Hello there. I purchased a used CB 1200i pellet stove this year, and am refurbishing it a bit before I set it into its final home. After getting the body painted this week, I went to clean the door glass thoroughly. However I noticed that the glass was not only dirty on the inside as expected, but there outside of the glass near the top had a thich coating of ash as well. Then I looked into it further and there is no gasket sealing the glass to the door along the top - Only the other 3 sides. It's essentially one big air gap. My question is, is this normal? The manual does refer to an airwash, and lists instructions on how to change the glass, but never mention a glass gasket anywhere at all. Here are some pics but it's kinda hard to see.
