Replacing the Thermocouple                                     
1.  Remove the manifold/burner assembly as directed 
previously.
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 25.)
3.  Remove the burner, see Removing the Burner from the 
Manifold/Burner Assembly. 
4.  Pull the thermocouple from the pilot assembly (Figure 26).
IMPORTANT: Be careful not to bend or alter the position of 
the pilot assembly components.
5.  Insert the thermocouple tip into the holes provided in 
the pilot bracket until it clicks into place. NOTE: The 
base of the thermocouple must be flush with the base 
of the pilot bracket.
6.  Position the new thermocouple through the bottom 
opening of the two piece wire connector (Figure 28). 
Be sure igniter wire is positioned through the middle 
opening of the two piece wire connector.
7.  Re-attach the burner. Note the orientation of the buner 
(Figure 24.)
8.  See Replacing the Manifold/Burner Assembly.

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 25.)
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 24.
4.  Remove and keep the screw securing the pilot 
assembly to the pilot bracket. (Figure 27)
5.  Remove and keep the old pilot/pilot tube assembly.
6.   Using the old pilot/pilot tube assembly as a guide, bend 
the new pilot tube and new thermocouple to match the 
old ones. NOTE: Make only the bends closest to the 
pilot before going to the next step. (Figure 27)

7.  Route the new pilot tube, thermocouple, and igniter wire 
through the manifold/burner door opening. (Figure 25)
8.  Re-attach the pilot assembly to the pilot bracket and 
secure using the screw removed earlier.  
9.  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 28)
