NOTE!
Never use the heater without stones as it may cause fire or damage the heater. In
household use recommended stones are Olivine, olivine diabase or peridot in size less than 10
cm. Stones must be loaded into heater so that there are space between stones for air
circulation.
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 replaced 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. The required amount of stones is also listed in the manual
provided. See page 26 (Technical Data).
Heater Stones
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. Make sure
that the elements don’t get bended or touch each other as a result of the loading by properly
installing the heating element spacer. 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. Use
the addtional heating element separator to make sure that heating elements are in no contact
with each other. Do not place stones inside the heating element holder, but only around and on
top of it. 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.
