i just recently purchased an Englander 25dpv. It was built in 2006. When I first got it, after "start up" cycle was complete...it wouldn't feed enough pellets to keep itself going. So I read up a bit(on this site actually) and found how to reprogram the control board. I've done that twice now(only because first time was the same result), it burns constantly, and with the same amount of flame and what seems to be the same amount of air, no matter what setting I have the heat and blower on. At this point, I set it to "C". The bottom 3 buttons are 6.4.1, but whether I have the main controls on 1.1 or 9.9, I get the same amount of heat. Which seems to me more like it would be on a setting of like 1 or 2? And I don't know if it's helpful, but the pellets, once burned, turn into kind of a crust in burn pot? Any help would be awesome. Thank you from the newbie.
