i got an epa stove, the kind with the fenestrated bars blowing air on the fire from above. it was working reasonably well over the winter, thankfully. then i ran out of wood and had to go with another supplier whose wood was not as well seasoned. i noticed over time that my draw was getting less and less. the stove is basically unusable now since every time you open the door you are blasted by smoke that ought to be going up the chimney. something is definitely not kosher here since the fire will lose its flame and smolder away if the door is closed. is the decreased draw due to creosote from the green wood clogging up the internal oxygen supplying plumbing? i have checked my chimney and it is not obstructed. is there a way to fix this?
