Oct 18, 2015 · PROPER ASH REMOVAL. Whenever you burn a solid fuel, such as wood, coal, or pellets, in your stove, fireplace, or insert, you will be left with ashes to remove. These ashes must be removed periodically as they can affect both performance and durability of the product. The frequency of this ash removal will depend on the product itself, the type of fuel being burned, and the species of the fuel (e.g. …
