Michigan wood fuel High temp, side of door. 361 Air temp - 174.4 Fines - medium Ash volume - 14oz Ash weight - 3.86oz Ash percent - .60% Bag weight -40lbs Stove setting - medium Fuel type - Hardwood Pellet length - 3/8” - 1 3/8” $209 ton A few of the pellets where longer ,but not to bad. Heat was on the lower side. There was a good amount of ash that was, some what fluffy and gray in color. The hard ash left in the burn pot did fall apart and crumble pretty easy. These might be 2.5 stars but with the ash percentage and lower heat I don't feel it should be 3 stars. This is a home test, always try a few bags for yourself before stocking up.
