• The sauna stove must be operated with a suitable external control unit.
• Only one sauna stove with the appropriate heating capacity may be installed in the sauna cabin.(See table)

Connection rating [kW]	cabine size [m3]
3,6 up to approx. 6 m	^3

• The unit is not designed for use in public saunas.
- Caution – danger of burns. The case on the sauna stove and the stones get very hot.
- If it is not installed correctly the unit may cause a fire. Read the complete assembly instructions with due care. Pay particular attention to the dimensions and instructions.
- Only use sauna stones approved for use in saunas. Insert sauna stones loosely; if the stones are inserted too tightly there is a danger of overheating.
- Do not operate the stove without sauna stones.
- Keep children away from the sauna stove. They may suffer burns.
- Seek medical advice about the sauna temperature and how long people with medical problems, infants, children, pensioners and handicapped people may stay in the sauna.
- Do not allow the sauna stove to be used by people who are under the influence of medication, alcohol or drugs.

• Pour small amounts of liquid on to the stones; if you pour too much liquid on to them you may suffer scalds. The quantity of liquid on the stones should not exceed 15g / m^3 of cabin volume.
• Do not use the sauna to dry items, clothing or laundry. They may catch fire.
• Do not place any items on the stove. They may catch fire.
• Do not place any items, apart from the sauna controller's temperature sensor, in the convection current of the stove.
  • Metal surfaces may rust in a damp, saltwater climate.
• The stove may generate cracking noises while it is heating up and while it is operating (metal heating elements and stones expanding)
• Sauna equipment and sauna cabins may only be made of suitable, low resin and untreated materials (for example Norway spruce, poplar or linden).
• The maximum temperature for the wall and ceiling of the sauna cabin is +140°C.
  • Over time the cabin walls will become darker near the sauna stove than in the rest of the cabin; this is normal. Complaints about this will not be accepted.
  • The minimum height of the sauna cabin must be 1.75m (interior height)
• Ventilation openings must be provided in every sauna cabin. The ventilation opening must be on the wall directly below the sauna stove approx. 5-10 cm above floor level. The waste air must be discharged through an opening diagonally opposite the stove in the rear wall between the top and bottom benches. The ventilation openings must not be sealed. The cabin light and its installation must have a splash-proof design and be suitable for an ambient temperature of 140^ . Therefore only an approved sauna light with max. 40W may be installed with the sauna stove.

Installation instructions

Important.

Do not use any floor coverings under the stove if they are made of inflammable material such as wood, plastic, etc. Ceramic tiles are ideal for use in a sauna.

The area under the stove may suffer discoloration, even on non-flammable flooring or joint material.

No compensation will be paid for discoloration or damage to flooring or the sauna walls.

The distance between the rear of the stove and the cabin wall depends on the design (wall mounting).

The stove must be connected to the electricity supply before it is mounted on the wall holder.

The sauna stove is designed for cabin sizes up to 6m ^3 .

Installing the sauna oven

• Mount 4 wall brackets in accordance with Fig. 3.
• Place the sauna stove in front of the air inlet opening. (distance from floor 30cm) Use the supplied wood screws to secure the wall bracket for the sauna stove to the cabin wall. Insert the stone grid and place the sauna stones on top (see the description in „Loading the sauna grid with sauna stones“, section „Cleaning and care“).
• When mounting the sauna stove on the wall, make sure that there is a vertical distance of at least 110cm between the top edge of the sauna stove and the sauna ceiling and a horizontal distance of at least 4cm between the stove and the cabin wall. The distance between the rear of the stove and the cabin wall depends on the design (wall mounting).
• The distance from the stove's safety grille or bench and other combustible materials to the stove must be at least 4 cm. The safety grille height must be the same as the height of the stove at the front.

Dimensions of the sauna stove:
Length: 280 mm
Depth: 370/460 mm
Height: 460 mm

Note:

The control equipment may be destroyed even if it is incorrectly connected only once. The warranty will be voided if the electrical connection is not correct.

Instructions for the electrician

DIN VDE 0100 and Accident Prevention Regulation BGV A2 must be observed for connecting the stove and all electrical systems. An external all-pole disconnecting device with full isolation according to overvoltage category III must be installed.

