Sauna room ventilation
Compliments of www.saunasandstuff.com
In a sauna, the air should be changed about 6 times an hour. See
Figure 6.
It is recommended that ventilation openings meet the requirements of UL Specifi cation 875. The minimum opening should be
determined using one of the following formulas:
For R< 31, V ≥ 9 .3
For R ≥ 31, V ≥ 0.3*R
where R = the fl oor area of the room in square feet and
V = the minimum vent size in square inches
ExampleVenting Calculation:
Room is 54 sq.ft.(9 ft. by 6 ft.) 54 is larger than 31.
Multiple 54 x 0.3 = 16.2 sq. in.
Vent size opening should be 4 in x 4 in.
Positioning the inlet vent
Install the inlet vent straight through the wall under the centerline
of the heater.

Removing the Rock Guard
Unscrew the two screws on the side of the heater and lift the
rock guard upwards, see Figure 7. (This is necessary when fi lling
the stone compartment or cleaning the fragrance holder and air
humidifi er).

2. Outlet vent position through the sauna wall.
3. Outlet vent position through the cavity.
4. Outlet vent position via duct.
Positioning the outlet vent
Position the outlet vent
• at the maximum possible distance from the air intake vent,
e.g. diagonally (see Figure 6).
• high on the wall or in the ceiling (see Figure 6).
• so that it vents into the space that the door and air intake
vent open into.
Figure 7: Removing the Rock Guard
Room construction
For safety and reliability, the following rules must be addressed.
• The enclosed WARNING: Reduce the risk of overheating
… warning plate must be mounted on or alongside the door
outside the sauna room at about eye level. Use the supplied
screws.
• The enclosed CAUTION: Reduce the risk of fi re … caution
plate must be mounted on the interior wall above the heater.
Use the supplied screws.
• No permanent locking or latch system is to be used on the
sauna door.
• Acceptable door fi ttings are: magnetic catches, friction catches, spring or gravity loaded closures. The door must always
open outwards.
• No shower may be installed in a sauna room.
• No electrical receptacle shall be installed inside the sauna
room.
• The heater should not be operated without its container properly fi lled with rocks and the rock guard in place.
• If an intercom speaker is installed, it should be away from the
heater and as close to the fl oor as possible.
• If a room light is installed, it should be a surface mounted
bracket type. Wall mounted lights should be about 70” above
the fl oor. Ceiling mounted lights should be of an approved
type with a junction box that is remote to the fi xture itself.
Use only a fi xture that uses A.F. or fi xture type internal wiring.
A 60 watt bulb should provide suffi cient lighting.
• Fire sprinkler systems installed inside any sauna room should
be properly rated for sauna room temperatures.
• Always mount the heater according to these installation
instructions.
The outlet vent must have the same area as the inlet vent.
Ensure that the outlet vent is open.
Mechanical ventilation is not recommended due to the risk of poor
air exchange, which can negatively aff ect the heater temperature
cut-out.

USER GUIDE
GENERAL INFORMATION
Default settings
Using the control panel for the fi rst time:
See instructions supplied with the control panel.
Congratulations on your new sauna heater! Follow this user guide
to get the most from your purchase.
Wet and dry saunas are forms of bathing which originate way
back in history. A hot sauna is best enjoyed at temperatures between 145-190°F.
PRIOR TO USE
The fi rst time you use the heater
Fill the stone compartment
NB: Always use dolerite stones (Manufacure’s
Stones)! "Ordinary" stones may damage the heater.
Do not use ceramic stones. Ceramic stones may
damage the heater. The heater guarantee does not
cover damage caused by ceramic stones.
Fill the stone compartment around the heating elements from the
bottom to the top, to approx. 2” above the top front edge. Do not
press the stones into place. Capacity: Approx. 35 lb of stones.
Place the stones loosely to allow optimum air circulation. The tubular heating elements must not be squeezed together or against
the side.
Sauna stones must:
• tolerate extreme heat and fl uctuations caused by water being
poured on them.
• be cleaned before use.
• must have an uneven surface, so that the water "clings" to
the stone surface and evaporates effi ciently.
• be between 1-1/2” to 2” in size to allow air circulation in the
stone compartment. This will increase the life of the tubular
elements.
Prior to each use
Check the following
Check that:
• there are no foreign objects in the sauna cabin, on or in the
heater.
• the door and any windows to the sauna cabin are closed.
• that the sauna door opens outwards with a little pressure.
NB:
DANGER! Fragrant essences and similar products may ignite, if poured directly onto the
stones.
NOTE! Do not use the sauna cabin for any purpose
other than taking saunas.
Turn on the main power switch
The main power switch is at the bottom of the heater.
Switch it on, if it is not already switched on (see Figure 2).
NB: Never place stones on top of the side air
chambers. This way will obstruct air circulation,
causing the unit to overheat and the cut-out switch
to activate.

