INSTALLATION

Location of stove in the sauna room

Only one sauna stove must be used in one sauna room. Do not line the walls around the stove

with for instance mineral or other board, since this type of covering may raise the wall

temperature excessively. Do not build an enclosed casing around the stove.

When placing the stove in the sauna room, pay attention to protective distances to flammable

surfaces. These minimum distances have been given in the Table 2 below, and in the Figure 1,

as well as in the type plate of the stove. The stove can be installed to a niche of the wall which

height is min. 1900 mm (Figure 2). The distances are the same for all stoves referred to in this

instruction. If a guard rail is built around the stove the minimum protective distances must be

followed.

Effect of stove

The effect needed for the sauna stove is determined by the volume of the sauna room, when

the walls and ceiling of the sauna room are of wooden panel and insulated enough. If it is used

in the sauna room on surfaces uninsulated wall materials like brick, masonry, concrete, glass

tiles or tiles on, must the volume calculated be added by 1 m³ for each square metre of such

material. Each window square metre also increases the figure by one cubic metre. This final

result is to be compared with the suggested volumes of each sauna stove.

Mounting of stove to the wall

Mount the stove to the wall with the four screws. See the Figure 3. There must be for example a

board as a support structure behind the wall panel where to the fixing screws will firmly be fixed.

Fixing screws that come with the stove

For installing the remote control: 2 pcs screws, countersunk screws Zn 4x30 mm + plastic plugs

For installing the thermostat sensor: 1 pc screw, cylinder top A2 4x50 mm + plastic plug

For installing the cover lists: 25 pcs screws, cylinder top Zn 3x25 mm

For installing the stove: 4 pcs screws, cylinder top Zn 5x30 mm

Connection to electricity supply

All connection work can only be carried out by a licensed and qualified electrician in accordance

with valid local regulations. The sauna stove is connected as semi-stationay connection to the

junction box on the wall of the sauna room. The junction box must be splash-proof and its

height from the floor must be max. 50 cm (Figure 4). As supply cable, use only rubber cable,

type H07RN-F or similar (60245 IEC 66). NOTE! Do not use cables with PVC insulation.

If the supply cables come to the sauna room at the height of over 100 cm from the floor, must

the cables endure loaded minimum temperature of 170 °C (T170). The electric devices installed

at the height of over 100 cm from the floor, must be approved to be used in a temperature of

125 °C (T125).

The connection box of the control unit is located at the back of the stove. The cover of the

connection box is opened for connection. The supply cable of the stove is brought through the

Figure 3

Figure 4

bottom of the control box. The opening is equipped with the draft removal device. There is

reserved own opening also for the control cable of the electrical heating if applicable.

The stove is connected for the voltage of 400 V 3N~ at the factory by the manufacturer. The

voltage of the resistor elements is 230 V. The classification of the connection box is IPX4. The

sauna stove must be properly grounded through the grounding terminal of the stove.

There can be absorbed moisture to the resistor elements of the stove e.g. during the storing.

That might cause leakage current in metering of the insulating resistance. The moisture

disappears from the resistor elements after couple of heating times. Do not connect the electric

supply of the stove through the residual current device.

4 REMOTE CONTROL

MOUNTING OF THE THERMOSTAT SENSOR

The thermostat sensor is mounted to the wall of the sauna room, so that the distance from the ceiling to the upper

edge of the sensor is ca. 30 cm. The minimum distance from the side of the stove to the sensor is 60 cm. The

sensor must not be mounted close to a door or a window. The minimum distance from the possible inlet vent of

fresh air to the sensor is 100 cm. The sensor is fixed to the wall with the screw that comes with the stove. The

sensor is connected to the line connector of the stove according to the order of the colours informed on the side 3.

For finishing the installation comes with the stove a cover list for the wire of the sensor.

MOUNTING OF THE REMOTE CONTROL

The remote control can be mounted in the sauna room. The remote control must be mounted in the sauna room so

that the maximum distance from the floor to the upper edge of the remote control is 100 cm. The minimum distance

from side of the stove to the remote control is 50 cm. The remote control is connected to the line connector of the

stove according to the order of the colours informed on the side 3. The remote control is fixed to the wall with the

screws that come with the stove. The fixing is done as follows:

-find a suitable location for the remote control

-screw the fixing screws to the wall with the paper pattern that comes with the stove (remove the paper pattern after

the screws are fixed)

-screw the screws to the wall so that the tops of the screws remain 3 mm out of surface of the wall

-put the remote control on tops of the screws on the wall so that the tops of the screws go into the holes in back of

the remote control

-pull the remote control downwards, so that the remote control is locked to the tops of the screws

Sauna stove stones

The sauna stove stones must be purposely meant for use in sauna stoves. Stones must endure

well temperature changes and heavy surface disintegration. Suitable sizes of the stones are 5-8

cm in diameter. Misa sauna stove stones, product no. 19211, are peridotite stones (diam. 5-8

cm, 25 kg/box). The use of soap stones in the sauna stove is only permitted in the top stone

layer. The use of the light, same size ceramic stones is forbidden, because they can cause

overheating and breakage of the resistor elements. The stones must be washed before placing

them in the stove.

