Installation of cassette in existing fireplace

[GusMohra]

I am in the process of renovating my fireplace to install a cassette and I wonder if I really need Silca fireproof board since the fireplace is already fireproof and made entirely of brick? I have no combustible materials there, so to speak.

I would appreciate any advice I can get.

No, you probably don't need to...

Have you checked if your chimney can handle a modern insert?

In order for you to start using the stove (final approval), an inspection certificate from a chimney sweep must be submitted to the municipality, so I recommend that you contact one now and consult on how to proceed. It would be unfortunate if you put effort into something that doesn't get approved. You should also notify the municipality of the "installation of a fireplace."

I found this article on the forum, it might be helpful.

I recommend having the chimney inspected before buying and installing the insert. It's unfortunate if the chimney sweep rejects it during the inspection when everything is finished.

I will not install it myself; a company will do it, but I am preparing by rebuilding the fireplace so that the cassette fits. The chimney has been inspected and approved, and according to the company that will install the cassette, the chimney should handle it.

Pressure testing by the chimney sweep was ordered before I contacted the stove company. I eventually decided to install a small stove in the fireplace.

Thanks! I will do that since it will not be me installing the cassette itself, but will be done by the company I ordered the cassette from (eldabutiken).

Thanks! I've already done that and it's approved.

I ordered a pressure test from a chimney sweep before I contacted the stove company. Finally decided to install a small stove in the open fireplace.

thanks! I did the same, had a chimney sweep on site before the summer who swept and did a pressure test, and everything was approved.

But does what TS wants to do really count as such a major alteration to the existing fireplace that it indeed requires a building notification? According to Boverket, renovating a fireplace or replacing an existing stove with a similar one does not require a building notification. Can't an insert be considered a renovation of the existing fireplace?

The municipality I live in requires a building notification when installing or replacing a fireplace and the municipality also wants a control plan for the building notification, which is then filled in during the course of the work.

All municipalities have their regulations regarding such changes/installations of fireplaces.

I needed to file a building notification to install a fireplace in the open hearth. I had considered a cassette, but the hearth is very large and didn't think it was worth the extra work to brick it down.

Hmm, it's possible that these changes might be seen as more significant than renovation, or alternatively as a replacement with an equivalent fireplace, but I'm starting to wonder if municipalities are coming up with their own rules.

I need to check with the municipality I work in myself.

The guidance from the National Board of Housing, Building and Planning is, for me, very clear.

I have actually checked this and it is quite well explained on the National Board of Housing, Building and Planning's website about what applies, etc.

To answer my own question. An insert in an open fireplace is specified as a significant alteration of the hearth. BFS 2017:4 VÄS 3.

Then I assume it is because an insert in an open fireplace changes the effectiveness? That is, it could affect the chimney or the construction of the chimney?
