1.1 Piling of the Sauna Stones
The sauna stone for an electric heater should be 2-4" in
diameter. The heater stones should be solid blocks of stone
specially intended for use in the heater. Neither light,
porous ceramic "stones" of the same size nor soft
potstones should be used in the heater, because they
may cause the resistance temperature to rise too high as
a result of which the resistance may be broken.
Stone dust should be washed off before piling the stones.
The stones should be piled into the stone compartment
over the grating, between heating elements (resistances)
so that the stones support each other. The weight of the
stones should not lie on the heating elements.
The stones should not be piled too tightly, so that air can
flow through the heater. See Figure 1. The stones should be
fitted loosely, and not wedged between the heating elements.
Very small stones should not be put into the heater at all.
The stones should completely cover the heating elements.
However, they should not form a high pile on the elements.
The stones disintegrate with use. Therefore, they should
be rearranged at least once a year or even more often if the
sauna is in frequent use. At the same time, any pieces of
stones should be removed from the bottom of the heater, and
disintegrated stones should be replaced with new ones.
The warranty does not cover any faults caused by the use
of stoves not recommended by the factory. Neither does the
warranty cover any faults caused by disintegrated or too
small stones blocking the heater ventilation.
No such objects or devices should be placed inside
the heater stone space or near the heater that could
change the amount or direction of the air flowing though
the heater, thus causing the resistance temperature to
rise too high, which may set the wall surfaces on fire!

Instructions for Installation and Use
1.2 Heating of the Sauna
Before switching the heater on always check that there
isn't anything on top of the heater or inside the given
safety distance. See item 1.6 Warnings.
When the heater is switched on for the first time, both the
heater and the stones emit smell. To remove the smell, the
sauna room needs to be efficiently ventilated.
The purpose of the heater is to raise the temperature of the
sauna room and the sauna stones to the required bathing
temperature. If the heater output is suitable for the sauna
room, it will take about an hour for a properly insulated sauna
to reach that temperature. See item 2 "Sauna Room
Construction - General Information." A suitable temperature
for the sauna room is about 149 - 176°F (65 - 80°C).
1.3 Control Unit of Heater
The SMS-100, SMS-125 and SMS-145 model heaters
require a separate control unit to operate the heater. The
control unit should be located outside the sauna room in a dry
place, at an height of approximately 5 ft. The temperature
sensor, by means of which the set temperature is maintained
in the sauna room, must be connected to the control unit. The
temperature sensor and the overheating limiter are located in
the sensor box installed above the heater. The sensor box
should be installed in accordance with the installation
instructions of the control unit model in question.
NOTE:The SMS-100, SMS-125 and SMS-145 model heaters
are controlled with the S170-1 digital sauna control unit. The
SMS-100-3, SMS-125-3 and SMS-145-3 model heaters are
controlled with the S170-3 digital sauna control unit.

1.4 Throwing Water on Heated Stones
The air in the sauna room becomes dry when warmed up.
Therefore, it is necessary to throw water on the heated
stones to reach a suitable level of humidity in the sauna.
The humidity of the air in the sauna room is controlled by
the amount of water thrown on the stones. A correct level of
humidity makes the bather’s skin sweat and makes breathing
easy. By throwing water on the stones with a small ladle, the
bather should feel the effect of air humidity on his skin. Both
too high a temperature and air humidity will give an unpleas-
ant feeling.
Staying in the hot sauna for long periods of time
makes the body temperature rise, which may be danger-
ous.
The maximum volume of the ladle is 0.2 litres. The
amount of water thrown on the stones at a time should
not exceed 0.2 l, because if an excessive amount of water
is poured on the stones, only part of it will evaporate and
the rest may splash as boiling hot water on the bathers.
Never throw water on the stones when there are people
near the heater, because hot steam may burn their skin.
1.4.1. Sauna Water
The water to be thrown on the heated stones
should meet the requirements of clean household
water. The factors essentially affecting the quality
of water include the following:
●Humus content (colour, taste, precipitates);
recommended content less than 12 mg/l.
●Iron content (colour, smell, taste, precipitates);
recommended content less than 0.2 mg/l.
●Hardness – the most important substances are
manganese (Mn) and calcium (Ca);
●Recommended content of manganese 0.05 mg/l,
calcium less than 100 mg/l.
Calcareous water leaves a white, sticky layer on the stones
and metal surfaces of the heater. Calcification of the stones
deteriorates the heating properties.
Ferrous water leaves a rusty layer on the surface of the
heater and elements, and causes corrosion.
The use of humus, chlorinated water and seawater is
forbidden.
Only special perfumes designed for sauna water may
be used. Follow the instructions given on the package.
1.4.2. Temperature and Humidity of the Sauna Room
Both thermometers and hygrometers suitable for use in a
sauna are available. As the effect of steam on people varies,
it is impossible to give an exact, universally applicable bathing
temperature or percentage of moisture. The bather’s own
comfort is the best guide.
The sauna room should be equipped with proper ventilation
to guarantee that the air is rich in oxygen and easy to breath.
Bathing in a sauna is considered a refreshing experience
and good for the health. Bathing cleans and warms your body,
relaxes the muscles, soothes and alleviates anxiety. As a
quiet place, the sauna offers the opportunity to meditate.

