Notwithstanding the provision of § 51.56, the piping from the gas meter of the Natural Gas System through the foundation of the building where gas is to be used shall be rigid pipe of not less than ¾-inch inside diameter. Inside the structure the rigid pipe shall be increased to not less than one inch inside diameter. The rigid pipe shall be run to all gas appliances permanently affixed to the structure housing the same, such as hot water heaters and gas furnaces whether of the basement, floor or wall type. In the installation of space heaters, clothes dryers and gas ranges which are ordinarily regarded as personal property rather than something affixed to the real estate or a permanent part of the building housing the same, the rigid pipe shall run, either to and be connected with the gas appliances or, at the option of the owner, within four feet or less of the gas appliances and then connected to the gas appliances by flexible copper tubing approved by the American Gas Association. The rigid pipe shall be used not only through the foundation of the building but also through any floor before any flexible copper tubing is connected therewith. A cut-off valve should be installed in the rigid pipe as nearly as practical to each gas appliance so that gas may be disconnected from each gas appliance separately without disconnecting the gas from the other gas appliances.
