OPERATING YOUR WATER HEATER
Lighting Instructions
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
WARNING

or damaged.
Failure to do so can result in death,
explosion or fire.
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.)
