Wow...just had the same issue. I am leaving here shortly to head up to the store about this. I also ordered the vent...it came without a motor! This Viking appliance package has been a nightmare! PLUS the salesman never asked me if I wanted my gas stove set up for natural or LP gas! So of coarse the wrong one was ordered! ALSO, I ordered the hook up kits for the washer and dryer and they never delivered the two kits. I am not happy with Best Buy right now.
