Analysis of Combustion Air Openings to the Outdoors: Preliminary Results. TopicalReport, October 1992-June 1994

摘要

This report examines the technical and historical bases for existing combustionair requirements in the U.S. in cases where combustion air is obtained entirely from the outdoors and recommends sizing guidelines for combustion air openings to the outdoors based on current appliance designs and construction practices. Potential benefits of reducing the size and number of combustion air openings to the outdoors include reduced heat losses from the appliance, ductwork and vent pipe, decreased condensation and corrosion in the vent system, and lower incidence of water pipe freeze-up in appliance rooms.
