2.3. Heater Output
When the walls and ceiling are covered with panels, and the insulation behind the panels is sufficient to prevent thermal flow into the wall materials, the heater output is defined according to the cubic volume of the sauna. See table 1.
If the sauna has visible uninsulated wall surfaces, such as walls covered with brick, glass block, concrete or tile, each 10 square feet (ca. 1m²) of said wall surface causes thecubicvolumeofthesaunatoincreaseby42 Cu.Ft.(ca. 1.2m3).Theheateroutputisthenselectedaccordingtothe values given in the table.
Because log walls are heated slowly, the cubic volume of a log sauna should be multiplied by 1.5, and the heater output should then be selected on the basis of this information.
2.4. 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 outside.
Inlet ventilation openings shall be located at the bottom of the wall, as close to the floor level as possible.
Outlet ventilation openings shall be located at the top of the wall, as close to the ceiling as bossible, and shall comply with the minimum size requirements for inlet ventilations openings. See fig. 4.
Sauna shall be provided with intended ventilation as required per the local code authorities.
2.5.Hygienic Conditions of the Sauna Room
Good hygienic standards of the sauna room will make bathing a pleasant experience.
The use of sauna seat towels is recommended to prevent sweat from flowing onto the platforms. The towels should be washed after each use. Separate towels should be provided for guests.
It is advisable to vacuum or sweep the floor of the sauna room in connection with cleaning. In addition, the floor may be wiped with a damp cloth.
The sauna room should be thoroughly washed at least every six months. Brush the walls, platforms and floor by using a
Wipe dust and dirt from the heater with a damp cloth.
3.INSTRUCTIONS FOR THE INSTALLATION
3.1.Prior to Installation
•Prior to installing the heater, study the instructions for installation, as well as checking the following points:
•Is the output and type of the heater suitable for
the sauna room?
The cubic volumes given in table 1 should be followed.
•Are there a sufficient number of high quality sauna rocks?
•Is the supply voltage suitable for the heater?
•The location of the heater fulfils the minimum requirements concerning safety distances given
in fig. 5 and table 1.
It is absolutely necessary to ensure that the installation is carried out according to these values.
Neglecting them can cause a risk of fire.
Only one electrical heater may be installed in the sauna room.
