Have an EF3 as well, bought it last September and it works great. I run it 75% of the time with the dial a fire in the 9:00 position and have never had an issue with it going out. I have an Enviro MAX down stairs which has no issues on low going out but the burn pot over flows at times causing smoke in the house (Enviro is working with me on this)
I am using Eastern Ember pellets as well; they seem to be the only ones I kind find in this
