b. To increase the temperature press and release the
HOTTER button once. The temperature indicators will
now display the new temperature setting.
Press and release the HOTTER button until you have
reached the desired setting. HOLDING DOWN THE BUTTON
WILL NOT CONTINUE TO RAISE THE SETTING. The Button
must be pressed and released for each temperature change
desired.
To avoid scald injury, set the control to the lowest setting
which will deliver your needed hot water. Refer to Table 1 to
determine the approximate temperature setting, and the ap-
proximate time for scald injury at that temperature.
3. When you have completed setting the control wait 30
seconds to see that the temperature indicators go off and
the control enters “Sleep” mode. ALL OF THE TEMPERA-
TURE INDICATORS WILL BE OFF DURING NORMAL
OPERATION. If any time you see the indicators on, there
may be a system error and you should consult the “Trou-
bleshooting” section of this document, or contact a trained
service professional.
If you use hot water frequently and in short spurts, water tem-
perature can occasionally exceed the temperature setting by
up to 30°F because of the dynamics of the appliance. Keep
this in mind when you are selecting a temperature higher than
the factory default setting.
Be sure to protect babies and the infirm or others with im-
paired mobility who cannot get out of the hot water quickly.

OPERATING INSTRUCTIONS
1. The control uses an automatic ignition system to light
the burner. DO NOT TRY TO MANUALLY LIGHT THE
BURNER.
2. Wait at least five (5) minutes to clear out any gas, and
then smell around the appliance area near the floor. If you
smell gas, STOP! Follow the instructions “What to do if
you smell gas” on the first page of this instruction sheet.
If you do not detect gas, continue with the next step.
3. Make sure that both the inner and outer doors are in place.
These doors are located where the burner tube enters the
water heater at the bottom. Both doors must be in place
for safe operation.
4. Turn on power to the water heater. This can be done either
by turning on the disconnect switch to the water heater,
or plugging in the water heater to a nearby outlet. The in-
staller should have made this provision for you, and it must
meet local and state ordinances or the National Electric
Code, whichever applies.
5. For a brief time (one to five seconds) all of the indicators
on the front of the control should come on, and then turn
off. This indicates that the control has completed the self-
diagnostic test, and is ready for operation. If any combi-
nation of indicators remain illuminated, either refer to the
troubleshooting section of this manual, or contact a quali-
fied service person.
6. The water heater is now ready for operation, and will
begin to heat the water to the factory default setting of
approximately 70°F. If an alternate temperature setting is
required, please refer to the following section “Temperature
Regulation”.
TEMPERATURE REGULATION
After the gas and electrical connections are made and the
water heater tank is full of water, the control will now start to
heat the water to the factory default setting of approximately
70°F. If a higher setting is desired, start with the setting at the
triangle ( ). This is approximately the 120°F setting, and the
safest and most economical setting for the water heater.
To change the temperature setting for either cooler or warmer
water, the following steps are necessary:
1. “Wake up” the temperature indicators by pressing the
COOLER and HOTTER temperature adjustment buttons at
the same time and releasing after one second (see Figure
4). One or two of the temperature indicators will light up.
These indicators will only remain on for 30 seconds if no
further buttons are pressed. After 30 seconds the control
will go back to “Sleep” mode, and both buttons will again
have to be pressed to see the water temperature setting.
2. If this is the first time that the control has been used, the
leftmost green indicator will be illuminated indicating the
water temperature setting of approximately 70°F. See Table
1 for an explanation of what each of the temperature indi-
cators mean.
a. To decrease the temperature press and release the
COOLER button once. The temperature indicators will
now display the new temperature setting. Press and
release the COOLER button until you have reached the
desired setting. HOLDING DOWN THE BUTTON WILL
NOT CONTINUE TO LOWER THE SETTING. The
Button must be pressed and released for each tem-
perature change desired.
