UDS temperature control

post #1 of 4
Thread Starter 

I recently finished building my UDS. I am smoking ribs and chicken as I write this. I installed three 3/4" nipples near the bottom of the UDS with one of them having a 3/4" valve on it. I have the 2" and 3/4" bungs open in the top head. I am burning Kingsford original charcoal with mulberry wood. I am having a devil of a time controlling the temp. I thought I had it set up with two vents closed and the valve part way closed and then I went out to check and the temp was about 200 F. I am trying to hold 225-235 F. So, I am in the recovery mode right now. Should temp control be this touchy? Maybe this is why folks buy automatic temp control equipment.

Would appreciate any suggestions. Maybe I am trying to control the temp too close.

air flow is the key...try and keep your exhaust vents open and adjust your temp with the air intake valve...if it gets to hot in the chamber close down the exhaust vents bit by bit to help get the temp you want

I'm new to my UDS but in general this is the rule you want to use....also remember controlling temp on a uds is like turning the takes a minute.


When i get to about 25-50 degrees from my target temp is when i back way off on the air.  It won't stop on a dime so if you wait until you reach your target to back off you will way over shoot it and will take time to slowly get back down to where you want it.

With regards to temp controllers such as the Guru...they are great.  They will basically puff air intermittently when it comes with in certain perameters of the target.
