Like the title says, my water heater closet smells like gas. It's a pretty strong smell once I open the door. I checked the exhaust and it isn't clogged, turned the heater on hotter so it would ignite and I checked out the ignition bar and didn't notice any spots not burning so it appears to be burning efficiently. I've done a soap test before and didn't find any leaks. I'm going to spray again just to double check. I haven't checked anything else and am not sure where to go from here. I've got the door propped open for now so it'll get good air flow. Oh yeah, and I did check out the vents in the door (top and bottom) and they are both free of obstructions.
