Planning install of a Blaze King princess 29 insert, manual states 6 inch liner "recommended"
Chimney inspection failed due to gaps between clay flue tiles, but no creasote observed. Inspection report indicates a 26' length and cross section of 9x13, consistent with my measuring about 7.5" ID. See pic.
I know that will be a tight fit after insulating the 6 inch liner. Too tight? My local dealer insists on clay flue removal. Am I irrational and naive to prefer keeping it? It's already there, why not try to keep one extra layer of insulation/protection/vertical support? Is sweeping a factory ovalized liner that much more of a pain?
My preference would be 0.010 single wall 304, light-heavyweight/crossover/hybrid, factory ovalized if needed. Between the smooth wall and height I'm not worried about the minor decrease in cross section with ovalized (tell me if I should be).
Dealer also doesn't seem very keen to move away from their standard 0.060 corrugated liner.
Thanks!
