exposed to wind)
Freshly cut wood has an approximate water content of 50 to 60% depending on when it
was harvested. As the above table shows, the water content of the firewood decreases
the longer the wood is stored depending on how dry and warm the storage location is.
The ideal water content of firewood is between 15 and 25%. If the water content falls
below 15%, we recommend you adjust the combustion control to the fuel.
