Yeah, it has to do with sulfur content and the source of one's gas. I'm not up on all the different standards with NG versus LP or even what the current, accepted standards are. I live in a small town that is behind the times. We don't even have inspectors to enforce our codes. Even if we did, I wouldn't trust 'em, based on what I've seen from our city engineer.
