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.
Take off the burner by removing the two (2) screws located
underneath the burner. See Figure 33.

the pilot when making the connection. Do not operate the
water heater without the pilot orifice installed.
Install the thermocoupte, making sure that it isfully seated.
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)
