WARNING
Prolonged exposure to elevated temperatures is capable of inducing
hyperthermia. Hyperthermia occurs when the internal temperature of the
body reaches several degrees above the normal body temperature of
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
SECTION 3: PLACING OF ROCKS (SEE DIAGRAM #10)
For ease of operation, the heater controls may be mounted on the left or
right side. If the controls are relocated, this should be done before
mounting the heater to the wall.
MOVING THE CONTROLS Lay the heater on its back: remove the
control knobs by pulling them straight off (See Item 1 on Diagram 3);
unsnap the plastic hole plugs from the left and right sides of the heater
enclosure. Remove the bottom cover by sliding it towards the back of
the heater about 1 inch and then pulling the middle of the plate towards
the bottom of the heater. The metal plate will flex slightly and come out.
Remove the screws which hold the mounting bracket with the controls,
then carefully move assembly to their new position. Reassemble in the
reverse order using the original hardware. Ensure that no wires are
pulled loose, pinched, kinked, pulled tight or otherwise damaged. Use
the plastic hole plugs to cover the unused control mounting positions.
Reinstall the metal plate on the bottom of the heater.
HANGING THE HEATER Using the template provided, drill four
9/64" holes to fasten the heater to the wall. Install two ¼" x 1 ½" hex
head lag screws (supplied with the heater) into the upper two holes.
Tighten these screws until their heads are about 1/8" from the wall
surface. The screws must be threaded through the wall into a framing
member or backing board to support the heater weight. Hang the heater
on the two upper screws.
Locate the two ¼" x 1" hex head lag screws (supplied with the heater)
then install them into the two lower mounting holes. Tighten to lock the
heater in place.
See Diagram 1 & 2 for the heater location details and the necessary
clearances to combustible materials.
The rocks supplied with the heater 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. Carefully place
the rocks loosely so that the air can circulate through the heater. Packing
the rocks too tightly may cause the heater high limit switch to trip. The
rocks must fully cover the heating elements. Attach the guard with the
screws provided.
Fire sprinkler systems used
inside any sauna room should
be properly rated for sauna
room temperatures.
Do not pour chlorinated pool
or spa water on heater.
Excessive water use on heater
may cause damage and void
warranty.

SECTION 7: HIGH LIMIT CONTROL (RESET BUTTON)
SECTION 8: HOW TO TAKE A SAUNA
The sauna heater has a built-in high limit control, which automatically
turns off the heater if the temperature inside in the sauna room rises to
an abnormally high level.
To restart the heater, let the heater cool and turn the timer down to zero
(off), then push the reset button on the bottom of the heater (See Item 3
on Diagram 2). If the high limit continually shuts off the heater, refer
to Section 13.
• When taking a sauna, allow time to relax completely.
• Remove clothing and jewelry...if required, wear a towel loosely.
• 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.
• 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 take care to keep clear of the steam as it rises off the
rocks.
• Do not smoke, exercise or drink alcoholic beverages in the sauna
room.
• Do not pour chlorinated pool or spa water on the heater or corrosion
damage may result.

WARNING
SECTION 10: ROOM CONSTRUCTION
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 fixtures get very hot
during operation. Locate
light fixture where it will not
be a burn hazard.
The "CAUTION" and
"WARNING" placards must be
mounted in accordance with
Section 9.
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 fittings 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 fire … caution plate
must be mounted on the interior wall above the heater.
• The heater should not be operated without its container properly filled
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 floor 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 floor. Ceiling
mounted lights should be of an approved type with a junction box that is
remote to the fixture itself. Use only a fixture that uses A.F. or fixture
type internal wiring. A 60 watt bulb should provide sufficient 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.
SECTION 11: 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
Specification 875. The minimum opening should be determined using
one of the following formulas:
For R<31, V³9.3
For R³31, V³0.3R
where R = the floor area of the room in square feet and
V = the minimum vent size in square inches

INSTALLATION AND OPERATING INSTRUCTIONS Page 10
DIAGRAM 11: ROOM TEMPERATURES
Notes:
Temperatures vary in a sauna room by height
and distance from heater.
Ventilation will help reduce it but will not
eliminate temperature variations.
The hottest part of the room is always at the
ceiling directly above the sauna heater and
should not exceed 194°F (90°C).
Air temperature will be 15°F to 25°F lower
on the opposite side of the room from the
heater close to the ceiling.
The temperatures in the elevated view are
general numbers. Each sauna room is differ-
ent due to construction variations and venti-
lation.