Turn on the heater to remove any new paint odors
To remove "new paint odor" from the heater:
Heat the sauna heater for about one hour. The water reservoir
does not need to be working.
A little smoke may appear.

Water reservoir in operation:
The control panel in general
See instructions supplied with the control panel.
Water reservoir
The sauna heater works with and without water in the tank.
When the water reservoir is in use, max. two out of three heater
elements in the stone compartment will be working. The heater
switches automatically between the reservoir and stone compartment, depending on which setting has been set on the control
panel. See the instructions supplied with the control panel.
Filling the water reservoir:
Before starting the heater, fi ll the water reservoir by carefully pouring tap water through the herb grille, see fi g. 3.
1. When in use and if the water level drops below the upper level
sensor, it will continue to operate as normal but a single fi lled-in
drop symbol will show on the Elite control panel display (Pure
control panel shows unlit water drop). Water can be added, and a
steady audio signal will sound when the water level reaches full.
2. When in use and if the water level drops below the safety
sensor, three pulsing audio signals will sound and two empty drop
symbols will show on the Elite control panel display (Pure control
panel shows a fl ashing water drop when the heater is operating).
This indicates that there is insuffi cient water in the reservoir, and
the heater element will automatically switch off .
Other functions
Fragrance holder
DANGER! Never put fragrances in the herb bowl
or water reservoir.
DANGER! Fragrant essences etc. may ignite if
poured directly onto the stones.
Figure 3: Filling the water reservoir.
Note! Never use salt water - can damage the heater
element in the reservoir. It can also cause a build
up of foam which causes the level sensor to detect
a higher water level than actual, and the heater elements can break.
1. An empty reservoir is shown by two empty drop symbols on the
Elite control panel display (Pure control panel shows a fl ashing
drop symbol when the heater is operating). If the reservoir is empty when activating the main switch, three pulsing audio signals will
sound
2. When the water level reaches the safety sensor, a fi lled drop
symbols will shown on the Elite control panel display (Pure control
panel shows an unlit drop symbol). The heater element in the
reservoir can be started.
3. When the water level reaches the upper level sensor, two
fi lled-in drop symbols will show on the Elite control panel display
(Pure control panel shows unlit water drop). A continuous audio
signal will also sound for approx.: 2 secs, indicating that the water
level in the tank is full (in case you do not check the control panel
display during fi lling).
Note! Do not add more water after the audio signal
to avoid the water boiling over and out of the reservoir.
To create a pleasant fragrance in the sauna, pour a few drops of
Tylö Sauna Fragrance into the water in the fragrance holder.
You can also mix a few drops of the sauna fragrance with water in
a sauna bucket and pour the water on fully heated stones. Use a
sauna ladle for pouring water on the hot stones.
Pour max. 1-2 ladles of water at a time, and then wait until the
stones have regained suffi cient heat before pouring fresh water
on the stones again.
Tylö Sauna Fragrance comes in diff erent variants and fragrances.

