How have the mods been regarding the
AMNPS and gassers?
I just now stumbled across this link.
I have had the same issue with the
AMNPS staying lit, and I was attributing it to lack of oxygen as well.
I Home Depot(ed) and came up with this dryer vent connector set (DryerDock Vent Hose Quick Connect) for $7, and some duct $12. Then went to the dollar store and bought one red bowl $1. (Caution, the
AMNPS may flare up with a little extra wind, and boy those cheap plastic bowls melt in a hurry.)
To attach it to the smoker, I put some self-stick magnets on the white flange thing, and just popped it over the side vent. Perfect fit.
So after the fire, and cleaning all the plastic out of the
AMNPS, I traveled back to the dollar store and went with the tin pan/duct tape apparatus instead, to the capture smoke. This time I left the sides attached so that I could use for dampers, which was a great idea. Had to put a brick under the AMNPS to keep good air flow, and to keep from burning my pesky ants roaming freely in the grass.
Thin blue smoke resulted just fine, for 10 hours = happy.
Not a permanent attached modification because I like to move the smoker around (it has wheels) the yard based on which neighbor could use the smoke and smells.
