Get plenum-rated cable to run in heat ducts. It's more expensive, but the cost of the actual cable isn't a big part of the total. It's widely available. And you can easily identify it by looking at it -- look for where it says it's plenum-rated. -- David Dyer-Bennet, dd-b at dd-b.net / http://www.dd-b.net/dd-b/ John Dyer-Bennet 1915-2002 Memorial Site http://john.dyer-bennet.net Dragaera mailing lists, see http://dragaera.info
