Where can support spacing information for CSST be found?

Manufacturer's installation and operation manual
Local plumbing code
Online resources
Engineering textbooks

The correct answer is: Manufacturer's installation and operation manual

Support spacing information for CSST (Corrugated Stainless Steel Tubing) is typically provided in the manufacturer's installation and operation manual. This manual is specifically designed to give detailed guidelines on the installation process, including the necessary support spacing for the tubing to ensure safety and compliance with relevant standards. Manufacturers conduct testing and research to determine the optimal spacing needed to support the CSST, taking into account factors such as the tubing's diameter, intended application, and environmental conditions. Therefore, referring to the manufacturer's manual is the most reliable approach for obtaining accurate and specific support spacing information tailored to that particular product. While local plumbing codes, online resources, and engineering textbooks may contain useful general information, they may not reflect the unique specifications provided by the manufacturer. Each CSST product can vary, and adherence to the manufacturer's guidelines is essential for proper installation and to ensure the system operates safely and effectively.
