PREFACE

This Book is dedicated to the memory of Paul Bernauer. Louisville Gas and Electric Company (LG&E) provides retail gas and electric service in a defined service territory in and around the Metro Louisville, Kentucky area. The Commercial & Industrial Customer Gas Piping Handbook is intended to address natural gas service issues for Commercial and Industrial customers within the prescribed service territory. This Document is intended to supplement the Customer Gas Piping Handbook. A separate document, “Electric Service Handbook”, details the requirements for electric service.

Customer Gas Piping Handbooks
The Customer Gas Piping Handbooks (both Commercial and Residential) prescribe LG&E’s standards with respect to gas service and meter installations pursuant to the rules and regulations of the Kentucky Public Service Commission (KPSC). All piping used for gas service lines and meter installations must be installed in accordance with the specifications provided by LG&E and will be subject to inspection and testing by LG&E. In the event that special circumstances prevent compliance with the service line specifications prescribed within this handbook, LG&E will give proper consideration to alternative methods, provided that applicable regulations are not violated and that safety and reliability are not jeopardized. The Customer has the responsibility of notifying LG&E of any changes to the piping, appliances, or building structure that may affect safety or gas system performance. This Commercial and Industrial Customer Gas Piping Handbook includes standards pertaining to the Commercial and Industrial Customers’ service, meter loop and house line piping, in the interest of uniform and safe operations. The standards for piping are generally applicable for replacement or relocation of existing facilities. The Commercial and Industrial Customer Gas Piping Handbook is applicable to customers with a total connected natural gas load of 500,000 BTUH or greater. LG&E reserves the right to modify the requirements found in this handbook or any of its service policies, procedures and/or standards at any time. It is the responsibility of the Customer to ensure that any reference document is the version currently approved for use by LG&E. It is also the responsibility of the Customer to notify LG&E of any changes to natural gas facilities that may affect safety or natural gas system performance. By publishing this handbook, LG&E does not assume liability or responsibility for house piping, appliance installation, or appliance operation. LG&E maintains the right to refuse to supply gas to piping or appliances that are installed or operated in a potentially unsafe manner. In addition, LG&E is not responsible for continuing inspection or surveillance of Customers’ house piping, appliances, or appliance operation.

EXCAVATION SAFETY
Call before you dig – It is the Law
The Underground Facility Damage Prevention Act (KRS 367.901-367.917) was enacted by the Kentucky legislature in 1994. This law requires all persons excavating in the state of Kentucky to have underground facilities located prior to starting excavations. Violators of this law may be subject to fines and/or criminal prosecution. Kentucky 811 is the answer to the continuing problem of damage to underground facilities. Kentucky 811 provides a communication link between excavators and operators of underground utilities. Kentucky 811 is a nonprofit organization made up of owners and operators of underground facilities in the Commonwealth of Kentucky.

Please call Kentucky 811 at least two business days and not more than ten business days prior to your planned excavation with the information listed below. There is no cost to the caller! • • Identity of contractor or excavator: name, address, etc. Dig site location: County, nearest city, inside/outside city limits, street name or highway name, address number, the nearest cross street intersection or other description if address is not available. Digging information: Type of work, depth of dig, location within property or right-of-way, method of excavation. Estimated date and time of excavation.

IN KENTUCKY CALL BEFORE YOU DIG…. KNOW WHAT’S BELOW…. IT’S THE LAW Dial: 811 Or www.kentucky811.com





In turn, Kentucky 811 will contact its member companies for you to have the underground facilities located in the vicinity of your planned excavation. In addition, they will advise you as to what utilities will be notified, and will provide you with a request number for your reference and documentation.

NATURAL GAS SAFETY
Safety First – Providing Safe Natural Gas Service
The health and safety of LG&E’s customers and employees and the general public are our highest priorities. LG&E believes strongly in the concept that safety is everyone’s responsibility. LG&E’s employees and contractors will not perform any work in areas considered to be unsafe or install or connect any natural gas facilities that are, in the opinion of our employees or contractors, unsafe or not in compliance with LG&E’s requirements or governing codes and regulations. Both LG&E and Customer-owned natural gas facilities must be planned, designed, built, maintained, and operated in a manner that minimizes the risk of injury and property damage during construction and throughout the life of the facility.

