JUMP TO FULL CODE CHAPTER
The maximum operating pressure for piping systems serving appliances
designed to operate at 14 inches water column (3.5 kPa) inlet
pressure or less shall be 2 pounds-force per square inch gauge
(psig) (14 kPa) unless an overpressure protection device
designed to limit pressure at the appliance to 2 psig (14 kPa)
upon failure of the line gas pressure regulator is installed.
