Well everything is working quite well! My parents are quite pleased with the whole setup and I am quite pleased that they went from never wanting anything to do with a "coal stove" to there current status.
A huge thank you to Rob R. for answering tons of questions at lighting speed via e-mail from day one to the finial setup. Steve and Ann Marie were super nice and made sure that we were pleased with our unit. I currently am feeding the high boy buck from UAE and rice from Sherman. I can not wait to be rid of the buckwheat coal, as the unit just seems to run so much better on rice. I would have to say that with the buck it does seem to burn less coal but the auger just seems to grind away with the size difference. As far as what our "regular" coal will be I am leaning toward Sherman rice or a 50/50 mix of Sherman rice and UAE rice. I like the heat and less ash that UAE puts out but the Sherman appeared to be much cleaner and is quite a bit easier to get too. I am also a little worried that in the summer time the UAE might put off too much heat when it is just not needed. Thanks again guys and I am very much looking forward to tweaking Mom and Dad's current 520 and installing a new one (new to us anyway) in our (wife and I) place this July.
