In our house, part of the kitchen has been mounted against a chimney breast on the opposite side of which there is a stove insert. If I understand correctly, a pipe has been installed in the flue to lead the smoke up and out.
On the chimney breast, OSB and gypsum have been mounted with nail plugs (or equivalent) and then the kitchen cabinets have been hung on the OSB/gypsum.
After reading on Byggahus, I've realized that this might not be correct from a fire safety perspective.
My question is HOW dangerous is this? Is there a risk that the OSB boards might catch fire when the stove is used?
When the chimney sweeper comes next time, can he/she remark that there is a new kitchen on the other side of the wall from the stove and condemn the stove and the flue?
Do I have to/should I tear down and attach the OSB boards in another way? Like with glue? Or not have OSB boards at all?
Grateful for any input!

The chimney sweep at my place during the inspection said I couldn't put OSB directly on the wall, I had to use a metal stud.
End grain was fine against it but not standing wood.
But as mentioned above, ask the chimney sweep, they're the ones who inspect and not us at byggahus.
Don’t think they'll remark on or think about it.
Then it's up to one's own conscience if you want it fireproof or not.

One reason I'm asking here and not the chimney sweep is because I don't want a burning ban if the risk is near zero that something will happen (the stove is only used for "cozy fires"). There are many wise people here on the forumViktor.J said:

Is it that it's an old chimney with several different masonry channels in it? In the past, they made the chimneys larger and had one channel for stove/boiler and then some for ventilation. Do you know if there was wallpaper on the chimney before they put OSB/drywall on it?N Nils Karlsson1 said:One reason I'm asking here and not the chimney sweep is that I don't want a burning ban if the risk is close to zero that anything will happen (the stove is only used for "cozy fires").

It's an older one from the '60s with two channels, one for the kitchen ventilation to which the kitchen fan is connected and next to it a flue for the former open fireplace, now the stove/insert.M Myrkebab said:
There was an original kitchen in the same place before, but not attached/screwed to the chimney, and perhaps they thought differently in the '60s when the house was built...
I thought if there had been multiple channels, you might have gotten a bit more distance between the smoke channel and the kitchen side. And if the chimney had been wallpapered before OSB/drywall, it would have given an indication of how hot it can get. If it had gotten really hot, the wallpaper shouldn't have survived. Otherwise, as previously mentioned, it's the chimney sweep who decides. Feels like it's unwise to take a chance.

if you have a liner inside the chimney flue, you have both belt and suspenders, as you would need to burn HARD for several days before the radiant heat first warms up the gap to the inside of the chimney and then the chimney itself to 100 degrees to ignite the OSB-n.-.
(as a comparison, I have tried burning HARD for a couple of hours (about 8h) to test my installation and I didn't reach too high a temperature on the outside of my masonry chimney (half brick)., maybe 60-70 degrees) and it was only the spot where the flue gases hit the masonry wall that got that hot...

But the chimney sweep should still inspect at regular intervals, right?N Nils Karlsson1 said:One reason I'm asking here and not the chimney sweep is because I don't want a burning ban if the risk is close to zero that something will happen (the stove is only used for "cozy fires").
