1. Quick instructions for use of the sauna heater
1.1. Check before taking a sauna bath
1. The sauna room is suitable for taking a sauna bath.
2. The door and the window are closed.
3. The sauna heater is topped with stones that comply with the manufacturer's recommendations, the heating elements are
covered with stones, and the stones are piled sparsely.
NOTE! Ceramic rocks are not allowed.
A pleasant, smooth sauna bath temperature is about 70 °C degrees.
Rearrange the sauna stones at least once a year and replace any weathered stones. This enhances air circulation between the
stones, which extends the useful life of the heating elements.
If you encounter any problems, please contact the manufacturer's warranty service shop.
For additional information about enjoying a sauna bath, please visit our website at www.helo.fi
1.2. Operation of the sauna heater controls
The main switch is located on the side of the sign at the bottom of the sauna heater.
The sign shows the position of the switch. ( 0 I )
Refer to the specific control panel operating instructions.
2. Information for users
Persons with reduced physical and mental capacity, sensory handicap, or little experience and knowledge about how the device
is operated (e.g. children), should only operate the device while supervised or according to instructions given by the persons in
charge of their safety.
Make sure that children aren't playing with the sauna heater.
2.1. Sauna room
The walls and ceiling of a sauna room should be thermally well insulated. All surfaces that store heat, such as tiled and
plastered surfaces must be insulated. It is recommended to use wooden panel cladding inside the sauna room. If there are heat
storage elements in the sauna room, such as decorative stone, glass etc., note that these elements may extend the pre-heating
period even though the sauna room is otherwise well insulated (see page 5, section 3.1. Preparing for sauna heater installation).
2.2. Recommended sauna room ventilation
Please refer to the ventilation instructions on page10.
2.3. Heating the sauna
Before turning the sauna heater on, make sure the sauna room is suitable for taking a sauna bath. When heated for the first
time, the sauna heater may emit some odour. If you detect any odour while the sauna heater warms up, disconnect the sauna
heater briefly, and air the room. Then you can turn the sauna heater on again. The heating of a sauna should be started roughly
an hour before you plan to take a sauna bath, so that the stones have time to heat up properly and the air warms up evenly in
the sauna room.
Do not put any objects on the sauna heater. Do not dry clothes on the sauna heater or anywhere in its vicinity.
Installation and User Manual HELO CAVA / HELO ROXX DET 3

2.4. Sauna heater stones
Quality stones meet the following requirements:
1. Sauna stones should withstand heat and heat variation caused by vaporisation of the water thrown on the stones.
2. Stones should be rinsed before use in order to avoid odour and dust.
3. Sauna stones should have an uneven surface to supply a larger surface for the water to evaporate from.
4. Sauna stones should be large enough, measuring about 50–80 mm to allow good ventilation between the stones. This
extends the useful life of the heating elements.
5. Sauna stones should be piled sparsely in order to enhance ventilation between the stones. Do not bend the heating
elements together or against the frame.
Rearrange the stones regularly (at least once a year) and replace small and broken stones with new, larger stones.
Stones are piled so that they cover the heating elements. Do not, however, pile a large heap of stones on the heating elements.
For a sufficient amount of stones refer to Table 1 on page 11. Any small stones in the package of stones must not be piled on
the sauna heater.
The warranty does not cover defects resulting from poor ventilation caused by small and tightly packed stones.
Ceramic rocks are not allowed. They may cause damage to the sauna heater that will not be covered by the warranty.
Installation and User Manual HELO CAVA / HELO ROXX DET 4

2.5. If the sauna heater will not heat up
If the sauna heater will not heat up, please check that:
- the power is on;
- the main fuses of the sauna heater are intact;
- is there any error messages on the control panel. In case of an error message on the control panel, please refer to the control
panel instructions.
3. Instructions for the installer
THE PERSON INSTALLING THE SAUNA HEATER SHOULD LEAVE THESE INSTRUCTIONS AT THE PREMISES FOR THE
FUTURE USER.
3.1. Preparing for sauna heater installation
Check the following before installing the sauna heater.
1. The ratio of the heater's input (kW) and the sauna room's volume (m3). Volume recommendations are presented in the table 1
on page 11. The minimum and maximum volumes must not be exceeded.
2. The sauna room height must be a min. of 1900 mm.
3. Uninsulated and masonry stone walls extend the preheating time. Each square metre of plastered ceiling or wall surface adds
1.2 m3to the sauna room's volume.
4. Check page 12 Table 2 for a suitable fuse size (A) and the correct diameter of the power supply cable (mm²) for the sauna
heater in question.
5. Conform to the specified safe clearance around the sauna heater. Please refer to table 1 on page 11.
6. There should be enough room around the sauna heater for maintenance purposes. Also a doorway can be considered as a
maintenance area.
3.2. Installation
Follow the safety clearance specifications on page 11 when installing the sauna heater. A thin panel is not a suitable mounting
base; the mounting base must be reinforced with timber behind the panel. The minimum clearances specified on page 11 must
be followed even if the sauna room wall materials are incombustible.
Walls or ceilings must not be clad with fibre-reinforced plaster board or other light-weight cladding, because they may cause a
fire hazard.
Install the sauna heater so that the sign and the warnings can be read even after the installation.
The control panels are installed outside the sauna room with the exception of the Midi controller which is installed on the wall
beside the sauna heater. Refer to more detailed installation instructions in the installation and operation guide of the control
panel.
Only a single sauna heater is allowed per sauna room
Installation and User Manual HELO CAVA / HELO ROXX DET 5

