6.

Position the new thermocouple through the bottom opening

of the two piece wire connector (Figure 34). Be sure igniter
wire is positioned through the small opening of the two
piece wire connector.

7.

Re-attach the burner. Note the orientation of the burner

(Figure 33.)

Replacing the Pilot/ Pilot Tube Assembly

1.

Remove the manifold/burner assembly. See “Removing

the Manifold/Burner Assembly.”

2.

Lift the retainer clip straight up from the back of the two

piece wire connector (using a flat-blade screwdriver), then
remove the two piece wire connector from the manifold

door (Figure 34.)

IMPORTANT: Be careful not to bend or alter the position of the

pilot tube. It will be used as a bending template for the new
pilot assembly.

3.

Take off the burner by removing the two (2) screws located

underneath the burner. See Figure 33.

4.

Remove and keep the screw securing the pilot assembly to

the pilot bracket. (Figure 36)

5.

Remove and keep the old pilot tube and thermocouple.

6.

Using the old pilot tube as a guide, bend the new pilot tube

to match the old one. NOTE: Make only the bends closest
to the pilot before going to the next step. (Figure 36)

Connect the new pilot tube and tighten the nut securing it
to the pilot assembly. IMPORTANT: Keep the pilot orifice in
the pilot when making the connection. Do not operate the

water heater without the pilot orifice installed.

Install the thermocouple, making sure that it is fully seated.

Re-attach the pilot assembly to the pilot bracket and secure
using the screw removed earlier.

Re-attach the burner. Note the orientation of the burner
(Figure 33).

Position the new pilot tube through the largest opening of

the two piece wire connector. NOTE: The largest opening
should be located at the top position. The igniter wire
should be located in the middle opening and thermocouple

in the bottom opening (Figure 37).

Reposition the two piece wire connector in the manifold

door opening and secure it with the retainer clip.

14.

Carefully bend the new pilot tube and thermocouple to

match the bend of the manifold tube. NOTE: When bending,
DO NOT crimp or crease the pilot tube or thermocouple.
(Figure 34)

15. Before you proceed to the next step, install the new brass

ferrule nut in the gas control valve/thermostat’s pilot tube
opening. HAND TIGHTEN ONLY.

Cleaning the Combustion Chamber and

Flame-arrestor

1.

Follow procedure outlined in “Removing the Manifold/

Burner Assembly.”

2.

Use a vacuum cleaner/shop vac to remove all loose debris

in the combustion chamber (Figure 38). Use compressed
air to clear any dust or debris that may have accumulated
in the flame-arrestor.

COMBUSTION CHAMBER

Reassemble by following the procedure under “Replacing

the Manifold/Burner Assembly.”
