What is the io/od of the chimney on a 640?

3" OD approx. 2 3/4" ID

Hey Herb, just got the 640, You are going to have to update your cheat sheets. The chimney is 3" OD not 4.

You are correct. I posted that from my phone and didn't check it after hitting the post button. I have corrected it. Thank you.

Hehe
