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 also listed in the manual provided. See page 26
NOTE!
Never use the heater without stones as it may cause fire. Use only manufacturer
recommended stones. Using unsuitable stones may lead to heating element damage and will void
the warranty. Never use ceramic 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 odour 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. 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.
