Important information about sauna stones

50 kg is a suitable amount. The amount of stones varies, depending on the type of stone.
Only stones with a diameter of 2-4″ (5–10 cm) are allowed.
The stone surface may be rounded. The use of stones with a cleavage surface is not allowed.
Suitable stone materials are peridotite, olivine diabase and olivine.
Ceramic ‘stones’ and soft soapstone are not allowed. They do not absorb enough heat as the heater is being used. Soft stones may crumble and block the air vents. This may break the heating elements and cause the product to behave unlike it was designed.
Rinse any stone dust off the stones before placing them in the heater.

How placing the stones, observe the following

Start with the biggest stones, placing them at the bottom and sides. This ensures sufﬁcient air ventilation and forms a steady base for the stone space.
Place the stones closely against the steel grid, and loosely at the top. Make sure the heating elements are not visible between the stones. A dense layer will prevent direct heat radiation from overheating materials around the heater. Placing stones loosely in the middle will allow air to ﬂow through the heater, heating the sauna and sauna stones well.
Place stones one by one. Do not drop them in the stone space.
Before using the heater for the ﬁrst time, make sure that the stones cannot fall off.
We recommended that you keep some extra stones in store to replace broken ones or to add any if the stone level becomes lower over time.

Do not place any items or devices in the stone space or its vicinity that can change the amount or direction of air ﬂowing through the heater.
If a heating element is not surrounded by stones, it can heat materials dangerously hot, even beyond the heater’s safety distances. Make sure that the heating elements are not visible beyond the stones. As the user, you are responsible for ensuring that the stone space is properly maintained throughout the heater’s life cycle.

Maintenance
Due to large variation in temperature, the sauna stones disintegrate in use. Rearrange the stones at least once a year or even more often if the sauna is in frequent use. Replace any disintegrated stones with new ones. By doing this, the heating capability of the heater stays optimal and the risk of overheating is avoided.
Check occasionally whether the stone level has become lower. Make sure that the heating elements do not become visible over time. The stone level is likely to become lower in about two months after the stones have been placed.

Piling of the Sauna Stones

HARVIA-SP60-6kW-Spirit-Heater-imge-14 NOTE! Make sure that the heater stones do not block the downward movement of the safety device. Before using the heater test the safety function by pressing the back of the safety device. You will hear a soft ‘click’ sound when the safety function is activated.

HARVIA-SP60-6kW-Spirit-Heater-imge-15 Safety function

Heater Fence

It is necessary for safety and should be constructed of softwood to match sauna interior. See > Image 2. Safety distances for clearances from sauna heater. Fence should be attached to wall and should not be placed higher than top line of the heater

Electrical connections

The heater may only be connected to the electrical network in accordance with the current regulations by an authorised, professional electrician.

Image 8. Electrical Connections
The wiring diagrams are included in the control unit’s installation instruction.
Interconnecting cord conductor from Control Unit Assembly to Electric Sauna Heater to have minimum 8 AWG. Listed strain relief to be installed on Electric Sauna Heater.
Further instructions concerning exceptional installations can be obtained from local electrical authorities.

Remove heater from carton and place in proper location in sauna room. Observe proper clearances > Image 2. Safety distances
See applicable wiring diagram for heater model (See control unit manual for detailed instructions how to connect the heater and the control unit). Heater must be permanently installed by using seal tight conduit between the heater and the wall of the sauna room (pigtails or plugs are not allowed in the sauna room). Wiring must be done by a licensed electrician, who must follow wiring diagram provided and adhere to local codes. Use proper AWG rat-ed wire size and use copper wire suitable for 194 °F (90 °C) within sauna walls. Use grounding terminals provided in sauna heater and control unit to properly ground the equipment as per NEC and local codes.
. Inside the heater box there are two signs. Please place the metal ”CAUTION” sign on the interior wall of the sauna room directly above the heater in a visible place (screws and nails included). Place the metal ”WARNING” sign outside, on the door of the sauna room. ”MAINTENANCE INSTRUCTIONS” are at the end of this manual.

Electric Heater Insulation Resistance
When performing the ﬁnal inspection of the electrical installations, a “leakage” may be detected when measuring the heater’s insulation resistance. The reason for this is that the insulating material of the heating elements has absorbed moisture from the air (storage, transport). After operating the heater for a few times, the moisture will be removed from the heating elements.

