heater StoneS
The main purpose of the stones in the heater unit is to store enough energy to efficiently
vaporize the water thrown on top of the stones to maintain correct humidity in the sauna
room. The stones must be removed at least once a year or every 500 hours which ever
occurs first. All stone crumbles must be removed from the heater unit and replaced with
new ones as described in the heater manual. When placing the stones, recommended to
use cut resistant gloves. The required amount of stones is listed in the manual provided
(See page 30, Technical Data).
note!
Never use the heater without stones as it may cause fire. Use only manufacturer
recommended SaWo-stones. Using unsuitable stones may lead to heating element damage
and will void the warranty. Never use eramic stones or other artificial stones of any type!
loading StoneS into the heater
It is recommended that all stones should be rinsed to remove any stains or dust that can
cause unpleasant odor during the first few times of using the heater. It is important that
the stones are loaded carefully in a way that they do not block air circulation through the
heater. Load the stones to the heater so that the heating elements are not visible from
any angle. Larger stones that won’t fit between the heating elements must not be forced
in place instead they must be completely removed. Small crumble or stone pieces smaller
than 35mm in diameter must not be loaded into the heater because they will block the
air circulation and will cause overheating and possible heating element damage. Load
the stones to the heater so that the heating elements are not visible from any angle. If
heating elements touch each others, it will significantly reduce the life span of heating
element.
note!
Heating element damage due to overheating caused by wrong kind of stones or stones
which were wrongly loaded into the heater is not covered by the factory warranty.
Before the heater is filled with stones, electrician should test that the heater works.
Testing can be done by turning on the heater for a short time without any stones and
verifying that all heating elements are heating up.
