If you’re working on a plumbing project and considering tapping into an existing copper gas line to run CSST (Corrugated Stainless Steel Tubing) to your stove, you may have some concerns. Here’s what you need to know about the process and whether it’s a good idea.
Question: Can I tap into the 3/8″ copper line to run CSST to my stove?
Answer: No, the 3/8″ copper line is likely too small to support both the gas fireplace and stove. Gas lines need to be sized correctly to supply enough gas to each appliance, and 3/8″ copper may not provide adequate flow for both. It’s best to run CSST back to where the black iron line enters and tee off there. This will ensure sufficient gas pressure and flow for your stove.
Question: Do I need to run CSST inside the conduit when it’s installed in a garage?
Answer: Yes, CSST should be run inside a conduit when installed in an exposed area like a garage. This helps protect the flexible tubing from physical damage and meets building code requirements for gas line installations in exposed locations.
Additional Considerations:
-
Gas Line Sizing: Ensure that your gas line is properly sized to meet the needs of all appliances. For multiple appliances, your system must be designed to handle the required load without reducing pressure.
-
Professional Testing: Once the CSST is installed, always have a licensed plumber or gas technician test the system before using it. This is to confirm that everything is connected correctly and safely.
