Wanted to switch mv from recirc vent to venting outside

The mv was originally installed as recirc venting as there was no outside vent. I hated the steam and smoke just being put back into the kitchen.

I removed mv unit, ran a vent thru cabinets, thru attic, to outside vent. Installed new part on top on mv, installed mv and hooked up to new vent.

Works great now. Getting a good tight seal was difficult because the area the vent ran was so small.