Do not connect the power feed for the heater through the RCD (residual current device)/GFI (Ground Fault Interrupter)!

Resetting the Overheat Protector
If the temperature of the sauna room becomes dangerously high, the overheat protector will permanently cut off the supply of the heater. The overheating protectors can be reset after the heater has cooled down. Please check that the stones are piled properly and the sensor is installed according the installation instructions. See the operating Instructions of the selected control unit model.

The reason for overheating must be resolved before resetting the overheat protector!

SAUNA ROOM

See WARNINGS AND NOTES!
See TECHNICAL DATA!

Insulation and Wall Materials of the Sauna Room

In an electrically heated sauna, all the massive wall surfaces which store plenty of heat (such as bricks, glass blocks, plaster etc.), must be sufﬁciently insulated in order to keep the heater output at a reasonably low level.

A wall and ceiling construction can be considered to have efﬁcient thermal insulation if

the thickness of carefully ﬁtted insulating wool inside the structure is 4” (100 mm) minimum 2” (50 mm).
the moisture protection consists of e.g. aluminium paper with tightly taped edges. The paper must be ﬁtted so that the glossy side is towards the inside of the sauna.
there is a 1/4” (10 mm) vent gap between the moisture protection and panel boards (recommendation).
the inside is covered by 1/2” – 5/8” (12–16 mm) thick panelling.
there is a vent gap of a few millimetres at the top of the wall covering at the edge of the ceiling panelling.

When aiming at a reasonable heater output, it may be advisable to lower the ceiling of the sauna (minimum height 82,7” (2100 mm)). As a result, the volume of the sauna is decreased, and a smaller heater output may be sufﬁcient. The ceiling can be lowered so that the ceiling joists are ﬁxed at a suitable height. The spaces between the joists are insulated (minimum insulation 4” (100 mm)) and surfaced as described above. Because heat goes upwards, a maximum distance of 47” (1200 mm) is recommended between the bench and ceiling.

NOTE! The protection of the walls or ceiling with heat protection, such as mineral board ﬁtted directly on the wall or ceiling, may cause the temperature of the wall and ceiling materials to rise dangerously high.

ROOM CONSTRUCTION – GENERAL INFORMATION

FRAMING| 2” x 4” (50 x 100 mm) any suitable wood material, 16” (406 mm) o.c.
CEILING HEIGHT| No higher than 7’6” (2300 mm).
INSULATION| R11 Fiberglas with foil back in walls and ceiling, foil facing into room.
DRYWALL| See local codes. Is not required in most residences. See local codes for commercial. If drywall is used apply 1” x 2” (25 x 50 mm) nailers so that wall

and ceiling boards can be attached to solid wood.

PANELING| Use kiln-dried softwood (with moisture content not

exceeding 11 %).

BENCHES| Use matching softwood. Fasten from bottom to

prevent burning of bathers.

DOOR| Must open out and should not have locking or latching system. Types of door

fastenings that may be used are magnetic catches, friction catches, spring- loaded or gravity loaded door closers, and the like.

ROOM LIGHT| Should be a vapor proof, wall mounted type, with rough- in box mounted flush with inside paneling. It should be mounted 6’’ (150 mm) from ceiling, not directly over the sauna heater, and not over upper benches. It could be installed under benches. Light bulb should not exceed recommended watts of the light manufacturer.

NOTE! Receptacles OR PLUGS are not allowed in a Sauna room. If a speaker is installed in a Sauna room, it should not be installed higher than 3’ (914 mm) from ﬂoor, away from the Sauna heater (consult manufacturer for ratings).

Blackening of the Sauna Walls

It is perfectly normal for the wooden surfaces of the sauna room to blacken in time. The blackening may be accelerated by

sunlight
heat from the heater
protective agents on the walls (protective agents have a poor heat resistance level)
ﬁne particles disintegrating from the sauna stones which rise with the air ﬂow.

Sauna Room Floor
Due to a large variation in temperature, the sauna stones disintegrate in use. Small pieces of stone are washed down on the sauna room ﬂoor along with the water thrown on the rocks. To prevent aesthetic damage only dark joint grouts and ﬂoor coverings made of rock materials should be used underneath and near the heater.

