Mounting on Wall

When fixing, follow the directions in Table 1 and the diagrams. The attachment is by means of the screws accompanying the heater. Ensure fixing behind the heater is adequate to support the heater – i.e. cross struts in sauna paneling.

• NOTE!: Reinforce the panel behind the heater with an extra board before mounting the heater on the wall.
• NOTE!: There must be enough of working space in front of the heater control switch.
• The heater can be installed in a recess of a minimum height of 1900 mm (see Fig. 2).
• Only one heater per sauna may be installed.
• IMPORTANT : Protecting walls or ceilings with a light material that is fixed to the surface of the wall or ceiling may lead to a dangerous rise in temperature in the wall or ceiling.

Safety Rail

• We recommend if a safety rail is installed around the heater, follow the directions given in the fig. 3.

Controls and use of the heater

• The KIP45, KIP60, KIP80, and KIP90 heaters are equipped with a timer and a thermostat on the lower part of the heater.
• The KIP45E, KIP60E, KIP80E, and KIP90E heaters must be equipped with a separate control unit which must be installed in a dry area outside of the sauna room.
• Before you switch the heater on check always that there aren’t any things over the heater or in the near distance of the heater.

Repositioning of Thermostat and Timer

(KIP45, KIP60, KIP80, KIP90) Normally the thermostat and timer are located on the front of the heater (Fig. 3), but if desired they may be moved to the right or left side of the heater. Such repositioning should only be carried out by qualified electrician.

1. Turn the heater upside down and detach the base plate.
2. Remove the timer (1) and thermostat (2)knobs by pulling outwards.
3. Remove the two holding screws from the timer and thermostat attachment plate.
4. Remove the cover plate from the side you have chosen.
5. Replace it with the attachment plate, complete with the timer and thermostat.
6. Push the knobs into place.
7. Attach the cover plate to the front of the heater.
8. Check the timer and thermostat connections and air spaces.
9. Re-attach the heater base plate.

Mains Connection

Due to thermal embrittlement, the use of PVC-insulated wire as the connection cable of the heater is forbidden.

The heater may only be connected to the electrical network in accordance with the current regulations by an authorized, professional electrician. The heater is semistationarily connected to the junction box on the sauna wall. The connection cable must be of rubber cable type H07RN-F or its equivalent. In the lower part of the heater, there is a permanently installed control unit (KIP45–KIP90). In addition to a mains connector, the control center is equipped with extra connectors which enable the following additional connections:

• A. an indicator light above the steam room (see the connection diagram). Cross-section of the connection cable (see Table 1).
  

• B. Locking of electrical heating with the heater (see connection diagram). The control cable of the electrical heating is connected directly to the junction box, and from there to the terminal strip by a rubber cable with the thickness of a connection cable.

  • NOTE! The heater provides a voltage control (230V) from the P and M connectors.
  • The KIP-E models require separate control centre C90/C150 (C150VKK).

Installation of the control unit (C90, C150) and sensors (KIP45E–KIP90E)

• Install the control unit in a dry place outside the sauna room at a height of about 170 cm. The control unit includes detailed instructions for fastening the unit on the wall.
• Install the temperature sensor on the wall of the sauna room above the heater. It should be installed on the lateral center line of the heater, 100 mm down-wards from the ceiling. See fig. 5.

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. Thereason for this is that the insulating material of the heating resistors has absorbed moisture from theair (storage transport). After operating the heater for a few times, the moisture will be removed from the resistors.
• Do not connect the power feed for the heater through the RCD (residual current device)!

Piling of the Sauna Stones

• Sauna heater stones are significant in terms of the unit’s safety. In order for the warranty to remain valid, the user is responsible for proper maintenance of the stone space in accordance with the specifications and instructions.

Important information on suitable sauna stones:

• Suitable sauna stone materials are peridotite, olivine diabase, olivine and vulcanite.
• Only use cleavage surface and/or rounded stones for your sauna heater.
• If the heating elements of an electric sauna heater are in contact with the stones, rounded stones may only be used in the outer layers of the stone space, so that they do not come into contact with the heating elements.
• Ceramic stones and decorative stones may only be used if they have been approved by the manufacturer and are used according to the their instructions.
• Note that decorative stones are only suitable on the top layer of the stone space. Decorative stones must be placed loosely to ensure sufficient air circulation. Place any decorative stones so that they do not touch the heating elements of an electric sauna heater. If you have a woodburning stove, make sure the stones do not touch the stove’s hot inner frame.
• The warranty does not cover any defects that have been caused by the use of decorative stones or by sauna stones not recommended by the manufacturer.
• The sauna stones for an electric heater should be 5–10 cm in diameter.
• 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. 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.
• 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!

Sauna Water

• The water to be thrown on the heated stones should meet the requirements of clean household water (Table 2. Water properties).
• Only special perfumes designed for sauna water may be used. Follow the instructions given on the package.

