Love this site and have been surfing threads here and now have some questions. Purchased a 25-ep for my upstairs and have a breckwell downstairs and both are running ligentics pellets. Troubles are the englander builds up fly ash 5-6 times faster than the breckwell. It seems I have a control panel issue as the thermostat I wired in would not work and was told by the factory to change the setting and the panel would not let me change as instructed. While on the phone with the factory I was told to check the lower panel setting and changed the setting to 1-4-1 and then found the stove would not run (stay lit) on anything less the a 5 setting. after talking with them again I was told to set the lower keys to 2-4-1. first question is what are these settings for and what is everyone else running theirs at. Also they are sending me a new control panel and was wondering if you think this will correct the high fly ash build-up, not staying lit on anything below 5, and the thermostat problem. Sorry for so many questions and thank you for your responces...G
