98.6°F. The symptoms of hyperthermia include an increase in the normal
temperature of the body, dizziness, lethargy, drowsiness, and fainting. The
effects of the hyperthermia include failure to perceive heat, failure to
recognize the need to exit the room, unawareness of impending hazard,
fetal damage in pregnant women, physical inability to exit the room and
unconsciousness.
WARNING
The use of alcohol, drugs, or medication is capable of greatly increasing
the risk of fatal hyperthermia.

SECTION 2: MOUNTING OF SAUNA HEATER
HANGING THE HEATER This heater can be installed in a corner or on a at wall.
The heater brackets are factory attached for a at wall installation. To mount the
heater in the corner reverses the brackets.
Using the template provided, drill four 9/64" holes to fasten the heater to the wall.
The screws must be threaded through the wall into a framing member or backing
board to support the heater weight. Install the two ¼" x 1 ½" hex head lag screws
(supplied with the heater) into the upper two holes. Install the two ¼" x 1" hex
head lag screws (supplied with the heater) into the lower two holes. Tighten these
screws until their heads are about 1/8" from the wall surface. Hang the heater on
the four screws. Tighten to lock the heater in place. See Diagram 1 for the heater
location details and the necessary clearances to combustible materials. Refer to
Diagram 1 for drawings and Diagram 4 for pictures.
SECTION 3: PLACING OF ROCKS (SEE DIAGRAMS #10 and 11)
The rocks supplied have been chosen to provide the best heater performance. Use of any
other type of rock may void the heaters warranty. Never operate the heater without rocks
in place! Rinse the rocks with water before placing in the heater.
Install the BWT (Bio Water Technique) tank between the two heating elements. The BWT
tank rests on the top of the elements and aligns with slot in the back heat shield (See
Diagram 11). Place the cover on the tank followed by the fragrance diffuser cup on top.
Start inserting rocks into the heater in even layers so that the heating elements remain as
vertical and evenly spaced as possible. Continue to randomly drop rocks into the heater
until you are even with the top of the heating coils. Add one more loose layer to cover up
the elements and closed portion of the BWT tank. (Do Not Cover Up the round fragrance
diffuser on top of the BWT!) The rocks must fully cover the heating elements. Attach the
rock guard with the screws provided. See Diagram #10 & 11 for rock placement.
Packing the rocks too tightly may cause the heater high limit switch to trip or the room to
heat slow.
SECTION 4: ELECTRICAL HOOK-UP
Electrical installation must be made by a licensed electrician in accordance with the
National Electrical Code and local regulations.
- NOTE: A GFCI (Ground Fault Interrupt Circuit) device is not required by ETL. A GFCI may

• Remove clothing and jewelry...if required, wear a towel loosely.
• Some sauna bathers enjoy the soothing effect of steam by splashing water on the
heated sauna rocks. Use only one dipper full (approx. ½ cup) at a time and keep clear
of the steam as it rises off the rocks.
• This heater has a BWT provided and must be installed in the heater.
• Water in the BWT will add a continuous humidity to the sauna room. Additional water
can be poured onto the hot rocks at any time to boost the steam level.
• Fill tank with approximately 2 cups of fresh tap water when heater is turned on (never
use water from a pool or spa!)
• Heater can operate with BWT tank empty if user does not want constant steam.
• You may add fragrance oils to the BWT if desired.
• Do not pour chlorinated pool or spa water on the heater or corrosion damage may
result.
• After 10 minutes or when perspiration begins, leave sauna and relax in dressing area...
follow with a cool shower.
• Cooling time should equal time spent in sauna. Enter sauna room again and stay 5 or
10 minutes.
• Repeat the cycle 2 or 3 times; end with a brisk shower...rinse in cool water.
• Dress when completely dry and perspiration has stopped.
• Do not smoke, exercise or drink alcoholic beverages in the sauna room.

