First off, welcome to SMF.
There are a lot of Masterbuilt owners here including myself.
If you will search and read all the threads on "Masterbuilt" you can come up to speed real quickly.
Is your unit the old or new version? The new ones have a vent at the top the old ones do not....there are other differences also but none as important as having the unit vented on top.....You do not want a lot of smoke coming out the top just enough that you can tell there is smoke
Good advice is to subscribe the email letter that Jeff has posted here for gathering the basics
Then read all the threads in the "Electric smoker" section on using the MES
Most of us do not soak the chips at all just add 3 or 4 chips about every 30 minutes...that's all it takes
Good luck and good smoking
