CSST and Lightning

lightning strike
Lightning is a highly destructive force. Even a nearby lightning strike that does not strike a structure directly can cause all electrically conductive systems in the structure to become energized. Nearby lightning strikes can result in a power surge that can damage certain gas tubing systems and ultimately cause a fire. Properly bonding and grounding the Corrugated Stainless Steel Tubing (CSST) significantly reduces the risk of damage and fire from a lightning strike.

Care should be taken when installing CSST to maintain as much separation as reasonably possible from other electrically conductive systems in the home. Electricians and other trained professionals should consult local building codes as to required separations for CSST from conductive systems including metallic chimney liners, metallic appliance vents, metallic ducting and piping, and electrical cables.

Areas with high lightning risk include but are not limited to: Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Michigan, Mississippi, Missouri, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Tennessee, Texas, Virginia and West Virginia.