Natural Gas Safety
It is important that users know how to safely use natural gas and care for natural gas appliances. One of the first steps to prevent accidents is to ensure that natural gas appliances and equipment have been properly installed, adjusted, vented and inspected. Appliances should be installed, serviced and repaired by professionals. Other safety precautions that should be taken include the following: • • • • • • • Follow manufacturers’ instructions for the installation, operation and maintenance of gas equipment and appliances. Since burning natural gas produces a high radiant heat, keep flammable materials (e.g., cloth, paper, paints, and solvents) away from appliances. Provide proper ventilation in areas around furnaces, water heaters, dryers, ranges, etc. Have routine maintenance performed on appliances to keep them clean and in proper working order. Ensure that all vents and chimneys are free from blockage. Clean or change filters on furnaces and dryers regularly. Maintain the gas lines that are located inside and outside the house to prevent leaks. The gas service lines buried from the property line to the house and all house line piping within the house are the responsibility of the property owner. LG&E will periodically survey all outside piping for leaks and will advise you if any maintenance is required on your portion of the service line. LG&E will also inform you of any corrosion that is discovered on any outside piping that is exposed to the weather and advise you to paint the affected area. Contact Kentucky 811 to determine the location of utility-owned service lines (including LG&E’s natural gas lines) before you begin any yard excavation; dial 811. This is a free service. Do not operate any electrical switches, equipment or appliances or use open flames if you smell a natural gas odor. Leaking natural gas can ignite.

What to Do If You Smell Natural Gas • If you smell gas and cannot find the source(s), immediately go to a location where no natural gas odor exists, such as a neighbor’s house, and call LG&E Natural Gas Trouble at (502) 589-5511 (outside Louisville at (800) 331-7370). A spark from using a telephone or cellular telephone inside the house could ignite the gas. If the odor is faint, get everyone outside and leave doors and windows open to ventilate the area. A faint odor of gas may mean that a pilot light has gone out and should be re-lit. If the odor is strong, evacuate the building immediately. Never use a telephone or cellular telephone, switch a light on or off, or light a match if you smell natural gas. Never look for a natural gas leak with a lighted flame or match. Do not try to re-light a gas furnace, water heater, or range.

Low, Elevated, Medium, And High Pressure – LG&E's classifications of operating pressures in the gas mains throughout its gas system are as follows: a. Low Pressure – The system operating pressure is essentially the same as the pressure delivered to each Customer’s meter and house line (i.e., 0.25 PSIG (seven inches Water Column (7” W.C.)). b. Elevated Pressure – LG&E’s elevated pressure systems operate at 2.0 PSIG at their sources of gas supply. A pressure regulator is required ahead of each Customer’s meter to maintain a constant standard delivery pressure of 0.25 PSIG (i.e., 4 ounces per square inch or 7 inches Water Column). c. Medium Pressure – LG&E’s medium pressure systems operate at pressures higher than 2.0 PSIG up to 60 PSIG. LG&E has several medium pressure systems operating at different pressures. A pressure regulator is required ahead of each Customer’s meter to maintain a constant delivery pressure that is normally the standard 0.25 PSIG. Higher delivery pressure can be delivered to the Customer if necessary, limited by the characteristics and operating restraints for the particular medium pressure system. d. High Pressure – LG&E’s designation for high pressure includes any gas transmission system or distribution system that is subject to operation at over 60 PSIG. Pressure regulation equipment is typically required both at the property line and ahead of each Customer’s meter to maintain a constant delivery pressure that may be the standard 0.25 PSIG or higher if necessary. Main – Gas system piping located in a public highway, street, alley or private easement that is used to distribute gas. Meter Loop – Piping provided by the Customer to accommodate the installation of the gas meter(s). PSIG – Pounds per Square Inch Gauge. A standard unit of measurement for describing the pressure of a gas or a liquid. SDR – Standard Dimensional Ratio. A numerical term used to describe the wall thickness of polyethylene pipe. SDR is derived by dividing the actual outside diameter of the pipe by the wall

