Installation of a spillage SAFETY Switch is recommended for LP and Natural gas fired systems with draft
hoods, draft diverter, or gas barometric draft controls. This device is installed to detect flue gas spillage
caused by a blocked flue system and/or inadequate draft. This device MUST be installed by a qualified
installer in accordance with the manufacturer's installation instructions. 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.
CAUTION: Disconnect Electrical Power When Wiring Spillage Switch

- Page 2 2 1/2 inches from the opposite ends and sides of the draft hood opening. (See Figure 1) 2. The switch should not contact the metal. They should be mounted at least 3/4 inch below the hood opening. (See Figure 2) Mount with supplied sheet metal screw.
- Page 3 (See Figure 8) 3. 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 blocked flue condition.
- Page 4 3. Mount the two (2) spill switches onto the draft hood so the switches do not contact any metal. (See Figure 13) 4. Connect the one terminal of each switch with 12 ga wire and then connect it to the thermocouple junction block. Next,connect the two remaining terminals together using a short length of 12 ga wire.
