What are the clearances required by code from my Kitchen Exhaust Hood and ductwork to combustible, limited combustible, and noncombustible materials?

Why does my Kitchen Exhaust Hood need to be welded?

NFPA-96 Section 5.1.2 requires that all seams, joints and penetrations of the hood enclosure that direct and capture grease-laden vapors and exhaust gases shall have a liquidtight continuous external weld to the hood’s lower outermost perimeter. This helps to contain a fire within the hood where it can be extinguished by the exhaust hood’s fire suppression system.
