Additional Information

M3 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 a 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 variations 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 infrequent 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:

1. Close the ash box, stove door, and damper plate (if installed).
2. Contact local fire authority.
3. Do not try to extinguish the fire using water.
4. After a soot fire, a chimney sweeper must check the stove and the flue before use.

• Inspect and Replace Stones: Check sauna stones for cracks or damage and replace them as needed for consistent heat distribution.

• Check Ventilation: Ensure that air vents are clear and unobstructed to maintain proper combustion and airflow.
• Inspect the Door Seals: Check the door seals for wear and replace them if they no longer create a tight seal, preventing heat loss.
• Store Wood Properly: Use dry wood and store it in a dry area to ensure efficient burning and prevent excessive smoke.
