Hi all - I have an E-Classic 1400 going on my 6th season heating my home with it. It's run flawlessly during that period. I'll be leaving for Manchester, NH to see the Boston Pops Orchestra perform so i went outside to add enough firewood to hopefully hold me over until I get home around 11:00pm. When I approached it, I noticed on the LCD display it was showing a "Hi" water temp, meaning that water went over 200 degrees. CB designed the OWB to shutdown to protect itself from boiling over. I noticed that smoke was coming from the chimney and I checked to be sure I closed the by-pass door. I did. I then checked the primary solenoid and it was hung up, remaining open thus allowing air to continue feeding the fire. But, I also noticed that it wasn't laying flat on the primary elbow, I straightened it out and it dropped to cover the primary elbow opening. I put enough wood in it to get me to the point when I can check on it when I return from the concert. When I get home from the concert I'll check on it to be sure the solenoid closed. I'll know as soon as I look at the LCD display. It makes me uneasy knowing it hung up once today, I hope this isn't a sign of what the winter will be like. Wish me luck. Roger
