Ensuring a Successful Gas Meter Set Gas Meter Header has been kept plumb and square Final grade has a minimum clearance of 6” to the bottom of the meter Gas regulator vent maintains 18” minimum height from grade Gas regulator vent meets 18” clearance requirements from windows, doors, otheropenings into the building Gas regulator vent maintains a minimum of 10’ from any mechanical air intakes Gas regulator vent terminus maintains 3’ from any source of ignition Gas regulator vent and meter header maintains a minimum of 12” horizontally from anyelectric meter pans or electric meters Electric meters meet clearance requirements and are not installed directly above thegas regulator or meter header Electric meter has been installed and the dwelling is powered up Customer owned piping has been sleeved or properly cold wrapped for protection ifgoing through a masonry wall Multiple meter header has been properly secured to the wall Multiple meter headers have had ID tags installed identifying the units locations Protection posts shall be installed to code if required to prevent vehicular damage Make up air requirements meet combustion needs City, State, Town, or Village pressure test certificate has been left on site for NationalGrid if required by the authority having jurisdiction before meter can be set All customer owned piping is installed to National Grids Blue Book requirements, andmeets City, State, Local, IFGC code. All CSST products must meet manufacturer’sbonding requirements.Check with the authority having jurisdiction to verify the code they are following National Grid has access to the dwelling to install meter and fire one piece of equipmentto obtain Lock Up and Running PressuresGAS METER SET APPOINTMENT CONTACT NUMBERNew York/Long Island 1-877- MyN-Grid
IMPORTANT NOTICEREGARDINGNATIONAL GRID SPECIFICATIONS AND REQUIREMENTSFOR GAS INSTALLATIONSThese Specifications and Requirements have been designed with great careso that, when followed consistently, they will ensure that a new installationwill comply with New York State law, various codes and other safetyrequirements. Failure to comply may result in a code or safety violationand/or a job not being approved. Therefore, delays could result while thecontractor corrects the changes at his/her expense.The specifications, construction standards and other requirements containedin this book represent National Grid commitment to the contractingcommunity for quality and consistency of service. Any variation from thetype of hardware used, connection point of service, service entrance orother details on a construction standard must be approved in advance byNational Grid in writing.We at National Grid are always available to discuss your design concernsand to provide assistance to you. We encourage any questions regardingyour problems on specific projects, please be sure to contact us for our inputduring the planning stages to avoid possible additional costs later in the job.Paul Gugliotta – Materials & Standards/Gas EngineeringPaul Cama - Customer FulfillmentPeter Polumbo – Policy & ProceduresClem Sebastopoli – Meter OperationsRichard Stark – Gas Growth Support - Long IslandTim Restivo – Gas Growth SupportRobert Zabielski - Gas Customer Meter ServicePaul Smith – Gas Growth Support – NY CityChris Marconi – Gas Customer Meter Services
