Preparing for the Shutdown and think this year after 4 winters that I would replace a couple of the Gaskets on my Accentra Insert. The Door Gasket has signs of Fraying . Also thought maybe the Hopper Gasket. I have seen Mountain View Products suggested before, but they only have the door Gasket. Anyone used other places(other than the Dealer). I wonder if the Hopper Gasket has an alternative. I thought I saw a thread before about that one , but cant seem to find it again. Any Thoughts welcome.
