After buying 3 ton of VT wood pellets, I decided to try a few bags of okies. I noticed that with the okies, my glass wasn't getting nearly as dirty as with the VTWP. I have always left the feed rate knob at 3.5, even though the manual suggests leaving it at 4. After doing some research, it seemed that my stove might be running a little rich. So I decided to turn the knob down to 2.75. Success! At 3.5 1/3 of the glass would be dark brown within 1/2 day. Now, at 2.75, there is very light graying in the same amount of time. At first I thought I would have to switch to okanagan, but with a little tweaking, I am very happy that I can continue to buy local. I was wondering what everyone else uses for a feed rate setting, with your respective pellets? Since all pellets are different. They should theoretically require different settings. I thought this might help some of the newbies out there, who might be frustrated with the performance of their stove.
