Summary of Topics

This is the first issue of the Outline of Investigation for Venting Systems for Use with Gas-Fired Direct Vent Appliances, Subject 2112. These requirements cover these types of direct vent venting systems that are not directly dependent on the intended end-use application. This would reduce the amount of duplicate testing (testing done on both the appliance and the venting system).
