Installation Instructions

Proper bonding and grounding may reduce the risk of damage and fire from lightning strikes. Lightning is

a highly destructive force. Even a nearby lightning strike that does not strike a structure directly can

cause metallic systems (such as wiring, piping and ductwork) in the structure to become energized. If

these systems are not properly bonded, the difference in potential between the systems may cause the

charge to arc from one system to another and cause damage to the CSST. Bonding instructions set forth

above should reduce the risk of arcing and its related damages.

Depending upon conditions specific to the location of the structure in which the Pro-Flex® system is

being installed, including but not limited to whether the area is prone to lightning activity, the owner of

the structure should consider whether a lightning protection system is necessary or appropriate. Lightning

protection systems are beyond the scope of this manual, but are covered by NFPA

780, the Standard for

the Installation of Lightning Protection Systems, and other standards.

As with all Pro-Flex® guidelines, the techniques outlined within this manual/bulletin are subject to all

local fuel gas and building codes.
