So I failed the dollar bill test and I am looking for new rope gasket. The owners manual refers to part number 50-2058 for Door and Ash Door. 9/16 Firm. Not sure what 9/16 firm means because I can't find any rope gasket of that thickness. Measuring the width of the gasket already on the door gives me 7/16, but I am not sure that is correct being it is compressed and still on the door. And I don't want to take it out without having the replacement. Only place that I found that has the part is the below link http://www.stove-parts-unlimited.com/Enviro_Pellet_Door_and_Ash_Door_Gasket_p/50-2058.htm It seems expensive when all other gaskets cost about $10. Plus it would be nice to have a local source, if I just knew the specs. May be I will bug Enviro. Any ideas would be appreciated.
