Chimney

[booboo]

I have a Yoder pellet smoker and it has an adjustable chimney. I have no idea if I should close it; leave it wide open or what. Can someone tell me how it works?

I am not expert but my understanding is leave it wide open during smoking and close it as a rain cover when not.

Not sure about the Yoder, but on a Treager, the chimney cap should be open 1 inch
