We are going to install a stove in our house that we are renovating. In the picture below, you can see how we plan to position it. The chimney is behind on the right side. On the left side, we plan to extend part of the wall, where the white board is, so we don't run into it.
Our problem is that the left wall is made of wood. What heat-resistant material should we use? Minerit board, siporex block?
The instructions state that the stove should be 600 mm from combustible materials and 300 mm from rugs and similar items in front of the stove. If we were to place a minerit board or something similar on the left wall, could we then reduce the distance between the wall and the stove, and if so, by how much?
We had hoped to have about 15-20 cm from the wall, is that possible?
Isn't there a top view sketch showing the distance to non-combustible & combustible walls? In Contura's brochures, they have sketches of it so you can plan before purchasing a stove, also available in the installation instructions that come with the stove.
Here is an example, the measurements are different between models.
Hello..
use the minerit board, it's easier to fix the finishing work on it..
but also place a board behind the stove, so the corner has a complete look with the fireplace..
and also place drywall behind the minerit for extra good...and safe...
a distance of 15 - 20 cm feels good, so go with that.
I would do it like this...frame as usual, then put up the drywall, then I would cut 5 cm strips of the minerit and distribute three on each board lengthwise from floor to ceiling as spacers between the drywall and the minerit..
this way the heat stays in the minerit and doesn't reach the drywall. A very safe construction...
And remember to pre-drill the minerit so it doesn’t break when you screw it up..
Under the stove, what will you have there..????
Eti..
That should be in the installation instructions for the stove. At least when it comes to sauna stoves, a minerit board halves the distance to combustible materials, but the board must be installed with an air gap behind it. I don't remember the measurement for the air gap but at least 30 mm, so it won't look very nice in a living room.
Does the stove have glass both at the front and back? Compared to something like the contura stoves, this model doesn't seem particularly suitable for corner or wall installation.
It is always best to have "stone walls" near stoves, but get in touch with the chimney sweep, that's where you'll get the correct answer.
It's also him who will inspect the installation.
Yes, now I see that I'm being fooled by the shadow behind the stove. But still. 60cm to combustible material. What were they thinking when they designed that stove...?
According to my chimney technician (those who perform fire protection inspections and approve new installations), no boards or wooden walls are approved to reduce the distance from the stove to combustible parts. Only stone 10 cm (brick, aerated concrete or lightweight clinker) is acceptable. I asked when I was considering replacing my wood stove with a pellet stove.
I recently read on the Sotarbolaget website that if you install an 8 mm fibercement board (minerit) on a wooden wall and have a distance (air gap) of 25 mm, you can reduce the distance tothe stove by25 cm, otherwise it is 50 cm that applies...to combustible... There are alternatives ..... Eti..
There might be alternatives, yes. "My" chimney sweep technician is known to be "strict." Otherwise, one would think these regulations should reasonably be the same across the country, but as usual, there's a sense that there's room for interpretation.
Since it's ultimately the chimney master or chimney sweep technician who needs to approve your fireplace & chimney, the obvious tip is to check with them first. It's always unfortunate to have to redo something if the authorities are being difficult.
It is also possible to make a wall of minerit on a metal stud filled with rock wool according to the instructions I linked to. I built one that the chimney sweep approved. Chimney sweeps seem to be a strange breed. Or at least they do not follow national regulations. What works one time does not work another time.
According to my chimney technician (those who conduct fire safety inspections and approve new installations), no boards or wooden walls are approved to reduce the distance from the stove to combustible parts. Only 10 cm stone (brick, lightweight concrete, or lightweight clinker) is okay. I asked when I was considering replacing my wood stove with a pellet stove.
So Tylö, Harvia, and others are out there lying in their installation instructions? No, your technician is sailing off course!
50 cm without boards, 25 cm with a board with an air gap, 12.5 cm with two boards and double air gaps is what applies.
Thank you for all the answers. We visited a stove shop today and they had a thick sheet of fireproof material that you could buy. They said it didn't matter how hot the stove was, you could place it 5cm from that material anyway.
