1. Manual for sauna heater

1.1 Check before taking a sauna bath

1. The sauna room is suitable for taking a sauna bath.

2. The door and the window are closed.

3. 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

The main switch of the sauna heater is located in the lower part of the sauna heater, beside the ther-

mostat.

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 thermo-

stat 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 0–3 hour zone, heating elements will turn on and the sauna heater is warm for the selected

period of time.

In the 1–9 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 three hours

unless the timer is turned to the 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. A list of war-

ranty service shops is included in the delivery.

1.3 Infromation for use

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 in-

volved. Children must not be allowed to play with the appliance or to clean and service it without su-

pervision. (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 2,6 Preparing ).

2. Recommended sauna room ventilation

Image 1 Sauna room ventilation

1. Sauna room 3. Electric sauna heater 5. Exhaust flue or channel

2. Washroom 4. Exhaust valve 6. Door to the sauna room

7. A ventilation valve can be installed here to be kept closed while the sauna is heated and during bathing.

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.

2.1 Heating the sauna

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.

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.

2.2 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, over 100 mm to allow good ventilation between the stones. This extends

the useful life of the heating elements.

- 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 8. 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 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.

1. 0 position. The sauna heater is not on.

2. Operating zone 1–3 hours. Set on this zone, the sauna

heater heats up at full power while the sauna thermostat

controls the temperature.

3. Preset zone 1–9 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.

2.3.2 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 ther-

mostat 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:

1. The power is on;

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.

THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS TO THE PREMISES FOR

THE FUTURE USER.

Product Manual Laine STJ

2.6 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 (m3). Volume/input recommendations are

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 m3to the sauna room's volume.

4. Check page 8 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.

2.7 Installation

Image 2 Safety clearances distances, minimum dimensions (mm)

Follow the safety clearance specifications on page 8 when installing the sauna heater.

The sauna heater is a floor-standing model. The base must be solid, because the sauna heater weighs about 75 kg

with stones

The sauna heater is levelled by the adjustable legs.

The sauna heater needs to be fixed directly onto the wall or to the sauna bench module by using the provided metal

rack to make sure the safety distances will be maintained in use.

Walls or ceilings must not be clad with fibre-reinforced plaster board or other light-weight cladding, because they may

cause a fire hazard.

Only a single sauna heater is allowed per sauna room.

2.8 Main connection

The sauna heater must be connected to the mains by a qualified electrician and in compliance with current regulations. Sau-

na 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.

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 inter-

rupter.

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.
