I am having a whole house standby Generator installed. The new gas line would be a direct line from the gas meter. When speaking with the plumber, he said as long as the new gas line is done completely outside, the only line they pressure test is the one they just drew. I live within the town of Hempstead regulations and was trying to validate this. He said once the line goes inside, they have to test every line/appliance. I wanted to know if this was correct or not.
Make sure you check the specs for noise ordinance for the standby generator. My friend put one in her backyard and due to the zoning for noise, (i.e. couldn’t be within x feet of the fence) it was smack in the middle of the yard.
The pressure test is dependent on what gas appliances you have. If you only have a boiler, should be fine. If you have a gas stove, dryer, etc. then yes, it can get complicated if, for instance, the line is located on the opposite side of the house from the generator. I installed a Generac 22KW in ToH this year, if you have any questions, happy to help.

The generator creates engine exhaust, so it needs to be x feet from a window also. You wouldn't want to be blowing exhaust near the neighbors either. It's probably no louder than a riding mower.

They put a larger pipe on the gas meter that splits and feeds the generator. We have a 16KW Generac and there's no effect on gas appliances (stove, water heater, forced air heat heat) when it is running. If there was it would defeat the purpose of having a standby whole house generator. There are several Generac generators in our subdivision. We had no problems with the township. The company that did the installation knew their stuff. They ran an electric line through the garage and crawl space from the opposite side of the house, to allow the generator to be close to the gas line. It's on a timer and runs the motor for 5 minutes once a week at the same time. During an outage in the middle of the night it went on for two hours and then tuned off when power was restored. We slept through it all.
Even with the device outside a potential gas leak can be a dangerous thing. Unless you are doing this under the table I would ensure that they have permits and contact the town to find out what inspections/final inspections are required. Is this plumber willing to put his statement and his name & business in writing so down the road if his statement is found untrue you have documentation to sue him?
