I just purchased a used 602N enamel wood buring stove that appears to have all the parts and is in good conditon. Paid only $60. I am trying to figure how to install the burnplates . The two side plates are rectangular with one corner cut off and then 3 holes for hanging. Then there is the curved top plate. Can't really figure out how they are to be installed correctly. Is there supposed to be a plate for the bottom of the stove? Any help would be appreciated.
