Operating the water heater.
Water Temperature Setting…
Maximum water temperatures occur just after the burner has shut off. To determine the water temperature, turn on a hot water faucet and place a thermometer in the water stream.
To avoid any unintentional changes in water temperature settings, the gas control (thermostat) has a tamper resistant feature for changing the temperature setting. To change the temperature setting follow these instructions.
1."Wake Up" the temperature indicators by holding down both "COOLER" and "HOTTER" temperature adjustment buttons at the same time for one second, see Figure below. 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.
2.Release both of the temperature buttons.
a.To decrease the temperature press and release the "COOLER" button until the desired setting is reached.
b.To increase the temperature press and release the "HOTTER" button until the desired setting is reached.
NOTE: Holding down the button will not continue to lower or raise the temperature setting. The button must be pressed and released for each temperature change desired.
A condition known as “stacking” or “layering” can occur when a series of short and frequent hot water draws are taken.
Time/Temperature Relationship in Scalds
The hottest temperature water will be at the top of the tank, closest to the outlet pipe delivering hot water to the home.
Stacking can cause this top layer of water to be hotter than the water toward the bottom of the tank near the gas control (thermostat). Therefore, always remember to test the water temperature with your hand before use and remember that hotter water increases the risk of scald injury.
Also, always supervise young children or others who are incapacitated.
The gas control (thermostat) is constructed with a built in safety
The gas control (thermostat) is also equipped with a single use gas shut off device that will shut off the gas supply to the burner if the water heater exceeds normal operating temperatures. Refer to the Before You Call For Service section of this manual, or contact your dealer.
!WARNING: Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
If the water heater has been subjected to fire, flood or physical damage, turn off the manual gas control
NOTICE: Replace any part of the gas control system which has been under water.
