Low temperatures in new UDS build
I've just finished my first UDS build, and fired it up after a seasoning burn. I found that the temperatures achieved were well below what I was expecting.
To get to a 350f grill temperature, I had to have all 4 of my 3/4" nipples wide open.
The lid is the standard one from a Weber kettle, with the vents wide open. The ambient temperature was 30f, and the whole charcoal bed was alight.
Adding a heat-deflecting plate a couple of inches above the brazier dropped the grill temperature by 120f.
The only things that I can think of that could restrict the temperature are: the ash pan sides obstruct the direct path between nipple and brazier; and the brazier sides are perforated metal, not expanded metal.
Any advice much appreciated.
