Ok guys, I've had my 5000e going since October. I really like the stove so far. Here recently though it's been puffing out some thick black smoke like I'm burning a tire! The only thing I can think of is that the fire isn't getting enough oxygen to allow for a complete burn. When I open the firebox door when the black smoke is coming out and while the blower is running, all of the gasses inside the stove ignite and the flames get bigger and the fire seems to burn much better. Once the door is closed back up though the smoke comes right back. I have emptied the ash drawer and cleaned some of the coal bed out because is was pretty thick. The next thing i was going to try is take the blower off of the stove and just verify that there isn't anything blocking the flow. I was just curious if anyone has had this issue or not. Thanks.