SECTION 10: WARNING PLACARDS
Three metal placards are included in the Installation Instruction Envelope
packaged with every Sauna Heater. The CAUTION placard must be attached
to the interior wall of the sauna room directly above the heater where it is
visible to the bather. The French and English WARNING placards must be
attached to the door outside of the sauna room.
WARNING
The "CAUTION" and
"WARNING" placards must be
mounted in accordance with
Section 10.
SECTION 11: ROOM CONSTRUCTION
For safety and reliability, the following rules must be addressed.
• No permanent locking or latch system is to be used on the sauna door.
• Acceptable door 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 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.
• The enclosed CAUTION: Reduce the risk of re … caution plate must be
mounted on the interior wall above the heater.
• The heater should not be operated without its container properly 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 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 oor. Ceiling
mounted lights should be of an approved type with a junction box that is
remote to the xture itself.
• Fire sprinkler systems installed inside any sauna room should be
properly rated for sauna room temperatures.
• Always install the heater according to these installation instructions.
For safety purpose sauna
door must open out and not
lock.
Never use a wood stain, seal
or preservative on the inside
of your sauna room.
Light xtures get very hot
during operation. Locate
light xture where it will not
be a burn hazard.

INSTALLATION AND OPERATING INSTRUCTIONS
Page 11
SECTION 12: VENTILATION
VENTILATION In a sauna, the air should be changed about 6 times an hour. This can be achieved by making a vent
opening (fresh air inlet) in the sauna wall directly below the heater. The air outlet must be lower than the upper benches,
as far as possible from the heater and about two feet higher than the fresh air inlet vent, See Diagram 9. It is
recommended that ventilation openings meet the requirements of UL Specication 875. The minimum opening should
be determined using one of the following formulas:
For R< 31, V ³ 9.3, For R ³ 31, V ³ 0.3R
where R = the oor area of the room in square feet and
V = the minimum vent size in square inches
SECTION 13: BWT (Bio Water Technique) Technology
The world sauna trend is moving to the higher humidity and lower temperatures. Many nd it easier to breathe, the skin
feels warm, and the humidity helps induce a sweat. This system will increase the humidity in the room allowing the air
temperature to be lower, and still feel hot.
BWT technology provides the ability to increase humidity levels in the sauna room while the heater is warming up and
during the sauna session. The continuous soft boil of water during the sauna session increases the humidity in the room
to provide a consistent feel. Additional water can be added to the rocks to provide an additional spike of humidity as
needed.
How to use BWT: Allow heater to warm up for approximately 20 minutes and add water into the tank through the side of
fragrance diffuser with slots. Add approximately 2 cups of fresh water into the tank. Do Not Use Pool or Spa Water.
Fragrance oils can be placed in the side of the fragrance diffuser without the slots. Avoid adding fragrances directly into
the water of the BWT. The oils may cause the water to foam and maybe difcult to remove the scent from the tank.
BWT tank and sleeve should always be installed in heater with rocks. Water in the tank is optional and not required if
preference is lower humidity.
SECTION 14: MAINTENANCE
The sauna, like a bathroom, should be kept clean and odor free.
Towels or mats should always be used on benches and oor as perspiration otherwise penetrates the soft wood.
Air out the sauna often by keeping the door and vents open when the sauna is not in use. Saunas that are in daily use
should be washed down at least once a week to keep them clean and the air fresh. Duckboard should be removed from
the sauna, the sauna oor mopped and dried in a conventional manner, and the duckboard thoroughly scrubbed and dried
before returning to the sauna room. The sauna heater should be wiped down occasionally with a damp cloth to remove
lint and dust. The rocks should be removed once a year for cleaning and small or crumbled rocks replaced.
To clean and remove perspiration stains, use soap or detergent in warm water, best applied with a scrub brush. Badly
soiled surfaces may require sanding. Sand paper wrapped around a wooden block works well.
Benches and supporting structure must be inspected annually for potential deterioration due to age, dry rot or abuse. Any
boards with signs of deteriorations should be replaced immediately to avoid possible injury.
BWT will accumulate hard-water scale inside the tank as the water is evaporated over time. The water scale will not
immediately affect performance. It is recommended to remove the tank from the heater and clean it when you notice a
heavy accumulation of minerals or when the rocks are changed. Simply tap on the sides of the tank to loosen the scale
and then dump into a waste basket. If stubborn scale accumulation remains, you may use any commercially available
de-scaling product to remove built-up hard water scale. Follow up with a fresh water rinse before putting BWT back into
the heater.
