Harman Accentra cast iron medallion with decorative compass for the Harman Accentra Insert and Accentra 52i.
This part is considered sacrificial and does need to be replaced about every 5-8 years. Signs of wear are discoloring metal (mahogany color), warping, or cracking. Always change the flame guide if you are changing the medallion as they are codependent for a proper fit.
