Just installed a propane 30K BTU ventless gas heater on my enclosed-but-far-from-airtight porch; produces great heat but there's a smell that my family finds quite obnoxious. The flame pattern is by-the-book blue, the paint/oiled surfaces that were going to burn have been burnt , the smell is apparently some by-product of combustion, but what? I'm of the opinion it's the combustion of the mercaptan that's added to LP to make it smell, but have found no references to that possibility in hours of internet searching.
No CO2 or CO problems.
Happens as soon as we fire the thing up, it's not an oxygen-shortage issue.
Have not had the LP pressure tested at the heater, but it's the same line that feeds my furnace and cook-top and both are operating fine. Heater is dual-fuel, curently running on LP.
The cook-top is a 4-burner unvented unit and we don't notice the same smell when cooking even with 3 burners going at the same time.
Any ideas?
