All the way out -- that is, the disk-shaped weight as far as it will go from the swinging plate -- is the position that requires the highest draft to open. So, it makes sense that it would open only when the stove is cranked up. As you adjust the weight closer to the damper plate, it should open at lower drafts. You can use a manometer to set whatever draft is recommended for your stove. Or you can use trial and error over a period of days or weeks to get a workable setting. If you set too high a draft you will be wasting heat up the chimney. If you set too low a draft, the stove may be sluggish and not respond quickly when you add new coal or want more heat. My stove recommends .06 to .10 draft. It will burn at lower settings, but it is not as manageable.
