*Ratings are based on wood that is thoroughly air dry to 15-20% moisture and weighs at least 28.75 lbs/cu.ft or good quality coal.
**Net wood or coal capacity is 80% of gross or the amount of new fuel added on an existing fire bed.
***The basic difference between the COF and WOF furnaces are the grates. Obviously, wood can be burned on the coal grate with the same rated output as the WOF22.
^Units shipped into areas where bituminous coal may be burned may have larger diameter stack.
