[. . . ] 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-21 junction box and secure with fastening nut. If remote mounting the CK-21 junction box, mount the flexible conduit connector onto a 2" x 4" installer supplied junction box. Fasten the flexible conduit from the SWG Venter into the conduit connector. [. . . ] CAUTION: Bleed tube MUST be installed with its termination near the main burner. INSTALLATION OF SAFETY SPILLAGE SWITCHES NOTE: Water Heater MUST have safety switches installed. Installation of a SAFETY SWITCH is REQUIRED for water heaters, for the purpose of detecting spillage from a blocked flue system and/or inadequate draft. Bend the tab attached to the spillage switches as shown in Figure 5. Mount the spillage switches along the opening of the draft hood. (See Figure 6) Connect one terminal on each spillage switch with the 8" jumper wire. Then connect the other two terminals to the jacketed wire. Route the jacketed wire along the frame or enclosure of the water heater, keeping the wires away from any HOT surface area. Splice the jacketed wire in series with one of the leads connected to the thermocouple splicing terminal. (See Figure 6) 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 re-starting the system. Figure 4 Figure 5 Figure 6 Page 2 WIRING 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 over current 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 I wiring or equivalent methods. Route the venter motor and control wiring with an appropriate wiring method. Refer to SWG Venter Installation Instructions for setting system airflow. Diagram A Page 3 SYSTEM CHECK-OUT PROCEDURE FOR HOT WATER HEATER CONTROLS WATER HEATER GAS PRESSURE SWITCH 1. Following water heater manufacturer's instructions to light the pilot, turn the gas control valve to the ON position. Open the hot water faucet; this should energize the venter. [. . . ] Check reset buttons on spillage switches. Motor: Inspect motor once a year, the motor should rotate freely. Wheel: Inspect venter wheel annually to clear any soot, ash or coating which inhibits either rotation or air flow. Remove all foreign material before operating. [. . . ]
