There is a thin layer of soot inside my Uuni 2S. Is this normal?

There will always be a light layer of soot from burning but you shouldn’t experience much when using our pellets or other hardwood pellets. If it feels like there is too much smoke, it's a sign of incomplete burning. 


  • Lower the hopper level and add fewer pellets. 
  • Tap the hopper with the scoop to ensure all pellets have moved down the hopper and are lit from the hot pellets below.
