[. . . ] Fasten the CK-91F junction box through the four dimpled locations on the base of the box. 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-91F junction box and connect the tubing to the pressure switch. [. . . ] WHAT DRAFT SETTING TO USE When adjusting the control, two things are essential; 1. The burner must be operating for at least 10 minutes to obtain maximum chimney draft. An analysis of the flue gases is necessary to determine the percentage of CO2 and check for presence of CO. Refer to the appliance instructions and/or to the local gas company for the proper CO2 readings and allowable CO levels. A rule of thumb for draft setting is between . 01" to . 03" of water column draft at the appliance outlet. (Check equipment requirement. ) Changes in the adjustment of the 4" MG1 control should be made by adding or removing the washer-like weights (supplied with the control) to or from the weight holder chain assembly. After the control is adjusted, it's action will be entirely automatic, the gate will open or close by itself to correct for changes in the draft that occur in the chimney. Page 3 ADJUSTMENTS PROVING SWITCH ADJUSTMENTS After proper airflow is established, the pressure switch adjustment is made by turning the pressure switch adjustment screw clockwise (See Figure 7) until burner operation stops. 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. (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. The gas pressure switch is supplied with a restrictor orifice in the inlet and outlet ports. 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. 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. [. . . ] Refer to the SWG Venter installation instructions for setting system airflow.

This should open the pressure switch contacts and stop burner operation. Page 6 PRESSURE SWITCH FOR WATER HEATER 1. Then adjust the thermostat to call for heat, which will energize the venter motor. Turn gas control valve to the PILOT position, which will start a 1 to 3 min. [. . . ]