Heater Output

When the walls and ceiling are covered with panels and insulation behind the panels is adequate, the heater output is deﬁned according to the volume of the sauna. Non-insulated walls (brick, glass block, glass, concrete, tile, etc.) increase the need for heater output. Add 1,2 m³ to the volume of the sauna for each non-insulated wall square meter. For example, a 10 m³ sauna room with a glass door equals the output requirement of about a 12 m³ sauna room. Because log walls are heated slowly, the cubic volume of a log sauna should be multiplied by 1.5, and the heater output should then be selected on the basis of this information. Choose the correct heater output > Technical data

Sauna room ventilation
Note! Do not place the supply air vent so that the air ﬂow cools the temperature sensor

The air in the sauna room should change six times per hour.
If mechanical ventilation is used, air supply vent should be placed above the heater.
If natural ventilation is used, air supply vent should be placed under or next to the heater. The diameter of the supply air pipe must be 50–100 mm.
Exhaust air vent (Ø 100 – 200 mm). Place the exhaust air vent near the ﬂoor, as far away from the heater as possible. The diameter of the exhaust air pipe should be twice the diameter of the supply air pipe.
Optional vent for drying (closed during heating and bathing). The sauna can also be dried by leaving the door open after bathing.
If the exhaust air vent is in the washroom (Ø 100 – 200 mm), the gap underneath the sauna door must be at least 100 mm. Mechanical exhaust ventilation is mandatory.

Sauna Room Hygiene **

**

Good hygienic standards of the sauna room will make bathing a pleasant experience.

The use of sauna seat towels is recommended to prevent sweat from ﬂowing onto the platforms. The towels should be washed after each use. Separate towels should be provided for guests.
It is advisable to vacuum or sweep the ﬂoor of the sauna room. The ﬂoor may be wiped with a damp cloth.
The sauna room should be thoroughly washed at least every six months. Brush the walls, platforms and ﬂoor by using a scrubbing-brush and sauna cleanser. Then rinse the saunaroom by using clean household water.
Remove lime stains from the heater using a 10% citric acid solution and rinse.
Wipe dust and dirt from the heater with a damp cloth.

OPERATING INSTRUCTIONS

See WARNINGS AND NOTES
!See TECHNICAL DATA!

Heating of the Sauna
When operating the heater for the ﬁrst time, both the heater and the stones emit smell. To remove the smell, the sauna room needs to be efﬁciently ventilated. If the heater output is suitable for the sauna room, it will take about an hour for a properly insulated sauna to reach the required bathing temperature. The sauna stones normally reach the bathing temperature at the same time as the sauna room. A suitable temperature for the sauna room is about 149–176 °F (65–80 °C).

Using the Heater

Before switching the heater on always check that no objects have been placed on top of the heater or inside the given safety distance.
Always inspect the sauna room before restarting the timer.
Heaters are controlled using a separate control unit. See the instructions for use of the selected control unit model.

Throwing Water on Heated Stones
The air in the sauna room becomes dry when warmed up. Therefore, it is necessary to throw water on the heated stones to reach a suitable level of humidity in the sauna. The effect of heat and steam on people varies – by experimenting, you can ﬁnd the levels of temperature and humidity that suit you best. Aim water only on the stones.

The maximum volume of the ladle is 0.2 litres. If an excessive amount of water is poured on the stones, only part of it will evaporate and the rest may splash as boiling hot water on the bathers. Never throw water on the stones when there are people near the heater, because hot steam may burn their skin.

Water quality requirements
The water to be thrown on the heated stones should meet the requirements of clean household water. Only special aromas designed for sauna water may be used. Follow the instructions given on the package.

Water properties	Effect	Recommendation
Humus concentration	Colour, taste, precipitates	<12 mg/l
Iron concentration	Colour, odour, taste, precipitates	<0,2 mg/l
Manganese (Mn) concentration	Colour, odour, taste, precipitates	<0,10 mg/l

Hardness: most important substances are

magnesium (Mg) and lime, i.e. calcium (Ca)

Instructions for Bathing

See WARNINGS AND NOTES!

