Product Usage Instructions

1. Instructions for Use (EN)

1.1. Piling of the Sauna Stones:

• Wash the sauna stones before use.
• Place the stones in the stone compartment, over the grating, between the heating elements.
• Avoid piling the stones too high on the elements as it may cause the resistance temperature to rise too high and break the resistance.
• Avoid using stones that are too small or that form a high pile on the elements.
• With use, the stones may disintegrate, so they should be rearranged at least once a year or more often for frequent sauna use.
• Remove any disintegrated stones from the bottom of the heater and replace them with new ones.

1.2. Heating of the Sauna:

• Before switching the heater on, ensure that there is nothing on top of the heater or inside the given safety distance. Refer to item 1.6 for warnings.
• When the heater is switched on for the first time, both the heater and the stones may emit a smell. Efficiently ventilate the sauna room to remove the smell.
• Choose a heater capacity that suits the size of the sauna room to ensure an enjoyable bathing experience.

IMPORTANT! This manual must be left with the owner, manager, or operator of the Sauna after it is used by the electrician

Purpose of the electric heater:
The KG-heaters are designed for the heating of large saunas to bathing temperature. It is forbidden to use the heater for any other purposes. Please read the user’s instructions carefully before using the heater.

NOTE! These instructions for installation and use are intended for the owner or the person in charge of the sauna, as well as for the electrician in charge of the electrical installation of the heater .

The overheat protector of the device can go off also at temperatures below -5˚C / 23˚F (storage, transport, environment). Before installation take the device to the warm environment. The overheat protector can be reset when the temperature of the device is approx 18˚C / 64˚F. The overheat protector must be reset before using the device. See the user manual > Overheating Limiter

INSTRUCTIONS FOR USE

Piling of the Sauna Stones

The sauna stones for an electric heater should be 2–4” (4–8 cm) in diameter. The heater stones should be solid blocks of stone specially intended for use in the heater. Neither light, porous ceramic “stones“ of the same size nor soft potstones should be used in the heater, because they may cause the resistance temperature to rise too high as a result of which the resistance may be broken. Stone dust should be washed off before piling the stones. The stones should be piled into the stone compartment over the grating, between the heating elements (resistances) so that the stones support each other. The weight of the stones should not lie on the heating elements. The stones should not be piled too tightly so that air can flow through the heater. See fig. 1. The stones should be fitted loosely, and not wedged between the heating elements. Very small stones should not be put into the heater at all. The stones should completely cover the heating elements. However, they should not form a high pile on the elements. The stones disintegrate with use. Therefore, they should be rearranged at least once a year or even more often if the sauna is in frequent use. At the same time, any pieces of stones should be removed from the bottom of the heater, and disintegrated stones should be replaced with new ones. The guarantee does not cover any faults caused by the use of stones not recommended by the plant. Neither does the guarantee cover any faults caused by disintegrated or too small stones blocking the heater ventilation. No such objects or devices should be placed inside the heater stone space or near the heater that could change the amount or direction of the air flowing through the heater, thus causing the resistance temperature to rise too high, which may set the wall surfaces on fire!

Heating of the Sauna
Before switching the heater on always check that there isn’t anything on top of the heater or inside the given safety distance. See item 1.6.

Warnings

When the heater is switched on for the first time, both the heater and the stones emit a smell. To remove the smell, the sauna room needs to be efficiently ventilated. The purpose of the heater is to raise the temperature of the sauna room and the sauna stones to the required bathing temperature. If the heater output is suitable for the sauna room, it will take about an hour for a properly insulated sauna to reach that temperature. See item 2. ”Sauna Room Construction – General Information”. A suitable temperature for the sauna room is about 149– 176 °F (65–80 °C).

The sauna stones normally reach the required bathing temperature at the same time as the sauna room. If the heater capacity is too big, the air in the sauna will heat very quickly, whereas the temperature of the stones may remain insufficient; consequently, the water thrown on the stones will run through. On the other hand, if the heater capacity is too low for the sauna room, the room will heat slowly and, by throwing water on the stones, the bather may try to raise the temperature of the sauna. However, the water will only cool down the stones quickly, and after a while the sauna will not be warm enough and the heater will not be able to provide enough heat. To make bathing enjoyable, the heater capacity should be carefully chosen to suit the size of the sauna room.

Control Unit of Heater

The KG model heaters require a separate control unit to operate the heater. The control unit should be located outside the sauna room in a dry place, at an altitude of approximately 5 ft (1500 mm). The temperature sensor, using which the set temperature is maintained in the sauna room, should be connected to the control unit. The temperature sensor and the overheating limiter are located in the sensor box installed above the heater. The sensor box should be installed by the installation instructions of the control unit model in question.

The KG model heaters can be controlled with the Harvia Griffin control unit.