3.3. Various stages of the installation
3.3.1. Mounting the sauna heater to the wall
With the adjustment legs driven in, the mounting height of the sauna
heater wall mount is 750mm from the floor.
The adjustment legs can be adjusted 15mm in case the floor is inclined.
After the mounting, check that both adjustment legs are evenly against
the floor.
The distance between the holes for the mount in the wall is 240mm.
Parts for wall mounting:
- sauna heater locking wedges (A) 2 pcs
- wall fastening (B) 1 pc
- sheet metal screw 4.2 x 13mm 2 pcs
- build screw 6 x 40mm 2 pcs
Pass the locking wedges (A) through the holes in the heater
so
that the ingoing part is turned upwards.
The wall mount (B) is attached to the wall so that the holes
where the locking wedges are secured to are upwards.
The mount may also be attached directly to the sauna heater.
Mark the locations of the screws on the wall and, if
necessary, drill small holes and mount the sauna
heater then to the wall with the screws provided.
The picture shows how the wall mount should be attached to
the sauna heater. The locking wedges are attached to the
wall mount with the sheet metal screws.

The installation instructions are enclosed in the packaging.

3.3.2. HELO CAVA – Assembly instructions for the heater soapstones
Before the installation of the soapstones the heater has to be fixed to the wall.
See the instructions on page 6.
Take the front soapstones out from the package.
The stone to be placed as the lowest has rounded lower corners. Pass the
stones carefully along the guide. The other (4 pcs) soapstones have even
edges and therefore it does not matter in which order they are placed.
Install the intermediate pieces (8) of the soapstones so that the projection
will always stay on the stone i.e. there will always be an air gap between
the stones.
The metal pieces are placed on each side between each stone (except the
uppermost).
Once the front soapstones have been installed, place the stones meant to
be inside the heater (approx. 30kg). Some stones also have to be placed
on the heating elements.
NOTE! No heater stones should be placed between the first heating
element and the front soapstones. The heater must not be used
without the front soapstones or when the stones have cracks on them.
Image 2 installation of the soapstones
Installation and User Manual HELO CAVA / HELO ROXX DET 7

After installing the sauna rocks, install the metallic supports above them.
The illustration shows the order.
The heater body has both vertical and end limiters which prevent the
movement of the soapstone both vertically and horizontally once they
are installed. Install the metallic supports between the vertical limiters.
The soapstones also remain between the vertical limiters.
End limiter
The illustration shows the installed supports.
The soapstones are installed as follows:
- Install the upper stone first.
- Place as shown in the illustration: first one of the
ends under the edge; push the stone then under
the other edge until it stops in the end limiter.
NOTE!
The stone has to remain behind the vertical limiter.
Image 2,1 installation of the soapstones
Installation and User Manual HELO CAVA / HELO ROXX DET 8

Install the round-edged stone next. Push the other end under the edge
and then push the stone along the support plate against the end limiter.
In the illustration the round edge stone and the soapstone furthest at the
back remain where they are.
The illustration shows both the vertical and horizontal limiters of the
soapstones.
Install the middle stones. The length of the middle stones is 405mm.
Push the stone first under the right edge and then along the support
plate under the left edge against the end plate.
Finally check that the soapstones are between the end limiters and that
the gaps between the stones are equal.

3.4. Recommended sauna room ventilation
Image 3 Recommended sauna room ventilation
1. Sauna room 3. Electric sauna heater 5. Exhaust flue or channel
2. Washroom 4. Exhaust valve 6. Door to the sauna room
7. A ventilation valve can be installed here to be kept closed while the sauna is heated and during bathing.
Inlet vent can be positioned in the A zone. Make sure the incoming fresh air will not interfere with (i.e. cool down) the sauna
heater's thermostat near the ceiling.
The B zone serves as the incoming air zone, if the sauna room isn't fitted with forced ventilation. In this case, the exhaust valve
is installed min 1m higher than the inlet valve.
DO NOT ISTALL INLET VALVE WITHIN ZONE C, IF THE SAUNA HEATER'S CONTROL THERMOSTAT IS LOCATED IN
THE SAME ZONE.
3.5. Connection of the sauna heater to the mains
The sauna heater must be connected to the mains by a qualified electrician and in compliance with current regulations. The
sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66) cables or a corresponding type.
Other output cables (signal lamp, electric heating toggle) must also adhere to these recommendations. Do not use PVC
insulated cable as a connection cable for the sauna heater.
A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control current fuse, the
diameter of all cables must be the same, i.e. in accordance with the front fuse.
The connecting box on the sauna wall should be located within the minimum safety clearance specified for the sauna heater.
The maximum height for the connection box is 500 mm from the floor. See page 12 Image 5 Location for the connecting box.
If the connection box is located at over 500mm distance from the heater, the maximum height is 1000mm from the floor.

Sauna heater insulation resistance:
The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leakage currents. The
moisture will be gone after a few heating sessions. Do not connect the heater power supply through a ground fault interrupter.
However, adhere to the effective electrical safety regulation when installing the sauna heater.
3.6. Electric heating toggle
The electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked 55) for controlling the electric heating toggle. Connector 55 and the heating elements
are simultaneously live (230V).
3.7. Sauna heater safety clearances
NOTE! The thermostat is installed at a distance of 40mm from the ceiling in the middle of the sauna heater.
