Fireproof partition wall behind the fireplace?!

Hello everyone,

I have a question about our planned fireplace and the associated regulations. Unfortunately, we are no wiser after reading the various requirements. We already bought a fireplace from Hark "mamorkamin 1/222.0" six months ago (before construction started) with our floor plan designs. We were only told that our electrician has to lay a cable for the extractor hood. The seller takes care of the installation. Furthermore, it was said that with our floor plan the location wouldn't be a problem. Now that the shell of the building is standing and soon the electrical/plumbing and underfloor heating work will begin, the fireplace seller is talking about a partition wall behind the fireplace. He wants to know who will build this. Nothing was said about this in the last six months. Of course, we received the email shortly before their closing time and were no longer able to ask today what exactly is meant by that. Our fireplace is planned in the middle of the room at a corner wall. It is therefore hardly against any wall. Behind the fireplace is an air supply pipe for the fireplace and behind that the chimney. Lateral clearances for tiles are planned. I will try to attach a photo excerpt of the ground floor plan. Can someone explain to me whether in this situation an extra fireproof partition wall is even necessary or what we need to consider?

Thanks in advance for any help.

Regards

Paule

I am trying to upload a photo snippet of the ground floor plan. Can someone explain to me whether in this situation an extra fireproof partition wall is necessary at all or what we need to consider?

I understand the plan and the fireplace now in such a way that in your floor plan there is no back wall. Should it stand uncovered at the back? The model you have chosen must have its back against a wall...

Am I missing something now? Brick walls are fireproof. Plaster is fireproof in this sense. Tiles too. What doesn't work would be wallpaper or wooden walls, meaning paneling and similar. And if it should stand freely, the fire resistance of a non-existent wall is unnecessary. At least that is my understanding.

Good question. Until an hour ago, we assumed that the back wall, like the side parts, would be covered by the seller since they knew it would not stand against a wall. Only a small drywall element was supposed to be installed between the fireplace and the chimney to cover the supply air duct.

Masonry walls are fireproof. Plaster is fireproof in this sense. Tiles as well. What is not allowed would be wallpaper or wooden walls, such as paneling and the like.
And if it is supposed to stand freely, fire resistance of a non-existent wall is irrelevant.
At least, that is my understanding.

We thought so too. Meanwhile, we found a fire protection notice that at least brings no relief.

Not readable for me and possibly for others here?
It is blurry...

Invite the chimney sweep. He will tell you how it has to look so that he approves it.
