Furnace Exhaust question

Thanks all. Apparently I need to be much more specific in my posts. :) I know propane is odorless and that what I smell is the additive. This is however the first time I have seen or heard anyone mention that you could smell the additive without there being excess propane in the air also.

I know nothing about this at all, but sounds like incomplete combustion.

This was my first thought as well as I had this problem with my water heater before I replaced it. This is why I was wondering if there were adjustments that could be made or not.

Oops, but I actually would like to train it to clean and drain itself out. :)

Two: If the tank is near empty, sometimes the odorant concentrates

Actually I was scraping the very bottom of one my 30lb tanks. I just noticed that my regulator switched over to the other tank this morning. I will definitely recheck the exhaust tonight when I run the furnace and see if the smell is still present. Thanks for that.

This additive does not fully combust and gives an odor to the exhaust, so what you are smelling is the exhaust.

Interesting. So you've noticed this with your rig as well? It sounds reasonable to me anyone wanna second?

Thanks everyone!
