in the back of the wii you will see like this grid looking thing on the back and that is the air vent

Attached to the back of the dryer.

It is done all the time, back to back bathrooms are going to use the same vent and drain line.

First, be sure to unplug your dryer, extend your dryer out, not too far though..just the length of your vent, unscrew your vent from the back of the dryer, then slowly slide the vent off. It's recommended at this point that you get some kind of vacuum cleaner, and insert it into the dryer hole. Afterwards, use your vacuum inside the vent tube, reattach the vent tube to the vent, push the dryer back to its position, and go about your day.
