Glad your back running
I bet there was a lot of ash buildup in the holes
That should be done every 6-7 days. Also make sure you vac around and in between the heat tubes in the top of the chamber. The monthly cleaning is the same as you are doing now but in addition you need to remove the rectangular back cast iron piece. The back side of this panel will probably have a heavy thick layer of gray to black ash on it which you need to vacuum off. While that piece is off, you should vacuum the back wall of the stove because it too will get dirty.
I forgot to mention.....the entire lower metal piece where the two holes are that you vacuumed out.....that piece also lifts out....the backside of it also gets real dirty BUT it's a bit of a pain to pull out and put back in. I would keep watching all the Enviro cleaning videos...they are helpful! If you have a good friendly dealer nearby, I would go there and see if they will help you learn how to remove and replace this lower metal piece.....much easier to do on a clean floor model. Also read the owner's manual religiously. My first winter was trial and error, live and learn....nervously! Good luck, Bill
