Hey Folks, new to this forum. I purchased an older, two door F400 castine, it had never been used. As a life long Vermont Castings owner I am excited about burning this quality stove as well. Here seems to be my problem. I have been using the stove for a week now, and it is doing a terrific job of heating my home, but the air control lever doesn't seem to impact my fire, left or right. With the Vermont castings, I've had both the Vigilent and the resolute, I was virtually able to immediately calm my fire by reducing the air intake. Here, I cannot even tell the diference. Perhaps the levor is broken. Is this a common problem. Incidentally, I placed a magazine over the hole in the back and was able to manually cut of the air, and watch the flame drop drastically. Any help? Thanks
