I currently have a natural gas line running to my patio but I have no idea how to tell if it's active or not? I know my water heater is running on natural gas. I have found the piping running through my attic but not sure how/what to test it with. I'm wanting to possibly get a Blichmann burner and want to ensure i can use my natural gas line!
