[. . . ] For clearances to combustible materials, multiple appliance venting and other installation requirements, refer to the National Fuel Gas Code A. N. S. I. Z223. 1, and/or any applicable local codes or appliance manufacturer's installation instructions. Diagram B INSTALLATION USING SINGLE WALL VENT PIPE INSTALLATION CLEARANCE WITH SINGLE WALL VENT PIPE DOUBLE PIPE SYSTEM ALLOWABLE INLET TEPERATURE 400°F OR LESS 400°F TO 550°F 400°F TO 550°F CLEARANCE (A) ½ INCH MINIMUM 1 INCH MINIMUM ½ INCH MINIMUM WITH SHEET METAL LINER SINGLE PIPE SYSTEM ALLOWABLE INLET TEMPERATURE 400°F OR LESS 400°F TO 550°F 400°F TO 550°F CLEARANCE (B) 3 INCH MINIMUM 4 INCH MINIMUM 3 INCH MINIMUM WITH SHEET METAL LINER To install an outer pipe extension to the SWG power venter, the end pipe cover on the power venter must be removed. Then, cut a 1-inch square notch into the vent pipe extension before attaching to the power venter. Install the required length of outer pipe extension lengths as needed for clearance to combustible materials. (See Diagram B) The table shows minimum allowable clearances when using single or double pipe systems. When the outer pipe is extended over the inner pipe use the double pipe guidelines when determining clearances. NOTE: Vent pipe joints should be secured with at least (3) three sheet metal screws. Figure 6 Page 6 Figure 7 CLASS B AND CLASS L DOUBLE WALL VENT PIPE INSTALLATION (Follow vent pipe manufacturer's listed or recommended clearances from combustible material. ) 5. Using a hand crimper or a like device, crimp the inner pipe of the SWG power venter approximately 1" long. Attach the vent pipe over the crimped end of the SWG power venter inner pipe. Secure the vent pipe to the SWG power venter inner pipe with at least (3) three #8 sheet metal screws. WIRING INSTRUCTIONS Figure 8 NOTE: Refer to the appropriate wiring diagrams contained in these instructions for the corresponding control system for the water heater being installed. Wire the power venter motor and controls in accordance with the National Electric Code and 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 circuit device rated at 15 amperes. CAUTION MUST be taken to ensure that the wiring does not come in contact with any heat source. All line voltage and safety control circuits, between the power venter and the appliance, MUST be wired in accordance with the National Electrical Code for Class 1 wiring or equivalent. Push the snap bushing supplied over the knockout hole created to prevent the wires from being chafed. Insert the end of the harness with quick connect terminals into the side of the control box. Disconnect the black wire connected to "TH" or "24V" on the ignition module and connect to the fully insulated tab on the black wire from the wiring harness provided. Connect the yellow wire from the harness supplied to the "TH" or "24V" terminal on the ignition module. Connect the red wire from the harness supplied to the upper terminal block (the group of terminals opposite the yellow wire leading to the thermostat). Run the harness supplied along the water heater jacket and support with the clamps provided. (See Figure 9) 7. Figure 9 Page 7 Install the GSK-3 spillage switch on the draft hood with the selftapping sheet metal screw supplied. [. . . ] Use a draft gauge, flame of a match or candle, smoke from a cigarette, cigar or pipe. Shut off heating appliance thermostat and check for spillage around the draft hood and burner inlet air location after power venter has stopped operation. If a flow reversal is noticed, house depressurization is occurring and make up air is required. Turn on all fuel burning appliances within the same room so that they will operate at their maximum input. [. . . ]
