Should have video tapped it. Made a difference in my Englander PDV. My girlfriend was dobtful about it working on her GlowKing insert. I got a piece of 3 inch metal dryer vent and snaked it through the cleanout hole in the fireplace to the outside. The Glowking right side baffle can't be cleaned real easy. Plus they don't make these stoves any more so I try to stay away from removing them. Let me tell you, she called me this morning and said the stove is burning like it did a few years ago, nice white ash on the glass!....Great idea from whoever thought of it!
