We just purchased a small Englander for our kennel and are super pleased with its efficiency. It runs great! However, it never auto-started, even the first time. It's as if the little ignitor hole never really comes up to full heat to light the pellets. After waiting 30-min and then going to check, it has the E-2 error (failure to start) message, so we just start it manually. Any thoughts on this failure?
