I have a Mt Vernon AE insert which has a smaller hopper capacity that the freestanding and I am finding that all of the pellets do not funnel down very well. I can load the hopper and throughout the night I find that the unit runs out of pellets however there is still a good bit of pellets left when I open the lid, they are just not funneled down. I was wondering if anyone has a solution for this. I was thinking of cleaning the hopper area well and maybe polishing/ waxing the hopper in the area where they hang up. Any thought??
