I have acquired an ancient Whitfield legend to heat my small wood shop. I have replaced 2 of the motors, one of which was the combustion fan motor. I am still not getting the best burn I could. The stove came with a clearly thrown-together/fabricated burn pot liner. Being home made I don't believe my pellets are getting an ample amount of oxygen and want to replace the liner. I have searched and searched for an image of an original but have been unsuccessful. Can anyone out there provide a photo of an original liner that came with the Legend? Or does anyone have a suggestion for superior designs I could modify for the specific stove? Thanks in advance.
