hi everyone this is a great site here! lots of good info. i just just have a question for enviro ef3 owners/servicepeople(hearthtools?) . i cleaned my stove recently i pulled left side off where damper rod is to clean exhaust blower but might have lost my damper setting. how far out in general should the damper rod be pulled out without using a magnehelic or using flame pattern in manual? just dont want to play with it too much. i have beeen running stove with damper out about 1/2 way is this close even on hi fire.
