Hello I am working on this Whitfield Advantage Plus. Originally I thought it was the Advantage III The large ash pan does not slide out because it hits the ash dump tabs. The right one more than the left on but especially the center ash dump tabs for the ash dump under the burn pot! Nothing obviously wrong is standing out here? Does anyone know how to fix this? See pics 1 - Stove 2 - Ash Pan hits tabs on center ash dump 3 - Stove with ash pan removed - Had to pry it with a screw driver to get it out! 4 - ash dump under burn pot Note: Ash dump under the burn pot does not close all the way like the left and right side dumps do. Therefore the ash pan must be behind these tabs to close all the way!
