 Gas Smell Tankless Exhaust
Author: DanBlum1946 (NC)

From my tankless water heater, I get a short, small smell of gas (mercaptan) right at the outside exhaust flue just when the unit fires up. I was following up on a friend's report of such a smell, so I had my nose only inches from the flue. I doubt I would smell it even a foot away. Is this to be expected?
