SECTION 2: MOUNTING OF SAUNA HEATER

• NOTE: Complete electrical connections and test the heater prior to this step.

Attach wall bracket to any of the mounting holes located on either side of the spine on the rear of the heater shroud (reference diagram 4). Slide heater into position, according todimensions shown in Diagram 1 and mark locations for the two mounting screws. Slide heater forward and screw two 1/4” x 1″ lag bolts into sauna wall at locations marked earlier, leaving approximately 1/8” of bolt shoulder exposed so bracket can easily slide over bolt heads. Re- locate heater into position with key-holes of bracket locking onto lag bolts. Adjust the leveling feet to ensure that the heater is vertical. Use a level on two sides of heater to verify plumb.

It mounting heater in center of room, use same procedure described above but locate
mounting bracket so that it can attach to the bench framing that surrounds the heater.

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 second and third heating elements resting on the top of the elements. (See diagram 11) The BWT tank has slots in the outer flange that will align with the element loops. Install the BWT cover and the round herb cup.

Start inserting rocks into the heater in even layers so that the 3 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 top of the BWT. (Do Not Cover Up the round herb cub on top of the BWT!) The rocks must fully cover the heating elements. Attach the 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.

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 be installed if required by local codes but will nuisance trip during use of the product.
• CAUTION: Loose wire connections can cause heat damage to wires, terminal blocks and other components and may void the warranty.

Remove the screws from the left and right sides of the electrical box. Remove the painted trim piece from the front of the box. Route the feed wires through the holes provided in the bottom of the heater and connect the wires to the terminal block. To determine the correct wire size, refer to Diagram 2. Use copper supply wire only, suitable for minimum 90 degrees C. The heater must be grounded! See Diagram 6 for proper connections.

SECTION 5: TEMPERATURE SENSOR

Feed the “low voltage” sensor wire from the sensor to the sauna heater location. Sensor wire must be routed completely separate (as per low voltage electrical wiring codes) from any wiring carrying over 50 volts. It may be necessary to drill holes to string the wire through the studs or ceiling joists. Route the wire to bottom of the heater and connect to the sensor connection. Mount sensor to finished wall 3″ from the ceiling directly above the heater using two (2) screws (provided) as shown in diagrams 1, 3 & 5.

If mounting heater in the middle of your sauna room, locate the temperature sensor on the ceiling above the heater at a point directly above one outer edge of the sauna heater shroud. See Diagram 1.

SECTION 9: HOW TO TAKE A SAUNA

• When taking a sauna, allow time to relax completely.
• 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. ¥z 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 of the sauna room.

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 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.
• 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.
• Minimum of R12 insulation in 16” on center 2×4 stud walls.
• Recommended minimum flooring thickness of 5/8”

WARNING

The “CAUTION” and “WARNING” placards must be mounted in accordance with Section 10.

WARNING

REDUCE THE RISK OF OVERHEATING

• it immediately if uncomic table, dizzy, or sleepy. Staying 0o long ina sauna is capable of causing overeating.
• Supervise chidden al ll ices * Check with a doctor before use if pregnant, in poor health, or under medical care
• Breathing heated air in conjunction wih consumption of alcohol, drugs, or mediation is cashable of causing Unconsciousness,

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 Specification 875. The minimum opening should be determined using one of the following formulas:
For R<31, V=93, For R>31, V=03R
where R = the floor 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 find 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 difficult 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

Inspect sauna room at the end of each day the room to ensure the control and system is off. 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 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 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.

DIAGRAM 12: ROOM TEMPERATURES

Non-Typical Ceiling Height

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 125°F heater and should not exceed 194°

Air temperature will be 15°F to 25°F lower on the opposite side of the room

The temperatures in the elevated view are general numbers. Each sauna room is different due to construction variations and ventilation.
