Steps
Verify size, fitting type, and airflow/branch direction.
Check the connection method: coupling, collar, flange, gasket, screws, or sealant.
Support the duct so weight is not deforming the joint.
Focus on the actual issue: not checking pitch/slope on special exhaust round duct.
Photograph or mark the condition if someone else needs to approve it.
Say this to your foreman
In Spiral, Round & Oval Duct Install, I'm looking at: Pitch/slope on special exhaust round duct not checked. What should I verify before I cut, drill, seal, cover, move, or install?
