Remove one of the knockouts from the side of the junction box where the pressure switch is mounted. Install the flexible conduit connector onto the CK-92F junction box and secure with fastening nut. [. . . ] INSTALLATION OF GAS PRESSURE SWITCH CAUTION: Check gas control valve pressure. (See Figure 5) NOTE: If installing on an existing appliance, shut off gas supply to gas valve before plug removal. Replace the pressure tap plug with the 1/8" pipe nipple and pipe tee. The gas pressure switch is supplied with a restrictor orifice in the inlet and outlet ports. CAUTION: If for any reason the system has shut down during operation, the cause of the system failure should be investigated and corrected before resetting the safety switch and restarting the system. wire should be used when wiring safety spillage switches, to reduce the voltage drop in the thermocouple circuit. Thread the junction block into the thermocouple port and thermocouple into the bottom of the junction block. Connect lead wire from the junction block to the jacketed lead wires or wire enclosed in an accepted wiring enclosure. (See Figure 8) Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Page 3 NOTE: Draft spillage switches should be mounted 90 degrees apart, and mounted opposite from the vent outlet direction. Mount the two spillage switches onto the draft hood and connect inside terminals of switches with jumper wire. Connect outside terminals to lead wires which are connected to the thermocouple junction block. Route jacketed lead wires or accepted wiring enclosure on the outside of the water heater enclosure. Wire the venter motor and controls in accordance with the National Electrical Code, manufacturer's recommendations and/or applicable local codes. Check ground circuit to make certain that the unit has been properly grounded. The wiring should be protected by an overcurrent circuit device rated at 15 amperes. CAUTION must be taken to ensure that the wiring does not come into contact with any heat source. All line voltage and safety control circuits, between the venter and the appliance, MUST be wired in accordance with the National Electrical Code for class one wiring or equivalent methods. Route the venter motor and control wiring with an appropriate wiring method.

With boilers, locate terminal on spark ignition module or gas valve (if standing pilot) which would normally be 24 volts hot on a call for heat. [. . . ] Allow the water heater to heat up to operating temperature, then disconnect the power to the gas pressure switch. Allow approximately 2 minutes of flue gas spillage for the spillage switches to sense the spillage and disrupt the thermocouple circuit, halting the gas flow to the pilot and burner. Reset the spillage switches and light the pilot, then perform a second safety spillage test (Steps 1 and 2). CAUTION: If for any reason the system has shut down during operation, the cause of the system failure should be investigated and corrected before resetting the safety switch and restarting the system.
