[. . . ] WATER HEATER CONTROL KIT Model: CK-21 Designed for use on SWG Series Power Venters for controlling Natural Gas and L. P. Gas Instantaneous Water Heaters with a pressure tap port. ITEMS INCLUDED IN KIT: 1) Junction box 1) Fan control gas pressure switch 1) 1 Ft. Length of 1/4 inch aluminum tubing 1) 1/8" NPT x 3 inch pipe nipple 1) 1/8" NPT x 1/4 inch OD tubing elbow 1) 1/8" NPT pipe tee 1) 6 Foot length of 12-2 wire 1) 8 Inch jumper wire 1) Flexible conduit connector 2) Spillage Switches 3) Adhesive Tabs DO NOT DESTROY THESE INSTRUCTIONS MUST REMAIN WITH EQUIPMENT MOUNTING JUNCTION BOX The junction box can be mounted at the venter or remotely mounted away from the venter. [. . . ] Then install the 3" x 1/8" NPT nipple, pipe tee and pressure tap plug. Next, install the brass elbow into the switch vent on the Pressure Switch. Install the bleed tube into the brass elbow; then route the tubing up and terminate it near burner. CAUTION: Bleed tube MUST be installed with its termination near the main burner. INSTALLATION OF SAFETY SPILLAGE SWITCHES NOTE: Water Heater MUST have safety switches installed. Installation of a SAFETY SWITCH is REQUIRED for water heaters, for the purpose of detecting spillage from a blocked flue system and/or inadequate draft. (See Figure 6) Connect one terminal on each spillage switch with the 8" jumper wire. Route the jacketed wire along the frame or enclosure of the water heater, keeping the wires away from any HOT surface area. Splice the jacketed wire in series with one of the leads connected to the thermocouple splicing terminal. (See Figure 6) 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 re-starting the system. Figure 4 Figure 5 Figure 6 Page 2 WIRING 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 over current 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 I wiring or equivalent methods. [. . . ] Wheel: Inspect venter wheel annually to clear any soot, ash or coating which inhibits either rotation or air flow. Vent System: Inspect all vent pipe connections annually for looseness and for evidence of flue gas leakage. Seal or tighten pipe connections if necessary.
