3+ weeks burning and loving the econoburn. Still looking forward to modification of fan issue but great none the same. Oil boiler hasn't kicked on unless I made it come on just to cycle oil through the nozzle. Does any econo users have any tips on how to prevent smoke from rolling out the firebox door when adding wood? I've opened the damper for a minute and more like the manual suggests, I've tried opening the secondary door to get a good flame and draft going prior to opening the fire box but I still get smoke out the firebox door. Anybody have any tips?
