Summers Heat 49cpm- Is this normal?

A few questions from a newbie. This is my first stove, so I'm not real sure if this normal. My first and second burn on the stove, I noticed the flame will get pretty low at times. I have the stove set at 50%, or 5, and it doesn't seem to stay at the same level. The flame gets big then very low, then big.
I also noticed the pellets are more prone to fall on the left side of the burn pot, causing the flame to be more on that side. The pellets build up on the right, then catch
fire and the process starts all over again. Is it me or should the whole burn pot be fired off? Should the flame stay about the same size for a certain setting?

thanks for your help.

The stove is new, so the build up of dust is unlikely. The pellets fall from the auger and strike a divider in the burn pot. I think the divider is a little offset, but the fact
that the left side burns more than the right might be from the blower unit not spreading, or blowing, evenly under the pot. What do you guys think?

Thanks Mike. The divider is little off center as you described. I guess my impression is the flame should stay at, or near, a 50 percent level with the setting on 5.
It's seems odd to me the flame would drop, almost to the level off the burn pot upper lip, on a medium setting. Don't get me wrong, I think this stove is great but I just needed to know this was normal
