4.3. Sweeping
The hatches in the stone compartment are for sweeping (covered with lids).
The stove’s internals are cleaned through these hatches 2–6 times a year, depending on use.
If the stove is connected to the chimney from the top, soot will drop into it, which needs to be
removed.
4.4. Removal and cleaning of the stove's glass
The glass door must be treated with care. Do not slam it shut or uses it to push logs into the
stove. The glass doors are cleaned with Kastor’s Noki Pois cleaning fluid.

5. Troubleshooting
If the stove or the sauna fails to work as you think they should, go through the following check
list.
First, to make sure you have chosen the correct stove for your sauna’s requirements, look
through the stove choosing instructions on our internet pages at www.kastor.fi -> “wood burning”
-> “select your stove”.
Smoke leaks into the sauna, bad draft.
Is the chimney valve open?
Is the connecting pipe attached tightly both to the stove and the chimney?
There mustn't be any air leaks.
Is the stove’s other flue opening closed tightly with the cap that came with the stove?
Is the flame plate in the upper part of the stove clean of ash?
Is the connecting pipe between stove and chimney clear of ash?
Is the chimney fully open?
In need of sweeping, stuffed with snow, winter cap on etc.
Is the chimney intact?
Cracks, weathered
Is the draft height (chimney height) sufficient with regard to the environment?
Nearby trees, a steep hill etc. requires more than 3.5 metres (11.5’) as measured from the
chimney floor.
Is the chimney’s size correct?
At least a half brick wide or, depending on stove model, a round chimney of 100 or 120 mm
(4 - 4 13/16”).
The stove stones do not heat up sufficiently.
Has the stove been fired sufficiently?
You should burn at least one compartment full of split, dry logs according to instructions.
Is there too much draft?
The flames reach into the connecting pipe, which is red hot, although the lower end of the
stove within the mantle is not red. See chapter 3.3. about draft adjustment and heat output.
Is the draft too weak?
See chapter 3.3. about draft adjustment.
Correct amount of stones?
