Emerson 37E73A-906 Shutting OFF the Appliance, Temperature Settings Display Approximate

INSTALLATION

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

!WARNING

Scald burns occur in under one second with 160°F water, which this thermostat will deliver if the temperature is set at “VERY HOT”. Lower settings of the temperature will reduce the risk of scald and will reduce your fuel bill.

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. They are the people most commonly hurt in scald injuries and in need of lower temperature and other protection like super- vision, point-of-use temperature control equipment or a sys- tem mixing valve. A point-of-use valve or system mixing valve can be obtained from your local plumber.

!WARNING

Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or impaired person unattended in a bathtub or shower. Scald burns can result

Checking the temperature setpoint may be performed at any time by the procedure described on step 1 of “Temperature Regulation” on page 3. No other action is needed for checking temperature setpoint.

SHUTTING OFF THE APPLIANCE

Vacation Shutdown

1.“Wake up” the temperature indicators by holding down both the COOLER and HOTTER temperature adjustment buttons at the same time for one second (see Figure

2). One or two of the temperature indicators will light up. Make a note as to which indicators are illuminated so that you can reset the control to the same setting when you return from vacation.

2.Press and release the COOLER button as many times as needed until the green leftmost indicator is only lit. This temperature setting is approximately 70°F. Leave the gas turned on.

3.When returning from vacation reset the temperature to that you noted in step 1.

Complete Shutdown

1.Turn off the electrical disconnect on the appliance, or remove the plug from the receptacle, whichever applies. (Don’t worry; the Intelli-Vent™ control will remember your correct temperature setting.)

2.Turn off the gas supply to the water heater. The water heater is now completely shut down.

3.To restart the water heater, follow the instructions in the section “Operating Instructions”.

There are no user serviceable parts in this control. The con- trol is supplied with tamper resistant screws. DO NOT attempt to repair or adjust the control. If you experience problems, discontinue use and replace the control immediately. Con- tinuing to use a damaged control could result in fire and/ or explosion.

Service

If you wish to verify that the water heater is operating properly:

1.Make sure there is power to the water heater.

2.Make sure that the gas is turned on to the water heater.

3.Initiate a call for heat by either drawing hot water from a nearby faucet or raising the temperature setting (see sec- tion “Temperature Regulation”).

4.Watch the ignition sequence and compare it to the “Se- quence of Operation” chart on page 6.

5.Note any error codes that appear and proceed to the next section “Troubleshooting”.
