Customer Fuel Line Cut Off Valve
Beginning May 2015, Nicor Gas will install a second valve downstream of the meter bar outlet on all new and replacement natural gas service installations. This second valve, known as the Customer Fuel Line Cut Off Valve, will be located at the outlet of the meter bar and will help prevent misuse of the service inlet valve.
The first valve (Nicor Gas’ normal inlet valve) is owned by Nicor Gas. This valve falls under the jurisdiction of 49CFR Part 192.The Nicor Gas Service Valve is to be operated and maintained by Nicor Gas personnel only.
As Nicor Gas’ responsibility for meter sets ends at the outlet of the meter bar; and it is possible that others may have a need to control the flow of natural gas to the customer; the second valve (Customer Fuel Line Cut Off Valve), serves as a non-jurisdictional component of the meter set. Having this component available for operation will allow a qualified HVAC professional to control the flow of natural gas and relight appliances.
Nicor Gas will place tags on all new and replacement natural gas services receiving a Customer Fuel Line Cut Off Valve alerting you that this second valve has been installed and cautioning that only qualified HVAC and plumbing professionals are to operate the Customer Fuel Line Cut Off Valve.
