[. . . ] NOTE: Probe length is designed for mounting on draft hoods up to 6" Dia. To achieve 360° spillage sensing on larger draft hood, an additional switch or switches would be required. Mount the switch box onto the appliance 2 to 3 inches away from the draft hood using two sheet metal screws. (See Figure 1) An alternative mounting method is to mount the switch directly onto the draft hood. [. . . ] Mount the probe tabs around the draft hood, located approximately 120° apart. The bottom of the bent end should be ½ to ¾ inches away from the bottom edge of the draft hood. (See Figure 3) Avoid bending the sensing probe, kinks can alter the switches performance. NOTE: For small draft hoods, multiple wraps around the draft hood is required. (See Figure 4) The bottom of the bent end should be ½ to ¾ inches away from the edge of the draft hood. (See Figure 4) Avoid bending the sensing probe, kinks can alter the switches performance. NOTE: For small draft hoods, double back with the probe using a minimum of a 1 inch radius to bend the probe. Figure 2 Figure 1 Figure 3 Figure 4 Page 2 WIRING Refer to System Check-out Procedure Section before operating. 24 VAC SYSTEMS CAUTION: Disconnect electrical power when wiring Safety Switch. If it is determined there is a condition which could result in unsafe operation, the appliance should be shut off and the owner advised of the unsafe condition. THE FOLLOWING STEPS SHOULD BE FOLLOWED IN MAKING THE SAFETY INSPECTION: 1. Conduct a gas leakage test of the appliance piping and control system downstream of the shut off valve in the supply line to the appliance. Visually inspect the venting system for proper size and determine there is no blockage or restriction, leakage, corrosion, and other deficiencies which could cause an unsafe condition. Shut off all gas to the appliance and shut off any other fuel-gas burning appliance within the same room. Insofar as practical, close all building doors and windows and all doors between the space in which the appliance is located and other spaces of the building. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. If, after completing Steps 8 through 13, it is believed sufficient combustion air is not available, refer to local codes, or in the absence of local codes, to the National Fuel Gas Code, A. N. S. I. Determine that the pilot(s) is burning properly and that main burner ignition is satisfactory by interrupting and reestablishing the electrical supply to the appliance in any convenient manner. [. . . ] Determine that the pilot(s) is burning properly and that main burner ignition is satisfactory by interrupting and reestablishing the electrical supply to the appliance in any convenient manner. Test the pilot safety device to determine it is operating properly by extinguishing the pilot burner(s) when the main burner(s) is off and determine, after 3 minutes, that the main burner gas does not flow upon a call for heat. Visually determine that main burner gas is burning properly: i. e. , no floating, lifting, or flashback. If appliance is equipped with high and low flame controlling or flame modulation, check for proper main burner operation at low flame. [. . . ]
