My son and I carried the stove (Century Hearth FW300010) outside and built a fire in it. With the door open I could keep the fire going but every time I closed the door it would just smolder. Damper is fully open. Temp only at 200 degrees. Out side air temp is currently 50 degrees, plus the glass is nearly blackened out. I thought the wood may be damp because I could here it fizzing when I had the door open. My son went and picked up seasoned, dry oak. We started over again. Same thing is happening all over again. Could all this be because there's no stove pipe connected on top or is this normal? I thought I would be able to watch the logs burn not smolder. Be fore I sent this I checked it again. Stove temp 200 degrees, glass nearly darkened out. I opened the door and on fire, just smoldering again. Damper is fully open. Please send advice, Thanks
