Are regulators required on natural gas manifold? There’s one at the meter. I have one at my personal house. Inspected a house without one…
Why do you think you would need one?
It depends on the equipment attached to the manifold (and there are none there).
There’s a supply to the gas range.
It depends on a number of things. If this a high pressure system? If you don’t know it’s best contact a local plumber.
For residential, here will be a regulator on or upstream of the NG meter. Commercial applications may have different placements.
Did you call out the receptacle? No cover, some type of cord end coming out the side and cut off, etc
