Old Yankee by Lopi problem

[TKRussell]

I have a lot of experience burning wood. I'm getting older and took someone up on an offer for a free pellet stove. Yankee by Lopi.

I cleaned it out. Everything is clean. Changed the door gasket. Its a new vent. Duravent straight out the wall then up 5 feet outside.

-It rips through pellets faster than the auger spits them out. No matter what the "Heat" dial is set at
-The damper on the right (its a slide -pull in and out- mechanism) makes a small difference in the behavior of the flame. Not stopping my problem
-There's an exhaust damper on the left side of the unit that can be operated with a socket
-There is a gauge that tells how far the damper is open / closed. Its a horizontal slit in the sheet metal with a little metal tab sticking through it
-That metal tab is all the way towards the outside wall of the stove. As far as I can tell (from looking at literature I've found online) that means the exhaust damper is wide open?
-Should I mess around with the exhaust damper?
-Should I be looking at anything else?

Thank you. Hoping to be able to figure this out.

Edit: Sooo... I didn't notice there is a reducer going from the 4 inch exhaust flange to a 3 inch. The manual calls for 4 inch. The old user was using a 3 inch vent system it would seem. Would explain why the exhaust damper is wide open. I installed a 3 inch vent to match what was coming out of the stove. Looks like I'm installing 4 inch
