Purchased a new Mt Vernon AE

I think your suspecion is warranted. On my harman I would get massive clinkers around the shoulder heating season and a stove nearly clean enough to eat off in the middle of February.

There is no way that the stove can not keep up unless you have it in a warehouse and burning sand.

You'll find that the mt Vernon is a real pellet miser. The auto mode is part of the reason for this. By keeping the temp below the set point, the stove runs longer and therefore more efficiently. Every time a stove shuts down, it must restart and heat back up which uses more pellets per btu of heat produced. You could equate to a smooth power transition in a car vs "jack rabbiting".If you want to have the temp warmer, just set the set point higher. It is designed to idle a couple of degrees below the set point. Nice install btw.

HAhaha...Burning sand (Hmmm, maybe that's what they make Green Supreme's out of)!!
