proper gas tight bonding procedure??????????

[plott hound]

last year we did 3 blocks of 8 plex units,complete HVAC installations.we ran gas tight from each gas meter to each furnace in every block.at the furnace we tied into our black pipe "sets" with the gas tight and the electricians bonded on the black pipe.my question is although its not our responsibilty how is the gas tight supposed to be bonded?

                                                cheers.

In your example the electricians should have installed additional upstream bonding.

Read the CSST Bonding thread here,

http://www.hvactechgroup.com/hvacforum/index.php?topic=997.0

It may not be in your scope of work to supply and install the bonding but the gas code, Clauses 4.7.1 & 4.7.3 require you to.

4.7 Electrical connections and components

4.7.1
Electrical connections between an appliance and building wiring shall comply with the local electrical code or, in the absence of such, with the Canadian Electrical Code, Part I.

4.7.3
All interior metal gas piping that may become energized shall be made electrically continuous and shall be bonded in accordance with the requirements mandated by the Electrical Safety Authority.
Note: Refer to ESA Bulletin 10-14-2 and subsequent amendments.

Even though the gas company may have turned on the gas meter and activated the appliance and the electricians were paid to install the bonding I could see the TSSA coming after the company and person listed on the pressure test tag if there was an incident.

Please note ESA Bulletin 10-14-2 has been replaced with ESA Bulletin 10-14-6.

We started using Flashshield to avoid having to install additional bonding.
