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.
It is recommended that lower water temperatures be used to avoid the
risk of scalding. It is further recommended, in all cases, that the water
temperature be set for the lowest temperature which satisfi es your hot
water needs. This will also provide the most energy effi cient operation
of the water heater.
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 handicapped. 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 15.
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 Figure 26.
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.
The water heater should be located in an area where the general public
does not have access.
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 valve) 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
control 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 26. 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.
