  • It is not possible to combine multiple flue extensions to accommodate a ceiling taller than 10'.
  • If the ceiling is higher than 10', the customer will have to make a custom flue extension.
  • Wolf does not have, nor recommend, specifications on custom flue extensions.
  • If a custom extension is used, it is easiest to slide the custom piece into the lower flue that comes with the hood since the attachment points to the hood are already made into the lower piece.
  • For installation of CT Hood without upper flue, see Cooktop Low Profile Wall Hood without Flue.
  • Refer to the product Installation Guide or the Wolf Design Guide.
