CSST piping systems should be installed according to what?

CSST (Corrugated Stainless Steel Tubing) piping systems must be installed according to both NFPA 54 guidelines and the manufacturer's instructions to ensure safe and effective operation. NFPA 54, also known as the National Fuel Gas Code, provides comprehensive standards for the design and installation of gas piping systems. This code covers safety requirements, installation practices, and performance criteria that help prevent hazards associated with gas leaks and ensure that the system operates effectively.

Additionally, following the manufacturer's instructions is critical because these specifications are tailored to the particular product being used. They provide specific guidelines on installation practices, recommended materials, and safety measures that are crucial for optimal performance and compliance with safety standards.

By requiring adherence to both NFPA 54 and the manufacturer's instructions, installers ensure that the piping system is not only compliant with relevant codes but also aligns with the specific requirements of the products being used. This dual compliance optimizes safety and performance, protecting both the property and its occupants.
