The <br /> requirement providcs un cffective electrically oontinuvus path in an eflort to conduct stray voltage%urrent <br /> safely to ground. Thc NEC also states that it is gooci practicc to bond all mctallic systems and ohjects. In <br /> accordance�vith thesc requirements,WARDFLEX�requires the gas-piping system to be bonded to the <br /> elech-ical earth gmunding systcm of the swcture thmu�h the usc of a bondin�clamp and�vire. <br /> • The bonding point must be in as close pro�imity to thc clectrical panel as practical;close proYimity of <br /> the bonding point to the gas meter is al�desirahle. <br /> • The wire gauge for this bond must bc sizcd,nt a minimum,for the full amper�ge available through the <br /> clectric scrvicc. <br /> • Further minimizing impodance ovcr the bonding assembly is desirnble. The NEC should be referred to <br /> for additional requirements and�ccific techniques for bonding und grounding. <br /> For attachment to thc WARDFLEX°D gas <br /> piping sysiem,bonding clamps must bc eONDING WIR � <br /> attached to the WARDFI,EX°D brass fittins,to <br /> a steel manifold,or to a rigi'd pipe component � <br /> c:onn�tcxl to a WARDI�I,EX'�'fitting.

NFPA 54 specifically requues: <br /> "...each above ground ponion oja gas prping system whicli is li�fcly to become energized shnl!be <br /> electrically continuous and bonded to a designed,permcrnent,low impedance e,(fective ground <br /> jault current palh." <br /> Proper grounding and bonding may reduce tl�e risk of dauna�Ge and fire from a lightning strike. Lightning is <br /> a highly dcstrvctive force. Even a neerby lightning strike that docs not stril:e a structure directly can caus� <br /> systems in ihe s�ucture to become energized. If the systems ure not properly bondcd,the diffe�nce in <br /> potential betwcen the systems may cause the charge to arc to another system. Arcing can cauce d�age to <br /> i <br /> CSS"I'. 13onding and gmunding as set forth ahove should reciuce the ri�k of arcing and related damage. <br /> Depending upon conditions specific to the location of the structure in which ihe WARDFLEX��y,stem is <br /> being installed,including but not limited to whether or not the area is prone to lightning,the owne�of thc <br /> structure shouid considet whether or not u lightning protection system is necessary or appropriate. <br /> Lightning protection systems are beyond the scope of this bulletin,but are cavered by NFpp 7gp�yhich is <br /> the Standard for the Installation of Lightning Protection Systems,and other standards. <br /> Released On: l 1/1/06 <br /> Scanned by CamScanner <br /> �� <br />
