[. . . ] Install the flexible conduit connector onto the CK-62 Junction Box and secure with fastening nut. If remote mounting the CK-62 Junction Box, mount the flexible conduit connector onto a 2" x 4" installer supplied junction box. Fasten the flexible conduit from the SWG Venter into the conduit connector. Mount the CK-62 Junction box or installer supplied junction box onto the wall or floor joist without straining the flexible conduit. [. . . ] (See Figure 7) CHART A Close on 150°F to rise temperature 200°F ± 15°F Open on 95°F to fall temperature 130°F ± 15°F Typical post purge time should be 3 to 5 minutes Figure 7 Figure 6 Page 3 WIRING INSTRUCTIONS 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. Route the venter motor and control wiring with an appropriate wiring method. Refer to the Wiring Diagrams A through E.

Attach the 1/4 inch tubing connector to the pressure tube on the SWG Venter. Connect the supplied 1/4" aluminum tubing to the tubing connector. Route the tubing to the CK-62 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-62 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. PRESSURE SWITCH ADJUSTMENTS With the venter air flow set and the appliance operating at the best operating efficiency, adjust the pressure switch by rotating the adjustment screw clockwise until the burner shuts off, then rotate the adjustment screw counterclockwise until the burner fires. Rotate the adjustment screw an additional 1/4 turn counterclockwise to ensure proper switch setting. (See Figure 8) Figure 8 SYSTEM CONTROL CHECK OUT PROCEDURES 1. Adjust the thermostat to call for heat and observe the power venting system for proper operation sequence (Repeat if necessary). Relay is energized and venter motor starts. Pressure switch closes and burner starts. Thermostat is satisfied, burner stops and venter motor should operate for approximately 3 to 5 minutes. [. . . ] Check for negative pressure in building. Motor: Inspect motor once a year; the motor should rotate freely. Wheel: Inspect venter wheel annually, for oil fired heating systems, clear any soot, ash or coating which inhibits either rotation or air flow. Remove all foreign material before operating. [. . . ]
