I have a LL top vent. After I recieved my stove I realized I could have gotten a top 8" duct added. I think That would have really helped me move my heat better. At these low fire time of the year I also have that situation where the air FEELS cool most of the time the blower is blowing. I just wish there was a way to get more heat off the stove through the blower. The left side of the top feels good and warm while the left is cool. I wish I could get in there and make a maze for the air to follow a longer path.Any body have any ideas how to get all the heat out of the top and back area. Other wise it really is a perfect automatic stove. Its great how it can idle along all day on a 60 day and not use much coal.
