Appendix G High Pressure Natural Gas Installations

This code shall be known and may be cited as the "New York City Fuel Gas Code," "NYCFGC" or "FGC." All section numbers in this code shall be deemed to be preceded by the designation "FGC."
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.
These regulations cover piping systems for natural gas. High pressure natural gas installations at pressures of 15 psig (103 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.
Requirements for gas appliances and related accessories shall include installation, combustion and ventilation air and venting and connections to piping systems.
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.

16. Piping systems for mixtures of gas and air within the flammable range with an operating pressure greater than 10 psig (69 kPa gauge).

17. Portable fuel cell appliances that are neither connected to a fixed piping system nor interconnected to a power grid.
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.
The purpose of this code is to provide minimum standards to safeguard life or limb, health, property, public welfare and the environment by regulating and controlling the design, construction, installation, quality of materials, location, operation and maintenance or use of fuel gas systems.
If a section, subsection, sentence, clause or phrase of this code is, for any reason, held to be unconstitutional, such decision shall not affect the validity of the remaining portions of this code.
Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall govern. Where, in a specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern.
Except as otherwise provided for in this chapter or elsewhere in this code, a provision in this code shall not require the removal, alteration or abandonment of, nor prevent the continued utilization and maintenance of, existing installations lawfully in existence on the effective date of this code.
Additions, alterations, renovations or repairs related to building or structural issues shall be governed by Chapter 1 of Title 28 of the Administrative Code, the New York City Building Code and the 1968 Building Code, as applicable.
Installations, both existing and new, and parts thereof shall be maintained in proper operating condition in accordance with the original design and in a safe condition. Devices or safeguards that are required by this code shall be maintained in compliance with the applicable provisions under which they were installed.
The owner or the owner's designated agent shall be responsible for maintenance of installations. To determine compliance with this provision, the commissioner shall have the authority to require an existing installation to be inspected.
Additions, alterations, renovations or repairs to installations shall conform to that required for new installations without requiring the existing installation to comply with all of the requirements of this code. Additions, alterations or repairs shall not cause an existing installation to become unsafe, hazardous or overloaded.
Minor additions, alterations, renovations and repairs to existing installations shall meet the provisions for new construction, unless such work is done in the same manner and arrangement as was in the existing system, is not hazardous and is approved.
In addition to the requirements of Sections 102.4 and 102.4.1, the provisions of Sections through shall apply to prior code buildings.
For prior code buildings, the replacement of existing fuel gas piping in the same locations shall not be subject to Section 404.1, Item 5, when approved by the commissioner.
