We designed SmokeFire to direct ash (and grease) downward, avoiding food as much as possible. Wood naturally produces ash while burning, so there is a possibility with any pellet grill that some ash is found inside and outside of the cook box. Weber Engineers took great measures to uniquely design a pellet grill that directs ash down and into an enclosed system, so that very little ash should ever reach the cooking grate area.
You'll notice more than usual the first time your barbecue is used, and that is okay. We recommend cleaning the burn pot and cook box – push the ash into the ash and grease drawer with the Weber scraper provided. See your owner’s manual for more details.
Ash on the outside can easily be wiped down with a soft cloth or paper towel
For other (non-Weber) fuel owners: The barbecue is designed for Weber All-Natural pellets for optimal performance.
