ᐅ Retrofitting a chimney and connecting a stove pipe on the first floor

Hello,

We are planning to retrofit a tunnel fireplace stove in our house. In addition, a lightweight chimney system needs to be installed. However, the lightweight chimney is not going to be built from the foundation but from the first floor (1st floor / first storey) next to a gallery. The fireplace stove will be installed on the ground floor, and the stove pipe will be connected to the lightweight chimney on the first floor. According to regulations, the stove pipe is generally not allowed to span more than one floor. In this case, however, there is the special circumstance that the stove is to be built within a gallery.

We would like to install the chimney on the first floor, as this would allow us to avoid making a wall opening and also enable the chimney to be positioned relatively close to the ridge, which was introduced as a new legal requirement this year.

We have already had a friend who is a stove fitter and chimney sweep visit the site. However, he works as a chimney sweep in a different area. He said that connecting the stove pipe on the first floor to the chimney through a gallery is a gray area and that approval would depend on how lenient the local chimney sweep is.

What is your opinion on this? Please also see the following concept images:

Sorry, your "our" opinion should actually be completely irrelevant to you. It’s unlikely that the chimney sweep from your district is reading this forum and will share their view here.

That’s the person you should ask. Involving the relevant experts early on has never harmed me in life. On the contrary. If you later tell them (because they will come anyway!): The forum said "this should basically be approvable," they will probably turn around on the spot! And rightly so 😳. But all of that is just my humble opinion 😉

Close the thread and ask the chimney sweep responsible for your area. There is nothing more to add, as they have the final say and are basically the ultimate authority on chimneys.

It is indeed the case that in Germany, stove pipes are generally not allowed to pass through building components. For example, you are not permitted to run a stove pipe through a floor. However, if there is enough air space around the stove pipe—around 30 to 50 cm (12 to 20 inches)—then it is possible to span multiple floors.

However, I am no longer certain if it is still permitted to operate two stoves using a single chimney.

If that is the case…

… then I clearly see a flue pipe that runs from the ground floor through the upper floor, thus passing through more than one level.

In Germany, it is generally true that stovepipe ducts are not allowed to pass through structural elements.

If a wall is also considered a structural element, then that is not entirely correct.
Our stovepipe goes from the living room through the hallway wall and continues in the hallway to the chimney. The chimney inspector approved it like that last year.

Regarding the original question, I can only advise: call the chimney inspector and have it decided on site.
