Do not force larger stones in place if they do not fit in between the heating elements.
They should be removed.
Small pieces of stone (35mm in diameter) must not be put inside the heater as they can block the
air circulation, which can cause overheating resulting to damage of the heating elements.
NOTE: A damaged heating element due to overheating caused by using the wrong kind of stones
or incorrect loading of stones will not be covered by the factory warranty.
Before turning on the Combi Heater, make sure that nothing else but stones are placed inside or
near the unit. For more safety instructions, please refer to Part 4 – Precautions section of this
manual. Bad odor may be detected when using the Combi Heater for the first time. To remove the
smell, just ventilate the Sauna Room.
It is important that you choose the correct power rating of the Combi Heater that will correspond
to your Sauna Room size. Part 6 (Technical Data) of this manual will help you to make the right
choice. A properly selected Combi Heater allows to reach the bathing temperature within an hour.
If the heater power is too big for the Sauna Room, the room will heat up faster than the stones and
will cause the water thrown on the stones to go through the stone compartment too quickly. On
the other hand, if the heater power is too little for the Sauna Room, the water thrown on the
stones will not increase the temperature; instead, it will only cool the stones thus decreasing the
temperature inside the Sauna Room.
Your Sauna Room must have suitable insulation and wall materials. Refer to Part 8 (The Sauna
Room) of this manual for guidance. The bathing temperature should preferably be within the
range of 65 to 80 degrees Celsius, while the Steamer is switched off.
Throwing water on the stones increases the moisture level inside the Sauna Room and the heater
increases the temperature.
The amount of water thrown on the stones determines the moisture content of the air.
Three ladles of water at a time are enough to enjoy the Sauna. Throwing too much water on the
stones may cause scalding water to splash on the bathers, as the water may not evaporate
immediately.
Make sure there is no one sitting near or next to the heater before throwing water on the stones.
3.3.
3.2.
Use only clean household tap water to throw on the stones.
Do not use hard, ferrous or chlorinated water.
Hard water causes white deposits on the stones and on the heater surface, and it also decreases
the heat accumulating property of the stones.
On the other hand, if the water you are using is ferrous, a rusty layer will cover the heating
elements and other parts of the heater and will lead to corrosion.
The use of seawater, chlorinated water and humus water can damage your Combi Heater and its
parts as well.
The Savonia Combi Heater has a 5-liter Water Tank. When filled with 5-liter water, steam can be
produced for approximately 2 hours if set to max.
Super Savonia Combi Heater has two tanks that are linked by a connecting hose at the bottom,
with 5-liters and 3.5-liters water capacity respectively. When filled with water at maximum level,
steam can be produced for approximately 2 hours.
To ensure ideal humidity, the Sauna temperature should be between 40 and 50 degrees Celsius,
and the Steamer should be left on for 30 minutes to pre-heat the Sauna room and produce
sufficient amount of steam before bathing.
