My Elm has the 2 pane system, ceramic with the plate over it, and the glass stays surprisingly clean considering its doesn't have any airwash system. I get a slight brownish haze at the end of a burn cycle that can be burned of in the next round.Diabel said:I wonder why vc decided to go with single pane glass. My old/sold (relatively new vc nc) had single pane glass and if I closed air too fast, glass would darken. My new (very old vc cat) has double pane and it has not once darken when closing air too fast.... I like the two pane system much better!
A good airwash like the Englander or US Stove has completely solves the dirty glass issue.
