[. . . ] Wiring MUST be in accordance with the National Electrical Code and applicable local codes. Before and after adding this safety control on existing appliances, an installation inspection in accordance with the National Fuel Gas Code 54, Z223. 1 Appendix H should be performed and a combustion analysis is recommended to determine the operating condition of the appliance. [. . . ] WIRING CAUTION: When wiring the spillage switch into the burner circuit route the wiring and secure away from any hot surface. Shut off all electrical power and gas supply to the appliance before working with any electrical connections. Disconnect the hot lead between the thermostat or temperature control and the TH terminal on the gas valve or the TH, TH-W or 24V terminal on the ignition module. Check the thermostat anticipator (if applicable) circuit for proper setting. Wire the spill switch or switches into series with this circuit by wiring from the thermostat or temperature control to the spill switch or switches then to the gas valve or ignition module. (See Figure 9 & 10) Figure 7 Figure 8 Figure 9 Figure 10 Page 3 750 MILLIVOLT PILOT GENERATOR APPLICATIONS 1. Disconnect the hot lead between the thermostat and the TH terminal on the gas valve. Wire the spill switch or switches into series with this circuit by wiring from the thermostat to the spill switch or switches then to the TH terminal on the gas valve. On older bleed tube style equipment wire switches in series with one wire of the E. C. O circuit. (See Figure 11) 30 MILLIVOLT WATER HEATER: Two (2) switches are recommended for this application. [. . . ] Allow approximately 2 minutes for the system to back up and the gas burner to shut down. If the spillage switch dose not trip within the 2 minute period, relocate the switch onto the area where the observed highest spillage occurred. [. . . ]
