Well I've been burning the biomass for a week or so now and thought I would share my experiance with it. At first I was burning at factory settings and it worked pretty good. I had a loose conection on my controller and it shut off a couple of times in mid burn. I had to take the cover off and move it around to get it to come on. Got that fixed now! I raised the temp the cirrculater comes on at from 145 to 165 and it made a world of difference. before I did that I was getting a mostly yellow orange flame, now lots of blue and glowing refractory. I've found the addvise to split to the size of a card to be good. At first I was trying to get away with a few larger splits, like 2 cards and It didn't burn as well and had more bridging. At first I was wondering If I made a good decision to get a gasser, but now I'm pretty sure I made a wise decision. Thank you eveyone on Hearth for all the help along the way. J.T.
