The old felt gasket in particular was a gravy train for BGE seeing they had to be replaced so frequently! Ever price them? BTW I have had my Canadian customers tell me they were paying $30 for those crappy felt gaskets up there! While the Nomex gaskets last longer they still have a short life. The thing is the BGE is not capable of getting up to 2,200 degrees at the gasket level to damage the Rutland.
