THINGS TO CHECK BEFORE INSTALLATION
• Does the output (kW) match the volume (m3) of the sauna room?
See Table 1.
• In case there are any uninsulated brick, tile or glass walls in the
sauna room, an additional volume of 1.5 m³ should be added to the
sauna room for each such square meter of the wall.
• The suitable output of the heater will be determined based on that
volume according to Table 1.
• The producer’s warranty guarantee is invalid if the heater and
sauna room have been dimensioned incorrectly!
• Minimal safe distances between the sauna room’s ceiling and walls
to consider in installing the electric heater are listed in Table 2.
INSTALLATION
Positioning the heater
• The heater must be positioned in such a way that there is a safe
distance between flammable materials and the heater.
• The heater must be installed in a way that prevents people
from having physical contact with the heater or that dangerous
situations could emerge during the heating process.
• The heater holds approximately 250 kg of stones.
• The inputs of the power cable are on the bottom cover of the
heater.

Connecting the heater to the power supply
• Only a certified electrician is allowed to connect the heater to the
power supply.
• A rubber insulated HO7RN-F cable or an equivalent cable must be
used as the connection cable.
• It is recommended to connect the unit to the mains without an
earth-leakage circuit breaker.
• The maximum current intensity in the cross-sectional area of the
cable and circuit breaker are listed in Table 2.
Attention! It is forbidden to use a non-heat-resistant cable with PVC
isolation as the power cable. The joint box must be waterproof and it
must be located up to 50 cm from the floor.

• Open the cover of the heater’s electrical box.
• Attach the power cable on the terminal block according to the
circuit diagram.
• Close the cover.
• Fix the cable on the output with a cable strap.
Fitting the stones
• Make sure that the heating elements are notbent during the process.
• There must be sufficient air circulation around the heater elements.
• Stack the stones sparsely between the heating elements. If the
stones have been stacked too close to each other, the heating
elements may overheat (= shorter useful life) and slow the heating
of the sauna.
• Stones with a diameter of 8–16 cm are suitable for the heater.
• The stones on the external surface of the heater must be stacked
close to one another. The heating elements must not be visible.
• Using ceramic stones in the HIVE heater is allowed at the user’s
responsibility.
ATTENTION! IF THE STONE CONTAINER IS FILLED TOO SPARSELY, IT
POSES A FIRE HAZARD!

Before switching the heater on, the insulation resistance might prove
to be lower than the standard. The reason for that is the moisture that
seeped into the insulating layer during storage in the warehouse and
transportation.
The moisture evaporates after the electric heater has been heated for
1–2 hours.
CONTROLLING THE HEATER
All certified control panels with thermal control may be used in cont-
rolling the heater. The output of the heater must remain in the interval
determined by the control panel’s producer.
GUARD RAILS
• It is recommended to construct a guard rail around the heater. We
recommend using materials with low heat capacity and bad ther-
mal conductivity for the guard rail.
• Upon using flammable materials, it is necessary to leave the speci-
fied minimal safety clearances between the heater and flammable
constructions.
ATTENTION! IF THE HEATER IS INSTALLED CLOSER TO FLAMMABLE
CONSTRUCTIONS THAN AT THE DISTANCE OF THE MINIMAL REQUIRED
PROTECTION BELT IT MAY CAUSE A FIRE HAZARD!
SAUNA ROOM
Wall materials and insulating the sauna room
In a sauna with electric heating, all massive heat accumulating wall
surfaces (brick, glass brick, rendering etc.) must be insulated to use the
electric heater with a regular output.
8
The sauna wall and ceiling construction is considered to be
sufficiently insulated:
• a carefully installed insulation wool layer of 100 mm (min. 50 mm);
• the construction is damp proofed with taped aluminium paper or
other reflective material;
• there is a 10 mm air gap between the damp protection and boarding
• light wooden boards with about a 12–16 mm thickness have been
used for interior finishing;
• there is an air gap of at least 5 mm on the edge of the ceiling panels
at the upper part of the wall panelling.
In order to optimise the use of the heater, it would be practical to bring
the ceiling of the sauna room lower (regular 2,100–2,300, min. height of
sauna room 1,900 mm) so that the volume of the sauna room diminishes.
The ceiling should be insulated with an insulation layer at least 100 mm
thick and boarded according to the method described above. Wood
should be used to cover internal surfaces; an exception may be made
for heat resistant walls in the vicinity of the heater.
ATTENTION! Insulating the warm masonry wall has to be approved by
a fire inspector. It is prohibited to insulate flues that are in use!
ATTENTION! Covering the walls or floor with light protective material,
for example, mineral tiles that are installed directly on the surface of
the walls or ceiling might cause the dangerous overheating of the wall
or ceiling material.

Floor of the sauna room
The heater stones in use crumble due to temperature changes. The
pieces breaking away from the heater stones and pebbles are washed on
the sauna floor with the steam-making water. Pieces of hot stone may
damage plastic flooring under and near the heater. Heater stone par-
ticles and spray from the steam-making water (e.g., with iron content)
may absorb into the light joints of a tile floor. In order to avoid aesthetic
damage (caused by the reasons mentioned above), ceramic tiles and
dark joint filler should be used under and around the heater.
Ventilation of the sauna
• In order to guarantee a sufficient supply of oxygen and fresh air, the
sauna’s ventilation must be as efficient as possible. It is advisable to
direct the fresh air into the sauna room from above the heater stones.
• As an alternative, the fresh air may be directed in from under the heater.
• The air inlet must be equipped with an adjustable valve.
• The exhaust valve must be installed in the opposite wall from the
inlet valve at least 20 cm above the height of the inlet valve.
• It is advised to install a ventilation valve at the upper part of the
sauna room for the final ventilation.

WARNING!
• Always check sauna room and heater before turning on the heater.
• The heater may be used only when it has been correctly filled with stones.
• Do not cover the heater—this causes fire hazard.
• Do not touch a working heater, it causes burns.
• Incorrect ventilation of the sauna room may dry the wood too much
and cause a fire hazard in the sauna.
• Only tap water may be used for making steam.
• Never make steam by using a water hose.
• There must always be at least 5 cm of fireproof heat insulation
under the boarding.
• Sauna doors must always open outwards.
• Do not use the sauna for a purpose it is not intended for.
• Do not install more than one heater into the sauna room.
• Undiluted sauna essences etc. may ignite when poured directly
onto the stones.
• Do not leave small children unattended in the sauna.
• Sudden cooling after staying in the steam room is not recommended
for people with poor health. Consult a doctor.
• Enjoy the sauna as long as it is comfortable for you.
• Keep this information at a safe place.
• The product’s warranty guarantee does not extend to heating elements.
