PRODUCT AND SAFETY INFORMATION DEFINITIONS INSTALLER The following terms are used throughout this manual to bring attention to the presence of potential hazards or to important information concerning the product. DANGER Indicates the presence of a hazardous situation which, if ignored, will result in substantial property damage, serious injury, or death. WARNING Read all instructions as outlined in this manual and in the boiler installation manual.
Chapter 1 - PRE-INSTALLATION REQUIREMENTS Removal of an Existing Boiler from a Common Vent System DANGER Do not install the PRESTIGE into a common vent with any other gas or oil appliances. This will cause flue gas spillage or appliance malfunction, resulting in substantial property damage, serious injury, or death. When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the remaining appliances.
CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS 1.2. Vent/Combustion Air Piping and Materials CHAPTER 1 NOTICE The installation must conform to the requirements of the authority having jurisdiction or, in the absence of such requirements, to the National Fuel Gas Code, ANSI Z223.1/ NFPA 54, and/or Natural Gas and Propane Installation Code, CAN/CSA B149.1. The Prestige is certified per ANSI Z21.13 as a Category IV (indoor air) or Direct Vent (sealed combustion) appliance.
CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS • • A specific vent adapter is required to transition from the boiler vent outlet adapter to specific stainless steel vent system. Contact the appropriate AL29-4C® vent manufacturer for transition adapter information. When using stainless steel for the vent system, PVC or CPVC pipe meeting the listed requirements in this manual may be utilized for the combustion air piping.