3.4. After Installation
3.4.1. Testing of Sauna Heater
1. After sauna heater has been properly wired, according to
appropriate wiring diagram and local codes, turn sauna
breaker on in the main breaker panel. (Note: Electrician
must label “Sauna” breaker.)
2. Turn thermostatic (heat) control to on position (this is
located either on your heater or on your remote wall
control. If you have a wall control, the indicator light will
come on to show that the sauna is heating). Set timer to 10
or 15 minutes.
3. Within 5 minutes, you should be able to feel heat from
heater elements when holding your hand over heater.
4. If the sauna does not heat, refer to troubleshooting
information.
5. It is normal for smoke to appear during the first heating, as
protective element coating needs to burn off. Turn sauna
on for 1 hour before using the first time, to eliminate
smoking.
3.4.2. Troubleshooting
A. If the sauna heater does not operate after initial
installation and wiring:
1. Make sure that a neutral wire has been included. This is
necessary for all heaters except model with built-in
control).
2. Check circuit breaker in contactor to be sure that it has not
been shorted out.
3. Make sure that the current from the control unit to the
heater has been switched on.
4. Check that the desired temperature programmed in the
control panel is higher than the temperature of the sauna.
B. If the sauna has been in operation, but the heater
ceases to operate:
1. Check breaker to make sure it is on.
2. Check that there is on time left in the control panel.
3. Check overheat limiter reset button in heater (reset is
under the heater) to see if it has been released.
4. Call your electrician or service person for further help.
NOTE: A GROUND FAULT INTERRUPTER (GFI) should not
be installed in and does not belong in a sauna. If used, the
breaker will trip, and damage could result.
C. If the sauna heater operates, but the sauna room does
not come up to sauna temperature (149–176 ºF)
1. You must allow at least 30 minutes for sauna heat-up time.
2. Is the sauna thermometer located 6” from ceiling, and is it
above or close to the sauna heater? (This is proper
location for sauna temperature reading.) Thermometer
readings vary with room heights and location. Eg.180 ºF
above sauna heater = 165 on opposite wall = 140 on upper
bench level = 120 on lower bench level = 100 at floor level.

3. Check for proper wire size, amp size, and proper wiring
(according to diagrams and information) also necessary
copper wiring.
4. Check the placement of stones to make sure they are
loosely spaced around elements, to insure good air flow.
Stones packed too tightly will restrict air flow and reduce
heating capacity.
5. Check for heat loss (around or under door, around ceiling
light or fan – we do not recommend ceiling light and a fan
does not belong in the sauna.
6. Is the room properly insulated?
7. Is the ceiling higher than 7’?
8. After checking all the above, remove rocks and check the
heating elements for holes or burned areas. (Only if heater
has been in use for some time.)
CAUTION: Electrician or service person!
1. BEFORE SERVICING HEATER, CONTROL, OR CON-
TACTOR, TURN POWER OFFAT BREAKER!
2. Open junction box to make sure wires are tightly secured
with no loose connections. Heater wire and all connecting
wires should be copper.
3. Check for burned spots or short in wiring of timer or
thermostat.
Sauna heater's warranty on parts are void if the installer or
electrician fails to follow necessary wiring information
provided or fails to follow code for proper wire size, amper-
age, etc.
3.4.3. Overheating Limiter
Each heater is equipped with an overheating limiter which
is a safety device. If an abnormal heating condition should
occur, the heater will automatically shut off, and it will not
come on again until it cools.
To reset the overheating limiter, locate the reset button
(bottom front on wall models, behind junction box at back
bottom of floor-mounted heaters) and push upward until
contactor kicks in. If the reset button continues to trip, contact
a qualified service person. Be sure that a GFI has not been
installed.
1. Use only clean water on sauna stones. DO NOT use spa
or pool water as it will destroy your heater.
2. Clean water should always be used in sauna buckets and
water should be dumped out after every use. Scour
buckets and dippers occasionally when film collects from
usage. Use plastic bucket liner in bucket to prevent water
leakage.
3. Scrub benches with a soft brush, using soap and water or
a mild disinfectant, when needed — about once a week in
commercial saunas, or depending upon sauna usage. For
sanitation, each bather should sit or lie on a towel (this will
prolong bench life).
4. Remove sauna mat and wash waterproof floor with
disinfectant (e.g. Pine Sol) about once a week or as often
as needed. Hose off Super Dek to clean.
5. To maintain beautiful appearance of Sauna heater, remove
water stains by wiping with a damp cloth occasionally.
6. Our heaters require no special maintenance when properly
installed by a qualified electrical contractor. After 1–2 years
of usage, the rocks may need replacing if they have
crumbled or powdered (depending upon sauna usage).
7. We strongly recommend a floor that can be easily cleaned
(concrete, ceramic tile, or a poured type of flooring). When
this is provided, the sauna can be easily cleaned and kept
in a sanitary condition with little effort. A carpet is NOT
recommended for a sauna! A carpet becomes a perfect
breeding ground for bacteria in the moist conditions of a

such as athlete’s foot.
8. In new construction, a floor drain should also be provided,
especially in commercial saunas for sanitary cleaning and
maintenance.
9. Seal wood around glass in door—inside and outside-
with Thompson’s Water Seal to prevent warpage.
10. When sauna wood becomes stained from perspiration, the
wood may be lightly sanded with fine sandpaper to restore
beautiful appearance. We do not recommend stains or
sealers as toxic vapors may appear when heated.
11. The sauna room will heat faster if the higher vent is kept in
a closed position when heating. The lower vent may
always be kept in an open position.
12. Required warning signs should be posted according to the
instructions.
