3.5. Sauna Water
The water to be thrown on the heated stones should meet the requirements of clean household water. Only special
aromas designed for sauna water may be used. Follow the instructions given on the package. Throw sauna water on
the stones only. If you throw water on the hot steel surfaces, they may blister due to the large temperature
variation!

3.6. Maintenance
Stove
• The ash box should always be emptied before heating the stove so that the combustion air that is lead through
the box would cool off the fire grate and lengthen its life span. Get a metal container, preferably standing model,
to put the ash in. As the removed ash may include hot embers, do not keep the ash container close to combustible
material.
• Soot and ashes gathered in the smoke canals of the stove should be removed occasionally through the soot
openings
.
• Due to large variation in temperature, the sauna stones disintegrate in use. Therefore, they should be rearranged
at least once a year or even more often if the sauna is in frequent use. At the same time, any pieces of stones
should be removed from the stone space, and disintegrated stones should be replaced with new ones.
• Wipe dust and dirt from the stove with a damp cloth.
Chimney
• The chimney and connection pipes should be swept at regular intervals and especially if the stove has not been
used in a long time.
• Due to incomplete burning of fuel and failure of sweeping the chimney, the soot build-up in the flue may ignite.
Actions to be taken in case of a chimney fire:
• Close the ash box, stove door and damper plate (if installed).
• Contact local fire authority.
• Do not try to extinguish fire using water.
• After a sootfire, a chimney sweeper must check the stove and the flue before use.
3.7. Troubleshooting
There is no draught in the flue. Smoke comes into the sauna.
• There are leaks in the flue connection. Seal the connection (› Connecting the Stove to a Masonry Flue).
• The brick flue is cold.
• There is low pressure caused by an extractor fan or another device in the room. Make sure there is enough air to
compensate.
• Several fireplaces are used at the same time. Make sure there is enough air to compensate.
• The ash box is full.
• The smoke canals of the stove are blocked ( › Maintenance).
• The flue connection pipe is too deep in the chimney ( › Connecting the Stove to a Masonry Flue).
