Using a phillips head screwdriver remove the 2 screws attaching the burner to the manifold pipe (saving screws for reinstallation later) (Figure 99). Installing New Burner : 12. Care MUST be taken to ensure the burner is installed correctly on the inner door/manifold assembly. Position the new burner upside down with the orientation of the burner’s condensation drain as shown in illustration (Figure 99). 13. Align the screw holes on the inner door/manifold assembly. Using the two screws removed in step 11, installed the new burner to the inner door/ manifold assembly (rotate the assembly to visually check the top portion of the burner assembly and confirm the orientation of the condensation drain hole on the top of the burner is toward the back as shown in the illustration) (Figure 99). Installation Caution Must Be Taken: 14. Prior to installing the new inner door/manifold/ burner assembly, look inside the burner chamber to fully understand the correct positioning of the burner assembly and burner manifold tab. It may be necessary to use a flashlight to ensure correct placement. Care must be taken so as to not damage any electrical wiring, components or the air pressure tubing as you are installing the new inner door/manifold/burner assembly. Extra caution should be taken to ensure that electrical wiring, air hose, fiberglass insulation nor any other object is between door gasket and combustion chamber shield. Reinstalling The Inner Door/Manifold/Burner Assembly 15. Insert the manifold/burner assembly in the burner chamber compartment, making sure that the tip of burner manifold tab engages in the slot of the bracket (Figure 98). The tip end of the burner manifold MUST be placed in the slotted portion under the condensation pan to obtain proper installation (Figure 98). Figure 97. 1/4” HEX HEAD SCREW Figure 98.

After confirming no material of any type are between door gasket and combustion chamber shield, align the screws on the inner door with the screw holes on the combustion chamber and tighten with 1/4” nut driver or 1/4” socket & ratchet (Figure 97). After tightening the inner door screws, visually inspect area around door gasket and skirt for spaces or gaps. The door gasket MUST be sealed completely in order for the water heater to perform properly. DO NOT OPERATE THE WATER HEATER IF THE DOOR GASKET DOES NOT CREATE A SEAL BETWEEN MANIFOLD DOOR AND COMBUSTION CHAMBER. 17. Reconnect the manifold tube to the gas control valve/ thermostat (Note: Do Not apply any thread sealant at this connection). To prevent any cross threading the manifold tube should be started by hand (turn clockwise -natural gas). Upon tightening with the fingers and confirming it has not been cross threaded, tighten nut with an 3/4” open end wrench or crescent wrench (Figure 100). 18. Reconnect all the electrical connections to the bottom of the gas control valve/thermostat, gently pushing each connector up snapping into place (Figure 100). 19. Reconnect the electrical flag terminals and air pressure tubing to pressure switch (Figure 101). 20. Turn on the electrical and the gas supplies to the water heater. Plug in the electric connection from the transformer to the electric outlet (Figure 94). 21. Restart the water heater by following the directions on the “Lighting and Operating Instructions” label located on the front of the water heater. 22. As the burner is heating (view flames through viewport), test the manifold tube connection at the gas control valve/thermostat by brushing on an approved noncorrosive leak detection solution (IMPORTANT: Do Not splash any solution onto any electrical connections) (Figure 100). 23. Upon verifying proper operation of the water heater, replace the manifold cover/outer door. Figure 101.

UNPLUGGED Important: Use only factory authorized replacement parts. If you lack the necessary skills to properly perform the installation, you should not proceed, but get help from a qualified service technician. Tools required: 3/4” Open-End Wrench or Crescent Wrench, Phillips Head Screwdriver, Ratchet with 1/4” socket or 1/4” Nut Driver, Ratchet with 1/2” socket. Removing the Inner Door/Manifold/Burner Assembly: 1. Set the gas control valve/thermostat to its lowest setting by pressing the “COO...
