As you may have read I'm in full research mode here. And this place is usually great for it. Although I'm surprised at how little info I've found on the E-classic EPA OWB users input I've found on here or Hearth. What I have found isn't the greatest info thus far. A lot of tinkering yet. I'm mainly interested in the 1400 unit as after that it just gets very pricey. If you are using the E-classic 1400 I'd love to hear your thoughts and experiences. Using less wood and seeing less smoke is a concern for me. Thanks in advance for info...