Air humidifi er
WARNING! Do not confuse the instructions for
the air humidifi er with those for the water reser-
voir.
2
DANGER! Do not pour water into the fragrance
holder once it has been heated up, as this can cause
boiling water to splash on the sauna occupants. Do
not stand or sit in front of the heater while water is
being poured into the fragrance holder, as hot water
can spray out suddenly.
To maintain a comfortable basic level of humidity in the sauna, fi ll
the built-in air humidifi er (see Fig. 4) with water before switching
on the sauna.
Tip: Pour a few drops of diluted sauna fragrance into
the built-in air humidifi er.
EXTERNAL ON/OFF SWITCH (OPTION)
External ON/OFF switch can be installed anywhere outside the
sauna. The switch is momentary pulse or constant activation.
The heater circuit automatically recognises which is used. Heater
status and faults on the door contact can be seen if the switch has
a built-in LED.
See instructions supplied with the control panel.

1. Water reservoir hose.
2. Remove plug
3. Lower hose into a suitable container
Switch off main power switch
CAUTION! The heater’s memory function will be
cancelled if disconnected from the mains for more
than 7 days. The date and time will have to be reprogrammed.
AFTER USE
Empty the reservoir
DANGER! Hot water! Wait until the water has
cooled before completing this step.
To prevent the build-up of limescale and higher salt/mineral levels,
empty the reservoir after each bath. If this is not done and water
is added each time you take a sauna, foam build-up can occur
which can cause the level sensor to detect a higher water level
than actual, with a risk that the heater element will break.
To empty:
1. Release the hose from the hose clip.
2. Hold the hose up and remove the plug.
3. Lower the hose into a suitable container and drain off the
remaining water.
4. Hang the hose on the hose clip.
The main power switch is at the bottom of the heater.
Switch off here when the heater is not to be used for an extended
period (e.g. several weeks).

1. Electrodes
Descaling the water reservoir
Descale the water reservoir as required using Tylö descaling
agent.
How to descale:
1. Remove the herb grille from the herb bowl.
2. Start the steam function (see The section called Use, Page
13) and run until the water boils.
3. Switch off the heater, and wait for about 5 minutes.
4. Mix 2 cups of descaling agent and pour into the water inlet.
5. Leave the descaling agent to work for 1 hour, empty the res-
ervoir and rinse thoroughly.
6. If necessary, repeat the procedure several times until all limescale has been removed.
Cleaning the fragrance holder/air humidifi er and herb bowl
Clean the fragrance holder/air humidifi er and herb bowl as required.
To clean the fragrance holder/air humidifi er and herb bowl:
Lift out the fragrance holder/air humidifi er and herb bowl and
rinse them under running water.
Temperature Safety Switches
The heater's temperature protection devices:
• PCA - The temperature safety on the PCA in the heater is designed to prevent components being damaged by overheating. If
the safety switch is triggered, an error code shows on the control
panel display.
If the overheating switch has activated, the heater cannot be
started again until the temperature has dropped down 68 degrees
(ºF) on the PCA.
• Water reservoir - The temperature safety switch in the reservoir
is designed to protect the heater element from boiling dry. There
is a red reset button under the heater which must be pressed in
(see Fig. 9). If the cut-out has activated, the button will feel stiff
and will 'click' when reset. If the cut-out has not activated and
after resetting, the button will feel springy.
• Heater - The temperature cut-out in the heater protects the components and woodwork in the sauna from overheating. There
is a white reset button on the left side of the heater which must be
pressed in (see Fig. 9). If the heater safety switch has activated,
the button will feel stiff and will ‘click’ when reset.
Information!
When the overheating safety switches activate, always check the
cause of the problem. The life of the elements and PCA can be
adversely eff ected by each overheating. If systems continues to
overheat look at the following: Ventilation defi cient? Room volume? Internal heater fault? Water reservoir not properly cleaned?
Figure 8: Cleaning the fragrance holder/air humidifi er and herb
bowl
Check the stone compartment
Check the stone compartment at least once annually or as many
times per year as the heater is used per week.
Example: If the unit is used 3 times a week, check the stone
compartment 3 times per year.
How to check the stone compartment:
1. Remove all stones from the compartment.
2. Remove any small stones, gravel and lime-scale from the
compartment.
3. Put whole, undamaged stones back. Replace damaged
stones with new ones as required (see Filling the stone compartment, page 13).
