Quick Answer
CSST systems do not all carry the same supplemental bonding instructions. Identify the manufacturer and exact product line, then follow the current installation manual, adopted electrical and fuel-gas codes, and local amendments.
Product identity changes the question
Traditional yellow-jacket CSST, arc-resistant systems, and shielded products are not interchangeable compliance categories. The manufacturer’s listed installation instructions can impose requirements that a broad ‘bond the gas piping’ statement does not answer.
Do not decide a final installation from jacket color alone. Confirm the manufacturer, product line, listing, fitting system, and current manual.
Bonding is not a separate-ground-rod shortcut
Where bonding is required, the goal is to integrate the metallic system with the building grounding and bonding system as required by the applicable instructions and code. A separate grounding electrode is not a substitute for the prescribed connection.
Clamp location, conductor size, accessibility, listed hardware, and routing are all product-specific details that should be checked against the actual manual.
Use a repeatable field check
Identify the installed system. Obtain the current manual. Verify whether supplemental bonding is required and where the connection is permitted. Then verify the adopted code and local amendment path.
Always verify the code edition adopted by the local jurisdiction, applicable state and local amendments, equipment listing, and manufacturer installation instructions.
Common Mistakes
- Assuming every CSST product has a #6 bonding rule.
- Identifying a product only by jacket color.
- Using an unapproved clamp location.
- Skipping the manufacturer manual.
- Treating a separate ground rod as the solution.
Bottom Line
Ask what exact CSST system is installed and what its current instructions require. That is more precise—and safer—than relying on a generic answer.
