GrodanMaja and the Carpenter's Shed:
If you follow the Carpenter's Shed's recommendations, you'll be on the safe side in ensuring that the chimney's flue channels will function properly. If you start building around the chimney now and then install the stove, regardless of the distance of adjoining walls to it, etc., you might have to tear it all down so that the chimney sweep can check if there's any leakage.
Therefore, let the chimney sweep come now to do a pressure test on the flue channel you plan to use. This way, you can also get exact advice on how to connect walls, etc. In other words, the chimney sweep takes over as your 'consultant' and is responsible for ensuring that you build correctly, and should problems arise later, you're protected. Make sure to have this recorded or get it in writing.
The chimney sweep may indeed criticize older solutions, but should refrain from doing so, as these may have been carried out according to older regulations and were therefore perfectly acceptable when the house was built. New standards do not automatically have retroactive effect on older standards, except in certain specific cases, such as the installation of a new wood stove. That is, influences that didn't exist then may mean the new installation increases, for example, the fire load and therefore requires a different solution than before.

I can agree that it is smart to pressure test beforehand, but we are not going to encase the chimney. The new wall will only touch it with a surface of 70mm times the height, so it will still be accessible later. And the thing with the fireplace and reusing the chimney is far in the future if we even decide to do it at all...
Maja>The chimney benefits from being used now and then. It may also be the case that parts of the house, like attic spaces, benefit from the chimney being used as it was used before. A stove can, so to speak, provide more effects than just the supply of energy and coziness.

imported_byggaren: I have tried to get answers from Boverket today, but the only thing I got was that there's a difference between if it's a requirement or advice/recommendations.
Do you know if the rules about 5 cm between the chimney and wooden beam are a requirement or just a recommendation?
We were thinking of placing horizontal wooden beams, but they will not be attached to the chimney; instead, they will run above the wall that already exists on each side of the chimney. We plan to attach gypsum panels to these.
The chimney is already built in on two sides. What material, I do not know.
Does anyone know what applies if it was built against these rules before they were in effect? You can't tear up the old stuff, right?

A small update if anyone is interested; The requirement is related to how many degrees the chimney wall can reach. If it's not more than 75/85 degrees, you can build with wood against it. The recommendations are stricter...
Checked with the insurance company as well and they are satisfied as long as the requirement is met.
