[. . . ] Fasten the CK-91F junction box through the four dimpled locations on the base of the box. (See Figure 3) 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. [. . . ] 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 Figure 7 result in a hazardous condition and bodily harm!THERMOSTAT HEAT ANTICIPATOR ADJUSTMENT After venting kit installation and checkout, check the amperage current draw through the thermostat circuit and adjust the thermostat anticipator accordingly. INSTALLATION OF GAS PRESSURE SWITCH CAUTION: Check gas control valve pressure. Pressure MUST NOT exceed 14" WC pressure. (See Figure 8) NOTE: If installing on an existing appliance, shut off gas supply to gas valve before plug removal. Replace the pressure tap plug with the 1/8" pipe nipple and pipe tee. Install pressure tap plug at the bottom of the pipe tee. Install the gas pressure switch into the side of the pipe tee. The gas pressure switch is supplied with a restrictor orifice in the inlet and outlet ports. With these orifices in place, the switch does not need to be vented. This feature complies with current ANSI standards for gas regulators. 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. Figure 10 DRAFT HOOD SAFETY SWITCH INSTALLATION PROCEDURE Figure 11 NOTE: 12 ga. wire should be used when wiring safety spillage switches, to reduce the voltage drop in the thermocouple circuit. Remove the thermocouple from the gas control valve. Thread the junction block into the thermocouple port and thermocouple into the bottom of the junction block. Connect lead wire from the junction block to the jacketed lead wires or wire enclosed in an accepted wiring enclosure. (See Figure 11) NOTE: Draft spillage switches should be mounted 90 degrees apart, and mounted opposite from the vent outlet direction. Mount the two spillage switches onto the draft hood and connect inside terminals of switches with jumper wire. Connect outside terminals to lead wires which are connected to the thermocouple junction block. Route jacketed lead wires or accepted wiring enclosure on the outside of the water heater enclosure. [. . . ] Adjust the thermostat to call for heat with the venter inoperative. Allow approximately 2 minutes of flue gas spillage for the spillage switches to sense the spillage and disrupt the thermocouple circuit, halting the gas flow to the pilot and burner. Reset the spillage switches and light the pilot, then perform a second safety spillage test (Steps 1 and 2). 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.
