[. . . ] Mount the CK-51 junction box or installer supplied junction box onto the wall or floor joist without straining the flexible conduit. Fasten the CK-51 junction box through the four dimpled locations on the base of the box. (See Figure 3) GSK-3 SAFETY SWITCH INSTALLATION Installation of a secondary SAFETY SWITCH is recommended by LP and Natural gas fired systems with a draft hood. This device is installed to detect flue gas spillage from a blocked flue system and/or inadequate draft. [. . . ] Route lead wires along the appliance wall with an accepted wiring enclosure in accordance with the National Electrical Code and applicable local codes, keeping the wires away from any HOT surface area. Wire the safety spillage switch into one side of the thermostat circuit. After installing the safety spillage switch, check the amperage through the thermostat circuit and adjust the thermostat anticipator accordingly. CAUTION: If for any reason the system has shut down during operation, the cause of the system failure should be investigated and corrected before resetting the safety switch and restarting the system. 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. Route the tubing to the CK-51 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-51 Junction Box, use a 1/4" OD copper, aluminum or plastic tubing and route the tubing to avoid contact with any heat source. Relay is energized and venter motor starts. Pressure switch closes and burner starts. Thermostat is satisfied burner and venter motor stop. While system is operating disconnect power to the venter motor. This should open the pressure switch contacts and stop burner operation. (If GSK-3 switch is installed) Allow vent system to cool. Disconnect the vent pipe between the venter inlet and the appliance outlet. Block the vent pipe with a noncombustible material. Activate the heating system with the main burner operating. Allow approximately 2 minutes or less for the secondary safety switch to deactivate the burner. [. . . ] Main burner does not fire when thermostat calls for heat with venter operating. 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.
