[. . . ] If additional wiring is required, install the flexible conduit connector onto the installer supplied junction box. Fasten the flexible conduit from the SWG Venter into the conduit connector. Mount the CK-41P control box onto a non-heated vertical surface of the appliance or nearby wall or floor joist through the four dimpled locations on the base of the box. [. . . ] Mount the CK-41P control box onto a non-heated vertical surface of the appliance or nearby wall or floor joist through the four dimpled locations on the base of the box. NOTE: The mounted pressure switch diaphragm must be mounted with a vertical orientation; see label on pressure switch. (See Figure 3) If required, run additional wiring as in figure 2 and connect to CK-41P control box, if required, using the supplied flexible conduit connector and approved connectors and anti-short bushings. Attach the 1/4 inch tubing connector to the pressure tube on the SWG Venter. Route the tubing to the CK-41F junction box and connect the tubing to the pressure switch using supplied plastic nut. When routing the tubing, avoid kinking the tubing by bending the tubing too sharply. Support the tubing at 2' intervals using installer supplied tube clamps. 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. Adjust the thermostat and/or aquastat to call for heat and observe the power venting system for proper operation sequence. After a short delay, the relay is energized, the venter motor starts and the vent damper begins opening. Pressure switch closes, the vent damper reaches the open position and the burner starts. Aquastat is satisfied, the burner stops and the vent damper begins closing. This should open the pressure switch contacts and stop burner operation. If no other voltage, the appliance is not calling for heat to the CK-41P. If there is 24 volts continuously for at least 45 second, there should be 115 volts from N to M. If not, the time relay is defective, or L1 and N are not properly wired. [. . . ] If no other voltage, the appliance is not calling for heat to the CK-41P.
