G2415.6.1 Buried building piping. Piping shall not be installed in such a way as to be in contact with the ground or fill under a building or building floor slab. When the administrative authority determines that it is not practical to avoid the installation of building piping that is buried or laid under a floor slab, the gas piping shall be encased in wrought iron, plastic schedule 40 pipe or steel pipe. The casing shall extend into a normally usable and accessible portion of the building. At the point where the casing terminates in the building, the space between the casing and the gas piping shall be tightly and permanently sealed with materials such as commercial casing seals, plastic, foams, cement, tars or asphalt materials. The casing shall extend at least 4 inches (102 mm) outside the building and be vented and installed in a way as to prohibit the entrance of water. The entire installation shall be such that the gas piping can be readily replaced without damage to the building.

E.

Section G2417.1.1 of the 2012 Edition of the International Residential Code for One- and Two-Family Dwellings is hereby amended by deleting Section G2417.1.1 and substituting the following:

G2417.1.1.1 Accessibility for inspection. Excavations required for the installation of underground piping shall be kept open until such time as the piping has been inspected and approved. If piping is covered or concealed before approval, it shall be exposed on the direction of the building official.

G2417.1.1.2 Required inspections. The building Official shall make the following inspections and shall either approve that portion of the work as completed, or shall notify the permit holder wherein the same fails to comply with this code.

G2417.1.1.3 Rough fuel-gas piping inspection. This inspection shall be made after gas piping authorized by the permit has been installed and before such piping has been covered or concealed or a fixture or appliance has been attached thereto. This inspection shall include a determination that the gas piping size, material and installation meet the requirements of this chapter. It shall also include an air pressure test, at which time the gas piping shall stand a pressure of not less than 10 pounds per square inch gauge (68.9 kPa gauge) and shall hold this pressure for a length of time of not less than twenty (20) minutes, with no perceptible drop in pressure. The test shall be made using air pressure only, and be verified in writing by the gas/mechanical contractor on forms authorized by the Department of Codes Administration witnessed and signed. Retest or additional certification, in special situations may be required by the Director of Codes Administration or by his/her duly authorized representative. Necessary apparatus for conducting test shall be furnished by the permit holder.

G2417.1.1.4 Final inspection. This inspection shall be made after piping authorized by the permit has been installed and after all portions thereof which are to be covered or concealed are so concealed and after all fixtures, appliances and shutoff valves have been attached thereto.

G2417.1.1.5 Other inspections. In cases where the work authorized by the permit consists of a minor installation of additional piping to piping already connected to a gas meter, the foregoing inspection may be waived at the discretion of the building official. The building official shall make such inspections as deemed advisable in order to assure that the work has been performed in accordance with the intent of this code.

The test shall be made using air pressure only, and verified in writing by the gas/mechanical contractor on forms authorized by the Department of Codes Administration witnessed and signed. Retest or additional certification, in special situations may be required by the Director of Codes Administration or by his/her duly authorized representative.
