So I use this modification on three of my smokers. I use it on the Mini, the UDS and My GOSM. The smoke generator that I use is the 12" & 18" AMNTS tube smokers from A-Maze-N Smokers. These were made to smoke pellet, but you can also get chips to smoke in them too. My mail box has a hole in the front that is just a bit bigger than the tube. The rear exhaust is 3" dryer vent, that in turn gets reduced down to either a 1" or 3/4" threaded nipple. This screws into the air inlets on the the UDS, Mini, and a modified port I have on the GOSM.
The pvc reducer is just slip fit together. This allows you t oscrew the nipple into the valve and then slip the nipple into the reducer
Reducer parts
Nipple threaded into valve.
I should note that on the Mini I only use this during cold smokes since the valve gets too hot during hot smokes. On the UDS and the GOSM I can connect as the inlets do not get hot while hot smoking. I am working on a metal reducer to use on the mini.
