How to put up an inner wall bordering a masonry chimney?

[GrodanMaja]

We are going to build an interior wall, with one side adjacent to an old brick chimney. The chimney is currently not used other than as a ventilation duct, but we obviously want to do it correctly in case we want to use it later. There was an old wall in the same place where we are building our new one, and it was constructed with wooden studs, one of which was nailed to the chimney. We've been told that wooden elements should not be closer than 10 cm to the chimney, so we have purchased a metal stud that we plan to place against the chimney and leave the floor and ceiling studs (wood) 10 cm from the chimney (according to the recommendations we got at the hardware store). But now we're starting to get a bit unsure if we can/should just screw a metal stud into the chimney. Does anyone know what I'm talking about and how we can do it in the best way?

Place the sheet metal 100mm from the chimney and fill in with stone wool in between. Then you're safe. Are you planning to put plaster on it afterwards?

How much brick is there to the channel inside the chimney? It is described in some building code how much is required to be able to mount wooden studs against the chimney. And if there is no flue channel, the chimney does not get hot.

Wooden carpenter: You mean that we don't attach a beam directly to the chimney but instead build the "frame" so it's 10 cm away? That's what we initially thought but then decided to place a metal beam so that we still have a beam at the outermost part on each side. And yes, we will use plasterboard.

imported_Benno: No idea how far it is to the flue. There's no burning flue in the chimney right now, but we want to treat the chimney as if there was one so that we have the option to use the chimney for burning later if we want/can/may.

The reason I'm asking if we can screw a beam directly to the chimney and what we might need to consider when doing so is because we just have a bad feeling about screwing into a chimney, but we actually don't know if it's a problem at all and what, if anything, could be problematic.

If there is only half a brick between the flue and the outside, there is a risk that the temperature will become high enough for combustible material to ignite.
