[. . . ] Remove one of the knockouts from the side of the junction box where the pressure switch is mounted. Install the flexible conduit connector onto the CK-50 junction box and secure with fastening nut. If remote mounting the CK50 junction box, mount the flexible conduit connector onto a 2" x 4" installer supplied junction box. [. . . ] PROVING SWITCH ADJUSTMENTS: After proper air flow is established, the pressure switch adjustment is made by turning the pressure switch adjustment screw clockwise (See Fig. Turn the adjustment screw counterclockwise until burner ignites. 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 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. Figure 4 Figure 2 Figure 1 Figure 3 Page 2 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. The wire connections which must be made on a Sidewall Fan can be divided into two categories; Power Connections and Control Voltage. POWER CONNECTIONS The Power Connections bring 120 volts into the fan control box from a designated power source and then sends the same 120 volts out to the fan motor. Step 1 Step2 CONTROL VOLTAGE The Control Voltage brings 120 volts and 24 volts from the boiler to start the fan and make a proving switch, respectively. Step 1 Locate an access panel below the gas train on the left side of the boiler. Remove the access panel and expose the terminal strip and the 2-pin molex plug (brown and white wires). Connect the black and white wire from the fan control box to the 2-pin molex plug. Connect the orange and blue wire from the fan control box to the 'B' and 'X' on the terminal strip. [. . . ] While system is operating, disconnect power to the venter motor. This should open the pressure switch contacts and stop burner operation. Venter does not activate when thermostat calls for heat: a. [. . . ]
