[. . . ] INSTALLATION SAFETY INSTRUCTIONS CAUTION: This device must be installed by a qualified installer in accordance with the manufacturer's installation instructions. This combustion air system must be installed by a qualified installer. "Qualified Installer" shall mean an individual who has been properly trained or a licensed installer. Plan the system layout before installation to avoid the possibility of accidental contact with concealed wiring or plumbing inside walls. [. . . ] For assistance in this case, call Field Controls Technical Support at 1-800-742-8368. Example: An oil fired appliance firing at 10. 5 gph where a CAS-7 unit needs to be placed at a location requiring 80 feet of pipe from the StarKap, using two 90 degree elbows: From Diagram B, a vertical line is drawn through the point at 10. 5 gph on the "Oil Firing Rate" scale. For 80 feet of 10" pipe, two 90 degree elbows, and two increaser/ reducers, the equivalent length is 80 + 18 + 18 + 6 + 6 = 128 feet of equivalent length. A horizontal line drawn through the point at 128 feet on the "Equivalent Length" scale intersects the vertical line in the 12" duct region of the diagram. Since the intersection is not in the 10" duct region, recalculate the equivalent length using 12" duct: 80 + 21 + 21 + 7 + 7 = 136 feet of equivalent length. A horizontal line drawn through the 136 point on the "Equivalent Length" scale intersects the vertical line within the 12" duct region of the diagram; therefore, 12" duct will be of sufficient size for the application.

Two mounting brackets are provided for securing the unit against a solid structure, such as a wall, column, or the side of the appliance itself. Use the included screws to attach the brackets to the CAS housing as shown in Figure 1. Secure the brackets to a solid structure with appropriate fasteners. It is not required to use the brackets as long as the unit is located so that it may not be bumped, moved, or tipped over. INTAKE AIR STARKAP LOCATION The StarKap should be located on an outside wall or roof Figure 1 maintaining clearances to other intake and exhaust vents in accordance with the National Fuel Gas Code, ANSI Z223. 1, manufacturer's recommendations and/ors local codes which are applicable. The StarKap should be located at least 10 feet from a building exhaust outlet, equipment vent, or chimney termination. INSTALLATION OF INTAKE AIR STARKAP After determining the location of the StarKap, cut an appropriately sized hole in the wall or roof, taking precautions to avoid interference with wiring or other plumbing in the structure to be cut. Pre-attach a short length of duct to the StarKap if necessary. Insert the StarKap and secure with appropriate fasteners. Flash in the opening in accordance with local building codes. INSTALLATION OF DUCT Refer to Diagram A or B to determine what size pipe is needed. Connect the duct pipe from the top of the CAS unit to the StarKap. If using pipe of different diameter than the CAS component connections, attach increaser/reducer Figure 2 fittings as close to the CAS unit and to the StarKap as possible. [. . . ] EXTERNAL WIRING CONNECTIONS Refer to Figure 4 for typical 120 VAC oil fired burner or Figure 5 for 24 VAC gas fired burner connections that should be used when connecting the CAS unit. Refer to Figure 6 for connecting a single 120 Figure 4 VAC appliance to the CAS, or Figure 7 for 24 VAC. The three wires "BURNER", "WHITE", and "ORANGE" in Figure 4 correspond to the same wires shown in Figures 6 & 10. The three wires labeled 1, 2, and 3 in Figure 5 correspond to the same wires shown in Figures 7-9. [. . . ]
