[. . . ] Fasten the flexible conduit from the SWG Venter into the conduit connector. Mount the CK-63 Junction box or installer supplied junction box onto the wall or floor joist without straining the flexible conduit. Fasten the CK-63 Junction Box through the four dimpled locations on the base of the box. (See Figure 3) OIL FIRED SECONDARY SAFETY SWITCH Installation of a SECONDARY SAFETY SWITCH is recommended for detecting a blocked flue system and/or inadequate draft. [. . . ] 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. (Diagrams A through F) NOTE: Control is factory set for 120V wiring. For 24V wiring connect the yellow mode wire to the 24V terminal. A resistor has been supplied for 24V power stealing thermostats. (Refer to Figure 6A for installation of resistor) (See Wiring Diagram G for 24V gas furnace applications) NOTE: Circuit board is polarity sensitive. Follow check-out procedures.

Rotate the adjustment screw an additional 1/4 to 1/2 turn counterclockwise to ensure proper switch setting. (See Figure 7) 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 8) Typical post purge time should be between 3 to 5 minutes. If running burner simultaneous with venter, 1-3 minutes is suggested. 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. When the pressure switch closes with a call for heat, the LED light will come on. This indicates that the burner should be in a burn cycle. Thermostat is satisfied, burner stops and venter motor should operate for the set post purge time. The LED should not be on during the post purge. While system is operating, disconnect power to the venter motor. This should open the pressure switch contacts and stop burner operation. [. . . ] Main burner does not fire when thermostat calls for heat with venter operating. (LED should be lit when there is voltage from T1 ­ T2 and the pressure switch is closed. ) b. Check wiring connections between pressure switch and burner. Check pressure switch for continuity across terminals, during venter operation. [. . . ]
