Maxim M250/255 P Inspection Window Gasket Replacement

Description

This product refers to the gasket used with the Inspection Window assemblies on Maxim M250/M255 P models . The size of the required window depends on the furnace’s serial number; earlier models (s/n M2000002 to M2000063) use a 2 ′′ x 2 ′′ window (p/n 9254) , while later models (s/n M2000064 and higher) require a 2 ′′ x 3 ′′ window (p/n 9527) . The gasket is essential for sealing the window and maintaining an airtight burn chamber .