thickness and is an indication of the strength of the pipe. Service Head Adapter – A transition fitting that adapts polyethylene gas pipe to steel pipe, in a manner in which the polyethylene pipe is shielded against damage from physical force and solar radiation, with all pressure containing metallic components located above ground. Standard Delivery Pressure – The gas pressure normally delivered to residential and small commercial Customers, which is approximately four ounces (4 oz) per square inch, seven inches (7”) of Water Column, or 0.25 PSIG. Tamperproof Gas Valve – A gas valve in which the core cannot be easily removed, either accidentally or intentionally, with ordinary hand tools. Tamperproof valves include a stem locking mechanism. Total Connected Load – The total heat input in BTUH for all gas burning appliances and equipment installed. W.C. – Water column pressure. A standard unit of measurement for describing the pressure that is expressed in terms of a water depth exerting an equivalent force. Typical gas pressure delivered to Customer's house piping 7" W.C., which is approximately 0.25 PSIG. The loss in gas pressure that results from gas flowing through a piping system is generally expressed in inches of W.C. drop.

After installing the meter loop and prior to testing the house line piping, contact the commercial service designer for service line and meter loop inspection. 8.10.B. The Commercial Gas Inspection Request Form, found in section: Supplemental Information, should be faxed to the Commercial Service Designer. 8.10.C. LG&E will visually inspect the Customer service line and meter loop to ensure compliance with applicable material and installation specifications. 8.10.D. After the visual inspection is completed and has PASSED the inspection, a hang tag indicating the service has been inspected will be left at the meter loop.

8.11.

Install and Pressure Test the House Line Piping 8.11.A. Make sure that the house line piping is ready. • To qualify for natural gas service, the house line piping system must be extended to an operable natural gas burning appliance(s) or to a plugged valve(s) at the proposed appliance(s) locations. Gas service will not be established by LG&E unless all gas outlets are secured or connected.



8.11.B. Pressure test the house line piping. • House line piping should be pressure tested to detect leaks prior to contacting LG&E for service connection. The Customer or Customer Representative should pressure test the meter loop and house lines to ensure there is not a leak. The pressure test is to be left on the houseline and meter loop until LG&E SR&O has completed all LG&E inspections. Strainers and Blow Down (Purge) Piping are to be tested with the meter and service line. Page 27 of 136

Install Piping Paddle Blinds or “Skillets” 1. Prior to pressure test, install pipe paddle blinds, also called “skillets,” upstream and downstream of regulators. Be sure to use skillets that are ASME rated equal to or greater than the pressures that will be experienced during the test. The skillets are supplied by the Gas Piping Contractor and should remain installed until LG&E SR&O has tested the house lines. Skillets should not be installed at the inlet and outlet of the meter. On Low Pressure (4 oz, 0.25 psig, 7 in wc) services that will not have a regulator, skillets should be installed downstream of the service valve. The Gas Piping Contractor is responsible for removing the “skillets” after LG&E SR&O testing has been completed.

SERVICE LINE SIZE & PRESSURE
17. Service Line Pressures
17.1. Service Line Pressures and Availability 17.1.A. Service line pressures are limited by the characteristics and operating restraints for the particular gas main serving the Customer service line. Service line pressures are typically consistent with the gas main pressure. 17.1.B. Gas main pressures vary by geographic region. Consult the Gas Commercial Service Designer for the pressure category of the gas main pipeline(s) in your area. 17.1.C. When the Customer has access to different operating pressure gas mains, the Company, in general, prefers the Customer service to be connected to medium pressure gas main pipelines. • The Gas Commercial Service Designer will be able to inform the Customer of the location and operating pressure of the main after the Load and Site Data have been submitted and reviewed.

