User manual FIELD CONTROLS 46144900 CK-61

[. . . ] Install the flexible conduit connector onto the CK-61 Junction Box and secure with fastening nut. If remote mounting the CK-61 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-61 Junction box or installer supplied junction box onto the wall or floor joist without straining the flexible conduit. [. . . ] When routing the tubing avoid kinking the tubing by bending the tubing too sharply. For remote mounted CK-61 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 5 Figure 3 Figure 2 Figure 1 Figure 4 Page 2 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.

Rotate the adjustment screw an additional 1/4 turn counterclockwise to ensure proper switch setting. (See Figure 6) POST PURGE TIMING ADJUSTMENT To adjust the post purge time, rotate the timer adjustment on the timer clockwise to increase the operation time. To decrease the operation time, rotate the timer adjustment counterclockwise. (See Figure 7) Typical post purge time should be between 3 to 5 min. Adjust the thermostat to call for heat and observe the power venting system for proper sequence of operation: (Repeat if necessary). Relay is energized, post purge timer is energized, and venter motor starts. Pressure switch closes and burner starts. Thermostat is satisfied, relay is de-energized, burner stops and post purge timer operates venter motor for approximately 3 to 5 minutes. While system is operating, disconnect power to the venter motor. This should open the pressure switch contacts and stop burner operation. [. . . ] Check wiring connections between pressure switch and burner. Check pressure switch for continuity across terminals, during venter operation. Venter does not activate when thermostat calls for heat. Jump wire the terminals L1 and M to ensure motor operation. [. . . ]
