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. See section 3.2. on adjusting the draft and heating efficiency.
Has the heater been sized according to the instructions?
There are black flakes under the heater.
The stones may be weathered.
The flakes can be metallic anvil cinder, fallen off the heater. The heater has been heated too much red-hot; the metal will
flake and the heater will break prematurely.
There's a smell of sulphur in the sauna.
The stones have sulphur residues from blasting, or the stone includes sulphur naturally.
