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.

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 satisfies 

your hot water needs. This will also provide the most energy efficient 

operation of the water heater.

Figure 20 shows the approximate water temperatures produced at 

various thermostat settings. Short repeated heating cycles caused by 

small hot water uses can cause temperatures at the point of use to 

exceed the thermostat setting by up to 30°F (17°C). If you experience 

this type of use you should consider using lower temperature settings 

to reduce scald hazards.

Valves for reducing the point-of-use temperature by mixing cold and 

hot water are available, see Figure 2. Also available are inexpensive 

devices that attach to faucets to limit hot water temperatures. Contact 

a licensed plumber or the local plumbing authority.

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 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 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 thermostat, read the “Temperature Regulation” section in this 

manual, see Figure 20.

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.  If a suitable area is not available, a cover 

teMperature reGulatIon

should be installed over the thermostat to prevent tampering.

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 

risks  of  scalds.  Some  states  require  settings  at  specific  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 20. 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.
