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 set temperature up to 140°F press and
release the “HOTTER” button until the
desired temperature is reached.
c. To set temperature above 140°F follow
these instructions:
i. Press and hold the “HOTTER” button
for a few seconds, until all temperature
indicator lights come on for one second and
then turn off.
ii. Now press and release the “HOTTER”
button until the desired temperature is
reached. The maximum temperature setting
is 160°F.
iii. To decrease the temperature press and
release the “COOLER” button until the
desired temperature is reached.
NOTICE: 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.
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.
Always supervise young children or others who are
incapacitated.
The gas control (thermostat) is constructed with a built
in safety shut-off device designed to shut off the gas
supply to the burner if the main burner is extinguished
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
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
(shut-off) valve to the appliance.
If the water heater has been subjected to fire, flood or
physical damage, turn off the manual gas (shut-off)
valve, and do not operate the water heater again until
is has been checked by a qualified service technician.
NOTICE: Do not use this appliance if any part
has been under water. Immediately call a qualified
installer or service agency to replace a flooded
water heater. Do Not attempt to repair the unit! It
must be replaced.
