This code shall apply to the installation of fuel-gas piping systems, fuel-gas appliances and related accessories in accordance with Sections 101.2.2 through 101.2.5.

Piping systems.

These regulations cover piping systems for natural gas. High pressure natural gas installations at pressures of 15 psig (103.4 kPa gauge) or above shall also comply with the requirements of Appendix G of this code. Coverage shall extend to the outlet of the appliance shutoff valves. Piping system requirements shall include design, materials, components, fabrication, assembly, installation, testing, inspection, operation and maintenance.

Gas utilization appliances.

Requirements for gas appliances and related accessories shall include installation, combustion and ventilation air and venting and connections to piping systems.

Systems and equipment outside the scope.

This code shall not apply to the following:

1. Portable LP-gas appliances and equipment of all types that are not connected to a fixed fuel piping system.

2. Oxygen-fuel gas cutting and welding systems.

3. Industrial gas applications using gases such as acetylene and acetylenic compounds, hydrogen, ammonia, carbon monoxide, oxygen and nitrogen.

4. Petroleum refineries, pipeline compressor or pumping stations, loading terminals, compounding plants, refinery tank farms and natural gas processing plants.

5. Integrated chemical plants or portions of such plants where flammable or combustible liquids or gases are produced by, or used in, chemical reactions.

6. LP-gas installations at utility gas plants.

7. Liquefied natural gas (LNG) installations.

8. Fuel gas piping in public utility power plants and atomic energy plants.

9. Components within proprietary items of equipment, apparatus or instruments such as gas-generating sets, compressors and calorimeters.

10. LP-gas equipment for vaporization, gas mixing and gas manufacturing.

11. Temporary LP-gas piping for buildings under construction or renovation that is not to become part of the permanent piping system.

12. Installation of LP-gas systems for railroad switch heating.

13. Installation of hydrogen gas, LP-gas and compressed natural gas (CNG) systems on vehicles.

14. Except as provided in Section 401.1.1 and Appendices E and G, gas piping, meters, gas pressure regulators and other appurtenances used by the serving gas supplier in the distribution of gas, other than undiluted LP-gas.

15. Building design and construction, except as specified herein.

16. Piping systems for mixtures of gas and air within the flammable range with an operating pressure greater than 10 psig (68.9 kPa gauge).

17. Portable fuel cell appliances that are neither connected to a fixed piping system nor interconnected to a power grid.

Other fuels.

The requirements for the design, installation, maintenance, alteration and inspection of mechanical systems operating with fuels other than fuel gas shall be regulated by the New York City Mechanical Code.
