Temperatures are
approximate.
All temperatures listed on the water heater's gas
control/thermostat are approximate.
Maximum water temperatures occur just after the water
heater has completed a heating cycle. To determine
the water temperature at point-of-use, open a hot water
faucet and hold a thermometer under the stream of
water.
Frequent, short uses of hot water can cause a
phenomenon called stacking, when the temperature
of the water at the top of the tank (closest to pipes
delivering water to the home) exceeds the temperature
at the bottom of the tank (where the gas control/
thermostat is located).
Before use, always test the water temperature with your
hand, keeping in mind that hotter water increases the
danger of scalding.
NOTE: Refer to Water Temperature in Safety
Information, page 5.

STATUS
The gas control/thermostat is equipped with two safety
shut-off devices:
• One is designed to shut off gas to the water heater's
burner if the pilot light goes out.
• The other is designed to shut off gas to the burner if
the water heater exceeds normal temperatures.
If one of these safety shut-off devices is activated, refer
to Troubleshooting Tips, page 20.
WARNING
Should overheating occur or the gas
supply fails to shut off, turn off the manual gas control
valve to the appliance. Turn off gas to the water heater
if it has been subjected to overheating, fire, flood or
physical damage. (Refer to Lighting and Shutdown,
page 7.) Do not operate the water heater again until
it has been thoroughly checked by a qualified service
technician. Do not use this appliance if any part has
been under water. Immediately call a qualified service
technician to inspect the appliance and to replace any
part of the control system and any gas control which has
been under water.
