[. . . ] Remove one of the knockouts from the side of the junction box where the pressure switch is mounted. Install the flexible conduit connector onto the CK-51 junction box and secure with fastening nut. [. . . ] Route the tubing to the CK-51 junction box and connect the tubing to the pressure switch. When routing the tubing, avoid kinking the tubing by bending the tubing too sharply. For remote mounted CK-51 Junction Box, use a 1/4" OD copper, aluminum or plastic tubing and route the tubing to avoid contact with any heat source. Refer to the SWG Venter Installation Instructions for setting system airflow. Figure 1 Figure 2 Figure 3 Figure 4 Page 2 WIRING (See Diagrams A-C State Industries Water Heaters) Wire the venter motor and controls in accordance with the National Electrical Code, manufacturer's recommendations and/or applicable local codes. Check ground circuit to make certain that the unit has been properly grounded. The wiring should be protected by an over current circuit device rated at 15 amperes. CAUTION must be taken to ensure that the wiring does not come into contact with any heat source. All line voltage and safety control circuits, between the venter and the appliance, MUST be wired in accordance with the National Electrical Code for Class I wiring or equivalent methods. You must provide all wiring of the proper size outside of the water heater. You must obey local codes and electric utility requirements when you intall this wiring. This water heater must be electrically `grounded" by the installer. Using a screw on the water heater junction box, a wire must be run to connect the water heater to an uninterrupted metallic ground. [. . . ] Check pressure switch for continuity across terminals, during venter operation. Wheel: Inspect venter wheel annually to clear any soot, ash or coating which inhibits either rotation or air flow. [. . . ]
