I started my first fire in my Englander 30 last night. It burned very well with the door cracked open, but with the door shut (after about 10m) and the vent fully opened the fire diminshed dramatically. With the vent half way open, the fire nearly extinguished. This is my first time using a stove with a glass front so I am not sure if I am just being picky. Also, I left the vent fully opened and all the wood had burned completely (the fire just looked "weak"). Hope my description is adequate.
