So... What size flex pipe/90 degree angle did you all use?
Thanks! I'm really looking forward to participating in these forums. I've been smoking on my Webber Genisis with makeshift chip boxes and water pans for several years now and my wife got sick of watching me drool over having a "real" smoker! I'm looking forward to a great summer.
I used a 4' to 3' adapter and a 3' elbow. The hole on the cooking chamber to the chimney is oblong so that's why I used the 4' adapter. I put it through the hole from the out side, cut slits about 1' or so all the way around it, bent it flat against the end and then used Rutland high temp silicone between the cooking chamber and chimney. Sealed it just fine.
The fire box is a must, I made mine for my old smoker so it is12" x 12" x 6", have to snake it around to get it in, might wanna make yours a little smaller. Maybe a inch or so smaller.I might have got lucky but with the extended chimney I have only 3 degree difference from side to side.
You will want to use the Rutland on the seams around the fire box, I had 1/8 gap between the top and bottom where it bolts together.
Congrats on it! I enjoy mine, did a few practice burns to learn it first, now smoking on it and loving life!
