It's turned off at the tank till we can figure it out. Don't have a basement and the space under has venting.If it's leaking under ground near the house, might want to check in the basement or crawl space for any gas. That house in some small town in CO that blew up when the dudes were putting in a new water heater due to natural gas leaking from a line off a gas well that ran near the house leaking gas into the dirt and it seeping into the basement really makes ya' think about that sort of thing.
