Before the dryout procedure is submitted for approval, what must be finalized?

The correct choice emphasizes the importance of reviewing provisions with the manufacturer before submitting the dryout procedure for approval. This step is critical because it ensures that all specific requirements, recommendations, and guidelines provided by the manufacturer are understood and incorporated into the dryout process. This collaboration can help prevent issues that might arise during the dryout phase, as the manufacturer's insights are vital in aligning the procedure with the material specifications and capabilities.

Having a comprehensive understanding and agreement with the manufacturer can also facilitate a smoother approval process, as it demonstrates to the approving authorities that all necessary precautions are taken into account. Additionally, this step helps ensure that the dryout process will be effective and safe, following best practices that have been established by the manufacturer, thus reducing the risk of failures in the refractory lining.

The other choices, while important in their own contexts, do not capture the essential requirement of finalizing details that directly involve the manufacturer's input into the dryout process.