17.1.D. In order to connect to certain high pressure distribution and transmission pipelines, special requirements must be met; not all Customers will be permitted to connect to high pressure mains.

18. Service Line Size
18.1. General 18.1.A. Depending on the nature and size of the gas load to be served, LG&E may require the extension and/or enhancement of one or more existing gas systems. 18.1.B. LG&E Account Representatives / Customer Coordinators must be contacted as soon as possible with loading information to initiate review by LG&E design personnel. 18.1.C. For commercial and industrial loads, the Gas Commercial Service Designer should be contacted for service line sizing recommendation, and meter loop design information. • The Gas Commercial Service Designer will recommend a service line size and path based on the information that he/she is given by the Customer. It is the responsibility of the Customer to ensure the Commercial Service Designer has the correct information by completing and submitting the Commercial & Industrial Gas Load Data Sheet. 1. Each gas service line must be of sufficient size to meet the maximum usage demand. This demand should be determined by adding the BTUH input of all connected appliances or equipment subject to simultaneous operation. The service line size required is dependent upon the operating pressure of the system to which it is connected, the length, as well as the maximum usage demand. Some allowance should be made for future installation of additional appliances.

GAS METER LOOP SIZE, CAPACITY & PRESSURE
33. Meter Capacity
33.1. General 33.1.A. To assure proper operation, each gas meter must be the proper size and type for the maximum gas demand and required pressure. The maximum gas demand is determined by adding the BTU input ratings of all gas burning devices that may possibly be operated simultaneously. 33.1.B. Furnaces, space heaters, water heaters, boilers, pool heaters, fireplace logs, gas lights, gas clothes dryers and gas generators should be included at their maximum input ratings. 33.1.C. Domestic kitchen ranges and outside grills may be considered to be 30,000 and 20,000 BTUH respectively as they rarely are operated at full capacity for extended periods with other appliances. 33.1.D. The Gas Commercial Service Designer will select a meter and meter loop that will satisfy the load demands that the Customer submits on the Commercial & Industrial Gas Load Data Sheet found in section: Supplemental Information. 33.2. Diverse Load Requiring Multiple Meters 33.2.A. Certain types of commercial and industrial loads may require multiple meters for the same building, serving the same Customer. • At the discretion of LG&E, customers with variable loads, such as process and heating that differ by an order of magnitude, may be required to install a meter manifold for multiple meters.

34. Meter Loop Delivery Temperature
34.1. General 34.1.A. The gas delivery temperature shall be assumed to be 60 degrees Fahrenheit. 34.1.B. The company reserves the right, for billing purposes, to correct as necessary the actual temperature in the case of large volume customers.

35. Meter Loop Delivery Pressures
35.1. General 35.1.A. Only LG&E representatives are authorized to make adjustments on the meter loop pressure regulation equipment. 35.1.B. Unauthorized adjustment of meter loop regulation equipment may result in civil or criminal action against the Customer, or a discontinuation of service. 35.2. Standard Delivery Pressure 35.2.A. Standard delivery pressure for commercial and residential services is 0.25 PSIG (4 oz. per sq. inch or 7 inches Water Column) to the Meter. Questions? Contact the LG&E Gas Commercial Service Designer at 502-364-8275 Page 63 of 136

35.3.

Delivery Pressure Higher than Standard Delivery Pressure – “High Pressure Delivery” 35.3.A. The Commercial Load Designer must review and approve all requests for “high pressure (higher than standard pressure) delivery”. 35.3.B. If necessary (i.e. due to equipment fuel gas requirements, process loads, or other design requirements), LG&E may have higher delivery pressures available. 35.3.C. Higher than standard delivery pressures or “high pressure” deliveries are limited by the characteristics and operating restraints for the particular medium pressure main to the Customer meter. 35.3.D. Commercial customers must demonstrate an operational need for “higher than standard pressure” delivery; delivery pressure higher than the standard will not be supplied to the Customer to compensate for inadequately sized houseline piping. 35.3.E. Customers with higher delivery pressures will be billed with a correction factor to account for the actual gas used during the billing period. Special requirements may exist for “higher than standard pressure” deliveries. 35.3.F. Reference the House Line section of this handbook for details on materials and joining pipe at higher than standard delivery pressure. 35.3.G. The following delivery pressures may be available (note discussion above): • • 2 PSIG, 2.5 PSIG, 5 PSIG, 10 PSIG, 15 PSIG Consult Gas Commercial Load Designer for pressure availability above 4 oz.

