I don't know the company name but I did talk with one of "them" a few days ahead of time. Did not seem too swift.
There IS a ball valve there in the gas line but its out of view. There WAS also a rubber flex line that was supplied but not installed, why I have no idea.
There is one thing thats missing here as well I think. There is no "dirt pocket" in the gas line at the inlet of the generator. Given I don't know much about gas code, but I always thought there had to be one right at the appliance? There is one like 5 feet upstream where the fitter changed direction of the pipe and incorporated a dirt pocket there, but what good is that going to do if the last 5 feet of line start to accumulate some moisture or rust??
Going to have to look that one up too!
