This is a wood burning stove insert that works, is in near new condition as it has been used a few times. The measurements for the fireplace are 26 1/2 x 18 3/4. It will need a boot connector and that measures 16 x 4 1/2. The frame for it measures 42 x 32. It does have built in blower and fan does work. Any questions please respond. Am willing to negotiate.
