The higher residential appliance efficiency levels prescribed by the National Applicance Energy Conservation Act of 1987 increase the potential for condensation-related problems in gas appliance venting systems. National guidelines address the venting of modern gas appliances into interior chimneys and vents. The performance of exterior chimneys, however, depends largely on the local climate. The objective of the report is to provide a technical basis for developing guidelines for avoiding excessive condensation when venting gas appliances into exterior masonry chimneys. The VENT-II computer program was used to evaluate the performance of exterior chimneys under a wide range of conditions, including application type, appliance efficiency, appliance operating characteristics, and chimney size. To account for variations in local climatic conditions, the DOE heating regions for the U.S. were used in the analysis.
