TEMPERATURE REGULATION
Due to the nature of the typical gas water heater, the water
temperature in certain situations may vary up to 30°F (16.7°C)
higher or lower at the point of use such as, bathtubs, showers,
sink, etc.
HOT WATER CAN SCALD: Water heaters are intended to produce
hot water. Water heated to a temperature which will satisfy space
heating, clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact. Some
people are more likely to be permanently injured by hot water
than others. These include the elderly, children, the infi rm, or
physically/mentally disabled. If anyone using hot water in your
home fi ts into one of these groups or if there is a local code or
state law requiring a certain temperature water at the hot water
tap, then you must take special precautions. In addition to using
the lowest possible temperature setting that satisfi es your hot
water needs, a means such as a mixing valve should be used at
the hot water taps used by these people or at the water heater.
Mixing valves are available at plumbing supply or hardware stores,
see Figure 2. Follow manufacturer’s instructions for installation of
the valves. Before changing the factory setting on the gas control
valve/thermostat, see Figure 28.
Never allow small children to use a hot water tap, or to draw
their own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
NOTE: A water temperature range of 120°F-140°F (49°C-60°C)
is recommended by most dishwasher manufacturers.
The water temperature setting was factory set at the lowest
temperature; Pressing the “COOLER”
button decreases
temperature and pressing the “HOTTER” button increases
the temperature.
Setting the water heater temperature at 120°F (49°C) (Approx.
“ ” mark on temperature setting of gas control valve/thermostat)
will reduce the risk of scalds. Some states require settings at
specifi c lower temperatures.
To avoid any unintentional changes in water temperature settings,
the gas control valve/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 28. 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 adjustment 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.
Should overheating occur or the gas supply fail to shut off, turn
off the manual gas control valve to the appliance.
