[. . . ] (See Figure 2) Mount with supplied sheet metal screw. BUILT-IN DRAFT HOOD (See Figures 3 & 4) 1. [. . . ] Mount the switch with the supplied #5-40 machine screw and nut. Note, the head of the screw is to be on the inside of the ring. Swing the gate to make sure the gate does not hit the screw head or the switch. NOTE: Mounting the spill switch on the top of the draft control ring will function properly, but will react slower during a block flue condition. 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. CAUTION: Never wire to the 24V GND terminal. 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. On older bleed tube style equipment split one lead of the E. C. O. 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. [. . . ] Flue gases should be emitting from draft control, draft diverter or draft hood. Note the location of the most flue gas spillage. [. . . ]
