Off the top of my head, this is probably allowed. You can terminate exposed on a patio or deck where people walk and could touch it. Most mfrs. make heat shields or cages, which do help. As long as that breezeway maintains a breeze, you're probably ok. For instance, most mfrs. allow you to vent onto a porch as long as its not screened in.

David has given you the best advice--locate the mfrs. listed instructions and go by the chart therein. If you record the model and serial number, you can contact the mfr's technical services for assistance. They can either send you a manual or tell you over the phone. If you go with the verbal response, but sure to note the tech rep's name, date, and time you spoke.
