Well I finally got my neighbor to start burning. Doring the summer he had a mason come install a chimney on the side of the house. He bought the 4100 and had no idea how to install it. He had some freinds over to install a 6" single wall liner that wouldn't pass the fire box. I went to visit him the other weekend to see how things were going.( Not good). So I talked him out of the single wall pipe and convinced him to use a flex liner. Long story short the stove is now hooked up with out much damage to the back of his new fire place. So heres the deal Chimney is 17'( tall when I put the cap on it felt like a good draft) We did are first fire on the stove on Sunday.. It didnt go well. The stove seems to be starving for air. So on Monday at work I went to hearth.com like I do every other day to see what the boys are talking about.( great stuff ) and to see if I couldn't find some info on my own. I checked the blanket I toke off the outside intake plate for more air ( does this stove have to have outside Air?) Refired the stove and it seemed to be working fine for 20min then it started to starve for air. open door and it lit right off. shut the door and same thing. It allso seem that the right side woun't burn its just charing and wont burn like the left side. I'm stumped When lighting the stove I pulled the ACC control and lifted the burn control to the high setting Guys Im at a loss any Ideas why its starving for air? Before you even think about saying it. The wood I started the fire with came from my house and yes its seasoned.
