CHAPTER 12
FUEL GAS PIPING
1203.0 Inspection.1203.1 Inspection Notification. Upon completion of the¶
installation, alteration, or repair of gas piping, and prior to the use thereof, the Authority Having Jurisdiction shall be notified that such gas piping is ready for inspection.
1204.0 Certificate of Inspection.1204.1 Issuance. Whereupon final piping inspection, the¶
installation is found to be in accordance with the provisions of this code, a certificate of inspection shall be permitted to be issued by the Authority Having Jurisdiction.
1205.0 Authority to Render Gas Service.1205.1 Authorized Personnel.¶
It shall be unlawful for a person, firm, or corporation, excepting an authorized agent or employee of a person, firm, or corporation engaged in the business of furnishing or supplying gas and whose service pipes supply or connect with the particular premises, to turn on or reconnect gas service in or on a premises where and when gas service is, at the time, not being rendered.
1206.0 Authority to Disconnect.1206.1 Disconnection. The Authority Having Jurisdiction¶
or the serving gas supplier is hereby authorized to disconnect gas piping or appliance or both that shall be found not to be in accordance with the requirements of this code or that are found defective and in such condition as to endanger life or property.
1207.0 Temporary Use of Gas.1207.1 General. Where temporary use of gas is desired, and¶
the Authority Having Jurisdiction deems the use necessary, a permit shall be permitted to be issued for such use for a period not to exceed that designated by the Authority Having Jurisdiction, provided that such gas piping system otherwise is in accordance with the requirements of this code regarding material, sizing, and safety.
1209.0 Excess Flow Valve.1209.1 General. Where automatic excess flow valves are¶
installed, they shall be listed to CSA Z21.93 and shall be sized and installed in accordance with the manufacturer’s instructions. [NFPA 54:5.13]
1211.0 Electrical Bonding and Grounding.1211.1 Pipe and Tubing other than CSST.¶
Each aboveground portion of a gas piping system other than CSST that is likely to become energized shall be electrically continuous and bonded to an effective ground-fault current path. Gas piping, other than CSST, shall be considered to be bonded where it is connected to appliances that are connected to the appliance grounding conductor of the circuit supplying that appliance. [NFPA 54:7.13.1]
1212.0 Appliance and Equipment Connections to¶
Building Piping.
1214.0 Required Gas Supply.1214.1 General. The following regulations shall comply¶
with this section and Section 1215.0, shall be the standard for the installation of gas piping. Natural gas regulations and tables are based on the use of a gas having a specific gravity of 0.60 and for undiluted liquefied petroleum gas, having a specific gravity of 1.50. Where gas of a different specific gravity is to be delivered, the specific gravity conversion factors provided by the serving gas supplier shall be used in sizing piping systems from the pipe sizing tables in this chapter.
