Listed exhaust hoods with or without exhaust dampers shall be permitted to be assembled in accordance with the ______.

• A. Listing
• B. UL Standards
• C. Code
• D. Listing Requirements

Answer: (D)

Listing requirements are the established conditions that a listed exhaust hood assembly, with or without dampers, must meet to be considered approved. When a product is listed, the listing package specifies exactly which configurations are evaluated and permitted, including how the hood is assembled, what components are allowed, and any limitations. Installing the hood strictly according to those listing requirements ensures the assembly has been tested and evaluated for the intended fire-protection performance, and it gives the authority having jurisdiction a clear basis to approve the installation. Using the general code or a broad UL standard without aligning to the specific listing can lead to configurations that haven’t been evaluated, compromising both safety and compliance.