GAS METER LOOP MATERIAL, JOINING, SUPPORT, & PROTECTION
36. Meter Loop Assemblies
36.1. Meter Loop Assembly Fabrication 36.1.A. General • Each meter loop must be designed and installed to limit stresses on the connecting piping, meter, and regulator. • Customer house line piping is not permitted to be connected on the service line side of the meter. 36.1.B. • Configuration Meter loops should be fabricated such that the meter inlet piping is on the left, as the meter is read, and the outlet piping (house line) is on the right. Multiple Meters • • • Multiple meters shall be fed by a common meter manifold. Meter inlet piping shall not be constructed from the bypass piping of an existing meter. Multiple meter installations serving residential and small commercial Customers using standard meters (175 and 250 CFH meters) are required to be constructed with prefabricated meter loop assemblies to the greatest extent practical. See Drawing No. GCS 30-20-206, Typical Multiple Meter Installation Prefabricated Meter Loops, for a multiple meter installation using prefabricated meter loop assemblies. The house line side of each meter loop in a multiple meter setting must be permanently tagged with the identity of the unit or equipment served by that meter. Meter manifolds serving multiple commercial meters must have a master meter valve. Prefabricated Meter Loop Assemblies • Prefabricated meter loop assemblies are required for service to Customers utilizing standard meters up to 250 CFH nominal capacity (i.e., at 0.5” W.C. differential) whenever total demand and character of demand permit. For single meter installations reference the following drawings for piping details of standard house meters using prefabricated meter assemblies: 1. 2. 3. 4. • GCS 30-20-201, 1” Prefabricated meter Loop, GCS 30-30-201, Low Pressure Meterset Assembly, GCS 30-30-202, Medium Pressure Meterset Assembly 1 NPS x 20 LT with Regulator, GCS 30-30-203, Elevated Pressure Meterset Assembly 1 NPS x 20 LT with Regulator,

36.1.C.

• • 36.1.D.

For maximum gas demand of over 300,000 BTUH served from a low pressure (i.e., 0.25 psig) system, or where a bypass operation must be performed (such as for Page 65 of 136

Questions?

maintenance to a meter or pressure regulator) without interruption of normal operation, the prefabricated meter loop should not be used; field fabricated meter loops should be used instead. 36.1.E. Field Fabricated Meter Loop Assemblies • • • Use of welded service manifolds is encouraged to reduce the number of threaded pipe connections. Threaded pipe connections are prone to leaks over time. Meter loop piping serving rotary meters is required to be joined by welds. Line size valve and regulator connections should be flanged. For maximum gas demand of over 300,000 BTUH served from a low pressure (i.e., 0.25 psig) system though a one inch (1”) meter, a prefabricated meter loop shall be used if external bypass is not required. If an external bypass is required, a meter loop may be fabricated from standard pipe and fittings per Drawing No. GCS 30-20-204, 1” Meter Loop Field Fabricated. For any application in which an external bypass is required, and for any application requiring a meter of 375 CFH or more nominal capacity, the meter loop assembly will need to be fabricated using standard pipe and fittings. See Drawings Nos. GCS 3020-301, 1” Meter Loop with By-pass, and GCS 30-20-302, 1½ Meter Loop with Bypass. Drawings will be referenced and/or furnished by the Gas Commercial Load Designer for rotary meter installations and other field fabricated meter piping configurations when applicable. Meter loops for meters of 375 CFH or larger capacity in a multiple meter setting will need to be fabricated using standard pipe and fittings. See Drawing No. GCS 30–20001 for meter piping details for a typical multiple meter installation using standard fittings. The Company will furnish custom drawings when necessary for multiple meter installations.









