I know I started this topic a couple of weeks ago. Since I just fired up my stove this weekend I wanted to post my results. I know many people suggested that I adjust my feed rate until the flames reach 4 inches which I did over the course of the day. Unfortunately on my Santa Fe I was only able to accomplish this height only when the feed rate was fully opened. In addition the 4 inch height is very intermittent. Very disappointed about the feed rate being fully opened as I have read many posts about their feed rate at the smallest setting. I am using Hamers Hot Ones and they are by far the shortest pellet I have ever used. I always feel that the burn pot doesn't have enough pellets in it. Any thoughts? Like I said the stove is relatively brand new.
