1. Correctly mixed LP to Air will NOT smell like LP at the exhaust.
2. You do not state model of furnace, but if the furnace has NEVER been pulled and checked/cleaned in 30 years, the odds are the burner needs cleaned and there may be some insect nests inside restricting the fresh air intake for complete LP air combustion.
3. Getting low in the LP tank does NOT increase the amount of ethyl mercaptan (LP odorant agent) in the LP system.
4. If you have the NT series of Suburban, then the cast iron burner is probably clogged with rust. To fix this model burner, you pull the burner and use a Hack Saw blade to clean out the slots in the burner. The NT also has a screw type air adjustment. If running RICH (lack of air) you should also see black soot build up on the outside exhaust vent assbly.
5. ALL LP sold and produced in the USA and Mexico has the Odorant added at refinement. There is NO LP sold without the odorant. Doug
