I just started stove last night I have a couple questions. I know the unit is a bottom feed. Does the burnpot always have ash build up on side toward window I already escaped it out once. I am used to no ashes in burnpot.is the idea to push ashes out of burnpot into ashpan During constant mode does it just run nonstop on that setting. My old stove would drop to minimum once it hit temp setting. Thanks love stove so far. Just gotta get used to diffences.
