to many posts making this seem harder than it is. Split some, test it, burn the driest first. If the driest isn't dry enough by the forum's standards then you burn it anyway, because it's what you have. Wet wood will burn, you just have to know the major downfalls of doing it. Recognize that you will lose efficiency and create more creosote (and potentially a fire risk), so you will need to be vigilant about cleaning and checking your chimney through the winter.
