WARNING
SECTION 10: WARNING PLACARDS
SECTION 11: 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.
Secure the two metal placards at eye level with the screws that 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
WARNING placard must be attached to the outside of the door of the sauna
room.
The "CAUTION" and
"WARNING" placards must be
mounted in accordance with
Section 10.
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.

INSTALLATION AND OPERATING INSTRUCTIONS
314 SKLF 17 A
SECTION 12: VENTILATION
SECTION 13: MAINTENANCE
VENTILATION Ventilation shall be provided 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 8.
The minimum opening should be determined using one of the following formulas:
For R
<
31, V
≥
9.4
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
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 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 floor 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 deterioration should be replaced immediately to avoid possible injury.
