Well, other than the fact that it does burn off, no. Had a inaugural brew session on it last night. Pretty fun stuff. Got the wiring done up just in time. Not perfect, but did the job. Also first time on house NG! Those burners are amazing. My buddy and I were in awe at how fast they headed up the mash water, boil, etc. 4" below the pot seems about perfect. They just crank out the heat. All in all it went well last night.
