I purchased the stove in 1998 and the manual that came with it (dated 1997 version 13) list the part number as FKGRK1 but I cannot find specs on it. I read somewhere that older Onyx used 3/4" rope but only see 5/8" rope cross-referenced. In an older thread that is now locked ( https://www.hearth.com/talk/threads/yet-another-door-gasket-thread.102587/ ), I mentioned that the original lasted 1 years but the 5/8" Rutland was loo narrow. In that thread I said I will try Imperial 3/4"but I did not as I stopped burning wood at the time. Anyway the same question still stands. I am looking at this product:
GA0196 3/4" - 7' Fiberglass Gasket Rope Kit - BLACK Bag ea. ea. Cut 6 063467856825
