Installation instructions for one manufacturer's firestopping products ___.

• A. Are specific to that product made by that manufacturer
• B. Are generic and can be followed for other manufacturer's products
• C. Are optional and can be adapted
• D. Are not to be used outside the manufacturer’s guidance

Answer: (A)

Installation instructions for a firestop product are tied to the exact product from that manufacturer because firestop systems are tested and listed as specific assemblies. The tested performance depends on the exact materials, joint sizes, substrates, curing times, and installation steps defined for that product. Following the precise instructions ensures the assembly achieves the rated fire resistance and maintains the listing. Using generic steps, or applying another manufacturer’s methods, can violate the listing and compromise the firestop’s effectiveness. So the installation instructions are specific to that product made by that manufacturer.
