I cut a slot out of the front of the half pan a little larger than the AMNPS
Folded an aluminum disposable grill topper to allow a little more air under the AMNPS
Cut a hole in the lid and sealed in a small piece of aluminum flex duct with RTV sealant. Then sealed the lid to the pan with RTV sealant. These lids are rated to 220°, I don't think the AMNPS will produce that much heat.
I added some aluminum tape to the edges to ensure a good seal and cover up that bright red RTV sealant and connected it to the 3" elbow on my MES 30, already there from the mailbox mod.
Of course I had to test it out. Lit the AMNPS and placed it in the half pan and foiled taped some of the slot to restrict airflow.
Works like a champ
And sits nicely, right next to my MES 30
Thanks for looking everyone.
