Do not attempt to vent the boiler using either CPVC/PVC without the use of the appropriate vent kit called for in this manual. • Do not apply thermal insulation to vent pipe or fittings. • Do not interchange vent systems or materials unless otherwise specified. • Do not obtain combustion air from within the building. • Do not install a barometric damper, vent damper, or drafthood on this boiler. • Unless otherwise noted, the use of CPVC is required where the vent pipe passes through enclosed spaces and through wall penetrations. • Do not use cellular core PVC (ASTM F891). • Pitch the vent piping as called for in these instructions to prevent condensate from pooling in the venting. • Starting at the boiler, the first 30” of straight pipe, and the first 90 degree elbow, in the vent system must be CPVC. PVC may only be used in the vent system downstream of this CPVC piping. CAUTION Moisture and ice may form on the surfaces around the vent termination. To prevent deterioration, surfaces should be in good repair (sealed, painted, etc.). A. Vent System Design There are several different ways to vent BWC series boilers. This installation supplement covers installation of those vent systems that employ CPVC and PVC plastic pipe. Refer to the BWC installation manual when installing avent system using stainless steel or concentric PPs venting. When CPVC/PVC pipe is used, there are two basic ways to vent a BWC boiler, each having several variations: • Horizontal (“Side Wall”) Twin Pipe Venting (Table 1.1) - Vent system exits the building through an outside wall. Combustion air and flue gas are routed between the boiler and the terminal using separate pipes. • Vertical Twin Pipe Venting (Table 1.12) - Vent system exits the building through a roof. Combustion air and flue gas are routed between the boiler and the terminal using separate pipes. All of these systems are considered “direct vent” because in all of them air for combustion is drawn directly fromthe outdoors into the boiler. A description of all of these venting options are shown in Tables 1.1 and 1.12. One of the vent option columns in Tables 1.1 or 1.12 must match the planned vent and air intake system exactly. In addition, observe the following guidelines: 1.CPVC/PVC Adaptor Kits - The use of CPVC/PVC venting on BWC boilers requires the use of a special kit. Each kit consists of the following principle components: • Adaptor/s for the Vent and Intake Connections • 30” Section of Straight CPVC Pipe • CPVC Elbow • (2) PVC Termination Tees • (2) Rodent Screens • (1 ea.) Can PVC/CPVC Primer and Cement Part Numbers for each kit are shown in Table 1.5 NOTE: Models BWC070, 090, 120 and 151 may be ordered from the factory with the above components packaged in the boiler. When this is done the vent adaptor may be shipped installed on the boiler. 2 TABLE 1.1: SUMMARY OF HORIZONTAL VENTING OPTIONS VENT OPTION # 1 2 3 4 CLASSIFICATION USED IN THIS MANUAL HORIZONTAL TWIN PIPE HORIZONTAL TWIN PIPE HORIZONTAL TWIN PIPE HORIZONTAL TWIN PIPE ILLUSTRATED IN FIGURE 1.2 1.3 1.4 1.4 VENT PIPE PENETRATION THROUGH STRUCTURE WALL WALL WALL WALL AIR INTAKE PIPE PENETRATION THROUGH STRUCTURE WALL WALL WALL WALL VENT PIPE SIZE 3” 3” 3” 4” AIR INTAKE PIPE SIZE 3” 3” 4” 4” MAXIMUM LENGTHVENT BWC070 100ft 100ft BWC090 100ft 100ft BWC120 100ft 100ft BWC151 100ft 100ft BWC150 55ft BWC225 55ft INLET BWC070 100ft 100ft BWC090 100ft 100ft BWC120 100ft 100ft BWC151 100ft 100ft BWC150 60ft BWC225 60ft MINIMUM LENGTHVENT BWC070 2ft 2ft BWC090 2ft 2ft BWC120 2ft 2ft BWC151 2ft 2ft BWC150 2ft BWC225 2ft INLET BWC070 2ft 2ft BWC090 2ft 2ft BWC120 2ft 2ft BWC151 2ft 2ft BWC150 2ft BWC225 2ft VENT TERMINAL TEE (Note #1) CROWN PN 230873 CONCENTRIC TERMINAL TEE (Note #1) TEE (Note #1) AIR INTAKE TERMINAL TEE (Note #1) TEE (Note #1) TEE (Note #1) VENT MATERIAL CPVC + PVC (Note #2) CPVC + PVC (Note #2) CPVC + PVC (Note #2) CPVC + PVC (Note #2) AIR INTAKE MATERIAL PVC PVC PVC PVC Note #1: TEEs may be offset on snorkels as shown in Figure 1.10 Note #2: Firs...
