David, I wouldn't think that a dipole of any kind would put too much of a strain on your chimney. Even with the balun, that one only weighs 1.2lb (per DX Engineering - https://www.dxengineering.com/parts/mfj-2010).
Since whatever you use as a mount will weigh more than the antenna, just be sure to use a lightweight mount. Disclaimer - this only my opinion. I've never mounted an antenna on a chimney before.