36.2.

Meter Loop Gaskets 36.2.A. Do not use full face gaskets or semi-metallic spiral wound gaskets on the meter loop. • It is the experience of LG&E SR&O that full face gaskets are prone to leakage and are more difficult to replace than standard ring gaskets.

36.2.B. Gaskets must be non-asbestos, and listed for natural gas service • Gaskets consisting of a fiber blend with a nitrile rubber binder are commonly used on commercial meter loops. 1. Other gasket materials are permissible, but must be approved by LG&E prior to installation.

36.3.

Meter Loop Welding 36.3.A. Where welded meter loops are required, the loops must conform with the following: • Welded meter loops must be welded by a qualified welder using qualified welding procedures in accordance with the requirements of API Standard 1104, ASME Boiler and Pressure Vessel Code Section IX, or 49 CFR Part 192 Appendix C.

36.5.B. Bypass Valve Requirements • Bypass valves are required on meter loops one and a half inches (1-1/2”) and larger, and on some field fabricated one inch (1”) meter loops, in order to prevent major inconvenience or interruption of commercial process which would result from the shutting off of gas for meter change operations. 1. Generally, any meter loop that has a meter with a capacity of 425,000 BTU/H or greater at one half inch (½”) water differential will have a bypass. See Drawings No. GCS 30-20-301, 1” Meter Loop with By-pass, and GCS 30-20-302, 1½” Meter Loop with By-pass.

36.5.C. Inlet Side (or Service Side) of Meter Loop • • • Each new or reconstructed meter loop shall have an approved tamperproof gas valve of the proper size located on the inlet side of each regulator and meter. Each meter inlet valve or service side bypass valve must have a lock wing or other feature allowing the valve to be locked in the closed position. If served from a low pressure main, elevated pressure main, medium pressure main, or a high pressure main through a primary regulator, each valve must be designed and rated for an operating pressure of at least 100 psig. If served directly from a high pressure main without a separate primary regulator, each valve in a location subject to full service line pressure must be rated at least as high as the maximum allowable operating pressure for that main. Required pressure ratings, drawings, and general specifications will be provided or referred to by the Commercial Gas Service Designer. Contact the Commercial Gas Service Designer for these requirements. Each approved tamperproof service line valve shall be marked to show the manufacturer’s name or trade mark, the pressure rating with the letter “G” to designate gas, and the letter “T” to designate tamperproof.







36.5.D. Outlet Side (or House Line Side) of Meter Loop • Each valve on the house line side of a meter loop shall have a pressure rating of at least 100 psig, and shall be marked to show the manufacturer’s name or trademark and pressure rating with the letter “G” to designate gas. Page 68 of 136

49.3.C. Prohibited Locations • Underground 1. Steel pipe may not be buried beneath buildings, or be in contact with the ground beneath buildings, unless fully encased in a gas tight conduit. The Gas Operations Center in your area must be consulted for specific requirements.

49.4.

Polyethylene (Plastic) House Line Pipe 49.4.A. Specifications • Polyethylene pipe must comply with ASTM D-2513. The same material grades that are acceptable for service line installations are acceptable for house line piping. Polyethylene gas pipe may be used only outside of buildings and beneath the ground. An insulated copper tracing wire shall be installed adjacent to the polyethylene pipe with the ends terminating above ground at each end. Contact between the tracing wire and the polyethylene pipe should be avoided.



49.4.B. Joining • • • Joints may be made in polyethylene plastic using approved mechanical fittings or heat fusion. Properly trained and qualified installers should follow qualified written joining procedures. All transitions to steel pipe must be outside. Transitions may be made using service head adapters or anodeless risers in the same manner and type as used for service risers, or transition to mill coated and cathodically protected house lines may be made directly below ground.

Questions?

