When installing CSST _____

When installing CSST _____

• A. Keep the protective plastic jacketing in place to protect the tubing from corrosion
• B. Remove the protective jacketing after installation
• C. Paint the CSST after installation
• D. Bury CSST directly in soil

Answer: (A)

Keeping the protective plastic jacketing in place is essential because that jacket serves as a moisture barrier and physical shield for the CSST. Leaving it intact helps prevent corrosion and damage to the tubing, which keeps the system safer and in line with the manufacturer’s installation instructions. Removing the jacket can expose the metal to moisture and environmental factors, potentially voiding warranties and compromising the gas line. Painting isn’t appropriate because coatings can trap moisture and interfere with the jacket’s protective function. Burying CSST directly in soil isn’t allowed as-installed without following specific protective measures per code and manufacturer guidelines.
