Kelly, I too have been told of this new revision to NFPA-54 Chapter 10 (10.8.3)

It has been in effect since the end of July, I've been told.

It pertains to direct vent appliances, mechanical-vent heating appliances or domestic hot water equipment , where the bottom of the vent terminal is installed below four feet above grade.

Also there is Nicole's Law under the making which will require a CO detector in all public housing units by Jan 1st 2007.

In memory of Nicole Garofalo, who died in her Plymouth home this past winter when a snow drift blocked the vent for the furnace...
