Water Temperature Setting...
The following is additional information
which aid in determining a safe working
temperature to meet each household need.
Maximum water temperatures occur just
after the burner has shut off. To deter-
mine the water temperature, turn on a hot
water faucet and place a thermometer in
the water stream. If an adjustment to the
water temperature is preferred, then refer
to the Water Heater User Display – Opera-
tion Instructions for instruction on ad-
justing the local and remote user display
temperature setpoints.
A condition known as "stacking" or "layer-
ing" can occur when a series of short and
frequent hot water draws are taken. 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 hatter than the water toward the
bottom of the tank near the gas control
(thermostat). Therefore, always remem-
ber 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 con-
structed with a built in safety shut-off
device designed to shut off the gas supply
to the burner if the main burner is extin-
guished for any reason.
The gas control (thermostat) is also
equipped with a gas shut off device that
will shut off the gas supply to the burner if
the water heater exceeds normal operat-
ing 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 (shut-off) valve and do
not operate the water heater again until
it has been checked by a qualified service
technician.
NOTICE: Replace any part of the gas
control system which has been under
water.
