I posted here a couple weeks ago about my new Englander 30-NC installed in a walkout basement. The fire died out when the door was closed, but roared if the door was open just a crack. Got a lot of good advice and made some changes, with some improvement, but still doesn't seem right. The stove sits on a nine inch pedestal in the basement area, with a two foot vertical run, then 2 45 degree elbows going to horizontal, then a two foot horizontal run, then a 90 degree elbow going upward. It's about 23 feet from there to the top of the chimney. Fire starts fine, and roars away, as long as the door is cracked open just a hair. The stove air inlet is fully open. Temps on the stove range from 450-520, and temp at the pipe entrance to the wall is between 250-300. The fan is off. Now, if I seal the door, the fire continues, but gradually fades to wispy blue flames. The red coals at the bottom keep burning bright red. The temps though drop on the stove to about 350, and the pipe at the wall drops to 225. I've never used a woodstove before, but to me that doesn't sound right. The temps are too low to keep creosote from forming in the liner, correct? Lots of past advice centered on the flue draft perhaps being too low, but I still don't understand why cracking the stove door open just a bit would change the flue draft and make a difference. And I don't see why the flue draft should be a problem. The install essentially mimics the install shown in the manual. Thanks for any any advice.
