Hello, does anyone know if any training is required for technicians to work on gas pressure regulators that are attached to a propane line for residential use?  I have a pretty big generator at my home in PA (38 kW) that uses propane to fuel it.  The generator has a Maxitrol regulator attached to the fuel source line which is outside right next to… (Show more)
