Where to buy through the wall vent for OTR microwave
I'm trying to find the venting parts (ductwork) for our OTR microwave. I want to vent it through the wall so it would be a very short piece of duct (8" maybe) plus the wall cap for the exterior. The duct opening needs to be 3.25" x 10" to fit the microwave opening. The installation instructions have a dandy little illistration of one but fails to tell you where to get it.
I have tried Lowes, Home Depot, Ace and a HVAC & plumbing supply house. Can't find it on the internet, either.
They have them at my Lowes and HD. If you go to the kitchen dept where the range hood are, many times that material is right there. Ask an associate.
You may need to transition the 3.25x10 to a round duct to find a good wall vent, but those transition pieces are everywhere. Maybe instead of going right into the wall from the OTR, you can go up into the cabinet above where you can transition to a round duct and send that right out of the wall with the vent. - http://www.lowes.com/lowes/lkn?actio...377&lpage=none
