Mine is 8" ID x 18 inches long. Also the blower is choked back a great deal. I would guess it is putting out 15-20CFM at most. I tried a higher output blower with a bypass valve that I was using as an air curtain. Just could not stand the noise and it was very hard to adjust. I burned up a 100lb bottle of propane in about 2 hours. Not the results i wanted. Went back to the drawing board and just copied Wayne Goddards design. Works great and lasts a long time. I have made some modifications to allow more control at lower temps but it still comes up to temp fast and is very economical.
PS been using it for over 8 years now.
