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 hyper-
thermia include an increase in the normal tem-
perature of the body, dizziness, lethargy, drowsi-
ness, and fainting. The effects of the hyper-
thermia include failure to perceive heat, failure to
recognize the need to exit the room, unaware-
ness of impending hazard, fetal damage in preg-
nant 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.

Installation and Operating Instructions
Section 2: Mounting of Sauna Heater
HANGING THE HEATER Using the template provided, drill
four 9/64" holes to fasten the heater to the wall. Install two
1/4" x 1 1/2" 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 back-
ing board to support the heater weight. Hang the heater on
the two upper screws. Locate the two 1/4" 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 for the heater location details and the
necessary clearances to combustible materials.

Installation and Operating Instructions
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 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, V≥9.3
For R≥31, V≥0.3R
Where R = the floor area of the room in square feet and
V = the minimum vent size in square inches
Section 13: Maintenance
The sauna, like a bathroom, should be kept clean and odor
free.
Towels or mats should always be used on benches and floor
as perspiration otherwise penetrates the soft wood.
Air out the sauna often by keeping the door and vents open
when the sauna is not un 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 floor mopped and dried in a conven-
tional 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 deter-
gent 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 annu-
ally for potential deterioration due to age, dry rot or abuse.
Any boards with signs of deteriorations should be replaced
immediately to avoid possible injury.
