Propane smell when furnace is running - Suburban SF-30F

The trailer is 14 months old, I was just generalizing. :) We're the second owner. Maybe we're wrong, maybe it is exhaust -- now I'm starting to second guess. It's pretty strong and it only happens when we run the heater.

The heater is now sitting on our dining room table. This is how much it's bugging us! Any advice on what we should look at? I have a Symbion Portable Propane Natural Gas Leak Detector in my Amazon cart ($23). Anyone ever used one of those?

You said the trailer is only ABOUT a year old. . . Find out how old, and IF your the original owner you may be able to get it replaced under warranty if it needs to be...

Call the dealer, or manufacturer.

Don't mess with possible propane leak, or smell

Man, you need to get someone in there with some detection equipment if you are sure it is propane.

i could understand exhaust, but propane i don't know.

The heater works -- but we've been running it for days and the smell is still there. I suppose it could be exhaust, but we've been RVing for 25 years and we're pretty familiar with the smell of propane. It does not set off the gas detector, but the smell in the RV is strong enough to be annoying. We're leaning toward the heater itself as we're almost out of ideas. However, I sure as heck don't want to spend $500+ on a heater unless I'm SURE. Thanks for the suggestions. How can we tell if there is a hole in the heat exchanger?

I hope you don't have a hole in your heat exchanger.

If the furnace is working and you've checked for leaks it may be contaminates burning off the heat exchanger. Our furnace smell very strong for about an hour when first lit for the season. It is very strong, take your breath away strong, so we open the window and turn a vent on. Usually has a slight smell for a few more cycles and then usually gone by the next day.

Verify the smell is propane, go out to the tank, disconnect the hose and smell. If the smell is the same, you'll need to keep looking for a leak.

Does it set off your gas detector??

You might want to verify no rotten rodents in the ducting also.

Mine does the same thing with the WH running. I think you're smelling the exhaust.
