General requirements.

(1) 

Fuel gas piping systems shall be installed and maintained so as to remain gastight, safe and operative under conditions of use.

Fuel gas piping systems shall provide a supply of gas sufficient to meet the maximum expected demand of the installed gas-burning appliances connected thereto.

B. 

Shutoff valves.

(1) 

Gas piping systems shall have at least one accessible means for shutting off all gas supply, and such means shall be clearly marked with a sign reading "Gas Shutoff."

(2) 

An easily accessible shutoff valve or cock shall be provided in the piping in close proximity to and ahead of every gas appliance installed after the effective date of this chapter.

C. 

Service equipment for gas supplied from utility mains. Gas services, gas meters and gas pressure regulators shall be located so that they are protected from damage. In multiple dwellings and business units, gas meters shall be located in a fire-resistant room, vented directly to the outside by a permanently installed louvered ventilator and free from a source of ignition. There shall be no storage of materials or equipment in the gas meter room. In no case shall such equipment be located in a boiler room.

D. 

High-pressure gas. Any service connection supplying gas at a pressure in excess of one pound per square inch gauge shall be provided with a device to reduce such pressure to not more than 1/2 pound per square inch gauge prior to entering the meter, except where such service supplies equipment using gas at high pressures.
