Shutting OFF the Appliance, Vacation Shutdown

!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.

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

Checking the temperature setpoint may be performed at any time by the procedure described on step 1 of “Temperature Regulation” on page 4. No other action is needed for check- ing temperature setpoint.

SHUTTING OFF THE APPLIANCE

!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

1.“Wake up” the temperature indicators by holding down both the COOLER and HOTTER temperature adjustment but- tons 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.

INSTALLATION

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 control is supplied with tamper resistant screws. DO NOT attempt to repair or adjust the control. If you experience prob- lems, discontinue use and replace the control immediately.

Continuing 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 7.

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