please remember this very important information....
Cell density (16 or 25 cpsi) plus the combustor dimensions are both very important to the stove’s operation. The combustor's size and cell density was designed into the stove by the stove's manufacturer for best performance.
1. Open frontal area of the combustor is designed to receive the flow rate of the gases coming from the firebox.
2. The combustor’s size and cell density will control the residence time needed for the gases to burn within the combustor.
Always replace the stove’s combustor, when needed, with the original OEM combustor size and cell density for best efficiency and performance of the stove.
