tight in the gas control valve/thermostat.  Finally, start 
the thermocouple nut and turn it all the way in by hand.  
An additional quarter turn with a 3/8” open-end wrench 
will then be sufficient to seat the lockwasher.  When 
you are finished, connect the two wire leads that go to 
the thermal switch.
7.  Reconnect the igniter wire.
8.  Turn gas supply on and refer to the Lighting Instruc-
tions.
9.  With the burner lit, check the gas control valve/
thermostat supply line, two piece wire connector, 
manifold tube, and pilot tube connections for 
leaks. Check for leaks by brushing on an approved 
noncorrosive leak detection solution. Bubbles forming 
indicate a leak. Correct any leak found. IMPORTANT: 
All leaks must be fixed immediately.
10.  Replace the outer door.

Piezoelectric Igniter System                                   
The piezoelectric igniter system consists of the igniter 
button, electrode, and wire.  The pilot is ignited by an 
electric spark generated when the igniter button is 
pressed. The spark gap of 0.125 inch is set when the 
electrode is installed at the factory. (Figure 32 ). Use 
only factory authorized piezoelectric igniter parts for 
replacement.

Testing the Igniter System                                      
Turn off the gas to the water heater at the manual gas 
shut-off valve. Watch the electrode tip while activating the 
igniter. A visible spark should jump from the electrode. To 
avoid shock, do not touch the burner or any metal part 
on the pilot or pilot assembly. If no spark is visible, check 
the wire connections and make sure the electrode is not 
broken. Replace the igniter if defective. Dirt and rust on the 
pilot or electrode tip can prevent the igniter spark. Wipe 
clean with a damp cloth and dry completely. Rust can be 
removed from the electrode tip and metal surfaces by 
lightly sanding with an emery cloth or fine grit sandpaper.
Removing and Replacing the Gas Control 
Valve/Thermostat                                                             
IMPORTANT: This water heater has a resettable thermal
switch installed. Do not attempt to disable or modify this
feature in any way. Use only factory authorized 
replacement parts.
Removing the Gas Valve:
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 
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.  Drain the water heater. Refer to the section of 
“Draining and Flushing” section and follow the 
procedure.
5.  Disconnect the piezo igniter wire from the piezo igniter 
button. NOTE: There are two types of igniters. If 
you have the square igniter, slide the igniter bracket 
backwards away from the gas valve to remove it. If 
you have the round igniter, first remove the igniter 
from the bracket by depressing front and rear holding 
tabs and lift. Next remove igniter bracket from the 
gas valve. Disconnect the thermocouple, pilot tube, 
the two connectors attached to the thermal switch, 
and manifold tube at the gas control valve/thermostat 
(Figure 22). NOTE: L.P. gas systems use reverse (left-
hand) threads on the manifold tube.
6.  Refer to “Gas Piping” section (Figure 3) and disconnect 
the ground joint union in the gas piping. Disconnect the 
remaining pipe from the gas control valve/thermostat.
7.  To remove the gas control valve/thermostat, thread a 
correctly sized pipe into the inlet and use it to turn the gas 
control valve/thermostat (counterclockwise.) Do not use 
pipe wrench or equivalent to grip body.  Damage may 
result, causing leaks. 
 
Do not insert any sharp objects into the inlet or outlet 
connections. Damage to the gas control valve/thermostat 
may result.
