25.Install the air intake chamber box by rotating the top of the air intake chamber box from left to right (only a few inches in both directions) while pressing on the bottom portion of the air intake chamber box. When properly installed the air intake chamber box will be in place against the water heater’s side aligning with the screw holes.

26.Secure the air intake chamber box to the water heater’s side by reusing the 4 screws removed in step 13 (Figure 53).

Installing the Fan in the Air Intake Chamber Box:

27.Plug the electrical connections of the fan into the wiring harness: Align the electrical connections in such a position as to ensure the locking portions of the connections are on the same side. Gently push the electrical connectors together until the snap lock on the wiring harness engages the angular lock on the fan connector. Do Not use undue force in pushing these connectors together (Figure 54). (Note: Connectors are designed in such a manner if the connection is not properly aligned they will not lock together).

28.Replace the fan inside the air intake chamber box. It is imperative that the square portion of the fan air outlet be placed inside the raised square portion of the air intake chamber fan compartment (Figure 55).

29.Ensuring the fan is properly aligned in the air intake chamber, secure the fan in place using the 2 screws removed in step 9 (Figure 55).

30.Route the wiring inside the fan box to the outer edge of the fan in such a manner to ensure it will not be pinched or damaged upon installation of the air intake screen (Figure 55).

31.Install the air intake chamber screen, ensuring that the prongs of the lower portion of the air intake chamber screen are in place in the holding slots. Using the 2 screws removed in step 6, secure the air intake chamber screen (Figure 56).

32.Reattach the 3-wire wiring harness connector to the gas control valve (Figure 47).

33.Check the air hose tubing connection to the pressure switch to ensure the tubing has not loosen up or pulled off.

34.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 46).

35.Restart the water heater by following the directions on the “Lighting and Operating Instructions” label located on the front of the water heater.

36.Upon verifying proper operation of the water heater, replace the manifold cover/outer door.