Contact the LG&E Gas Commercial Service Designer at 502-364-8275

Page 79 of 136

49.5.B. Specifications • Corrugated stainless steel tubing (CSST) systems must be tested, listed, and installed in accordance with ANSI LC-1/CSA 6.26, Fuel Gas Piping Systems Using Corrugated Stainless Steel Tubing. CSST may be used for installation of new house line systems or for addition to existing systems.



49.5.C. Joining • Only qualified installers, trained by authorized agents for the respective brands of CSST system, are allowed to install CSST piping systems.

49.5.D. Connections • Connection of the CSST to the meter outlet piping must be made using a suitable transition fitting supported by the outside building wall, such that the tubing is not exposed. See Drawing No. GCS 30-20-002, CSST House Piping, for a typical installation.

49.5.E. Labeling • The corrugated stainless steel tubing (i.e., Wardflex, Titeflex, GasTite, TracPipe, etc.) used on fuel gas manifolds shall be tagged and/or labeled in a fashion by plumbers so that the appliance served by the tubing is permanently and clearly marked.

49.5.F. Grounding • NFPA 54 states that each above ground portion of a gas piping system that is likely to become energized shall be electrically continuous and bonded to an effective ground fault current path. Gas house line piping shall be considered to be bonded when there is a continuous metal connection to appliances that are connected to the equipment grounding conductor of the circuit supplying that appliance. The NEC allows the appliance grounding provision to serve as the pipe grounding provision so a separate bond wire is not generally required. However, nothing prohibits additional bonding especially if this is requirement of the CSST manufacturer. If additional grounding of the CSST houseline piping system is required, LG&E recommends installing an approved grounding clamp and a bond wire from the grounding strip in the electrical panel to the nearest section of each continuous section of CSST piping. The bond wire should be sized in accordance with Table 250.66 of the NEC. The grounding connection would have to be made by a qualified electrical contractor and would be subject to an electrical permit and inspection. LG&E does not recommend grounding the CSST piping to a separate ground rod. This would establish a separate independent building ground and would violate the requirements of the NEC. There is a concern about separate grounding systems and the potential to injure someone in contact with two separate grounding systems during a fault, lightning strike, etc.







49.5.G. Prohibited Locations • CSST may not extend into the fireboxes of fireplaces designed to burn solid fuel. CSST or fittings may not be installed in any manner or locations where they will be subjected to heat from solid fuel fires. Page 80 of 136

55.2.

Pipe Surface Preparation and Coating Installation 55.2.A. Aboveground Piping • • • Clean the piping surface of all dirt, oil, grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent. Remove all paint that is not tightly adhered. Remove rust and loose mill scale. Power tool cleaning is recommended. However, hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface. Paint the piping surface with an acceptable aboveground coating. The proper protective clothing, gloves and mask should be worn during the surface preparation and coating installation process.

• •

55.3.

Underground Piping at Joints and for Defects in Coatings 55.3.A. Poly-Butyl Tape • • For defects in the coating, remove all damaged coating to a point where it is firmly bonded to the pipe. Clean the piping surface (i.e., the welded joints and the defects in the coating) of all dirt, oil, grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent. Remove all rust, paint, and loose mill scale. Power tool cleaning is recommended. However, hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface. File or grind smooth all sharp edges or burns to prevent protrusion through the PolyButyl tape. Apply a thin uniform coating of primer to the clean piping surface and to the mill coated piping surfaces within the area to be wrapped. The primer used shall be compatible with the coating. The piping surface must be moisture free prior to the priming procedure and remain moisture free throughout application of the Poly-Butyl tape. Allow primed piping surface to dry to a “tacky” stage before application of the Poly-Butyl tape. Apply the Poly-Butyl tape over the weld joint or defect area by using a cigarette wrap. A cigarette wrap consists of using pre-cut strips of Poly-Butyl tape equal in length to the circumference of the pipe plus a minimum of four inches (4”). Apply the Poly-Butyl tape over the entire area (including the weld joint) to be wrapped by spirally wrapping the Poly-Butyl tape around the pipe using a continuous 50% overlap of tape. The Poly-Butyl tape should be applied under tension. However, the last turn should be applied without tension. The tension in wrapping should be enough to obtain conformability to the surface being coated. The Poly-Butyl tape should then be cut on the downside of the turn and pressed into position. For questions or additional guidance involving the surface preparation and/or the installation of Poly-Butyl tape, contact the Gas Operations Center in your area. Page 86 of 136

