9.3. Chimney sweeping
The opening in the stone compartment is a soot hatch (covered with a cap).
The inner parts of the heater are cleaned through the soot hatch 2 to 6 times a year according to use.
Empty and clean the stone compartment and check the condition of the stones at the same time. Soot hatches open when
they are lifted upward parallel to the surface.
If the cap has stuck because of temperature fluctuation, use a bending iron or a hammer.
9.4. Cleaning the fire chamber glass
Handle the glass door carefully. Do not bang the door shut or use it for pushing wood into the furnace. Clean the glass with
Noki Pois or similar soot cleaning agent.
10. Troubleshooting
If the heater or the sauna doesn't perform as you think it should, check it following the below list. Make sure you have
selected the correct heater to match the sauna room's volume.
The heater is too hot (red-hot)
The draft exceeds -12Pa
- lower the draft with the damper
The stones are laid too tightly or they are too small.
- place the stones more loosely and use stones that are min. 10 cm in diameter.
There's too much wood, or the pieces are too small.
- Table 2 has the maximum amounts of wood for the heater, do not use more.
- Do not burn large amounts of small pieces of wood, because their temporary heating effect is high.
- let the previous batch of wood become embers before adding the next batch
There's smoke in the sauna room, the draft is bad.
Turn off all equipment that may cause low pressure.
Is the damper open?
Is the connection pipe sealed against the heater and the flue?
Is the alternative flue opening sealed with the included cover?
Are the heater's soot hatches securely shut?
Is there ash in the heater channels?
Is the interconnecting pipe from the heater to the flue free from ash?
Is the flue completely open? Is it unswept, filled with snow, covered with winter cover etc.
Is the chimney in good condition? Cracks, weathering.
Is the draft height (chimney height) sufficient for the surrounding environment?
- If there are trees close by, a steep hill etc., the chimney needs to be over 3.5 m measured from the floor.
Is the flue size correct?
- the minimum diameter is half a brick for brick flues or 115 mm for round flues
The stones do not become hot enough.
Have you burned enough wood in the furnace?
Burn enough wood in the heater, refer to the amounts of wood in Table 2.
Is the draft too weak?
Is the amount of stones correct?
- At the sides, there should be stones to the level of the sides, and in the middle, only half a stone can raise above the side
level.
Are the stones too tightly packed?
- Place the stones loosely, so there will be enough space between the stones.
Are the stones of good quality and the right size?
-use peridotite or olivine stones with a minimum diameter of 10 cm. Place flat stones vertically.
The sauna room won't become warm enough.
Are the doors, windows and air conditioning closed, and the combustion air opening open?
Is the sauna new, are the wooden structures damp for some other reason?
Is the heater used correctly?

- Burn according to instructions.
Is the draft too strong?
- Use the damper to adjust the draft.
Is the draft too weak?
