Water Temperature Regulation
WARNING
The higher the temperature setting, the greater the risk
of scalding. Hot water can cause third degree burns in
under one (1) second at 160
o
F (71
o
C), in five (5) sec-
onds at 140
o
F (60
o
C), and in thirty (30) seconds at 130
o
F
(54
o
C). In households where there are children, physically
challenged individuals, or seniors, mixing valves for point
of use are necessary as means of reducing the scalding
potential of hot water.
When the water heater is plugged in for the first time, the
gas control valve will start to heat the water to the factory
adjusted temperature. To avoid any unintentional changes
in the water temperature settings, the gas control valve has
a tamper-resistant feature included for changing the tem-
perature setting. If you want to change this setting for either
cooler or warmer water, the following steps are necessary:
1. “Wake up” the temperature indicators by holding down
both the
COOLER
and
HOTTER
temperature adjust-
ment buttons at the same time for one (1) second (see
Lighting Instructions). One or two of the temperature
indicators will light up. These indicators will only remain
on for thirty (30) seconds, if no further buttons are
pressed. After thirty (30) seconds, the control will go
back to “Sleep” mode, and both buttons will again have to
be pressed to see the water temperature setting. Release
both of the temperature adjustment buttons.
See Figure
12
for an explanation of what each of the temperature indica-
tors mean.
To decrease the temperature
, press and release the
COOLER button once. The temperature indicators will now
display the new temperature setting. Press and release
the
COOLER
button until you have reached the desired
setting.
HOLDING DOWN THE BUTTON WILL
NOT CONTINUE TO LOWER THE SETTING
. The
button must be pressed and released for each tempera-
ture change desired.
To increase the temperature
, press and release
the HOTTER button once. The temperature indicators
will now display the new temperature setting. Press and
release the
HOTTER
button until you have reached the
desired setting.
HOLDING DOWN THE BUTTON
WILL NOT CONTINUE TO RAISE THE SETTING
.
The button must be pressed and released for each tem-
perature change desired.
To maximize the efficiency of this water heater and reduce
the risk of scalding, it is recommended that the gas control
valve be set at the setting below the large triangle (« »),
which represents approximately 120°F (49°C).
2. When you have completed setting the control, wait thirty
(30) seconds to see that the temperature indicators go
off and the control enters “Sleep” mode.
ALL OF THE
TEMPERATURE INDICATORS WILL BE OFF
DURING NORMAL OPERATION
. If at any time you
see the indicators on, there may be a problem with the
water heater and you should consult the Troubleshooting
Guide of this document, or contact a trained service profes-
sional.
When hot water is drawn from the tank in frequent
short bursts, a condition known as “stacking” is created.
“Stacking” is the result of increased cycling of the burner and
can produce very hot water temperatures at the hot water out-
let. Always remember to check the hot water coming out of
any faucet with your hand before use. This will reduce the
risk of scalding-related injuries.