55.3.B. Wax Tape • • For defects in the coating, remove all damaged coating to a point where it is firmly bonded to the pipe. Clean the piping surface (i.e., the welded joints and the defects in the coating) of all dirt, oil, grease, moisture and other foreign matter. Oil and grease should be cleaned using a cleaning solvent. Remove all rust, paint, and loose mill scale. Power tool cleaning is recommended. However, hand tool cleaning (i.e., wire brushing) is acceptable. Use a cleaning solvent as required to ensure a clean piping surface. File or grind smooth all sharp edges or burns to prevent protrusion through the underground coating. Apply a thin uniform coating of primer to the clean piping surface and to the mill coated piping surfaces within the area to be wrapped. The primer used shall be compatible with the coating. While it is preferred that the piping surface be moisture free prior to the priming procedure, a damp or wet surface is tolerable when applying wax primer and tape. Where moisture is present, rub and press primer into the piping surface, displacing the moisture and ensuring that the primer adheres to the piping surface. Apply the wax tape by spirally wrapping the wax tape around the pipe using a 25% overlap (e.g., using a four inch (4”) inch wax tape, a one inch (1”) overlap is required). Press the wax tape into place making sure that no air pockets exist and that the wax tape is in contact with the piping surface. Press and smooth out the lap seams to ensure that the laps are sealed. For questions or additional guidance involving the surface preparation and/or the installation of wax tape, contact the Gas Operations Center in your area.

Coating Damage Prevention 55.5.A. Care should be exercised in the handling of coated pipe. 55.5.B. The bottom of the ditch must be free of rocks or foreign objects that may damage the coating. In addition, backfill shall be free of rocks or debris that may damage the coating. For more detail on backfill and trench bottom conditions, refer to Section 3.10.2 a. – Backfill and Trench Bottom Requirements.

56. Corrosion Prevention - Electrical Isolation
56.1. General 56.1.A. In order for cathodic protection to be effective, all protected pipe must be electrically separated from any electrically grounded metallic structure or piping.

56.1.B. Dielectric couplings, dielectric unions, or dielectric flanges may be used at each point where the protected piping extends out of or into the ground.

57. Corrosion Prevention - Anodes
57.1. General 57.1.A. Cathodic protection can normally be provided to the coated and electrically isolated underground steel piping by means of a magnesium anode. 57.1.B. Magnesium anodes have an insulated lead wire that must be electrically attached to the protected piping by thermite welding, brazing, or with an approved mechanical grounding clamp. 57.1.C. The connection to the piping must be coated with approved mastic or with tape and primer in the same manner as a joint or defect in the coating. 57.2. Anode Spacing 57.2.A. For maximum effectiveness, one five pound (5 lbs) standard potential magnesium anode should be used for each 50 foot (50’) section of underground steel piping. 57.2.B. To the extent practical, the anodes should be evenly spaced over the length of the piping being protected. 57.3. Anode Installation 57.3.A. Anodes should be installed vertically at least three feet (3’) away from the piping with the top of the anode even with or lower than the elevation of the buried piping. See Drawing No. GCS 50-20-801, Vertical Installation Anode and Test Station, for recommended anode installation method.

SPECIAL NOTICES
58. Notice Regarding the Installation of Gas Fired Electric Generators
58.1. General 58.1.A. In many cases, the installation of gas fired generators on an existing residential houseline will require a delivery pressure increase to higher than standard delivery pressure. Not all gas systems will be able to support an increase in customer delivery pressure (reference definitions of Low and Elevated Pressure Systems). 58.1.B. Customers should contact the Commercial Load Designer to determine if the system can support the generator load. 58.2. Installation Requirements 58.2.A. Reference manufacturer’s recommendations for installing house line regulators.
