Installation Caution Must Be Taken:
10.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.
Installing New Inner Door/Manifold/Burner Assembly
11.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 86).
The tip end of the burner manifold MUST be placed in the slotted portion under the condensation pan to obtain proper installation (Figure 86).
12.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 85). 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.
13.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
14.Reconnect all the electrical connections to the bottom of the gas control valve/thermostat, gently pushing each connector up snapping into place (Figure 87).
15.Reconnect the electrical flag terminals and air pressure tubing to pressure switch (Figure 88).
16.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 82).
17.Restart the water heater by following the directions on the “Lighting and Operating Instructions” label located on the front of the water heater. Test gas connections by brushing on an approved nonconcorrosive leak detection solution.
18.Upon verifying proper operation of the water heater, replace the manifold cover/outer door.
