Temperature Regulation
Due to the nature of the typical gas water heater, the water
temperature in certain situations may vary up to 30F ° (16.7 C °) higher or lower at the point of use such as, bathtubs, showers, sink, etc.
Any water heater's intended purpose is to heat water. Hot water is needed for cleansing, cleaning, and sanitizing (bodies,
dishes, clothing). Untempered hot water can present a scald
hazard. Depending on the time element, and the people involved (adults, children, elderly, infirm, etc.) scalding may occur at different temperatures.

HOTTER | 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 | infirm, | or physically/mentally |
| handicapped. | If |
anyone using hot | water | in your | home | fits | 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 | satisfies |
| your | hot | water | needs, a |
means such as a mixing valve, shall 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. Follow manufacturer's instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the
Temperature Regulation section in this manual. See Figures 21 and 22.
THE WATER HEATER SHOULD BE LOCATED IN AN AREA WHERE THE GENERAL PUBLIC DOES NOT HAVE ACCESS.
IF A SUITABLE AREA IS NOT AVAILABLE, A COVER SHOULD
BE INSTALLED OVER THE THERMOSTAT TO PREVENT
TAMPERING. Suitable covers are available through the Sears Service Center.
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: Awater temperature range of
is recommended by most dishwasher manufacturers.
The thermostat of this water heater has been factory set at its lowest position (OFF). It is adjustable and must be reset to the
desired temperature setting. The faceplate of the thermostat is
marked with approximate temperature settings. The preferred
starting point is approximately 120°F (49°C). Align the knob with
the desired water temperature as shown in Figure 21. There is a hot water scald potential if the thermostat is set too high. Some states have a requirement for a lower setting.
Turn the water temperature dial clockwise ( t_ ) to increase the
temperature, or counterclockwise ( _ ) to decrease the temperature.
Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
