What to Do If You Smell Gas
• Turn the gas shut-off valve in the gas supply line to
the heater to ‘OFF’.
• Do not try to light any appliance.
• Do not touch any electric switch; do not use any
phone in your building.
• Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire
department.
If you do not smell gas, with the control switch at “ON”
position, you may proceed.
1. Turn the thermostat to the lowest setting and the
gas control switch to the “OFF” position.
2. Ensure the power cord is plugged in and correct
voltage is supplied to the appliance.
Important
When using soapy water solution or liquid leak test
solution around the control, do not splash any liquid on
the electric connections or electronic components of
the control. The control can be damaged. DO NOT use
a flame to detect gas leaks.
8. Turn the thermostat to the lowest setting. Main
burner will stop in approximately 20 seconds.
NOTE:
If the burner does not stop as described above, the
water temperature may be below the lowest tem-
perature that the thermostat is able to sense. (90°F
= 32°C). Wait until the water temperature has risen.
9. Re-cycle the system by turning the temperature
dial up toward the “HIGH” position to call for heat a
second time.
10. To check the lock–out on the ignition control, turn
the temperature dial to the lowest setting possible.
Wait for the heater to shut down completely. Then,
turn the gas control switch to “OFF” position.
11. Now turn the temperature dial to the maximum set-
ting.
12. The ignitor will be energized. However, since there
is no main gas flow, the burner cannot be lit. After
three trials, a lock–out will occur, deactivating the
system.
Re–settable Lock Out:
This condition is indicated by a flashing LED.
Gas Control
This heater is equipped with a combination gas con-
trol/ignitor. It will perform these functions:
1. Upon call for hot water, the gas control will energize
the ignitor which lights the main burner.
2. When the main burner is lit, the gas control will mon-
itor electronically the presence of a flame.
3. When the water temperature has been reached, the
gas control will turn off gas supply to the burner.
4. If a flame cannot be established within the trial for
ignition period, the control will stop the flow of gas.
The control will continue to energize the blower
(interpurge) and attempt ignition again. If a flame
cannot be established after three attempts, the con-
trol will lock-out. A red LED light on the control will
flash continually indicating a lock-out condition
occured. Unplugging the 120VAC power supply to
the water heater then restoring power will reset the
control.
NOTE: The control will perform a self-diagnostic check
upon start-up and the LED will flash 3-4 times.
During normal operation the LED remains off. A
solid red LED indicates that the control must be
replaced.
VI) FIRST LIGHTING
This appliance is equipped with an ignition device
which automatically lights the pilot. Do not try to light
manually with a match.
The temperature dial is adjusted to its lowest tem-
perature position when shipped from factory.
3. With the gas control switch “OFF”, check the sup-
ply gas pressure to the control:
Natural Gas at 7” W.C. pressure
Propane Gas at 11” W.C. pressure
4. Turn the gas control switch to fully “ON”.
5. Turn the thermostat to the desired setting, i.e. from
“Lower” toward “HIGH”. This will start the lighting
process:
a. The blower will be turned on after 20 seconds.
b. The ignitor will be at full glow after the next 17
seconds.
c. The main gas valve opens.
d. The main burner lights up, the flame envelops
the flame sensor, and the burner flame verifi-
cation process begins.
6. While the main burner is on, ensure the flame
envelopes 5/8” to 3/4” of the flame sensor.
7. While the main burner is on, again check all gas
connections with a soapy water solution. Correct
any poor connections that may be detected by the
presence of soap bubbles. Shut off electric and
gas supply before making such corrections.
CAUTION
Read before proceeding. If you do not follow
these instructions exactly, a fire or explosion may
result, causing property damage, personal injury
or loss of life.
