The main purpose of the sauna stones in the heater is to store enough energy to efficiently vaporize the water thrown on top of the stones to create temperature increase in the sauna. The stones must be removed at least once a year or every 500 hours which ever occurs first. All crumbles must be removed from the heater and replaced with new ones as described in the heater manual.

Never use the heater without stones as it may cause fire. 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!

桑拿石在加热器中的主要目的是储存足够的能量，以有效地蒸发扔在石头顶部的水，从而使桑拿房的温度升高。这些结石必须每年至少清除一次，或每500小时清除一次。所有碎屑必须从加热器上清除，并按照加热器使用手册中的说明更换新的碎屑。

不要使用没有石头的加热器，因为它可能引起火灾。使用不合适的石材可能导致加热元件损坏，并将使保修无效。千万不要使用陶瓷石或其他任何类型的人造石！
