Service questions
Details worth understanding.
Final specifications depend on the inspected conditions, appliance listing, selected manufacturer and applicable local requirements.

No. The crack location, depth, movement and surrounding material determine whether monitoring, joint repair, brick replacement or rebuilding is appropriate.
