elements in the sauna room, such as decorative stone, glass
etc., note that these elements may extend the pre-heating period even though
the sauna room is otherwise well insulated (see page 7, section 2,8).
2. Recommended sauna room ventilation
Before turning the sauna heater on, make sure the sauna room is suitable for
taking a sauna bath. When heated for the first time, the sauna heater may emit
some odour. If you detect any odour while the sauna heater warms up,
disconnect the sauna heater briefly, and air the room. Then turn the sauna
heater back on.
The sauna heater is turned on by twisting the timer knob, and the temperature
is adjusted from the thermostat knob.
Pleasant, smooth sauna bath temperature is about 70 °C.
You should turn the sauna heater on roughly an hour before you plan to take a
sauna bath, so that the stones have time to heat up properly and the air warms
up evenly in the sauna room.
Do not put any objects on the sauna heater. Do not dry clothes on the sauna
heater or anywhere in its vicinity.
2.1 Recommended sauna room ventilation
Inlet vent can be positioned in the A zone. Make sure the incoming fresh air
will not interfere with (i.e. cool down) the sauna heater’s thermostat near
the ceiling.
The B zone serves as the incoming air zone, if the sauna room isn’t fitted
with forced ventilation. In this case, the exhaust valve is installed min 1m
higher than the inlet valve.
DO NOT ISTALL INLET VALVE WITHIN ZONE C, IF THE SAUNA HEATER’S CONTROL THERMOSTAT IS LOCATED AT THE SAME ZONE.
2.2 Sauna heater stones
Quality stones meet the following requirements:
- Sauna stones should withstand heat and heat variation caused by vaporisation of the water thrown on the stones.
- Stones should be rinsed before use in order to avoid odour and dust.
- Sauna stones should have an uneven surface to supply a larger surface for the water to evaporate from.
- Sauna stones should be large enough, to allow good ventilation between the stones. This extends the useful life of the heating elements. It is recommended to use Vulkanite stones in the size of 5cm-10cm. E.g. Helo product 0043020
- Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the heating elements together or against the frame.
- Rearrange the stones regularly (at least once a year) and replace small and broken stones with new, larger stones.
- Stones are piled so that they cover the heating elements. Do not, however, pile a large heap of stones on the heating elements. For a sufficient amount of stones refer to Table 1 on page 9. Any small stones in the package of stones must not be piled on the sauna heater.
- The warranty does not cover defects resulting from poor ventilation caused by small and tightly packed stones.
- Structural clay tiles are not allowed. They may cause damage to the sauna heater that will not be covered by the warranty.
- Do not use soapstone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
- Do not use lava stone as sauna rocks. Any damages resulting from this will not be covered by the stove warranty.
- DO NOT USE THE HEATER WITHOUT STONES.
2.3 Sauna heater controls
2.3.1 Sauna heater
2.3.2 Timer switch
The sauna heater is controlled by operating a 12-hour timer with three
operating zones. The timer is set by twisting the knob clockwise until the
desired operating zone is reached. When operating, the timer gradually travels
counter-clockwise towards the zero position.
- 0 position. The sauna heater is not on.
- Operating zone 1–4 hours. Set on this zone, the sauna heater heats up at full power while the sauna thermostat controls the temperature.
- Preset zone 1–8 hours. Set on this zone, the sauna heater can be preset to turn on after a certain period of time. The heating elements will not heat up when the timer is within this zone.
Before turning the sauna heater on, make sure the sauna room is suitable for
taking a sauna bath.
The timer operates better if it is first turned further than the desired time
and then turned back to the desired time. If the switch has not travelled back
to 0 position after finishing bathing, turn it to 0 manually
2.3.3 Thermostat
The thermostat knob is next to the timer knob. The further right (clockwise)
the timer is switched, the higher the temperature will rise in the sauna room.
The best way to find the ideal temperature is to first turn the thermostat
fully on the right and let the temperature rise to the desired temperature.
Subsequently, turn the thermostat knob slowly counter-clockwise until you hear a gentle clicking sound. If you want to readjust the temperature, turn the thermostat gradually until the temperature is ideal.
The thermostat will not operate correctly if the stones are piled too densely or they are too small. Please refer to section ”Sauna heater stones” on page 5
The thermostat has an integrated temperature limiter with a reset switch next to the thermostat knob.
2.4 Electric heating toggle
Electric heating toggle applies to homes with an electric heating system.
The sauna heater thermostat also controls the heating toggle. In other words,
home heating turns on once the sauna thermostat cuts power off the sauna
heater
2.5 If the sauna heater will not heat up
If the sauna heater will not heat up, please check that:
- The power is on;
- The timer is on the heating zone (operating zone);
- The thermostat is switched to a temperature that is higher than the current temperature of the sauna room;
- The front fuses of the sauna heater are intact;
- 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
THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS TO THE PREMISES FOR THE FUTURE USER.
2.6 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 (m3). Volume/input recommendations are presented in Table 1 on page 9. The minimum and maximum volumes must not be exceeded.
- The sauna room ceiling must be min 1900 mm high.
- Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall surface adds 1.2 m3 to the sauna room’s volume.
- 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.
- Conform to the specified safety clearance around the sauna heater. Please refer to Image 3 Sauna heater safety clearances. There should be enough room around the sauna heater for maintenance purposes, a doorway etc.
2.7 Installation
Follow the safety clearance specifications on page 9. 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 9 table 1 must be followed also in case the sauna room wall
materials are in-combustible.
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.
2.7.1 Installation instructions
2.7.2 Sauna heaters safety clearances
2.8 Main connection
The sauna heater must be connected to the mains by a qualified electrician and
in compliance with current regulations. Sauna heater is connected with a semi-
permanent connection. Use H07RN-F (60245 IEC 66) cables or a corresponding
type. Other output cables (signal lamp, electric heating toggle) must also
adhere to these recommendations. Do not use PVC insulated cable as a
connection cable for the sauna heater.
A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control current fuse, the diameter of all cables must be the same, i.e. in accordance with the front fuse.
The connecting box on the sauna wall should be located within the minimum safety clearance specified for the sauna heater. The maximum height for the connection box is 500mm from the floor.
If the connection box is located at 500mm distance from the heater, the maximum height is 1000mm from the floor. (Image 4 on page 10: Location for the connecting box).
Sauna heater insulation resistance: The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause bleeder currents. The moisture will be gone after a few heating sessions. Do not connect the heater power supply through a ground fault interrupter.
However, always adhere to the effective electrical safety regulation when installing the sauna heater.
2.9 Electric heating toggle
Electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked N – 55) for controlling the electric
heating toggle. Connectors N – 55 and the heating elements are simultaneously
live (230V). The sauna heater thermostat also controls the heating toggle. In
other words, home heating turns on once the sauna thermostat cuts power off
the sauna heater.
2.10 Location the connection box for connection cable in the sauna room
A = Specified minimum safety clearance
1. Recommended location for the connection box
2. Silumin box recommended in this area.
3. This area should be avoided. Always use a silumin box.
In other areas, use a heat-resisting box (T 125 °C) and heat-resisting cables
(T 170 °C). The connection box must be clear of obstacles. When installing the
connection box to zones 2 or 3, refer to the instructions and regulations of
the local energy supplier.
