I got a call today from Englander about the SmartStove 55-SHSSP01, and a potential issue where smoke builds up in the chamber, and the stove fails to light, yet still under the safely ignition timeout, then suddenly it ignites with a bang. They are sending me a new burn pot and igniter. Although I personally have not had any issues yet, I've only had it for a few months, and due to a mild winter here, have not even put a ton of pellets through it. The slight smoke before the fire on mine clears quickly, as the exhaust fan is running during that time. Anyway, just a heads up to anyone who has this stove, and have not yet registered with Englander yet (Its a new model). Might want to get in touch with them.
