Operating Instructions, Burner | White Rodgers 37E37A-903 & 906

!CAUTION

Never use this water heater unless it is completely filled with water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning ON gas to the

water heater.

8.Open the gas shutoff valve.

9.BEFORE TURNING ON THE APPLIANCE, CHECK THE GAS LINES FOR LEAKS.

a.Use a soapy water solution. DO NOT test for gas leaks using a match or open flame.

b.Brush the soapy water solution on all gas pipes, joints, and fittings. Use care that excess solution does not enter the control’s plastic housing.

c.Check for bubbling soap. This means you have a leak. Turn OFF the gas and make the necessary repairs.

d.Turn on the gas and recheck for leaks. Repeat this process until you are sure the system is gas-tight. If repeated work on a part does not stop the leak, the part must be replaced.

e.Rinse off the soapy solution and wipe all the plumbing parts dry.

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 instructions 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 done either by turning on the disconnect switch to the water heater, or plugging in the water heater to a nearby outlet. The installer should have made this provision for you, and it must meet local and state ordinances of the National Electric Code, whichever applies.

INSTALLATION

5.For a brief (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 combination of indicators remain illuminated, either refer to the troubleshooting section of this manual, or contact a qualified 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 70oF. 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 2). 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 But- ton must be pressed and released for each tempera- ture change desired.

b.To increase the temperature press and release the HOTTER button once. The temperature indicators will now display the new temperature setting.
