properly. To prevent water damage, the valve must be 
properly connected to a discharge line which terminates at 
an adequate drain. Standing clear of the outlet (discharged 
water may be hot), slowly lift and release the lever handle 
on the temperature and pressure relief valve to allow the 
valve to operate freely and return to its closed position. 
See Figure 21. If the valve fails to completely reset and 
continues to release water, immediately shut off the 
manual gas control valve and the cold water inlet valve 
and call a qualified technician.

6.  Disconnect the thermocouple (right-hand thread), pilot 
tube, the igniter wire from the igniter button, the two 
connectors attached to the thermal switch, and manifold 
tube at the gas control valve/thermostat. (Figures  22 
& 23.) 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.

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 (Figure 3).
2.   On the lower front of the water heater locate the gas 
control valve/thermostat (see Figure 23). Before per-
forming 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.(Figure 19).
