CSST appliance connectors should not pass through walls. CSST distribution piping can. That is an appliance connector. ---

> [@bking](#): > > CSST appliance connectors should not pass through walls. CSST distribution piping can. > That is an appliance connector. Depends on your AHJ. Here, the wall must have a **sleeve** for (CSST dist. pipe) to pass through. Agree, no on the CSST appliance connector. ---

CSST is not allowed to be used directly to an appliance around here either. Check local code but this is what I have… CSST is not designed to be used as a flexible gas appliance connector and shall not be used as a substitute. The use of CSST as a final connection for permanently installed appliances, such as water heaters, furnaces, and boilers is allowed. CSST shall terminate outside of the appliance jacket where the excessive heat may ignite or damage the protective coating. The use of CSST as a final connection of movable gas appliances, such as ranges and clothes dryers, is not allowed. CSST shall not be installed outdoors and shall not be run underground unless installed in a sleeve or conduit. ---