Use (KIP45–KIP90)

• Temperature control : The desired sauna temperature is set by turning the knob on the heater temperature control. The sauna will heat up to the required temperature within about one hour, depending on the size, construction, and thermal insulation of the sauna. The thermostat will keep the sauna at the set temperature.
• The heater thermostat also protects the heating elements against overheating. If the stones are packed too tightly air will not circulate properly inside the unit. The thermostat will cut the power off to prevent overheating, with the consequense that the sauna will heat up abnormally slowly

Temperature limiting: If for some reason the wooden components of the sauna become abnormally hot, the temperature limit cut-out will switch the heater completely. When the temperature has reached a normal level, the limit cut-out can be manually reset using the button located next to the heater thermostat knob. (See figure 1).

Timer (KIP45-KIP90)

The heater is switched on by using the timer switch.

The timer has two scales: the first one (with larger figures) is the ”instantly on” section; that is, the heater is on for a selected period of time (0–4 hours). The other section is the so-called” pre-set section” (1–8 hours), which is used to start the heater after a certain time. The heater starts when the timer has turned the switch back to the ”instantly on” section, that is, at number four (4). After this, the heater will be on for about 4 hours, unless the switch is turned to zero before that. At zero (0), the supply to the elements is cut off and the heater is switched off.

Example 1. You want to go jogging and have a sauna bath after that. The estimated duration of your run is 5 hours. Turn the timer clockwise over the scale 0–4 to the pre-set section (scale 1–8) at number 4.
The timer will start, and after four hours, the heater will come on. Because it takes about one hour for the sauna to be heated, it will be warm and ready for bathing after about 5 hours, that is, when you come back from your run.

Example 2. If you want to bathe ”immediately” and thus do not want to use the pre-set timing, the timer must be set to the desired point in the section 0–4.

Then, the heater will be switched immediately on and the sauna will be ready for bathing after about one hour.
Switch the heater off immediately after bathing and check that the sauna stones are dry. Sometimes it may be advisable to leave the heater on for a while to let the wooden parts of the sauna dry properly.

NOTE! It is absolutely necessary to check that the timer has cut off the supply of the elements after the set time

Troubleshooting (KIP45–90)

If the heater does not heat, check the following points:

• the electricity has been switched on
• the thermostat shows a higher figure than the temperature of the sauna.
• the fuses to the heater are in good condition.
• the temperature guard has not gone off. The timer sound is heard but the elements are not heated.
• the timer has been switched to a section where the heater should be heated (0–4).

Insulation and Wall Materials of the Sauna Room In an electrically heated sauna, all the massive wall surfaces that 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 house is 100 mm (minimum 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 10 mm vent gap between the moisture protection and panel boards (recommendation)
• The inside is covered by 12–16 mm thick panelling
• There is a vent gap of a few millimeters at the top of the wall covering at the edge of the ceiling paneling

When aiming at a reasonable heater output, it may be advisable to lower the ceiling of the sauna (normally 2100–2300 mm, minimum height 1900 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 100 mm) and surfaced as described above.
Because heat goes upwards, a maximum distance of 1100–1200 mm is recommended between the bench and ceiling.

• NOTE! Consult fire-extinguishing authorities to find out which part of the fireproof wall may be insulated. Do not insulate air chimneys.
• 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.

Blackening of the sauna walls

Wooden material in a sauna, such as panels, blackens with age. The blackening process is sped up by sunlight and the heat from the heater. If the wall surfaces have been processed with protective panel agents, the blackening of the surface of the wall above the heater can be seen quite quickly depending on the protective agent used. The blackening is due to the fact that the protective agents have less resistance to heat than unprocessed wood do. This has been proven in practical tests. The micronic mineral aggregate that crumbles from the stones on the heater may blacken the wall surface near the heater. When following the manufacturer’s approved guidelines in the installation of the sauna heater, the heater will not heat up enough to endanger the flammable material in the sauna room. The maximum temperature allowed in the wall and ceiling surfaces of the sauna room is +140 degrees Celsius. Sauna heaters equipped with CE signs meet all of the regulations for sauna installations. Proper authorities monitor that the regulations are being followed.

Ventilation of the Sauna Room

Sufficient ventilation is extremely important for the sauna. The air in the sauna room should be changed six times per hour. The fresh air pipe should come directly from the outside. According to the newest research results, the pipe should be located at a minimum height of 50 cm above the heater. The pipe diameter should be about 5–10 cm. Exhaust air should be led from the lower part of the sauna directly into the air chimney, or, by using an exhaust pipe starting near the floor level, into a vent in the upper part of the sauna. Exhaust air can also be led out through an exhaust air vent in the washing room through a 5 cm opening under the sauna door. The exhaust air of the sauna room should be taken from as far from the heater as possible but near the floor level. The crosscut area of the exhaust air vent should be twice that of the supply air pipe. For the above-mentioned system, mechanical ventilation is necessary. If the heater is mounted in a ready-made sauna, the instructions of the sauna manufacturer should be followed when arranging ventilation.
The series of pictures shows examples of ventilation systems for a sauna room. See fig. 7.