Important:

Mains connection leads must be flexible cables with polychlorophene sheaths. No connection leads are supplied with the stove. All the cables installed inside the cabin must be capable of withstanding temperatures of at least 140 °C. Heat-resistant silicon cables must be used. The minimum cross-section of the connection cable and the minimum size of the sauna cabin are shown in the table (page 5 Table 1). A connection diagram is affixed to the inside of the duct cover. Please note that for safety reasons live cables are not allowed to be routed visibly along the internal walls of the cabin. In prefabricated sauna cabins the wall element with the air supply opening generally has empty cable conduits or a duct for routing the cable. If your cabin does not have any cable routing preparations, we recommend that you install a connection socket (not supplied) to the outside of the cabin. Drill a hole in the cabin wall near the cable infeed from the stove and the connection socket. Thread the cable through the hole to the external connection socket. All cables must be protected from damage. This can be achieved using installation ducting/piping or using wooden covers.

Position the sauna stones on the stone grid

Sauna stones are a natural product. We recommend that you clean the stones with clean water before placing them on the stove. Do not use stones unless they are designed for use in a sauna. Use a maximum of 12 kg of stones. Important. Position the stones loosely and remove any stones that are too small. If the stones are packed too tightly they will affect the air circulation and will result in the sauna stove and cabin walls overheating and a fire risk. Do not use the stove without stones.

Only use stones that are marked as sauna stones in shops. Warranty claims will not be accepted if stones other than those designed for use in saunas are used or for claims resulting from filling of the stone chambers incorrectly. Turn the stones at least once per year, remove any stones that are too small and remove all stone dust and stone splinters. We recommend that you replace the stones every two years.

Important.

If you cover the stove and fill the stone container incorrectly the unit may cause a fire. Do not use the stove without sauna stones.

Cleaning and care

Switch off the stove and allow it to cool before you clean it. Do not use scouring cleaning products to clean the stove.

Liquids

The sauna stove is suitable for sauna liquids.

Please read the following carefully:

• Only use water that meets the quality requirements for domestic water.
  • Water that contains high levels of lime or iron will leave residue on the stones and metal in the water tank.
• To prevent scalds caused by rising steam whilst pouring liquid over the stones, liquids should always be poured from the side using a ladle.
• Dripping water may cause permanent marks on the cabin floor.
• Pour small amounts of liquid on to the stones; if you pour too much liquid on to them you may suffer scalds.
• Use as much liquid as you are comfortable with, but do not exceed a volume of 15g / m^3 of cabin volume.

• The liquid should be poured straight on to the stones in the stove and must be spread evenly over all the stones.

• If you use liquid concentrates (for example essential oils), follow the instructions for use provided by the manufacturer.
  • Using excessive concentrations of these products may result in explosions.

• Do not use mixtures of alcoholic drinks or other additives not recommended for use in saunas as they pose a risk of fire, explosion and may be harmful.
• The warranty will be voided if you fail to follow these instructions.

Important. Liquids may cause marks on metal surfaces and sauna stones. Sauna liquids with citrus fragrance may cause rust patches as a result of their acid content.

In this case you should only use products in the diluted form specified by the manufacturer.

Troubleshooting

The stove will not heat up

• Have you activated all the necessary switches?
• Has the fuse in the domestic installation tripped?
  • Have you set the temperature controller correctly?
  • Have you pre-set the time switch?
• Defective sauna control unit (sensor breaker, see operating manual for the control unit).
• RCCB trips – see the section entitled "Testing the insulation resistance"

The stove causes "cracking noises"

- The case parts and heating elements expand when the stove is heating up or operating. The heating elements may move the sauna stones and cause noises. Cracking noises are normal and are not grounds for complaint.

• Sauna stones split and cause an odor

• Use only sauna stones recommended by the manufacturer.
  • Sauna stones are too old; replace them.

The cabin does not get hot enough

• The sauna stove is too small
- Excessive temperature loss from the sauna cabin, for example due to poor or lack of sealing.
- Incorrect display on the sauna thermometer. Mount the thermometer higher and at a distance of approx. 3 cm from the sauna wall.
- Have a defective heating element (heating element does not glow) checked and measured by an electrician.