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 humidity of the air in the sauna room is controlled by the amount of water thrown on the stones. A correct level of humidity makes the bather’s skin sweat and makes breathing easy. By throwing water on the stones with a small ladle, the bather should feel the effect of air humidity on his skin. Both too high a temperature and air humidity will give an unpleasant feeling. Staying in the hot sauna for long periods makes the body temperature rise, which may be dangerous. The maximum volume of the ladle is 0.2 liters. The amount of water thrown on the stones at a time should not exceed 0.2 l, because if an excessive amount of water is poured on the stones, only part of it will evaporate and the rest may splash as boiling water on the bathers. Never throw water on the stones when there are people near the heater, because hot steam may burn their skin.

Sauna Water

• The water to be thrown on the heated stones should meet the requirements of clean household water.
• Calcareous water leaves a white, sticky layer on the stones and metal surfaces of the heater. Calcification of the stones deteriorates the heating properties.
• Ferrous water leaves a rusty layer on the surface of the heater and elements and causes corrosion.
• The use of humous, chlorinated water and seawater is forbidden.
• Only special perfumes designed for sauna water may be used. Follow the instructions given on the package.

Temperature and Humidity of the Sauna Room

Both thermometers and hygrometers suitable for use in a sauna are As the effect of steam on people varies, it is impossible to give an exact, universally applicable bathing temperature or per- centage of moisture. The bather’s comfort is the best guide. The sauna room should be equipped with proper ventilation to guarantee that the air is rich in oxygen and easy to breathe. Bathing in a sauna is considered a refreshing experience and good for health. Bathing cleans and warms your body, relaxes the muscles, and soothes and alleviates oppression. As a quiet place, the sauna offers the opportunity to meditate.

2. Turn thermostatic (heat) control to on position  (this is located either on your heater or on yourremote wall control. If you have a wall control, the indicator light will come on to show that the sauna is heating). Set timer to 10 or 15 minutes.
3. Within 5 minutes, you should be able to feel heat from heater elements when holding your hand over heater.
4. If the sauna does not heat, refer to troubleshooting information.
5. It is normal for smoke to appear during the first heating, as protective element coating needs to burn off. Turn sauna on for 1 hour before using the first time, to eliminate smoking.

Troubleshooting

1. If the sauna heater does not operate after initial installation and wiring:
2. Check circuit breaker in contactor to be sure that it has not been shorted
3. Make sure that the current from the control unit to the heater has been switched
4. Check that the desired temperature programmed in the control panel is higher than the temperature of the sauna.

If the sauna has been in operation, but the heater ceases to operate:

1. Check breaker to make sure it is
2. Check that there is on time left in the control
3. Check overheat limiter reset button in heater (reset is under the heater) to see if it has been
4. Call your electrician or service person for further

NOTE! A GROUND FAULT INTERRUPTER (GFI) should not be installed in and does not belong in a sauna. If used, the breaker will trip, and damage could result.

1. If the sauna heater operates, but the sauna room does not come up to sauna temperature 160– 185 °F (70–85 °C)
2. You must allow at least 30 minutes for sauna heat-up Is Sauna thermometer located 6” (150 mm) from ceiling, and is it above or close to Sauna heater? (This is proper location for Sauna temperature ) Thermometer readings vary with room heights and location. Eg. 180 °F (82 °C) above Sauna heater = 165 °F (74 °C) on opposite wall = 140 °F (60 °C) on upper bench level = 120 °F (49 °C) on lower bench level = 100 °F (38 °C) at floor level.
3. Check for proper wire size, amp size, and proper wiring (according to diagrams and information) also necessary copper
4. Check the placement of stones to make sure they are loosely spaced around elements, to ensure good air flow. Stones packed too tightly will restrict air flow and reduce heating capacity.
5. Check for heat loss (around or under door, around ceiling light or fan – we do not recommend ceiling light and a fan does not belong in the
6. Is the room properly insulated?
7. Is the ceiling higher than 7’ (2100 mm)?
8. After checking all the above, remove rocks and check the heating elements for holes or burned (Only if heater has been in use for some time.)

Caution! An electrician or service person!

1. BEFORE SERVICING HEATER, CONTROL, OR CONTACTOR, TURN POWER OFF AT BREAKER!
2. Open junction box to make sure wires are tightly secured with no loose Heater wire and all connecting wires should be copper.
3. Check for burned spots or short in wiring of timer or

The sauna heater’s warranty on parts is void if installer/electrician fails to follow necessary wiring information provided or fails to follow code for proper wire size, amperage, etc.

Overheating Limiter

Each heater is equipped with an overheating limiter which is a safety device. If an abnormal heating condition should occur, the heater will automatically shut off, and it will not come on again until it cools. To reset the overheating limiter, locate the reset button (bottom front on wall models, behind junction box at back bottom of floor-mounted heaters) and push upward until contactor kicks in. If the reset button continues to trip, contact a qualified service person. Be sure that a GFI has not been installed. The overheat protector of the device can go off also at temperatures below -5˚C / 23˚F (storage, transport, environment). Before installation take the device to the warm environ- ment. The overheat protector can be reset when the temperature of the device is approx 18˚C / 64˚F. The overheat protector must be reset before using the device.
