4.10 Electrical Bonding of FlashShield™ CSST
a) ere are no additional bonding requirements for FlashShield™ imposed by the manufacturer’s installation instructions.
FlashShield™ is to be bonded in accordance with the National Electrical Code NFPA 70 Article 250.104 in the same manner
as the minimum requirements for rigid metal piping. However, installers must always adhere to any local requirements
that may conflict with these instructions.
b) If the authority having jurisdiction requires that all CSST systems shall be bonded, the gas piping system shall be considered
to be direct and bonded when installed in accordance with the following:
• A single bond clamp attachment to rigid pipe or rigid component at any point within the gas piping system
- Bond clamp attachment downstream of individual gas meter or 2nd stage regulator for propane systems, and in
accessible location
- Metallic contact is required (remove paint or plating on steel pipe)
- Bonding clamp listed to UL 467
• Bonding conductor is #6 AWG copper (minimum) or equivalent, and not exceeding 75 feet in length
- e shortest practical bond wire length will improve the effectiveness of the direct bond
• e bonding conductor is permanently and directly connected to the electrical service grounding electrode system of the
premises. is connection can be made at either:
- Bonding buss
- Grounding electrode conductor
- Grounding electrode
• Any additional grounding electrodes used shall be bonded to the electrical service grounding electrode system
• Direct bonding to be performed by a person qualified to do so per local ordinances
• e bonding conductor shall be installed and protected in accordance with:
- National Electrical Code, NFPA 70, (NEC)
- Canadian Electrical Code, CSA-C22.1, (CEC)
