seeing as the weather is so warm today I decided to clean out my PE Vista stove...I tried to remove the baffle as per the instruction manual but can't seem to figure out how the rail extensions come out...the rail extensions have tabs that fit through a slot on the brick rails below...but the tabs on the rail extensions appear to have been bent/twisted so that they can no longer be disconnected from the brick rail...any ideas? also...when I lifted the baffle a 1 inch piece of the baffle gasket fell out...should the gasket be replaced?...it is the original gasket for the stove which was installed in Nov. 05...I hope I explained this well enough....
