Grandpas Grub, MAAP flame is around 2000 degrees, whereas the felt melts at 1100. not surprised it melted!there are many instances where the adhesive is what's failing, not the gasket. but when it does melt together, i think the whiz is lately postulating (please correct me of i'm wrong) that the brief intense heat of a carbon monoxide flashover (different than a flashback) might be enough to melt the surface of two close gaskets. the entire gasket needn't burn thru, could be just the two surfaces melting together. i still think that when the lid is opened and the gasket peels away, it is a glue failure. sometimes those gaskets stick when they peel off, and again, if it peels off, i gotta think it's glue melting.
