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 

Regulation” on page 4. No other action is needed for check-
ing temperature setpoint.

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. 

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.

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”.
