[. . . ] 2) Figure 2 Figure 1 PRESSURE SWITCH SENSING TUBE INSTALLATION: 1. 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. [. . . ] Fasten the flexible conduit from the SWG Venter into the conduit connector. Mount the CK-40F junction box or installer supplied junction box onto the wall or floor joist without straining the flexible conduit. Fasten the CK-40F junction box through the four dimpled locations on the base of the box. 3) After venting kit installation and checkout, check the amperage current draw through the thermostat circuit and adjust the thermostat anticipator accordingly. Figure 3 Page 2 Page 3 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 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. LOW VOLTAGE WIRING INSTRUCTIONS FOR BOILERS AND WARM AIR FURNACES: 1. With boilers, locate terminal on spark ignition module or gas valve (if standing pilot) which would normally be 24 volts hot on a call for heat. With spark ignition systems, this terminal could be THW, 24 V, THS or T1 depending on the spark ignition control. With warm air furnaces, locate terminal W in furnace junction box. Remove wire from this terminal and reroute to T1 on CK-40F. With boilers, connect T3 on CK-40F to hot side of gas valve (if standing pilot) or to terminal TH-W, 24 V, THS or T1 if spark ignition. NOTE: Remember, the correct terminal is the one that would normally be hot on a call for heat. With warm air furnaces, connect T3 on CK-40F to terminal W in furnace junction box. Connect T2 on CK-40F to a 24 volt neutral where convenient. [. . . ] This should open the pressure switch contacts and stop burner operation. TROUBLE SHOOTING HINTS 1. Venter does not activate when thermostat calls for heat. Check gas pressure switch for continuity across terminals when gas valve is pressurized. [. . . ]
