Kevin H Posted January 17, 2016 Report Share Posted January 17, 2016 I have an Atwood Hydro Flame furnace in my '13 Montana. We've had the rig since new, two years this past October. Just recently I'm noticing a faint exhaust smell inside when the furnace is running. I do NOT smell propane, just the exhaust smell of burnt propane - like a propane fueled forklift. All appears to be working fine, just the smell. My propane detector tests fine and is not alarming. I looked into the exhaust outlet and it is clean, no evidence of mud daubers or other critters. The boss says she does not smell it. She ordinarily has a pretty sensitive sniffer. I can smell exhaust pretty good outside when it is running, which I would expect. No windows near the furnace. Wind is pretty calm here. Furnace is in basement. Mounted upright rather than horizontal. Any ideas? Link to comment Share on other sites More sharing options...
