** the hood outside is a standard 6" one like those used for dryers. **

Dryers use 4" vent pipe with a 4" vent cover.

** Where can I get a proper draft door for this? **

You can get a Jenn Air spring loaded 6" wall cap at the following link:

** is there a damper I can install that can close it off totally when not in use? **

I'm sure it should be possible to install a manual damper into the ducting (if you still have access to it) like is often used in heating ductwork but anything you install in such a line will contribute to a grease build up there and also hamper cleaning of the ducting when necessary.

I saw the link for a Jenn-Air vent cover assembly that you posted for a 6 inch opening. Do you know where I can find a 5 inch one? My Jenn-Air cooktop is vented with a 5 inch tube. Many thanks!
