When I fired up my E-classic 1400 a couple of weeks ago I did it per instructions in the manual. I think it took 3 hours for the water to get to 185 (My high set point). This is my second season with it. Lovin it so far. However, this morning (at 5:00am) I did a thorough cleaning of the fire box. mainly to see what the air holes are doing, and cleaned the reaction chamber. When I re-fired it (I saved the hot coals in a metal bucket to aid in re-firing). I then added kindling and moderately sized wood and purposely left the reaction chamber door open to help it kindle quicker. Inside of 10 minutes my water temp went from 175 to 185 (My low set point for the fall at 177. When it gets to be winter I'll probably turn off the pulse). I closed the reaction chamber door, added more wood to last the next 24 hours, shut the fire box door and reaction chamber bypass door. The thing is running like a charm. Roger
