White Rodgers 927, 922 Operating Instructions, Temperature Regulation, Time to Cause, +10 Injury

INSTALLATION

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.

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.

Table 1. Temperature Settings

Display	Approximate	Approximate
	Temperature	Time to Cause
A B C	(+10oF)	Injury
	70 (Vacation)	N/A
	110
	115
	120	5 minutes
	125
	130	30 seconds
	135
	140	5 seconds
	145
	150	1.5 seconds
Flashing	160	Under 1 second

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.
