Lighting Instructions
Read and understand these directions thoroughly before
attempting to light or re-light the pilot. Make sure the view
port is not missing or damaged (see Figure 20). Make sure
the tank is completely filled with water before lighting the
pilot. Check the rating plate near the gas control valve/
thermostat for the correct type of gas. Do not use this water
heater with any gas other than the one listed on the rating
plate. If you have any questions or doubts, consult your gas
supplier or gas utility company.
Note:
This water heater is powered by a thermopile sys-
tem.
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 sec-
onds, 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 your 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 49°C (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 pro-
cedure 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 20).
3. Continue clicking the Igniter button (for up to 90 sec-
onds) 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 tem-
perature setting. (“Hot” is approximately 49°C (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 20). (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 success-
fully light the pilot.
WARNING
Explosion Hazard
Replace view port if glass is missing
or damaged.
Failure to do so can result in death,
explosion or fire.
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 (see Figure
20).
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
20).
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 tempera-
ture setting. (“Hot” is approximately 40°C (120°F).)
