Back to Basics: Venting for Gas-Fired Boilers | 2003-06-04

Jun 04, 2003· The venting section of the instructions should offer clear guidelines for proper vent system installation. These requirements are also noted on the boiler's rating plate, which is affixed to each unit. The rating plate contains basic information about the boiler, such as the manufacturer, model number, input and the vent category.
