9 December 2020 Page 1 of 58 33 1 INTRODUCTION PURPOSE This book presents specifications and requirements relating to the connection and use of natural gas supplied from the National grid Gas System. It contains the minimum acceptable standards for gas piping and gas appliance installation necessary to ensure the safe and satisfactory utilization of natural gas by our customers. The information contained herein is intended primarily to assist the installer in the new gas installation process, but it is also intended for use by our customers, by architects and engineers, and finally, by people in various departments at National grid . It shall be used when a customer's gas installation is new, when a customer is increasing gas usage from a smaller capacity, or when any changes are made from the original installation . It represents a collection of information which will provide for a safe, properly conceived, accurately sized and cost effective installation that will give long lasting, satisfactory service to our customers.

10 The operation of the head of service valve or meter valve is restricted to National grid s Operator Qualified personnel. National grid s jurisdictional ends at the outlet of the National grid meter. SCOPE/REFERENCES The contents of this book apply to installations connecting gas supply system to a customer's premises. We have made it as comprehensive as is practical, within the limits of the intended overview of the subject matter it addresses. The intent of the book is to provide a framework for the subject, not a collection of specific information from various sources. Generally, it refers to several primary documents which form its basis: a. The National Fuel Gas Code (NFPA 54/ANSI ), latest revision, referred to in the book as NFPA 54. (COVERS CUSTOMER OWNED PIPING AFTER THE GAS METER) b. The New York State Codes, Rules and Regulations Title 19 (16 NYCRR 255 and 261), latest revision, referred to in the book as NYCRR.
