Replacing the Thermocouple
1.Remove the manifold assembly as directed previously.
2.Remove the retainer clip from the back of the two piece wire connector and remove the two piece wire connec- tor from the manifold door (Figure 25).
3.Pull the thermocouple from the pilot assembly (Figure 29).
IMPORTANT: Be careful not to bend or alter the position of the pilot assembly components.
4.Push the new thermocouple through the holes in the pi- lot bracket. Insert the thermocouple tube into the holes provided in the pilot assembly until it clicks into place.
5.Position the new thermocouple through the larger opening of the two piece wire connector (Figure 25). Be sure igniter wire is positioned through the small open- ing of the two piece wire connector.
