Is the connection pipe sealed against the heater and the flue?
Is the connecting pipe installed so that the shorter end is connected to the heater? (Check this through the soot hatch in the
stone compartment.)
Is the alternative flue opening sealed with the included cover?
Is the heater's soot hatch 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 peridolite or dunite stones, min. 10 cm in diameter. Flat stones are placed in an upright position.
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?

The sauna heats up quickly, but the stones are not hot.
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.
Is the heater too big?
- keep the ventilation valve open to keep extra heat out. This way the stones will have time to heat up as well.
It will take a bit longer to heat the sauna this way.
The water doesn't heat up properly in a heater model with a water tank.
Is the draft too strong?
- There's a flame in the interconnecting pipe, which is red hot, even though the lower part of the heater, inside the cover,
does not burn red.
Has the heater been sized according to the instructions?
Check if the side of the water tank facing the heater frame is painted black.
There are black flakes under the heater.
The flakes can be metallic anvil cinder, fallen off the heater. This indicates that the heater has been used too aggressively,
causing the metal to flake and the heater to break prematurely.
Do not heat the sauna heater so that the cover is constantly red-hot.
There's a smell of sulphur in the sauna.
The stones have sulphur residues from blasting, or the stone includes sulphur naturally.
