Just installed my new drolet escape 1800i. I made a fire to break it in and get rid of the paint smell. Opened a couple of windows in the living room. At 9:30pm I had a nice coalbed and decided to test the burn times. Loaded it full of dry oak and it was throwing excellent heat. I watched the secondaries for a while after slowly tapering it down until control was almost all the way in. Just checked at 1:30AM and it was still throwing heat, stove temp around 300-350 degrees and a ton of coals. From what I've read about the stove I was expecting 8-10 burn times, until around at least 6am. Could the window being open affect the burn time or is this normal to have coals after 4 hours and still put off heat for another 4 hours? Thanks
