I'm guessing you need to use the same specs as any indoor gas appliance. That said, here is a link to a manufacturer I used a few years back: http://www.selkirkinc.com/retail/catalog/typeb.html

I was able to find very few of their products in Home Depot, and a few more orderable via Ace Hardware, if my memory is correct.

Best of Luck to you.
