I would like to keep my heat control at 4 and blower on 6, looking at closing throat in hopper down just a little to slow my feed rate. I am trying to keep #s at a higher rate for both blowers to operate at a higher rate without feeding pellets as fast. My adjuster plate (stock) was completey open and I closed it by an 1/8th of an inch. I was still running stove and did not get an accurate measurement but guessing it is open now about 1 1/4 - 1 1/2 now. On settings 4/6 I have been getting around 14hrs to a bag and a pile of coals after 12hr burn. After making adjustments and filling hopper i will see tonight! Anyone have any reccomended opening measurements?
