I've had my AMNPS for a year and a half ... love it ... most of the time ... but lately it seems like the AMNPS goes out more often than not in my mailbox mod.
I'm using Todd's pellets (Pitmaster's Choice), microwave 'em 'til they're really hot ... light 'em with a torch, let 'em burn for 10-15 minutes and put 'em in the mailbox.
As the pictures show that I have 3 "port holes" in the door of the mailbox ... and a 3" duct out the back into the Brinkman. I've tried opening and/or closing different configurations of "baffles" on the Brinkman ... and nothing seems to make much difference.
At times it almost seems like I'm getting a backdraft through the Brinkman that pushes the smoke back into the mailbox ... not desired, either.
So ... how 'bout some help ...
- How can I keep the pellets lit?
- How can I keep the smoke from back-drafting?
