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
Vacation Shutdown
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.
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”.
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
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.
