THINGS TO CHECK BEFORE INSTALLATION
• Does the output (kW) match the volume (m) 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 m 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
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 in view of installing the electric heater are listed in Table 1.

INSTALLATION
Positioning the heater
• The heater must be positioned in such a way that there is a safe
distance between flammable materials and the external surfaces
of the heater. See Figure.
• In installing the heater, it must be prevented that people could
have physical contact with the heater or that other dangerous
situations could emerge during the heating process.
• STEEL Mini holds approximately 60 kg of stones and STEELholds
approximately 150 kg.
• The input of the power cable is located on the boom 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 SIHFJB 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 1.
6
NB! 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.
• Aach 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.
Fiing the stones
Upon stacking the stones, one should monitor that the heating
elements are not bent and that there is a suicient air circulation
around the heater elements.
• The stones must be washed clean before laying.
• When 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 3–5 cm are suitable for the heater.
• The stones on the external surface of the heater must fully cover
the heating elements. The heating elements must not be visible.
• Using ceramic stones in the STEEL heater is allowed upon the
user’s responsibility.
ATTENTION! Too sparsely filled stone container causes fire hazard!

First-time use of the sauna heater
Before switching the heater on, the insulation resistance might prove
to be lower than the standard. The reason for that is the moisture
seeped into the insulating layer during storage in the warehouse and
transportation.
The moisture evaporates in 1–2 hours of heating the electric heater.
Controlling the heater
All certified control panels may be used in controlling the heater.
The output of the heater must remain in the interval determined by
the control panel’s producer.
You can find the right remote and other accessories from HUUM’s
selection of products.
Guard rails
• It is recommended to construct a guard rail around the heater.
We recommend using materials with low heat capacity and bad
thermal conductivity for the guard rail.
• Upon using flammable materials, it is necessary to leave the
specified minimal safety clearances between the heater and
flammable constructions.
NB! Installing the heater closer to flammable constructions than at the
distance of the minimal required protection belt may cause fire hazard.
Make sure to view our selection of products.

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.
The following sauna wall and ceiling construction is considered
to be suiciently 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;
• a light wooden board that is about 12–16 mm thick has 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 use the heater with a regular output, it would be practical
to bring the ceiling of the sauna lower (min. height of sauna room
2200 mm) so that the volume of the sauna room diminishes. The
ceiling is insulated with an insulation laer 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 heat barrier has to be approved by the fire
inspector. Insulating flues in use is forbidden!
NB! 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.
9
Floor of the sauna room
The heater stones in use crumble due to temperature changes.
The pieces and pebbles breaking away from the heater stones are
washed on the sauna’s floor with the steam-making water. Hot stone
parts may damage plastic flooring under and near the heater.
Heater stone particles and sprays 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 assure a suicient oxygen supply and fresh air, the sauna’s
ventilation must be as eicient 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 heater at least
20 cm above the inlet valve. It is advised to install a ventilation valve at
the upper part of the sauna room for the final ventilation.

WARNING!
• Before turning on the electric heater, always check the sauna
room and 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.
• Ventilating the sauna room incorrectly 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 outward.
• Do not use the sauna for any other purpose than it is meant to be
used.
• Do not install more than one heater in the sauna room.
• Undiluted sauna essences etc. may ignite when poured directly
on the stones.
• Do not leave small children in the sauna unaended.
• 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 in a secure place.
• The product’s warranty guarantee does not extend to heating
elements.
