ᐅ Fireproof partition wall behind the fireplace?!

Hello everyone,

I have a question regarding our planned fireplace and the related regulations. Unfortunately, reading through the various requirements has not made things any clearer. We purchased a fireplace from Hark, model "mamorkamin 1/222.0," about six months ago (before construction started), based on our floor plan designs. We were only told that our electrician needs to install a cable to the range hood. The installation would be handled by the seller. They also said that, with our floor plan, the location of the fireplace would not be a problem.

Now that the shell of the building is complete, and we are about to begin electrical, plumbing, and underfloor heating work, the fireplace supplier is talking about a partition wall behind the fireplace. They want to know who will build it. Nothing about this was mentioned in the past six months. Of course, we received this email just before the end of their working day, so we couldn’t ask for clarification today about what exactly is meant.

Our fireplace is planned in the center of a room, near the corner of a wall. So it is hardly touching any wall. Behind the fireplace is an air supply duct for the fireplace, and behind that is the chimney. Side clearances for tiles have been planned. I will try to upload a photo excerpt of the ground floor plan. Can someone explain if, in this situation, an additional fireproof partition wall is really necessary or what we should consider?

Thanks in advance for any help.

Best regards,
Paule

I understand the plan and the fireplace as follows: according to your layout, there is no rear wall. Is it meant to remain uncovered at the back?
The model you chose should have its back against a wall...

Am I missing something here?
Masonry walls are fire-resistant. Plaster is fire-resistant in this sense. Tiles are as well. What is not acceptable would be wallpaper or wooden walls, such as paneling and similar materials.
And if it is supposed to stand free, fire resistance of a non-existent wall becomes irrelevant.
At least that is my understanding.

Good question. Until an hour ago, we assumed the back panel would be covered by the seller just like the side panels since they knew it wouldn’t be placed against a wall. We intended to install only a small drywall element between the fireplace and the chimney to cover the fresh air intake pipe.

We thought so too. Meanwhile, we found a fire protection note which unfortunately doesn’t provide any relaxation.

We thought so too. Meanwhile, we found a fire protection notice that at least doesn’t provide any relief.

For me, and possibly for others here, it’s unreadable? It’s blurry...

Invite the chimney sweep. They will tell you how it needs to be done for them to approve it.
