Part Description: These are genuine replacement air tubes that are found in the Hearthstone Heritage 8024 wood stove. Secondary air tubes in a wood stove are essential for high-efficiency, cleaner burning by re-igniting smoke and gases before they exit the chimney. Located at the top of the firebox, these tubes inject heated oxygen into the smoke, creating a “secondary combustion” that increases heat output, reduces creosote buildup, and ensures a more complete burn.
