Read and understand these directions thoroughly before 
attempting to light or re-light the pilot. Make sure the 
viewport is not missing or damaged. (See Figure 23) Make 
sure the tank is completely filled with water before lighting 
the pilot. Check the data plate near the gas control valve/
thermostat for the correct gas. Do not use this water heater 
with any gas other than the one listed on the data plate. 
If you have any questions or doubts, consult your gas 
supplier or gas utility company.
Lighting the Pilot:
1.  Read and follow the lighting instructions on the water 

heater’s label.

2.  Turn the Control Knob to Pilot. Press the Knob in fully and 

hold it in. (The knob will travel in about 1/4-inch if it is set to 
Pilot correctly.)

3.  Click the Igniter button continuously for up to 90 seconds 

or until the Status Light begins to blink. If the Status Light 
does not begin to blink after 90 seconds, STOP. Wait 10 
minutes before attempting to relight the Pilot. Repeat these 
steps 2-3 times, if necessary
The circuitry in this gas valve requires that you wait 10 
minutes between lighting attempts. If the Status Light 
blinks, release the Control Knob and turn it to the desired 
setting. (“Hot” is approximately 120°F).

If the Status Light Does Not Blink:
1.  Wait 10 minutes before another lighting attempt.
2.  If the Status Light did not blink, repeat the lighting 

procedure by following the lighting instructions on the water 
heater’s label. Remove the outer door
The Control Knob must be set to Pilot and held in 
continuously while clicking the igniter button (about once 
per second for up to 90 seconds). To observe the Pilot, 
remove the outer door and look through the view port (sight 
glass). See Figure 23.

3.  Continue clicking the Igniter button (for up to 90 seconds) 

until Pilot lights.

4.  Once the Pilot is lit, continue to hold the Control Knob in 

until the Status Light begins to blink.

5.  Release Control Knob and set Knob to desired temperature 

setting. (“Hot” is approximately 120°F.)

6.  Replace the outer door.
If the Pilot Does Not Light:
1.  Wait 10 minutes before another lighting attempt. If the pilot 

does not light, the Igniter may not be sparking or the unit 
may not be getting gas (or for a new installation, there may 
still be air in the gas line).
Each time you click the igniter button, you should be able 
to see the spark by looking through the view port.See 
Figure 23. (You may have to darken the room lights to see 

the spark.) You do not have to push the Control Knob in to 
check the Igniter button. Simply look through the sight glass 
while clicking the Igniter button and look for a spark. If you 
can’t see a spark when the Igniter button is clicked, check 
the wiring connections from the Igniter button and make 
sure that they are tight.

2.  If you see the Igniter spark, try relighting the pilot by 

following the instructions on the water heater’s label. 
Ensure that the gas supply is tuned on. There may be air in 
the gas line, and several lighting attempts may be needed 
to completely fill the line with gas and successfully light the 
pilot.

If the Pilot Lights but the Status Light Does Not Blink:
1.  If the pilot lights, continue to hold the Control Knob in until 

the Status Light blinks. If the pilot is lit and remains lit for 
90 seconds and the Status Light still does not blink, the 
thermopile connections may be loose, the thermal switch 
may need to be reset, or the thermopile may be defective.

2.  Remove the outer door.
3.  Press the reset button on the thermal switch (Figure 23).
4.  If switch clicks, it may have tripped. Do not light the Pilot 

if flammable vapors are present. Check flame arrestor for 
signs of discoloration (which could be caused by flammable 
vapors). If the flame arrestor is discolored, do not attempt 
to relight the Pilot. Have the water heater inspected by a 
qualified service technician.

5.  Check the wiring connections from the thermopile and the 

thermal switch to the gas control valve/thermostat.
Ensure that all wiring connections are tight. See Figure 23.

6.  Replace the outer door.
7.  Wait 10 minutes and try to light the Pilot according to the 

instructions on the water heater’s label.

8.  While clicking the Igniter button continuously, the Control 

Knob must be set to Pilot and held in until the Status Light 
blinks. Once the Status Light blinks, release the Control 
Knob and set the Knob to the desired temperature setting. 
(“Hot” is approximately 120°F.)
