Can someone tell me if the pyramid hood comes with the stuff that you would need for the outside of your house? We are a DIY installation here and before we order my husband would like to know what he needs to hook the hood up.

It looks like you would need to buy your own duct work for the wall and going outside of the house, correct? We are venting it right out the back of the wall. Also, I see on the instructions manual it says you need to buy a 90 degree elbow to vent it out of the wall. That seems easy enough - something like that can be purchased at Home Depot or Lowes, right? I dont need to order that from BlueStar with my hood? I imagine buying it at the store yourself id probably cheaper.