Begin by washing yourself.
Stay in the sauna for as long as you feel comfortable.
Forget all your troubles and relax.
According to established sauna conventions, you must not disturb other bathers by speaking in a loud voice.
Do not force other bathers from the sauna by throwing excessive amounts of water on the stones.
Cool your skin down as necessary. If you are in good health, you can have a swim if a swimming place or pool is available.
Wash yourself after bathing.
Rest for a while and let your pulse go back to normal. Have a drink of fresh water or a soft drink to bring your ﬂuid balance back to normal

Troubleshooting

All service operations must be done by professional licensed maintenance personnel

The heater does not heat up.

Check that the breakers to the heater are in good condition.
Check that the connection cable is connected.
Check that the control panel shows a higher ﬁgure than the temperature of the sauna.
Check that the overheat protectors have not gone off.
Check that the breaker is switched on. Also, breaker should be correct size.

The sauna room heats slowly. Water thrown on the sauna stones cools down the stones quickly

Check that the breakers to the heater are in good condition.
Check that all heating elements glow when the heater is on.
Turn the temperature to a higher setting.
Check that the heater output is sufﬁcient.
Check that the sauna room ventilation has been arranged correctly.

The sauna room heats quickly, but the temperature of the stones remain insufﬁcient. Water thrown on the stones runs through.

Turn the temperature to a lower setting.
Check that the heater output is not too high.
Check that the sauna room ventilation has been arranged correctly.

Panel or other material near the heater blackens quickly.

Check that the requirements for safety distances are fulﬁlled.
Check that no heating elements can be seen behind the stones. If heating elements can be seen, rearrange the stones so that the heating elements are covered completely.
Also see section > Blackening of the Sauna Walls

The heater emits smell.

See section > Heating of the Sauna
A hot heater may emphasize odours mixed in the air that are not, however, caused by the sauna or the heater. Examples: paint, glue, oil, seasoning.

The heater makes noise.

Occasional bangs are most likely caused by stones cracking due to heat.
The thermal expansion of heater parts can cause noise when the heater warms up.

Maintenance Instructions

Use only clean water on sauna stones. Do not use spa or pool water as it will destroy your heater.
Clean water should always be used in sauna buckets and water should be dumped out after every use. Scour buckets and dippers occasionally when ﬁlm collects from usage. Use plastic bucket liner in bucket to prevent water leakage.
Scrub benches with a soft brush, using soap and water or a mild disinfectant, when needed— about once a week in commercial saunas, or depending upon sauna usage. For sanitation, each bather should sit or lie on a towel (this will prolong bench life).
Remove possible removable ﬂooring and wash waterproof ﬂoor with disinfectant about once a week or as often as needed. Hose off removable ﬂooring to clean.
To maintain beautiful appearance of sauna heater, remove water stains by wiping with a damp cloth occasionally.
Our heaters require no special maintenance when properly installed by a qualiﬁed electrical contractor. Rocks may need replacing if they have crumbled or powdered (depending upon sauna usage).
We strongly recommend a ﬂoor that can be easily cleaned (concrete, ceramic tile, or a poured type of ﬂooring). When this is provided, the sauna can be easily cleaned and kept in a sanitary condition with little effort. A carpet is NOT rec-ommended for a sauna! A carpet becomes a perfect breeding ground for bacteria in the moist conditions of a sauna; and a carpet promotes the spread of foot diseases such as athlete’s foot. For the same reasons, wooden duckboard should not be used for ﬂooring.
In new construction, a ﬂoor drain should also be provided, especially in commercial saunas for sanitary cleaning and maintenance.
Seal wood around glass door—inside and outside—with waterprooﬁng wood protect or to prevent warpage.
When sauna wood becomes stained from perspiration, the wood may be lightly sanded with ﬁne sandpaper to restore beautiful appearance. We do not recommend stains or sealers as toxic vapors may appear whenheated. However, 2 coats of waterprooﬁng wood protector may be used on the woodbenches in a commercial sauna, so that the wood may be more easily cleaned and kept sanitary — the wood will not absorb perspiration.
The sauna room will heat faster if the higher vent is kept in a closed position when heating. The lower vent may always be kept in an open position.
Required warning signs should be posted according to the instructions.
