So im splitting some Ash up to 7-9 inches thick by 16 -18 long; this stuff looks huge compared to the toothpicks i was burning last year. The question is will these splits be too big for a 2.3 cf firbox the Osburn 2000 insert offers? Im going from a 1.3 cf firebox to the 2.3 because thats as big as my fireplace will handle, just want to make sure Im not cutting too big. Thanks for all the help from you veteran wood burners out there this site rocks.
