(a) Service lines shall not be of a size smaller than that of the gas company's service line connection.
(b) Standard weight wrought iron or black steel pipe shall be used for all service lines.
(c) Galvanized pipe shall not be used for underground service lines.
(d) All screw fittings shall be black malleable iron of the banded or beaded type. Bushings, unions, screw couplings, all thread nipples, cast iron fittings, or galvanized fittings, solder type fittings and connections shall not be permitted in the service line.
(e) Where more than one length of pipe is required, welding or a compression coupling of the Dresser type (Style 38), or its equivalent, with armored gasket, shall be used to join the lengths of service pipe.
When welding is used, the welding procedures and the quality of welding shall conform to the procedures and processes in Pressure Piping Systems Code 4101:8 of the Ohio Administrative Code for welds on piping systems intended to operate at less than twenty percent of the specified minimum yield strength.
(f) The customer service line shall be laid on undisturbed or well compacted soil in a separate trench, avoiding sewers, water pipes and conduits, and shall not run through septic tanks or leaching beds. It shall not be laid on a bench or offset of a deeper trench. The trench shall be graded uniformly to provide solid and continuous foundation for the pipe and shall be deep enough to provide at least twelve inches of cover over service pipe.
(g) The service line shall be installed in a continuous straight line and at right angles to the building line. Turns consisting of ninety degree ells and nipples shall be used where underground vertical offsets are required. Bends in pipe shall not be permitted.
(h) Where the service line is laid under a portion of a building, the line shall be cased from a point at least two feet beyond the foundation entry and, if a riser is involved, to a point on the riser at least six inches above the floor. The ends of the casing shall be sealed by welding to the service line. A vent line shall be provided from the casing to a point outside the building.
(i) The service line may parallel the foundation wall, at a distance of not less than three feet from the foundation, to a point opposite the meter setting location. Such a line shall not parallel the foundation or building wall for a distance of more than fifteen feet. The meter shall be installed on the outside of the building and located so as to comply with above conditions.
(j) The service line shall not be laid under concrete or other hard surface walks or driveways except where it may be necessary to cross under such walks or driveways and except where such walks or driveways extend from curb to foundation wall and the full width of the property such as service stations and places of business. Where a service line is installed under these conditions, a vent shall be installed over the line near the foundation wall.
Where a riser passes through a walk or driveway, it shall pass through a sleeve or other means of providing a space between the riser and the walk or drive. This provision shall apply to the construction of a walk or driveway around an existing riser.
(k) Each length of pipe shall be examined before connecting, and dirt or obstruction removed. The burr left by the cutting tool shall be reamed off. Pipe and fittings shall be examined for condition of threads. Pipe dope or thread lubricant shall be used sparingly and on male threads only.
(l) When a service line terminates at an outside meter setting, the inlet riser shall include a tee ahead of the meter stop. The side opening of the tee shall be plugged and the head of the plug used to close this opening shall be drilled for seal wire.
(m) A suitable vent terminating in an insectproof and rainproof fitting shall be provided for all service pressure regulators. The vent shall be the same size as the vent top on the regulator. Pressure regulators supplied from medium or high pressure mains shall be installed outside of the building.
(n) The service line trench shall not be backfilled until after the line has been inspected by the gas company supplying gas to the premises. The trench shall be backfilled within twenty- four hours after approval of inspection.
No heavy weight or heavy material, such as large stones or concrete blocks, and no cinders or slag shall be placed on the service line or in the fill over the service line.
No heavy equipment shall be run over the service line or trench after it has been backfilled.
(o) An approved tamperproof stopcock (a stopcock designed and constructed to minimize the possibility of the removal of the core of the cock accidentally or willfully) shall be installed in the service line ahead of the regulator and the meter inlet. All stopcocks over two inches shall be of the lubricated type.
Where two or more meters are manifolded at one location, a master cock controlling the gas supply to all meters must be provided in addition to the cocks controlling the supply to each meter.
On multiple meter installations, each meter stop shall be plainly marked by a metal tag designating the part of the building being supplied.
(p) All piping from the point where the house line enters the building to the meter shall be exposed and accessible.
(q) Gas meters shall be installed as near as practicable to the point where the house line enters the building and shall be so located as to be readily accessible for examination, reading, replacement and where they will not be subjected to damage, excessive corrosion or to extreme temperatures.
All gas meters shall be located outside and at a minimum of three feet from any electric meter and a minimum of five feet from any steam or other harmful exhaust. The meter shall be protected by a cover which can easily be removed when needed and also shall have a properly located opening for reading.
No meter shall be removed, connected or reconnected except by the gas company supplying gas to the premises.
(r) Each building served with gas shall have a separate service line, except that a separate line shall not be laid for gas service to a garage, workshop or other building on a lot where there already exists a service line to the residence or main building of the customer.
For single-family dwellings, and for doubles, duplexes, apartments, terraces or flats having a basement common to all tenants, one customer service line only is required and meters shall be manifolded at one location. Where the gas main is located in the alley, the curb cock and box shall be located adjacent to the rear property line. Where the gas main is located in the roadway or between the curb and property line, the curb cock and box shall be located adjacent to the front property line.
In special cases where no location is available for outside meter setting, the Building Official may issue a written approval for an inside meter setting along with the approval of the gas company. In this case the gas company shall supply the instructions to govern this meter installation. (Ord. 412. Passed 3-23-59.)