The stones must be laid with care. Start laying the stones from the corners and sides of the

stone space with larger stones. The resistor elements of the stove must not bend against the

stone space wall or against each other. The stoves must not be laid too tight. There must be left

plenty of air gaps between the stones allowing unobstructed air circulation in the stone space.

Air circulation heats the sauna room air and cools the resistors so that their surface

temperature does not rise excessively. The stone space must be filled up with stones, but there

must not be a mound of stones at the top of the stone space, see Figure 6. The small holes at

the back part of the stove body must be left open, i.e. do not block them with stones. The

cooling air flow discharges through those holes and cools the structure of the stove. The air

resistance in the holes also balances the intensity of the steam flow directed upwards, hence

distributing the steam evenly in the room.

SAUNA ROOM

Materials of walls and ceiling

All the massive wall surface materials (e.g. brick, masonry, concrete, glass tile) store lots of

heat. If it is wanted to be chosen a sauna stove which effect if relatively low, must the walls and

ceiling be sufficiently insulated. The thickness of the insulating wool is 100 mm (min. 50 mm) in

well insulated wall and ceiling structures. For moisture protection can be used e.g. aluminium

paper, which seams are thoroughly taped and which glossy side is laid towards the sauna

room. For surface material is recommended low mass wooden panel boards (thickness ca. 12-

16 mm). Between the damp proofing and the wooden panel boards is left air gap of ca. 10 mm.

Between the upper end of the wall panel boards and the ceiling panel boards is left air gap of

couple of millimetres.

WARNING!

If the stone space ii filled partially

only, a risk of fire is caused.

However, a loosely filled stone

space and a partially filled stone

space are two different things.

Figure 6

If the sauna stove of lower effect is wanted to be chosen, can the ceiling of the sauna room be

built at the lower level. The ceiling is normally at the height of 210-230 cm and the minimum

height of the sauna room is 190 cm.

For the height from the upper bench to the ceiling is recommended max. 110-120 cm.

Air circulation in the sauna room

Correct ventilation in the sauna room guarantees a pleasant sauna experience. If no

mechanical ventilation is used, the inlet air is preferably led to below the sauna stove using a

ca. Ø 5-10 cm pipe which is equipped with an adjusting device. Used air is exhausted through a

discharge vent located at the bottom of the wall opposite the sauna stove. This vent must have

a diameter twice as large as that of the air inlet pipe. If mechanical ventilation is used the inlet

air should be led to above the sauna stove at the height of min. 50 cm upwards from the sauna

stove. Air exhaust vents located on the wall near the ceiling or on the ceiling, potentially

provided with mechanical exhaust, are kept closed during heating and bathing. They are only

used for drying the sauna and for post-ventilation.

Examples for ventilation of the sauna room in Figure 7.

Figure 7

Water

For purpose of throwing water on the heated stones, always use clean water that fulfils the

quality requirements of the water for household. On the quality of the water effects for instance

humus in water: recommended to be less than 12 mg/l, iron contents: recommended to be less

than 0,2 mg/l, hardness: most important substances for that are: manganese (Mn):

recommended to be less than 0,05 mg/l and calcium (Ca) i.e. lime: recommended to be less

than 100 mg/l. Humous water (e.g. lake water) must not be used for throwing water on the

heated stones because of the precipitates that is causes. Use of salty seawater is definitely

forbidden.

USE OF THE STOVE

The electronic control of the stove is equipped with a main switch.

The main switch is located on back of the stove, next to the

openings for the cables. Switch on the control from the main

switch. If the stove is unused for a longer time, the electronics of

the stove can be switched off from the main switch.

off the stove -> can be reset by pressing the reset button in the sensor

-the remote control is not working

-check that the electronics has been switched on from the main switch

-check that the fuses have not been blown

-if there is a break down in the distribution of the electricity during the heating/pre-heating period, stops the

control system the pre-heating/heating period which does not start again without switching on again from

the remote control when the electricity distribution returns back to normal

SERVICE

When needed the stones in the sauna stove must be laid again and changed.

The repairing work of the electric devices can only be carried out by a licensed and qualified

professional electrician.

If the stove is not warming up, check first the following things:

-that the stove has been switched on

-that the time has been set according to the scale where the stove is heating

-that the thermostat has been adjusted to the higher level than the temperature in the

sauna room

-that the fuses have not been blown

-that the temperature limiter has not cut the current

SPARE PARTS

If you ever need spare parts for your sauna stove, please first record the model number of your

sauna stove from the type plate (e.g. 12560DAK), which is needed to know and must be given

when the spare parts are ordered.

Warning !

Never cover the sauna stove. Do not hang anything flammable, such as towels, above or near

the stove, since they may cause a risk of fire.

Electric products can be repaired only by a licensed and qualified electrician.
