Stop if

Hold point on grease duct cleanout location and spacing: I have the location, photo, drawing/detail, and what was checked. Who should verify before this gets cut, covered, lifted, sealed, energized, or signed off?

Watch out

Don't install without verifying cleanout locations. Don't place above unremovable ceilings. Don't assume hood manufacturer handles cleanouts.
