Chapter 1 - PRE-INSTALLATION REQUIREMENTS Ventilation and Combustion Air Requirements The INSTINCT boiler is classified as a Category IV appliance. This utilizes uncontaminated indoor or outdoor air for appliance combustion. A direct vent installation uses the outdoor air. Air supply, combustion chamber, heat exchanger and evacuation of POC (products of combustion) for this type of appliance is sealed with respect to the room in which the appliance is installed.
CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS 1.2. CHAPTER 1 Removal of an Existing Boiler from a Common Vent System DANGER Do not install the INSTINCT 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 • • • PVC Schedule 40 - ANSI/ASTM D1785 PVC-DWV - ANSI/ASTM D2665 CPVC Schedule 40 - ANSI/ASTM F441 Approved AL29-4C® Stainless Steel vent manufacturers and vent systems: 1.3.2 PVC and CPVC Pipe Cement and Primer • • 1.3.3 AL29-4C® Stainless Steel Vent Piping and Fittings CHAPTER 1 1.3.1 PVC and CPVC Vent and Combustion Air Piping and Fittings PVC - ANSI/ASTM D2564 CPVC - ANSI/ASTM F493 • SelKirk/Heatfab • DuraVent • Z-FLEX U.S. Inc.
CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS 1.4. CHAPTER 1 • • Vent/Combustion Lengths Air Equivalent For all venting applications, PVC/CPVC or AL294C® Stainless Steel the length must not exceed the lengths listed in Table 2 below. For PVC/CPVC or AL29-4C® vent systems, reduce the maximum allowable length for each elbow as follows: • • 1.5. 3 feet for every 45º elbow 5 feet for every 90º elbow Vent Restrictions 1.5.
CHAPTER 1 - PRE-INSTALLATION REQUIREMENTS Combustion Air Contamination WARNING If the INSTINCT combustion air inlet is located in an area likely to cause or contain contamination, or if products which could contaminate the air cannot be removed, the combustion air must be repiped and terminated at another location. Contaminated combustion air will damage the unit and its burner system, and can result in substantial property damage, serious injury, or death.
