I'm a newbie and need your help. We have a new LOPI Endeavor in the living room with double wall pipe, which was professionally installed, and use it to heat the whole place, 1850 sq ft. We love the glass door and the idea of cutting, splitting, stacking, and burning our own wood. And it sure does put out the heat. However, we've noticed something this far into the heating season that's bothering us. We seem to have a lot of dust. When we wipe down a glass top table in the living room with a damp wipe, the wipe comes up with lots of black sooty looking stuff on it. It's scary. Naturally we're wondering if this could affect our health. I do open up both air controls before I open the door to add wood, and it always appears to be pulling air in as I load it. I'm also very careful when I empty the ashes, about once a week. What else should I be doing.....or not doing?
