If a tee fitting is used, it shall be installed in conformance with one of the methods of installation shown in Figures 9,10 and 11. fIGure 9. Gas pIpInG wIth fleXIBle connector. fIGure 10. Gas pIpInG wIth all BlacK Iron pIpe to Gas control. Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated in the piping. The drip leg must be readily accessible. Install in accordance with the “Gas Piping” section. Refer to the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54. whIte-rodGers fuel conversIon InstructIons froM natural Gas to propane (l.p.) Gas Fuel conversions shall be completed by a qualified service agency in accordance with the detailed conversion instructions and all applicable codes and requirements of the authority having jurisdiction. The information in these instructions must be followed to minimize the risk of fire or explosion and to prevent property damage, personal injury or death. The qualified service agency is responsible for the proper installation of this kit. The installation is not proper and complete until the operation of the appliance is checked as specified in the manufacturer’s instructions. 1. Read and follow detailed conversion instructions below and also on the heater. 2. The conversion kit with necessary parts are in a bag attached to the side of the water heater. 3. Shut off the gas supply to the water heater. 4. Remove the outer door. 5. Rotate the thermostat dial on the water heater control counterclockwise ( ) until the main burner ignites and burns off all residual gas in the control and supply lines. 6. Rotate the thermostat dial clockwise ( ) back to the “PILOT LIGHTING” position. 7. Turn the gas control knob “A” to “PILOT”. Depress knob slightly and rotate to “OFF” position, see Figure 12. alternatIve sedIMent trap locatIon fIGure 11. fIGure 12. 8. Unplug wire from igniter assembly mounted to the top of the gas valve. 14 9. Remove flange nuts holding inner door in place with 3/8” nut 15. Remove the Phillips-head screw holding the pilot bracket to the driver, see Figure 13. burner head, see Figure 16. fIGure 13. 10. Loosen flare nut “T” holding thermocouple to bottom of gas valve with 3/8” open-end wrench and pull down to remove, see Figure 14. 11. Loosen flare nut “P” holding pilot line to bottom of gas valve with 7/16” open-end wrench and pull tube down to remove, see Figure 14. 12. Loosen flange nut “B” holding burner tube to bottom of gas valve with 3/4” open-end wrench and pull down to remove, see Figure 14. fIGure 14. 13. Grasp burner tube and remove burner assembly through inner door opening. 14. To remove the natural gas pilot assembly, remove the Phillips- head screw holding the TCO bracket to the burner tube bracket, see Figure 15. fIGure 16. 16. Remove the two Phillips-head screws holding the natural burner head to the burner tube assembly, see Figure 17. 17. Using 3/8” boxed-end wrench remove the natural gas burner orifice “O” from the burner tube. Install burner orifice marked “LP” and tighten securely, see Figure 17. 18. Locate and install the propane burner head to the burner tube using the two Phillips-head screws, see Figure 17. fIGure 17. 19. Push the natural gas pilot assembly grommet out of the inner door towards the combustion chamber. 20. To install the propane pilot assembly, put the igniter wire, thermostat lead, and pilot tube through the inner door hole. Reinstall the Phillips-head screw securing the TCO bracket to the burner tube. Reinstall the Phillips-head screw securing the pilot assembly to the burner head bracket. 21. Push the grommet into the inner door hole making sure the door fits into the groove in the grommet. 22. Reinstall the burner assembly through the door opening being careful not to damage the door gasket on the studs. Position end of burner tube inside bracket as shown in Figure 18. fIGure 15. fIGure 18. 15 23. Place screwdriver in slot “C”, see Figure 19. Depress and turn counterclockwise ( ) to stop. Control screw must be in “IN” position for propane (LP) gas and in “OUT” position for natural gas. STOP! Read label “For Your Safety” located on your water heater. fIGure 19. 24. Light pilot following the lighting and operating instructions on the front surface of the heater. 25. Install outer door. whIte-rodGers fuel conversIon InstructIons froM propane (l.p.)
