Answer to Question 1

A visual inspection is necessary to determine the need for cleaning.

Answer to Question 2

One end of the duct is crimped, making it's outside diameter slightly smaller than the regular duct diameter. A bead behind the crimp serves as a stop when inserting one duct into another. All joints should be fastened with sheet metal screws or rivets. The joint should be sealed with UL 723 duct tape and or mastic.
