1.  Take off the burner by removing the two (2) screws 

located underneath the burner.

2.  Check the burner to see if it is dirty or clogged. The 

burner may be cleaned with soap and hot water.

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.

3.  Remove the burner, see Removing the Burner from 

the Manifold/Burner Assembly. 

4.  Pull the thermocouple from the pilot assembly.

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. 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 

burner.

8.  See Replacing the Manifold/Burner Assembly.

1.  Turn off the gas supply to the water heater at the 

manual gas shut-off valve. This valve is typically 

located beside the water heater. Note the position 

of the shut-off valve in the open/on position then 

proceed to turn it off.

2.   On the lower front of the water heater locate the gas 

control valve/thermostat. Before performing any 

maintenance, it is important to turn the temperature 

dial on the gas control valve/thermostat to its lowest 

setting.

3.   On top of the gas control valve/thermostat turn the 

gas control knob to the “OFF” position. NOTE: On 

the White-Rodgers® gas control valve/thermostat 

the knob stop must first be depressed before turning 

the gas control knob. See Lighting Instructions on 

the water heater.

4.  Remove the outer door.
5.  Remove the two screws securing the manifold 

door assembly to the combustion chamber.

6.  Disconnect the thermocouple (right-hand thread), pilot 

tube, the igniter wire from the igniter button, the two 
connectors attached to the TCO switch, and manifold 
tube at the gas control valve/thermostat. NOTE: L.P. 
Gas systems use reverse (left-hand) threads on the 
manifold tube. 

7.  Grasp the manifold tube and push down slightly to 

free the manifold, pilot tube, and thermocouple.

8.  Carefully remove the manifold/burner assembly from 

the burner compartment. NOTE: Be sure not to 
damage internal parts.
