Ceiling radiation dampers and diffusers that are tested and listed as an assembly must be installed according to what?

• A. Local Building Codes
• B. Architect's Guidelines
• C. Manufacturer's Installation Instructions
• D. Industry Standards

Answer: (C)

The requirement for ceiling radiation dampers and diffusers to be installed according to the manufacturer's installation instructions is critical for ensuring their proper function and effectiveness. These installation instructions include specific guidelines on how to properly integrate these components into an HVAC system, taking into account aspects such as orientation, sealing, and clearance requirements. Following the manufacturer’s directions is essential because these products are tested as specific assemblies, and any deviation from the recommended installation practices may compromise their performance, potentially leading to failures in preventing the spread of fire and smoke. Adhering strictly to the installation instructions guarantees that the products will operate as intended during a fire, thereby maintaining the safety of the building and its occupants. It also helps in ensuring compliance with relevant fire safety regulations and standards, which are often aligned with manufacturers’ specifications.
