[. . . ] Wiring should be in accordance with the manufacturer's recommendations, National Electrical Code and applicable local codes. NOTE: For 30 Millivolt Wiring Applications, the TCA-1 Thermocouple Adapter must be ordered sparately. [. . . ] After installing the safety switch, check the amperage drown through the thermostat circuit and adjust the thermostat anticipator accordingly. Diagram A MILLIVOLT WIRING SYSTEMS CAUTION: Shut off main gas supply to appliance before wiring. Thread TCA-1 thermocouple adapter into thermocouple port, then thread the thermocouple into the bottom of the TCA-1. Connect lead wires (NOTE: 12 GA wire should be used) from the TCA-1 thermocouple adapter to the leads on the thermal switch. (See Diagram B) 750 MILLIVOLT SYSTEM Wire the TSP-1 thermal switch in series with one side of the thermostat circuit (See Diagram C) or pilot generator circuit. Light the appliance burner in accordance with manufacturer's instructions. Operate the appliance to determine that the appliance will operate continuously. Allow system to cool down, then remove the vent pipe connection near the appliance. Allow approximately 2 minutes for the system flue gases to back up and the gas burner to shut off. Push the reset on the spillage switches, then relight appliance and perform Steps 3 & 4 again. Re-connect vent pipe connection and cycle system 2 to 3 times to ensure continuous operation. NOTE: Shutdown of appliance burner should not be more than 10 minutes. PRE-INSTALLATION INSPECTION INSTRUCTIONS FOR EXISTING APPLIANCES RECOMMENDED PROCEDURE FOR SAFETY INSPECTION OF AN EXISTING APPLIANCE INSTALLATION BY THE NATIONAL FUEL GAS CODE 54, Z223. 1 APPENDIX H: The following procedure is intended as a guide to aid in determining that an appliance is properly installed and is in a safe condition for continuing use. This procedure is predicated, on central furnace and boiler installations, and it should be Page 3 Figure 5 Figure 6 Diagram B Diagram C recognized that generalized procedures cannot anticipate all situations. Accordingly, in some cases deviation from this procedure may be necessary to determine safe operation of the equipment: a. [. . . ] Turn on all other fuel-gas burning appliances within the same room so they will operate at their full inputs. Return doors, windows, exhaust fans, fireplace dampers, and any other fuel-gas burning appliance to their previous conditions of use. [. . . ]
