Raise the floor under tiles by the fireplace

[Mortsken]

Dug out the floor according to this: https://www.byggahus.se/forum/threads/ta-bort-asfalt-pa-kaellarvaegg.484561/

Now I want the stove back, I thought.
I have tiles that I will use. But the floor is now about 2cm lower.
So I need to raise it by 2cm.
One option is to just tile directly on the self-leveled floor and put something under the feet.
This is the one that should go there: https://www.byggahus.se/forum/threads/aer-trollapeisen-gjutjaernskamin-godkaend-att-anvaenda.503224/

Since there's going to be a rug on the rest of the floor, I think it's better to raise it these 2cm.
How do I do this?
Just put in a form and self-level?
Maybe drill down some rebar so that it is anchored with the floor?

The best approach is to level up to the required height and lay the tiles directly, just ensure that the tiles extend at least 0.5 meters in front, otherwise there will be a metal sheet there and about 20 cm outside the sides and behind. Using cut wooden strips to seal off works well, just lubricate the edges with regular cooking oil so they don't stick to the flow.

0.5 meters in front and 20 cm outside the stove, you mean? Is it a rule that it has to be at least this? What do you think about the need to anchor the leveling in the floor somehow?

Primer on existing surface if it's concrete is sufficient, you can, if you're a bit worried, lay down a piece of plaster mesh as reinforcement. According to the regulations for stoves, it should be non-combustible in front of and around a stove. Think about when you're poking in the stove, embers spill out, and if there is anything combustible too close, you'll get scorch marks on the floor. So there's probably no shortcut for you to take there.

Yes, I'll have both in front and on the sides.
But if it's not a strict rule that it has to be 0.5 and 0.2 and it happens to be 0.45, I'm okay with that. But not according to the rules
So, if it is a rule I clearly have to make sure to follow it exactly.

5 cm here or there doesn't matter, as long as there is room for any embers to land on. It depends a bit on the size of the plates and what there is room for in the hole/notch.

Call your chimney sweep and check the regulations. I believe it is 10 cm on the sides and 30 in front of the door, but I'm not sure.

The rules for spark protection on a stove (closed fireplace) state 30 cm in front and 10 cm on each side. The rules that jonaserik writes are for an open fireplace. Additionally, if you have an elevated open fireplace (over 40 cm), you should add half of the excess measurement. For example, if you have an open fireplace where the opening is 50 cm above the ground, you add 50-40=10, 10/2=5 cm
