[. . . ] ITEMS INCLUDED IN KIT: 1 - Junction box with mounted pressure switch and and solid state post purge control 1 - WMO-1 Secondary Safety Switch 1 - Delay oil solenoid valve with preset pre-purge 1 - 2 ft. length of 1/4 inch aluminum tubing 2 - Flexible conduit connector 1 - 1/4 inch tubing connector 2630 Airport Road · Kinston, NC 28504 Phone: 252-522-3031 · FAX: 252-522-0214 www. fieldcontrols. com INSTALLATION AND ADJUSTMENTS MOUNTING JUNCTION BOX: The junction box can be mounted at the venter or remotely mounted away from the venter. Remove one of the knockouts from the side of the junction box where the pressure switch is mounted. [. . . ] 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-65 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-65 Junction Box, use a 1/4" OD copper, aluminum or plastic tubing and route the tubing to avoid contact with any heat source. PROVING SWITCH ADJUSTMENTS: After proper air flow is established, the pressure switch adjustment is made by turning the pressure switch adjustment screw clockwise (See Fig. Turn the adjustment screw counterclockwise until burner ignites. Turn the adjustment screw an additional 1/4 to 3/4 turn counterclockwise to ensure adequate switch adjustment. WARNING: Failure to properly adjust the pressure switch as specified above could lead to improper operation of the pressure switch which will result in a hazardous condition and bodily harm!POST PURGE TIMING ADJUSTMENT: To adjust the post purge time, rotate the timer adjustment on the timer counterclockwise to increase the operation time. To decrease the operation time, rotate the timer adjustment clockwise. 7) Typical post purge time should be between 3 to 5 min. WIRING INSTRUCTIONS CAUTION: DISCONNECT ELECTRICAL POWER WHEN WIRING POWER VENTER 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 one wiring or equivalent methods. Refer to wiring diagrams A and B for typical wiring installations.
