Grease Duct, Kitchen Exhaust & Industrial ExhaustSTOP / VERIFYField judgment

Core Answer

Verify the required clearance, listed wrap or shaft system, access, support, and penetration details before closing the route around grease duct.

This grease duct uses [wrap/shaft system]. Can we verify clearance, wrap details, supports, and access treatment before this area is closed?

Do not compress listed wrap, mix systems, bury access, or assume wrap automatically eliminates every clearance requirement.

The protection works only as a complete listed assembly installed and inspected as specified.

Verify against: approved listing and manufacturer instructions, project drawings/specs, AHJ and foreman direction.
