AMNPS with galvanized smoke stack

[hinds90]

I'm doing the mail box mod to my electric smoker and the only elbow I could find to connect the smoker to the mail box is a galvanized steel. Will this be a issue? The smoker nor the amnps should reach temps high enough?

Ive used one for yrs. I've placed my hand on it and it was barely warm.

I believe the consensus is that unless the galvanized metal is directly exposed to high heat that the risk is minimal.

X2.  That mailbox mod would never see high enough heat to matter.  If you look at random photos of ducting used for that mod in a search, you will find that probably 95% use galvanized ducting.

As to the heat level. I did a proof of concept test one time with a cardboard box for my "mailbox" and white PVC for the ducting.  I did put a piece of sheet metal (galvanized no less) under my pellet tray so no smoldering ash would ignite the cardboard "mailbox" and there were no problems.  No where near enough heat.
