Hole through the corner in the chimney

[hesalex95]

I am considering installing a stove. Due to room limitations, it would be easiest to make a hole in the chimney diagonally, i.e., from the corner straight towards the center/flue.

Geometrically, it should work, and there are corner flue connectors with the right dimensions that would fit once the hole is there, but what would be the easiest way to make the hole and do it well? Drill many holes in a circle around the hole's circumference just like on a flat wall, even though you have to drill at an angle, or should you try to remove whole bricks and then build around the flue connector again with shaped bricks?

Most laborious but perhaps neatest would be to rebuild the corner to 45 degrees (like an octagonal chimney) and then be able to drill perpendicular to the surface.

Any tips?

Go around the corner with sheet metal pipe and into the chimney if possible, then you have additional heat to get,
the pipe gets nice and hot, why burn for the crows

Go around the corner with a metal pipe and into the chimney if possible, then you have additional heat to extract, the pipe gets very hot, why waste heat?

You mean going sideways and drilling the hole on the flat side of the chimney breast? Sure, that's an option if space is available, but here the challenge is that it would be much more practical to go in through the corner, i.e., at a 45-degree angle. To the extent that if a corner entry is too complicated to achieve well, it's better to place the stove elsewhere. The chimney breast is positioned here so that one side is close to a wall, and on the adjacent side, there's room traffic, making it feel cramped and risky to have a flue there, unfortunately.

Have not installed a chimney pipe in a corner, but it probably requires a special sheet metal for the connection, I don't think it's available as standard and a sheet metal worker needs to make one. Corners are certainly more difficult to make a hole in because it is a joint in the masonry, but it might be possible.

Haven't cut in any smoke pipe in a corner, but it probably requires a special sheet metal as a connection, I don't think it exists as standard; instead, a sheet metal worker has to make one. The corners are probably more difficult to get a hole in because it's a bond in the masonry, but it might work.

Hm, yes, we'll see. Not sure yet how the pipes in the chimney stack go, so just at the planning stage.
