What model do you have? The Smoke N Grill or the Gourmet Smoker?
For the Gourmet, see here: http://www.bbq-brethren.com/forum/sh...d.php?t=104545
For the Smoke N Grill, see here: http://www.randyq.addr.com/ecb/ecbmods.html
I assume since you mentioned Randy, you've already seen the 2nd link?
I'm also assuming you have the Smoke N Grill by your description?
EDIT: After looking at the link you provided, I'm SURE you have the Smoke N Grill. I'm not going to be much use, having never used one of those.
