CSST Grounding Question

Hello Everyone,
I am from Toronto, getting TracPipe CounterStrike CSST installed in my home. I have asked the person installing the product to ground the TracPipe CSST system however he said that my main gas line is already grounded and since he’s attaching the csst sytem to that , he does not need to ground it. I am not an expert and i want to understand if what he is saying is correct or in correct. Can anyone give me some insight to this?


To a degree, he is correct. However, CSST requires additional bonding in certain areas where lightning strikes are more common.

Manufacturers of CSST have published lightning density zone (LDZ) maps that are used to determine if additional bonding is necessary.

Gas pipe, including rigid, cannot be used for grounding. The pipe is bonded, not grounded. Two entirely different purposes.


Can you post this link

I thought that we answered that pretty well in your thread on the Mike Holt Code Forum. :smiley:


Yep, and I know better :mrgreen: It was early… On a Monday morning…

I will look for it this evening…

Here is an example of what I am referring to…


TracPipe® CounterStrike® Advantages

csst lightningThere are no additional bonding requirements for TracPipe® CounterStrike® imposed by the manufacturer’s installation instructions. With TracPipe® CounterStrike®’s improved properties, TracPipe® CounterStrike® is to be bonded in accordance with current requirements of the National Electrical Code (NFPA 70), and the National Fuel Gas Code (NFPA 54), and with any local requirements that may be in excess of the national codes. This may result in the avoidance of additional bonding costs which are required for conventional CSST.
