Heater Stones; Loading Stones Into The Heater - Sawotec TH2-30NB Bedienungsanleitung

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. The required amount of stones is also listed in the manual
provided. See page 12 (Technical Diagram).
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. Load the stones to the heater so
that the heating elements are not visible from any angle. First place stones to
the lower part of the heater by rotating the rings to make space for loading the
stones. Put the rings back properly and load the rest of the stones from the
top. Make sure that the elements don't get bended or touch each other as a
result of the loading. 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.
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.
