Which term represents guidelines provided by the manufacturer for installation?

• A. Gauge Pressure
• B. ASME B16.4
• C. Nonmetallic Pipe
• D. Manufacturer's Instructions

Answer: (D)

Guidelines provided by the manufacturer for installation are called the manufacturer's instructions. These are the product‑specific rules that tell you exactly how the item must be installed to function correctly and stay within its listed limits. In NFPA 13R work, following these instructions is essential because they often add or clarify requirements beyond the general standard, such as how to mount, clearances, materials, or temperature and pressure limits. The other terms don’t address installation guidance: gauge pressure is simply a pressure measurement, ASME B16.4 is a standard for fittings, and nonmetallic pipe is a type of material. So the manufacturer’s instructions are the clear term for installation guidelines.
