so i got my hampton hi200 installed and have it going for the first time tonight....this is my first insert/stove althougth i have been around them a little bit....so i had a little fire for awhile, let it warm up and add a little more....with the door cracked just a bit or open it burns with nice flames and all smoke goes up the flue....but when i close the door with the draft full open pretty much all of the flames disappear although the cools glow a little bit with the occasional weak flame......i assume you are supposed to have active vigorous flames with the door closed and the draft full open....when i move the draft control it makes some sliding sounds like it is doing something but it seems to me it is a little short on oxygen with the door closed....am i supposed to position the wood a certain way? does the brick and flue have to "break in"? i have had it going for a couple hours and i don't feel much heat either....help!
