And try to seal up all of the vent passages as much as possible before lifting the unit into place. Ours spit so much grease through the "sealed" passages onto the cabinets above that I had to make blank off plates and seal up all the passages on the positive side of the blower. I'm going back to 2 separate pieces as soon as possible.
