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?
