How to Bond a CSST Gas Line: A Comprehensive Guide with Diagrams

Connecting and bonding a Corrugated Stainless Steel Tubing (CSST) gas line is crucial for safety and compliance. Improper bonding can lead to dangerous electrical hazards. This guide provides a step-by-step explanation, including diagrams, to ensure you complete this task correctly and safely. Always consult local codes and regulations before starting any gas line work. Improper installation can lead to serious injury or death. If you are unsure about any part of this process, contact a qualified gas fitter or plumber.

Understanding CSST and Bonding

CSST, due to its metallic nature, can become a pathway for stray electrical currents. Bonding creates a low-resistance path to ground, diverting these currents and preventing sparks or fires. This is a critical safety feature, especially during lightning strikes. The bonding wire needs to be properly sized and connected according to the manufacturer’s instructions and local codes.

Key Components for CSST Bonding:

• CSST Gas Line: The flexible, corrugated stainless steel tubing carrying natural gas.
• Bonding Wire: Usually copper, sized according to the gas line's diameter and local codes. Never use aluminum wire for bonding.
• Bonding Clamps: Securely attach the bonding wire to the CSST and the grounding electrode. These clamps must be properly sized and corrosion-resistant.
• Grounding Electrode: This is typically a ground rod driven into the earth, providing a path to ground. It could also be connected to the electrical service's ground rod. Check local codes for requirements.
• Approved Connectors: Use only connectors specifically designed for CSST gas lines. These will be clearly marked as approved.

Step-by-Step Guide to Bonding a CSST Gas Line

This process involves connecting the CSST line to the grounding electrode system. Multiple bonding points might be required depending on the length and configuration of the gas line.

Step 1: Gather Materials and Tools

• CSST Gas Line
• Bonding Wire (Copper)
• Bonding Clamps (Corrosion-resistant)
• Grounding Electrode (if needed)
• Grounding Rod Clamp
• Wire Strippers/Cutters
• Screwdriver (appropriate size for clamps)
• Level
• Measuring Tape
• Wrench (if needed for connectors)
• Safety Glasses and Gloves

Step 2: Locate the Grounding Electrode

Identify your existing grounding electrode. This is often a ground rod driven into the earth near the gas meter or electrical panel. If one doesn’t exist, you may need to install one. Consult with your local authorities on requirements.

Step 3: Attach the Bonding Wire to the CSST Line

Using a bonding clamp, securely attach the bonding wire to the CSST gas line. Ensure the clamp makes firm contact with the tubing. This is typically done near the gas meter. Multiple bonding points may be necessary depending on the length of your CSST line. Local codes will dictate the specifics.

Step 4: Connect the Bonding Wire to the Grounding Electrode

Attach the other end of the bonding wire to the grounding electrode using an appropriate clamp. Ensure a tight and secure connection. If using a ground rod, ensure it's driven deep enough into the earth.

Step 5: Inspect Connections

Carefully inspect all connections to ensure they are secure and that there are no loose wires. Any loose connections could compromise the bonding and create a safety hazard.

Step 6: Testing (Optional but Recommended)

A qualified technician can test the bonding system to ensure it provides a low-resistance path to ground. This is not always required by code, but it's a prudent step to confirm the safety of your installation.
