[. . . ] NOTE: The mounted pressure switch diaphragm must be mounted with a vertical orientation; see label on pressure switch. (See Figure 3) If required, run additional wiring as in figure 2 and connect to CK-92* control box, if required, using the supplied flexible conduit connector and approved connectors and anti-short bushings. PRESSURE SWITCH SENSING TUBE INSTALLATION 1. Attach the 1/4 inch tubing connector to the pressure tube on the SWG Venter. [. . . ] Secure them to the enclosure with an accepted hold down tab. Keep wiring away from any HOT surface Figure 9 area. WIRING 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 overcurrent 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. Route the venter motor and control wiring with an appropriate wiring method. INTERNAL WIRING FOR CK-CONTROL KIT Diagram A Page 4 Diagram B L1 to 1 on post purge timer M to 3 on post purge timer T1 to common on pressure switch LOW VOLTAGE BOILERS: 1. WIRING INSTRUCTIONS FOR T2 to timer relay base T3 to N/O on pressure switch Timer base to common on pressure switch Route the appliance's vent damper cable to the CK-92*. Plug the cable into the receptacle located inside the CK-92* using the supplied plastic knockout grommet (if the cable does not have a conduit connector). Connect the CK-92*'s pre-wired damper cable to the vent damper (See Diagram A). Snap the end of the flexible conduit into place on the vent damper conduit bracket. If Figure 10 the damper has a round type motor assembly and does not have a conduit bracket (See Diagram A), install the supplied conduit bracket using the supplied #6 screws and nuts (See Figure 10). If it has a Figure 11 rectangular or "box-like" motor assembly, refer to Fig. Connect 120 volts hot power source wire to terminal L1 on CK-92*. Connect 120 volts neutral power source wire and white wire from venter motor to terminal N on the CK-92*. Connect black wire from venter motor to terminal M on the CK-92*. Wire gas pressure switch terminals COM and NO to L1 and M respectively, per local and national electrical code requirements. [. . . ] Check for negative pressure in building. Venter activates but burner does not fire after a minimum of 45 second continuous call for heat: a. Make sure the vent damper is in open position. Check for 24 volts from both yellow wires on pressure switch to black wire on base of timer relay. [. . . ]
